Specifically,\r\nit aims to explore the potential of ultrasonic acoustic imaging to identify and monitor various plastic\r\ndeformation mechanisms in stainless steel and aluminum. The selection of materials is based on their distinct\r\nplastic deformation behaviors: aluminum releases internal energy through dislocation mechanisms, while\r\nstainless steel releases energy through deformation, first by dislocation and then by twinning. To achieve\r\nthis goal, the study will continuously measure changes in sound velocity and the nonlinear acoustic parameter\r\n&#946; while subjecting the materials to uniaxial tensile tests at different levels of applied stress.\r\nPrevious studies conducted by our research group have demonstrated that changes in sound velocity, in\r\nrelation to strain, offer a reliable means of quantifying dislocation density in local measurements on\r\naluminum, copper, and stainless steel specimens. Furthermore, these studies have observed that alterations\r\nin the nonlinear acoustic parameter, specifically second harmonic generation, exhibit more pronounced\r\nchanges compared to variations in linear acoustics (speed of sound). Building upon these findings, the\r\nproposed research involves the generation of both linear and nonlinear acoustic images over wider spatial\r\nregions to advance our understanding of the plastic behavior of materials undergoing different\r\nmicrostructural changes.\r\nThe challenge of applying the results of this research to in situ measurements in the industry is not trivial,\r\nas the highly controlled laboratory conditions are not maintained in service components. In this regard, the\r\nincorporation of machine learning tools in the proposal aims to identify the parameters most sensitive to the\r\nvarious deformation mechanisms through clustering techniques. It is expected that the correlation of different\r\nacoustic parameters with the various plastic deformation mechanisms of both materials under study will\r\ngenerate an optimal database that reflects the variety of scenarios present in service components, thus\r\npaving the way for the industrial use of the proposed characterization system.\r\nThe adoption of diagnostic techniques and the utilization of metallic material state analysis in service\r\nsignificantly enhance our ability to comprehend and control plastic deformation mechanisms, contributing to\r\nimproved material reliability and robustness, and facilitating informed decision-making and maintenance\r\nstrategies.\r\nAdditionally, ex-situ standard microstructural tests, including XRD (X-ray diffraction), EBSD (electron\r\nbackscatter diffraction), and TEM (transmission electron microscopy), will be performed to characterize the\r\nmaterial\u0092s state after deformation. These complementary tests will provide valuable microstructural\r\ninformation, enabling the correlation of deformation states with the acquired acoustic images.\r\nAll the acoustic and microstructural information described above, in conjunction with previous research group\r\ndata, will be stored in a robust and comprehensive database. This database will serve as the input for a\r\nMachine Learning algorithm, which will facilitate the identification of patterns of correspondence between\r\nacoustic and microstructural parameters. This approach aims to enable the future prediction, with a high\r\nlevel of probability, of the specific type of plastic deformation mechanism that a material is undergoing based\r\non the acoustic parameter measurements.\r\nThe successful development of this research proposal would yield several significant outcomes. Firstly, it\r\nwould enable the early detection of microstructural changes in materials long before fractures occur.\r\nMoreover, it would establish a non-intrusive tool for characterizing materials by identifying the underlying\r\nmechanisms driving plastic deformation and monitoring the evolution of materials in service over time.\r\nUltimately, this research has the potential to advance our understanding of the plastic behavior of stainless\r\nsteel and aluminum, opening avenues for improved analysis, design, and performance evaluation of materials\r\nin various industrial applications.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Investigador\/a Responsable<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #EFB956\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 1250472<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Abril 2025 - Marzo 2029<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#EFB956 !important; color:#FFF\">Adjudicado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9366\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            The stability of austenite in medium Mn steels\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9366\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9366\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]Medium manganese steels (MMnS) are currently a subject of active scientific research due to a number of\r\nreasons. First, their unique combination of strength and ductility makes them promising candidates for\r\nlightweight structural applications in automotive and aerospace industries, where reducing weight without\r\nsacrificing mechanical properties is critical. Second, their ability to retain austenite at room temperatures\r\noffers advantages in terms of formability and resistance to hydrogen embrittlement, which are significant\r\nchallenges in steel manufacturing. Third, medium Mn steels have shown potential in enhancing wear and\r\nimpact resistance, making them suitable for applications in mining, construction, and machinery sectors.