- Nutritional and functional characterization of mexican medicinal plants : Ludwigia octovalvis, Cnidoscolus aconitifolius, and Crotalaria longirostrata, with implications for food system integration and glycemic response reduction(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2025-11-30) Ramos Calónico, Kimberly Andrea; Rosa Millán, Julián de la; Vázquez Lepe, Elisa Virginia; mtyahinojosa; Ramírez Jiménez, Aurea Karina; Cardador Martínez, Ma. Anaberta; Luna Vital, Diego Armando; Ovando Martínez, Maribel; Santos Zea, Liliana; School of Engineering and Sciences; Campus MonterreyThis dissertation investigates the potential of three underutilized Mexican medicinal plants—Ludwigia octovalvis (Jacq.) P.H. Raven, Cnidoscolus aconitifolius, and Crotalaria longirostrata—to improve the nutritional quality, physicochemical properties, and predicted glycemic response of wheat-based bread. The research integrates biochemical, structural, and technological evaluations across three peer-reviewed studies. The first stage characterizes the chemical composition, phenolic profile, and in vitro inhibitory activity of the plants against key digestive enzymes (α-amylase, α-glucosidase, lipase, and pepsin), establishing their metabolic relevance and bioactive potential. The second stage evaluates the incorporation of plant flours into wheat dough (5% w/w), examining gluten functionality, dough rheology, phenolic–protein interactions, and microstructural modifications during fermentation. The third stage assesses the nutritional composition, dietary fiber fractions, starch digestibility (RDS, SDS, RS), and predicted glycemic index (pGI) of breads enriched with C. aconitifolius and C. longirostrata, using standardized in vitro digestion protocols. Collectively, the findings demonstrate that these medicinal plants modulate dough development, influence starch digestion kinetics, and can effectively reduce the pGI of bread through combined mechanisms of enzymatic inhibition and matrix driven structural modifications. This work provides a mechanistic and formulation based foundation for the development of functional foods derived from ethnobotanically relevant Mexican species, contributing to dietary strategies aimed at reducing postprandial glycemic responses.
- DC-DC high-order converters for renewable applications(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-05-07) Garza Arias, Enrique; Valdez Resendiz, Jesús Elias; Rosas Caro, Julio César; Escobar Valderrama, Gerardo; Castañeda Cuevas, Herman; Escuela de Ingeniería y Ciencias; Campus Monterrey; Guillén Aparicio, DanielThis dissertation develops new theory and techniques for DC-DC power converters interfacing renewable energies, specifically for converters classified as high-order based on their mathematical model, and thus generally more complex and difficult to analyze. The thesis encompasses the development of a new circuit topology, a control design focused on high-order dynamic systems, and the study of conversion systems between renewables and the utility grid. The dynamics of high-order converters present challenges for the stability and synthesis of controllers. By studying the nonlinear model of fourth-order non-minimum phase converters through zero dynamics, it has been established that some of these can attain stability under direct voltage at high regulation, in contrast to second-order converters. Controllers have been designed to take advantage of these results in order to remove the current sensing stage while still achieving high bandwidth voltage regulation. Research has also been conducted into creating novel DC converters with a lower component size than similar circuits. From this, an improved super-boost converter has been developed that requires lower energy storage on its capacitors and inductors than the traditional boost and fourth-order boost converters, for a given specification of input current and output voltage ripples. Additionally, an inverter system for a fuel cell stack has been developed using double-dual converters in cascade to increase the voltage gain and power handling of the system. Results from tests at different power and voltage levels show that the proposed system also achieves reduced switch voltage stresses and reduced output current ripples. Simulation and experimental results were obtained in order to validate the theoretical analysis. Mathematical models, steady state values and stability conditions were calculated, and prototype designs were developed to corroborate the performance of the converters, control and efficiency.

- Enhancing physical properties of aluminum 6061 by electrodeposition of multi-walled carbon nanotubes(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-02-08) Rodríguez Salinas, Juan José; RODRIGUEZ SALINAS, JUAN JOSE; 37308; Elias Zuñiga, Alex; qro /|bqrotbecerra; Cardenas Aleman, Eduardo; Olvera Trejo, Daniel; Palacios, Luis Manuel; School of Engineering and Sciences; Campus Monterrey; Martinez Romero, OscarThe development of a new generation of material has been of great interest in the ever-demanding industrial applications. This new generation of materials is required to be lighter, economical, and machinable with increased mechanical, electrical, thermal, and tribological properties. This work proposes the use of Nanotechnology as a development tool to overcome these demands. This work proposed the use of carbon nanotubes as the medium to enhance the electrical and thermal properties of the aluminum by the deposition of a nano coating of carbon nanotubes over the surface of the aluminum by an electrochemical process that modify the surface of the aluminum creating a thin film that enhances its physical properties. The samples produced by electrodeposition show an increment in electrical, thermal, and tribological properties. This results produced a new generation of nano-enhanced commercial aluminum that could be used for electrical applications. Finally, these results guide the first steps towards a scale-up EDP for industrial applications.
