(Universidad EAFIT, 2020) Isaza Álvarez, Juan Camilo; Cortez Reinoso, Cristian Alexis; Gonzales, Juan Pablo; Martinod, Thomas; Escobar Patiño, Alma; Salcedo, Jefferson Daniel; Cardona, Juan David; Marulanda Bernal, José Ignacio; Universidad EAFIT
With this project, the use of the long-range ground station (500 km), located at the EAFIT Llanogrande headquarters, for agronomic and social applications was proposed. This station is in the start-up phase with the 2019 Applied Electromagnetism Seedbed (SEMA) project underway. Taking advantage of the payload capacity of an unmanned aerial vehicle (UAV) and the transmission range capacity of the base, activities in the agricultural sector can be carried out such as irrigation, fumigation and crop sensing among other applications, in addition to its possible use in humanitarian aid by having greater access through UAVs to places that cannot be easily accessed to transport objects and aid. Additionally, the proposal could very well be included as a topic of study in the recent undergraduate degree in agronomic engineering created at the University.

The project evaluated a method to generate energy from the electromagnetic field around an alternating current line. Different toroidal geometries were explored to obtain relationships between the current circulating through the line and that induced in the toroids and thus consider the possibility of using this procedure as an “energy Harvesting” method.
Proceso de ASC - ESTUDIO CONCEPTUAL DE LA GASIFICACION POR PLASMA PARA LA PRODUCCION DE SYNGAS
(Universidad EAFIT, 2023) Palacio Espinosa, Claudia Constanza; Aguiar Castrillón, Juan Sebastián; Morales Paternina, Samuel David; Peña Arango, Karol Andrea; Arboleda Londoño, Juan Manuel; Universidad EAFIT
Gasification is a thermochemical process through which waste materials, such as biomass, are transformed into synthesis gas (SYNGAS) to produce fuel gas that can be used as an energy vector. Energy generation from biomass typically involves combustible agents like wood, coal, and refined petroleum products, which are used for their ability to convert mass into thermal energy, which can then be transformed into mechanical work and even electrical energy. Plasma, or ionized gas, has various properties depending on its nature and can be either cold or hot plasma. Hot plasma can reach extremely high temperatures, even higher than those in combustion processes, enabling the transformation of both organic and inorganic matter by reaching their melting points. Thus, plasma is a valuable tool for gasification processes, converting matter (organic and inorganic) into synthesis gas. Additionally, the implementation of gasification processes seeks to benefit the environment through solid waste treatment, production of low or zero carbon footprint fuels, and sustainable energy. Consequently, knowledge about the use of high-temperature plasmas for solid waste treatment is of great scientific interest to the materials research group, due to its significant environmental and social impact.
Proceso de ASC - ESTUDIO DE MATERIALES CERAMICOS PARA APLICACIONES MEDICAS FASE 2
(Universidad EAFIT, 2019) Palacio Espinosa, Claudia Constanza; Rendón, José Manuel; Hernández, María Camila; Restrepo, Vanessa; Machado, Santiago; Rodriguez, Valentina; Gil, María José; Universidad EAFIT
The rapid population growth in recent years has significantly increased the demand for implants, which have traditionally been developed from metallic materials. However, due to the inherent disadvantages of these materials, ceramic implants have been developed, creating a market worth approximately 253 billion dollars annually. Ceramic materials possess several key characteristics that make them suitable for implants, such as biocompatibility, osteoconductivity, easy adhesion, porosity, neutral pH, and excellent mechanical properties. In the Colombian context, there is a noticeable lack of contributions in the field of implants, particularly ceramic ones. This gap presents an opportunity to conduct research that can bring new ideas, propose innovative formulations to tackle new challenges, improve existing implants, and much more, all with the goal of making significant advances in this important global issue. For these reasons, after conducting a technology assesment in the SCOPUS database and engaging in several discussions with experts on the topic, it was observed that Portland cement, commonly used in construction, is an alternative that has not been widely studied.. Thus, it was decided to investigate whether this material is indeed suitable for medical applications. This required studying all the processes needed for Portland cement to meet the mechanical and biological characteristics that would make it a biocompatible material. In essence, the goal of this project is to determine whether Portland cement can be used as a ceramic implant, evaluate its advantages and disadvantages compared to other materials used so far, and explore how to enhance its performance.
Proceso de ASC - ESTUDIO DE MATERIALES CON MEMORIA DE FORMA EN LA CONSTRUCCION DE MUSCULOS ARTIFICIALES
(Universidad EAFIT, 2021) Palacio Espinosa, Claudia Constanza; Herrera Pino, Adrián; Chica Quintero, Jacobo; Cardona, Yoshiro Yi; Universidad EAFIT
Materials have different properties that distinguish them from one another, some of which are used to our advantage in the development of new technologies that enable day-to-day advancements. In this project, the properties of certain materials were studied to allow the design and construction of artificial muscles. These materials are those that exhibit the SME (Shape Memory Effect), particularly shape memory polymers. Throughout the project, relevant research was conducted on the existing theory, the fundamental physical and chemical phenomena of the problem, and the creation of shape memory polymers that enable the development of artificial muscles.
Proceso de ASC - ESTUDIO DEL CICLO DE VIDA Y DISPOSICION FINAL DE BATERIAS DE VEHICULOS ELECTRICOS-FASE EXPLORATORIA
(Universidad EAFIT, 2020) Palacio Espinosa, Claudia Constanza; Rodríguez, Valentina; Gil, María José; Rendón, José Manuel; Machado, José Manuel; Hernández, Edxaidys; Restrepo, Vanessa; Herrera, Adrián; Otálvaro, Felipe; Universidad EAFIT
The high levels of air pollution that have been documented in recent years in the country's main urban areas, consistent with global patterns, have prompted national authorities to consider tax incentives for mobility options that encourage environmentally friendly practices. These measures are designed to not only mitigate existing air pollution but also promote sustainability. As a result, there has been a significant increase in the purchase of electric vehicles. According to Andemos Colombia, as of January 31, 2019, there are 2,826 electric cars and motorcycles in Colombia, including 1,048 cars and 1,778 motorcycles, which is just 0.02% of the total 14,104,129 vehicles in the national fleet. However, some concerns focus on the future, as without proper planning, one problem could be replaced by another, or even worsen. Batteries, which are essentially chemical systems for energy production, are made of materials that can be difficult to recycle without the proper disposal processes, potentially leading to significant soil and water pollution in the future. This concern has raised questions such as: What will be done with the batteries from electric vehicles when they need replacement? How will they be recycled? What processes are necessary for the environmentally responsible disposal of these batteries? Therefore, the materials research group aimed to investigate the composition of these batteries more deeply and explore recycling methods to prevent further environmental damage.