\r\nAdditionally, their corrosion resistance and potential for cost-effective alloying with other elements further\r\nexpand their utility across various engineering fields. Scientific research on medium Mn steels aims to\r\noptimize their microstructure, processing parameters, and alloy compositions to unlock their full potential,\r\nthereby contributing to the development of advanced materials that meet the performance requirements of\r\nmodern industries while promoting sustainability and efficiency in manufacturing processes.\r\nThe proposed research aims to investigate the stability of austenite in medium manganese steels within\r\nternary Fe-C-Mn and Fe-C-Mn-X systems (X: Al, Si, Cr), focusing on its correlation with processing\r\nparameters. The primary objective is to assess the stability of austenite via (i) experimentally determining\r\nthe martensite start temperature (thermal stability) using dilatometry and thermal analysis techniques, and\r\n(ii) to evaluate the fraction of austenite as a function of strain (mechanical stability) under tensile test. These\r\nmeasurements will provide crucial data to understand how variations in processing conditions influence\r\naustenite stability. Else, the study will correlate austenite stability with mechanical properties through\r\nmechanical tests and in-depth microstructural characterization, aiming to establish predictive models.\r\nAdditionally, thermodynamic and kinetic calculations will aid in assessing the phase transformation behavior\r\nunder different thermal histories. The research will extend its scope to evaluate impact and wear properties\r\nin relation to austenite stability, crucial for applications in industries requiring high strength and toughness,\r\nsuch as mining and construction.\r\nBy systematically exploring these relationships, the project seeks to advance the fundamental understanding\r\nof medium Mn steels, potentially leading to the development of lightweight, durable materials with enhanced\r\nperformance characteristics. Ultimately, the findings aim to contribute to the optimization of steel\r\nmanufacturing processes and the realization of more efficient and reliable engineering solutions in demanding\r\noperational environments[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Co-Investigador\/a<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #48A2F9\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 1241649<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Abril 2024<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#48A2F9 !important; color:#FFF\">En Ejecuci\u00f3n<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9358\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            DICATIONIC DERIVATIVES OF AZOBENZENE AS PHOTOACTIVE SURFACTANTS FOR DRUG TRANSPORT SYSTEMS: STUDY OF PHOTOREVERSIBLE BEHAVIOR AND LOAD CAPACITY IN MOLECULAR AGGREGATES\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9358\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9358\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]This project aims to investigate how structural modifications of a dicationic derivative of azobenzene can\r\naffect the drug release and load capacity of its photoactive molecular aggregate.\r\nTo evaluate this, three types of structural modifications are proposed.

More specifically, whether it is possible to use ultrasound to reliably\r\ncharacterize the plasticity deformation mechanism---slip, TWIP, TRIP---of Fe80-xCo10Cr10Mnx. To this end,\r\nthe speed of sound will be measured, continuously, as a function of applied stress in uniaxial tensile tests.\r\nIn previous work, proposers have shown that the speed of sound as a function of stress provides a reliable\r\ntool to measure dislocation density in aluminum, copper, and stainless steel. In the latter case, it has also\r\nbeen shown to reliably discriminate between slip and twinning as a deformation mechanism. It is now\r\nproposed to study the possibility of extending this capability not only to new materials, HEAs, but also to a\r\nnew mechanism, phase transformation.