Sphingolipids (SLs) encompass a large and diverse family of lipids that are essential constituents of cellular membranes. In addition to their structural functions, SLs are also emerging as important signalling molecules ...
La Tesi tracta sobre la preparació i l’ús en catàlisi homogènia asimètrica de lligands fosforats quirals amb àtoms de fòsfor estereogènics. En primer lloc es descriu la preparació i caracterització de lligands monofosforats ...
Carbohydrates are one of the most important biochemical molecules due to their role as energetic resource for non-photosynthetic organisms, cell-cell recognition and adhesion, protection of cell membranes of bacteria and ...
Posar al mercat un nou fàrmac és un procés molt llarg i costós i que comporta un risc econòmic important per una empresa farmacèutica. En canvi, el desenvolupament d'un procediment millorat per a la producció d'un fàrmac ...
One of the main objectives of this thesis was the synthesis of new chelating ligands containing a photochromic unit able to change its conformation upon light irradiation. This isomerization should serve to modify the ...
Hace unos años, en el grupo de investigación donde se ha realizado esta Tesis Doctoral, se estudió un sistema de oro(I)-alquinilo con una fosfina soluble en agua, que dio lugar a la formación de un hidrogel. Este ejemplo ...
[eng] This thesis explores the design and synthesis of molecular heterometallic lanthanide coordination compounds, highlighting their potential applications in quantum computing, as light-emitting devices, and for magnetic ...
In this doctoral thesis a series of computational and experimental studies of molecular magnetoresistance devices at room temperature is presented. This sort of devices is included in the molecular electronics framework ...
An alternative allowing diene-derivatised polyamides to be used in Diels-Alder conjugation reactions has been explored and developed. In this methodology, conjugation takes place between a fully protected, resin-linked ...
En el present treball s’han sintetitzat dos lligands divalents i tres lligands monovalents per a les proteïnes avidina i estreptavidina, i s’han determinat les corresponents constants d’associació. Els lligands divalents ...
Se han sintetizado nanopartículas (NPs) de paladio depositadas en la superficie de nanopartículas de magnetita (MNPs) previamente modificadas con el nuevo ligando 4- mercaptofenildifenilfosfina (Sdp). Estos híbridos mostraron ...
[eng] Nanostructured semiconductors have gained significant importance due to their size- and morphology-tunable physical properties, and their ability to play a critical role in various fields such as energy conversion ...
