Synthesis of Water-Dispersible Isocyanate-Free Poly(hydroxyurethane)s from 5- and 8-Membered Cyclic Carbonates Using the Acetone Process
(2020-10-16)
[EN]Water-dispersible isocyanate-free poly(hidroxyurethane)s (PHU)s dispersions were made from amino-terminated poly(dimethylsiloxane), renewable diglycerol dicarbonate (DGC) and 8-membered cyclic carbonate ((bis) N-8-C) ...
Organic-inorganic hybrid thermoelectric materials by a concept of simultaneous vapor phase infiltration (VPI/SCIP) of polymers by Bi2S3
(2022-10-18)
Este trabajo tiene como objetivo diseñar nuevos materiales termoeléctricos (TE) híbridos mediante infiltración en fase vapor (VPI). El origen del VPI reside en la técnica de deposición de capas atómicas o ALD y se basa en ...
Polymers for the preparation of heterogeneous catalysts
(2021-11-23)
In this work it has been studied the effect different polymers (or also the same polymer with different properties) can make in the preparation of catalysts Ni-La/Al2O3 by the wet impregnation with excess of water. In order ...
Photoinduced raft polymerization from novel water-soluble single-chain nanoreactors
(2022-10-18)
Single chain nanoparticles (SCNPs) are ultra-small size nano-objects, which are obtained by the collapse of a single polymer chain. In the literature, there are many examples of potential SCNPs for a range of applications ...
Synthesis and characterization of side-chain cholesterol based linear liquid crystal polyurethanes
(2020-10-16)
[EN]Liquid crystal polymers (LCPs) are currently one of the most studied polymeric materials developed for new optical and photonic technology. The exclusive properties displayed by LCPs initiated a new research trend in ...
Effect of different compatibilizers on the final properties of the PLA/PBSA biopolymers-based blend prepared by reactive extrusion
(2023-10-09)
It is well known that the research for biopolymers-based materials is crucial in these times where the environmental issues resulting from the plastic industry keep increasing. Poly Lactic Acid (PLA), a biodegradable and ...
Development of nanomaterials to overcome the mucosal barrier modulating their mucoadhesion and mucopenetration properties
(2023-10-09)
The aim of this work is to synthesize and develop polymeric nanoparticles (NP)
that are able to interact with mucosal tissue for potential drug delivery. It is
hypothesized that the NPs will be successfully functionalized ...
Chiral Diamine Derivatives: Synthesis and Evaluation as Transient Directing Groups (TDGs) in C(sp3)-H activation reactions of α-keto amides
(2023-10-09)
This research project has been developed in the Department of Organic Chemistry I at the Faculty of Chemistry in Donostia, under the guidance of Professor Maria Antonia Mielgo Vicente. Research carried out in this project ...
Computational study of aromaticity with electron delocalization indices
(2023-10-09)
In this undergraduate thesis, a computational study on aromaticity has been conducted. The calculation of various aromaticity indices for different molecules was performed, with a particular focus on analyzing the behavior ...