\r\nWe will start with the materials whose plastic deformation is slip-dominated, since we have robust experience\r\nin this case. We shall then move to the TWIP material, where our more recent experience will be brought to\r\nbear, to end up with the unexplored, from the point of view of ultrasound, TRIP material. Samples for tensile\r\nloading will be prepared. They will be tested using a universal testing machine and ultrasound measurements\r\nof longitudinal wave velocity will be carried out in-situ. A decrease in the wave velocity as a function of\r\napplied stress will indicate a proliferation of dislocations; the dislocation density will be determined as a\r\nfunction of stress as will the parameters of Taylor's rule. An increase in wave velocity as a function of stress\r\nwill indicate a decrease in average grain size. Modeling will be applied to determine whether this is due to\r\ntwinning or phase transformation. These results will also be validated with post-mortem XRD, TEM, and\r\nmetallography measurements, as well as ex-situ acoustic measurements.\r\nThe success of the proposed research would have short-term and long-term benefits: In the short term it\r\nwould provide a non-intrusive tool---ultrasound---to assist in the search for HEAs with pre-determined\r\nproperties, as needed for specific applications. In the long-term, it would pave the way for the development\r\nof a practical, non-intrusive, tool for the evaluation of HEA pieces in service.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Co-Investigador\/a<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 1220058<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Abril 2022<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9360\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            UNDERSTANDING THE STRUCTURE-PROPERTY RELATIONSHIPS ON ADVANCED HIGH STRENGTH STEELS OBTAINED VIA CHEMICAL PATTERNING OF AUSTENITE\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9360\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9360\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]Society is facing an unprecedented challenge in terms of combining sustainability, economic growth and\r\ntechnological development. The industry has tackled these demands by developing novel products and\r\ninnovative service strategies, taking the maximum advantage of the installed capabilities and cutting edge\r\ntechnologies. Steel industry has taken the lead by supporting internal research and scientific collaborations\r\nworldwide, enabling an ever increasing number of scientific developments. Steel plays a major role as the\r\nbackbone material of civilization for a number of reasons, namely (i) abundance, (ii) relatively cheap, (iii)\r\nwide range of properties and applications, (iv) 100% recyclable, (v) potential to improve in-service\r\nperformance.\r\nIn the framework of (v), the current proposal aims to provide new grades of steel by means of chemical\r\npatterning of austenite. The concept of austenite patterning consists in producing layers in the microstructure\r\nwith a chemical composition different from the bulk composition, via specific alloying elements and thermal\r\ncycles. These layers, after fully austenitization, deliver transformation products on cooling different than\r\nexpected from the average austenite, allowing a new degree of freedom for tailoring of microstructures. So\r\nfar there is only one scientific paper on the subject, which has reported outstanding mechanical strength\r\n(ultimate) of ca. 2 GPa, with uniform elongations of 7% in a lamellar martensite-austenite microstructure in\r\na single 0.51C-4.35Mn steel.\r\nThe present proposal sets a detailed working plan to investigate the impact of the initial microstructure and\r\nthermal path upon the chemical patterning of austenite in a number of different steel chemistries. The aim\r\nis two-folded: to analize the evolution of the phase transformations at different stages of the process as a\r\nfunction of the initial microstructure and heat-treatment parameters, and to gain fundamental insights on\r\nthe mechanical behavior of the new steel grades. It is hypothesized that the correct interplay of the\r\nparameters mentioned above can yield optimized final microstructures with enhanced in-service\r\nperformance.The methodology incorporates up-to-date assessment tools of thermodynamic equilibria and\r\nkinetics (ThermoCalc & Dictra) in selected steel chemistries, accurate tracking of phase transformations via\r\nDilatometry experiments, in-depth characterization of the microstructure and mechanical properties and insitu\/ex-situ ultrasound probing of tensile test specimens to better understand the hardening mechanisms.\r\nThe experimental results will be compared with modeling strategies for both phase transformations and\r\nmechanical behavior.\r\nThe expected results of the proposal will be of interest to the scientific community due to the novelty of the\r\nexperimental concept and the potential contribution to the understanding of structure-property relations.