Abstract: Solar heating and cooling technologies can be crucial in realizing energy security and economic development targets and mitigating climate change. Solar heating and cooling technologies have specific benefits; they are compatible with nearly all sources of backup heat and are almost universally applicable due to their ability to deliver hot water, hot air, and cold air. For this reason, we aim to optimize concentrated solar trigeneration systems using customized nanofluids and concretes for heat transfer and storage thermal with enhanced solar radiation absorption and thermal conductivity properties; likewise, we combine the characterization of the nanofluid synthesis and concretes with multiscale numerical models covering nanofluid microstructure, concretes to a macroscopic description of the trigeneration system. We combine theoretical predictions with experiments in specific test rigs that mimic nanofluid and concrete operation in natural conditions and nanofluid and concrete characterization under controlled tests. Therefore, we research solar-driven technologies to replace either fossil fuels or electricity used for heat production (e.g., for industrial processes, heating, etc.); the solar thermal cooling technology can also reduce electric grid loads at times of peak cooling demand due to the strong correlation between supply of the solar resource and energy demand for cooling.

Abstract: Within the framework of my participation in the Materials Science, Engineering, and Nanotechnology Researchers Network, I am presenting my research interest as the Analysis of the mechanical behavior and oxidation resistance of thermal barrier coatings exposed to oxidation at high temperatures to improve performance in applications. with extreme environments such as the aeronautical sector. This is based on my experience with processing, characterization, densification, mechanical behavior, and oxidation studies of ceramic coatings manufactured mainly by atmospheric plasma thermospray. Thermal barrier coatings are a highly advanced technology applied to metal surfaces in gas turbines operating at elevated temperatures. These coatings can allow for higher operating temperatures and limit thermal exposure of structural components, thereby extending part life. However, thermal barrier coating failures can occur in many ways depending on the combination of materials and techniques used to manufacture the thermal barrier coating system and the service conditions. In recent years, the durability of thermal barrier coatings has provided the driving force and motivation for research and development. My particular interest is understanding the underlying degradation and failure mechanisms of thermal barrier coatings used for gas turbines at higher operating temperatures to further evaluate and improve the durability and reliability of thermal barrier coatings.

Abstract: Asset management and maintenance are fundamental pillars for the success and sustainability of small and medium-sized enterprises. In this context, implementing effective maintenance strategies can significantly improve operational efficiency and asset longevity. Small and medium-sized enterprises, often constrained by resources, can greatly benefit from preventive and predictive maintenance practices that minimize downtime and operational costs. Maintenance in non-industrial spaces, such as commercial buildings, educational facilities, and residential complexes, presents unique challenges. Unlike industrial environments, these spaces require asset management that prioritizes user comfort and safety while maximizing energy efficiency and minimizing environmental impact. Adopting smart technologies for monitoring and maintaining HVAC systems, lighting, and security is essential to ensure the optimal functioning of these facilities. The Industry 4.0 revolution has transformed the approach to maintenance, introducing advanced technologies such as the Internet of Things, artificial intelligence, and data analytics. These tools enable real-time monitoring and predictive maintenance, anticipating failures before they occur and optimizing resource use. Adopting these technologies can be a differentiating factor for small and medium-sized enterprises, allowing them to compete in an increasingly digitalized and efficient market. Finally, asset management and sustainable systems are intrinsically linked. Sustainability in asset management involves energy efficiency and emission reduction and adopting practices that extend asset lifespan and reduce waste. This translates into a holistic approach that integrates the entire asset lifecycle, from acquisition to disposal, promoting environmental responsibility and economic efficiency. In summary, asset management and maintenance in small and medium-sized enterprises, non-industrial spaces, Industry 4.0, and sustainability require an integrated approach that leverages advanced technologies and promotes sustainable practices to ensure long-term success.

Abstract: Using emerging technologies for risk management in agricultural production processes improves the production of strategic crops. Through the characterization of events and technologies applied to these crops, the most appropriate technologies for their monitoring and management are identified through a detailed analysis of common events. From this characterization, a hardware architecture composed of sensors and monitoring stations optimized for collecting relevant data in real-time is designed. Subsequently, artificial intelligence models are implemented to identify risk patterns in the collected data. These models, based on advanced deep learning techniques to detect anomalies and foresee possible incidences of pests and abiotic agents, improve the capacity to respond to adverse crop events. The developed models are integrated within a framework that combines data processing capabilities at the edge with advanced analytics in the cloud, providing a robust and scalable solution. This developed framework can be adapted for application in new crops and other production processes of interest. The partial and expected results show the feasibility and benefits of implementing emerging technologies in agricultural risk management, proposing an innovative model that can be replicated in other agricultural scenarios and contribute to the efficiency and sustainability of agricultural production processes.

