En esta tesis se sintetiza y caracteriza un nuevo polímero basado en el biimidazol, el poli[4-4'(p-fenilen)-2,2'bi-1H-imidazol] (PBII), con el objetivo de evaluar su viabilidad como polímero conductor en membranas de pilas ...
Franco García, Ma. Lourdes (María Lourdes) (Date of defense: 1994-10-14)
Se han sintetizado nylons 1,n (n=5,6,7,8,10 y 12); nylons 2/n estadísticos con distintas proporciones de glicina (n=6, 11 y 12) y nylons m,n (m=6,12; n=6) con glicina incorporada secuencialmente y al azar. Los productos ...
Martínez Palau, Meritxell (Date of defense: 2008-04-16)
La creciente demanda de materiales biodegradables para su utilización en el campo de la biomedicina ha incrementado el interés en la síntesis de nuevos polímeros. Los poliésteres alifáticos constituyen el grupo de polímeros ...
Lopes Rodrigues, Maximilien (Date of defense: 2019-11-11)
This thesis focuses on the preparation of nanomaterials made of proteins and polymers. Even though the technology has advanced in the last decades to design new devices at the atomic scale, researchers are still inspired ...
Herrera Hernández, María Guadalupe (Date of defense: 2017-03-24)
Dietary polyphenols represent a group of secondary metabolites which widely occur in fruits, vegetables, wine, tea, extra virgin olive oil, chocolate and other cocoa products. Previous studies have shown the interaction ...
Millán Elías, Cinthia Raquel (Date of defense: 2017-10-27)
AT-rich sequences confer unique properties to DNA, such as high polymorphism and flexibility. The abundance of AT-rich DNA in several pathogens' genomes and the ability of specific molecules to selectively target AT base ...
Acosta Reyes, Francisco Javier (Date of defense: 2016-05-26)
Non-coding DNA is rich in adenines and thymines. Their unique properties, such as high polymorphism, flexibility, transitional states that lead to DNA hairpin formation and the possibility to adopt either Watson-Crick or ...
Rodríguez Contreras, Alejandra (Date of defense: 2013-06-06)
Nowadays biopolymers are a good alternative to petrochemical polymers. One of these biopolymers is Poly[(R)-3- Hydroxybutyrate] (PHB) which is produced from renewable resources by various microorganisms and, after its use ...
Casas Carné, María del Pilar (Date of defense: 2010-03-25)
Cotxes, camions, tractors, avions... tots necessiten els neumàtics com a component imprescindible per al seu funcionament. Malauradament, degut al desgast per ús, els neumàtics tenen una vida útil limitada que obliga a ...