\r\nElse, the findings will be of significance for the design of structural parts, such as high strength and impact\r\ntoughness for car body crash worthiness. In the case of Chilean mining industry, wear and impact wear\r\nresistance are potential applications of the new steel grades to be tested. The proposal is lay out within a\r\nnovel cooperation framework between a group of specialists on specific aspects of materials science (phase\r\ntransformations in steel, constitutive modeling, ultrasound probing), oriented to contribute to the\r\nfundamental understanding of the microstructure-property relations resulting from chemical patterning of\r\naustenite. Additionally, three universities and one industrial partner (University of Twente, The Nederland,\r\nGent University, Belgium; University of Alberta, Canada; and ME Elecmetal, Chile-US, respectively) are\r\nsupporting the proposal with resources such as workshops, sample preparation, specific characterization\r\ntechniques, software for post-processing, among others.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Co-Investigador\/a<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 1210841<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Abril 2021 - Marzo 2025<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9361\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            UTILIZATION OF PHOTO-FENTON AND ULTRASOUND PROCESSES IN THE DEPURATION OF LANDFILL LEACHATE\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9361\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9361\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]The importance of water for life is indisputable. Nevertheless, water quality and availability are affected by\r\nincreases in consumption and climate change. Indeed, several areas of Chile are suffering acute water\r\nscarcity. Consequently, there is a critical need to develop efficient technologies for wastewater recovery.\r\nHowever, considerations must be given to the fact that some wastewaters have toxic recalcitrant pollutants\r\nrequiring complex treatments, such as landfill leachate (LL). The general goal of the project is to evaluate\r\nthe viability of experimentally improving LL quality by conjointly using the solar photo-Fenton process and\r\nultrasound (US), thereby enhancing photocatalysis, ultimately reducing wastewater toxicity.\r\nThe specific goals are to (i) measure the H2O2 and UV irradiation produced by US in LL (laboratory scale);\r\n(ii) evaluate the hydroxyl radicals generated during treatment processes (laboratory scale); (iii) maximize\r\norganic-pollutant removal in LL by defining the optimal operating conditions for the photo-Fenton\/US process\r\n(laboratory scale); (iv) maximize organic-pollutant removal in LL by defining optimal US power\/frequency in\r\nthe sonolytic process (pilot-plant scale); and (v) evaluate toxicity elimination and energy consumption in LL\r\ntreatments with solar-photocatalytic and US processes (laboratory and pilot-plant scales). The proposed\r\ninvestigation will use a scientific methodology, developing reproducible methods to observe the effects of\r\ndiverse parameters, all with a focus on maximizing contaminants removal. To characterize LL, several\r\nparameters will be evaluated, including chemical oxygen demand, biological oxygen demand, total organic\r\ncarbon, total dissolved nitrogen, pH, metals, ammonia, colour, biodegradability, toxicity, total suspended\r\nsolids, conductivity and humic acid.\r\nTo determine the amount of H2O2 generated by US in a simulated LL, a set of experiments will be run\r\nto produce the sonochemical process, applying different US frequencies (100 kHz, 200 kHz and 300 kHz)\r\nand powers (100 W, 170 W and 250 W), thus obtaining the kinetic reaction to H2O2 production. The\r\namount of UV irradiation formed due to sonoluminescence will be quantified in the same beaker in\r\nthe simulated LL. Sonoluminescence intensity during the runs will be measured using a spectro-radiometer.\r\nTo evaluate the hydroxyl radicals (\u00b7OH) generated in the simulated LL during treatment processes,\r\na method based on the oxidation of 2-proponol will be used. To determine the optimal operating\r\nconditions for the photo-Fenton\/US process to maximize the removal of organic pollutants\r\npresent in the simulated LL, a set of experiments will be carried out in the same photoreactor (1 L),\r\napplying different reagent concentrations, treatment times, and pH levels. To establish optimal US power\r\nand frequency in the sonolytic process to maximize the removal of organic pollutants present in\r\na real LL (after its pretreatment), a set of runs will be carried out at pilot-plant scale in a solar\r\nphotoreactor compound parabolic concentrator (CPC; 12 L useful volume). To evaluate toxicity\r\nelimination from the real LL an Aliivibrio fischeri test, respirometer assay, and phytotoxicity assay will be\r\nused, followed by determining median effective concentrations (EC50) according to the Probit model. Since a\r\nmain disadvantage of the proposed treatments is high-energy consumption, specific energy consumption\r\n(SEC) and electrical energy per order (EEO) will be determined for all processes. All experiments will be done\r\nin triplicate, and filtration and coagulation\/flocculation processes as a pretreatment will be used prior to all\r\nruns. The expected results of the proposed project are to (i) obtain new knowledge related to joint photo-\r\nFenton and ultrasound wastewater treatments, (ii) demonstrate treatment synergies, and (iii) validate the\r\nuse of advanced oxidation processes for improving LL. Project results will be reported in papers, through\r\nthesis work, and at scientific congresses, strengthening national and international research networks.