Abstract: Dielectric barrier discharges have an increasing number of technological applications every day, not only because of the ease of their control but also because of the wide range of pressures at which they can be operated, including at atmospheric pressure. The devices to operate dielectric barrier discharges are easy to acquire and cheap; with dielectric barrier discharges, surface treatments of different materials can be performed, from deposition to ion implantation. Likewise, it can be used for stripping or cleaning surfaces. Among the most widely used applications is ozone generation for water treatment. Among the studies carried out by researchers is the effect of the surface roughness of the substrates on surface treatment processes, specifically on the nitriding of carbon steels. It has been found that depending on the type of finish or roughness of the samples to be treated, there is greater homogeneity of the profiles in the case of ion implantation and better adhesion in the case of deposits. Furthermore, nitriding improves the corrosion resistance of carbon steels and increases the hardness of the surfaces, i.e. improves the tribological properties of these materials.

Abstract: Advances in nano-fabrication technologies in recent years have allowed intensive research into nano-structured superconductors. It is well known that, for very confined systems, the thermodynamic critical fields increase extraordinarily. Most superconducting applications require control of the density and/or motion of the vortices. A very efficient way to achieve this is by creating mesoscopic vortex traps, which can be done experimentally using nano-lithography techniques. One way to change or improve the properties of superconducting samples is by controlling the boundary conditions of the sample, theoretically we can simulate different types of materials surrounding the sample by varying the boundary conditions for the order parameter. In other areas of study, we can analyze energy levels in semi-conducting systems and Bose-Einstein condensates, vortices in galaxies, and in any area of science and engineering where there is a theoretical model in which it can be simulated using numerical methods. The key issue is that the magnetic field, the electric current and the boundary conditions of the sample, by theoretically simulating the different systems, we can provide and predict experimental results at low cost, where they play a very important role in the thermodynamic properties of the material.

Abstract: The Atomic and Molecular Spectroscopy Laboratory has a variety of equipment that allows the characterization of materials in liquid and solid phases. The first technique is inductively coupled plasma atomic emission spectroscopy, an elemental analysis technique that allows the establishment of the composition of a sample or the presence of contaminants at the trace level, parts per million, and, in some cases, parts per billion. Other techniques are vibrational in nature and allow the identification of present functional groups. Fourier transforms infrared spectroscopy with extended range (400 cm-1 - 12000 cm-1) with different variants: transmission, fully attenuated reflectance single pass (diamond crystal), multipass with variable angle, diffuse reflectance, and photoacoustics. Raman spectroscopy, two confocal microscopes with a working range of 50 cm-1 - 4000 cm-1, 10X, 50X, 100X objectives, and 1cm-1 resolution are available; being confocal, it allows the construction of chemical images of a sample with a lateral resolution of 0.2 μm. Other techniques that are in daily use are UV-Vis absorption spectroscopy, with an integrating sphere, spectrofluorometer with a range (of 200 nm - 1600 nm) and availability to work with liquid and solid samples; dynamic light scattering with a range of 5 nm - 3 μm, fluorescence microscope with a camera and four cubes to select wavelength ranges. Additionally, other laboratories at the university have techniques such as X-ray photoelectron spectroscopy, X-ray diffraction, and scanning electron microscope.

Abstract: The university functions considered substantive for the University of the Republic of Uruguay are divided into teaching, research, and extension. Thus, our performance as teachers and researchers goes through these three pillars. In this presentation, I collect the main lines of action I work at the Udelar, which can contribute to the Materials Science, Engineering, and Nanotechnology Researchers Network. In terms of research, two large areas of action stand out: one that corresponds to new methodologies of teaching and learning of sciences, with a focus on the formation of interdisciplinary teams for the resolution of complex problems that society demands, and a second area of work that involves the study of natural materials, which can be an inspiration for the development of new materials, mainly through surface modification at the micro and nanoscale. These modifications provide new physicochemical properties to the material, such as superhydrophobicity, electrical conductivity, and optics, among others. Regarding education, the work is at the undergraduate and graduate levels on applying new teaching methodologies to better understand the phenomena linked to basic and natural sciences. Likewise, university, primary, and secondary school teachers are trained to apply these methodologies in their classrooms. Finally, in extension, the work is on mentoring at Science Club fairs, scientific dissemination through the academic coordination of a postgraduate degree in Science and Technology Communication, collaboration with science museums in the development of nanoscience and nanotechnology experiences and in the design of scientific activities to be carried out in schools and high schools.