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Co-Investigador\/a<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 11190900<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Noviembre 2019<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9362\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            REAL TIME CORRELATION BETWEEN THE STRAIN RATE IN STANDARD MECHANICAL TESTS AND MICROSTRUCTURAL CHANGES IN METALS: AN ACOUSTIC POINT OF VIEW\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9362\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9362\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]Dislocations are the main source of plastic behavior of metals, however, it is very difficult to quantitatively\r\nstudy their influence. In order to improve this situation, it is proposed to use its interaction with elastic waves\r\nas a non-invasive probe in Aluminum and Steel 304L at different strain-rates. The long-term objective of the\r\nresearch presented in this proposal is to obtain a standardized methodology for the characterization of\r\nmaterials by means of ultrasonic tests.\r\nThe proposed technique is based on in-situ measurements of wave pulse propagation in rectangular samples\r\n(with ASTM Standard) under standard tensile tests, with maximum deformations of the order of 3% to 7%,\r\nwhich includes both the elastic regime and the plastic, additionally considers traction speeds between 0.001\r\nmm \/ s and 0.5 mm \/ s. The results are contrasted with measurements of ultrasonic resonance spectroscopy\r\n(RUS) and density measurements of dislocations by XRD of pieces of the material obtained from the test\r\npieces under traction study, which will be carried out in collaboration with Prof. Claudio Aguilar of the\r\nUniversity Santa Maria. We will also explore a correlation of the results with the microstructural\r\ncharacterization using TEM images\r\nOn the other hand, it is proposed to implement non-linear measures in-situ during tensile tests, which have\r\nbeen shown to be much more sensitive to the presence of dislocations of a material. The non-linear\r\nmeasurements are based on the application of a continuous ultrasonic wave and the analysis is performed\r\non the amplitude of the first harmonic A2&#969; as a function of the amplitude of incident mode A&#969;, those that\r\nare related of the form A2&#969; = &#946;A&#969;, with &#946; a non-linear parameter. For this analysis it is proposed to develop\r\nthe theory, until now non-existent, between the non-linear parameter and the density of dislocations in\r\ncollaboration with Prof. Fernando Lund of the Physics Department of the FCFM of the University of Chile.\r\nEmphasis will then be placed on in situ measurements, where a quantitative and continuous relationship\r\nbetween the density of dislocations and the stress applied during a tensile test has recently been found, as\r\nwell as an indication of universality and independence of the initial condition once that the system enters the\r\nplastic deformation regime.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Investigador\/a Responsable<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 1191179<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Abril 2019 - Abril 2022<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9363\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            ULTRASOUND AS A PROBE OF PLASTICITY IN STEELS\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9363\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9363\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]Dislocations are at the source of plastic behavior of metals and alloys, yet it is very difficult to quantitatively study their behavior. In order to improve this situation, it is proposed to use their interaction with elastic waves as a nonintrusive probe. The long-term aim of the research presented in this proposal is to enable the development of ultrasound technology as a practical non-intrusive tool for the characterization of plastic behavior of materials.\r\nIn recent years, proposers have shown, using Resonant Ultrasound Spectroscopy (RUS), that an increase of dislocation density in aluminum by a factor of 6 leads to a change for the speed of shear waves on the order of 1%, a quantity that can be measured with an accuracy on the order of 0.1%. They have also shown that local measurements of the speed of shear waves in aluminum under standard testing conditions in tension provide a quantitative, accurate, nonintrusive and continuous relation between dislocation density and externally applied stress, and that an increase in dislocation density by a factor of ten in copper and aluminum leads to an increase in the value of the (nonlinear) parameter that characterizes second harmonic generation by 20 to 60%.\r\nThis proposal seeks to go one more step towards a practical implementation of the proposed ultrasonic testing tool for pieces in service. Materials of wide use in industry, 304L steel and TWIP steel, will be used. And in addition to bulk ultrasonic and shear waves, surface Rayleigh waves will be tested, in order to develop techniques that are useful when pieces in service have a geometry that does not lend itself to bulk wave measurement. Both linear (wave propagation velocity and attenuation) and nonlinear (second harmonic generation) acoustics measurements will be performed, using bulk and surface waves, ex situ after mechanical treatment, and in situ under standard testing conditions. In addition, dislocation density will be measured using X-ray diffraction (XRD) , using both the modified Warren-Averbach and Rietveld methods. Additional characterization will be performed using transmission electron microscopy (TEM) and scanning electron microscopy (SEM).\r\nThe expected result of the proposed research is a set of measurements that relate acoustics parameters to dislocation density in 304L and TWIP steels. The specific goal is that these measurements will provide a framework for the development of devices to nondestructively measure the dislocation density of pieces in service.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Co-Investigador\/a<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"  circle--pattern-bottom-large col-sm-12 col-md-12 img-article\"><div class=\"holder-publish col-md-12\" style=\"border-bottom: 1px solid #35DB54\"><div class=\"content-holder h-100 component-border overflow-hidden row m-0 p-4 aling-items-center\"><ul class=\"p-0 list-style-none\"><li class=\"p-0 ms-1 me-2\"><i class=\"fa fa-solid fa-id-card-clip fa-fw\"><\/i> 3160164<\/li><li class=\"p-0 ms-1\"><i class=\"fa fa-regular fa-calendar fa-fw ms-1\"><\/i>Noviembre 2015<\/li><\/ul><div class=\"caption col-12 p-0 col-md-12 row m-0 align-items-center\"><div class=\"px-md-1\"><small class=\"badge rounded-pill fw-semibold\" style=\"background-color:#35DB54 !important; color:#FFF\">Finalizado<\/small><small class=\"ms-2 badge rounded-pill fw-semibold\" style=\"background-color:#F0F1F3 !important; color:#797979\"><i class=\"fa fa-solid fa-lg fa-money-check-dollar fa-fw me-1\"><\/i>Agencia Nacional de Investigaci\u00f3n y Desarrollo - ANID<\/small>\n                            <div class=\"accordion accordion-flush\" id=\"9364\">\n                                <div class=\"accordion-item\">\n                                    <h3 class=\"my-0 small-space pt-2 title-ss text-decoration-none accordion-header\">\n                                        <a role=\"button\" class=\"bg-transparent p-0\" href=\"\">\n                                            <i class=\"fas fa-solid fa-link fa-fw me-2\"><\/i>\n                                            MEDICI\u00d3N IN-SITU DE LA DENSIDAD DE DISLOCACIONES EN METALES BAJO ENSAYOS DE TRACCI\u00d3N Y COMPRESI\u00d3N\n                                        <\/a><\/h3>\n                                    <div id=\"collapse-9364\" class=\"accordion-collapse collapse\" data-bs-parent=\"#9364\">\n                                        <div class=\"accordion-body p-0 pt-4 pb-4\">\n                                            [vc_section el_class=\"container mx-auto align-items-center circle--pattern\" css=\".vc_custom_1648956589196{padding-top: 3rem !important;}\"][vc_row el_class=\"pb-5\"][vc_column][vc_wp_custommenu nav_menu=\"6\"][uoh_breadcrumb_component automatic_breadcrumb=\"true\"][uoh_title_component title_dropdown=\"big\" title_decorator=\"true\"]{{title}}[\/uoh_title_component][vc_column_text css=\"\"]Las dislocaciones son la principal fuente de comportamiento pl\u00e1stico de metales, sin embargo, es muy dif\u00edcil de estudiar cuantitativamente su comportamiento. Con el fin de mejorar esta situaci\u00f3n, se ha propuesto utilizar su interacci\u00f3n con las ondas el\u00e1sticas como una sonda no invasiva. Recientemente, se han demostrado, utilizando espectroscopia de resonancia Ultrasonido (RUS), que un aumento de densidad de dislocaciones en aluminio por un factor de 6 conduce a un cambio de la velocidad de las ondas de cizalle del orden de 1, una cantidad que puede medirse con una precisi\u00f3n del orden de 0,1%.  \r\n\r\nSe propone entonces estudiar la contribuci\u00f3n de las dislocaciones a las propiedades mec\u00e1nicas en dos sistemas de inter\u00e9s: En primer lugar, metales poli-cristalinos, en particular muestras de cobre y de aluminio. En segundo lugar, se propone estudiar muestras con estructura de capas m\u00faltiples, en particular sistemas de capas intercaladas de cobre y de niobio. El objetivo de largo plazo de esta investigaci\u00f3n es permitir el desarrollo de la tecnolog\u00eda de ultrasonido como una herramienta no invasiva para la caracterizaci\u00f3n de materiales.\r\n\r\nSe investigar\u00e1 en primera instancia la contribuci\u00f3n de las dislocaciones a las constantes el\u00e1sticas de metales poli-cristalinos, continuando un estudio anterior. Se realizar\u00e1n nuevas medidas con muestras m\u00e1s puras de aluminio y de cobre, utilizando RUS en primera instancia. Como primer objetivo se plantea obtener un n\u00famero mayor de muestras, con condiciones m\u00e1s extremas que las ya analizadas aumentando el rango de dislocaciones estudiado. Adem\u00e1s de las medidas en el r\u00e9gimen lineal usando RUS, se realizar\u00e1n medidas de par\u00e1metros no-lineales que pueden ser caracterizados a mayores amplitudes de excitaci\u00f3n. Estas medidas pueden ser realizadas con el mismo montaje experimental de RUS. Adem\u00e1s, se propone hacer un an\u00e1lisis ultras\u00f3nico tanto lineal como no lineal en un montaje de deformaci\u00f3n est\u00e1ndar donde las medidas se realizar\u00e1n in situ.\r\n\r\nEn segundo lugar, se propone caracterizar muestras de cobre-niobio, con estructura de capas m\u00faltiples. La motivaci\u00f3n de este tema radica en el hecho que las interfaces del estado s\u00f3lido juegan un papel importante en la determinaci\u00f3n de las propiedades de los materiales compuestos, especialmente de los materiales estructurales destinados para el servicio en aplicaciones de energ\u00eda. En la actualidad, las muestras multi-capas de cobre-niobio pueden ser preparadas en tama\u00f1os \u00fatiles para RUS (desde mil\u00edmetros hasta cent\u00edmetros). Pueden ser fabricas con pocas capas (del orden de 10 capas) y espesores de d\u00e9cimas de mm cada una, o con muchas capas (del orden de 3.10&#8308;) y espesores de 10 nm cada una. La motivaci\u00f3n es obtener mediciones precisas de las constantes el\u00e1sticas efectivas de las muestras mediante hip\u00f3tesis del tipo homogeneizaci\u00f3n, y correlacionar sus valores con la cantidad de interfaces presentes. A primer orden, si dos muestras tienen la misma cantidad de niobio y cobre pero con diferentes n\u00fameros de capas y espesores, el proceso de homogenizaci\u00f3n m\u00e1s simple indica que las propiedades mec\u00e1nicas deben ser iguales. En la pr\u00e1ctica, se espera una contribuci\u00f3n de las interfaces, lo cual no ser\u00e1  despreciable cuando existan una cantidad considerable de ellas. La relaci\u00f3n con las dislocaciones radica en el hecho que estas interfases tienen dislocaciones de tipo misfit, y dependiendo de la orientaci\u00f3n de su vector de Burgers y de su densidad, su contribuci\u00f3n a la elasticidad de la interface ser\u00e1 distinta.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649209804184{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5\"][vc_row el_class=\"container mx-auto align-items-center p-md-0 pt-5\"][vc_column el_class=\"p-0\"][\/vc_column][\/vc_row][\/vc_section][vc_section css=\".vc_custom_1649210787516{background-color: #f6faff !important;}\" el_class=\"p-md-0 pt-md-5 pb-md-5\"][vc_row el_class=\"container mx-auto align-items-center\"][vc_column][\/vc_column][\/vc_row][\/vc_section]\n                                        <\/div>\n                                    <\/div>\n                                <\/div>\n                            <\/div><div class=\"mt-3\"><i class=\"fas fa-solid fa-user-tag fa-fw me-2\"><\/i><small class=\"text-muted\">Investigador\/a Responsable<\/small><\/div><span class=\"caption-field-publish\"><\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>[\/vc_tta_section][vc_tta_section title=&#8221;Libros y Monografias&#8221; tab_id=&#8221;libros&#8221;]<link rel=\"stylesheet\" id=\"font-awesome-css\" href=\"https:\/\/cdnjs.cloudflare.com\/ajax\/libs\/font-awesome\/6.5.1\/css\/all.min.css\" type=\"text\/css\" media=\"all\"><div class=\"row m-0 p-0\"><div class=\"col-12 col-md-9 pt-5 pt-md-0 px-md-0 \"><\/div><\/div>[\/vc_tta_section][vc_tta_section title=&#8221;Contacto&#8221; tab_id=&#8221;contacto&#8221;][\/vc_tta_section][\/vc_tta_tabs][\/vc_column][\/vc_row][\/vc_section]<\/p>\n<\/div>","protected":false},"featured_media":7763,"template":"","institute_academics":[3],"profile_academics":[2],"class_list":["post-6565","academics","type-academics","status-publish","has-post-thumbnail","hentry","institute_academics-instituto-de-ciencias-de-la-ingenieria","profile_academics-academico"],"rut_academico":"15604408-3","mail_academico":"vicente.salinas@uoh.cl","n_proyectos":"9","n_publicaciones":"18","n_libros":"5","n_cap_libros":"0","n_otros_libros":"0","acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 -
