PCL/POSS Nanocomposites: Effect of POSS Derivative and Preparation Method on Morphology and Properties
(MDPI, 2018-12-26)
The incorporation of polyhedral oligomeric silsesquioxanes (POSS) molecules as nanoparticles into polymers can provide improved physico-chemical properties. The enhancement depends on the extent of dispersion of the ...
Radiopaque Material for 3D Printing Scaffolds
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2018)
The so called “Additive manufacturing” is a new manufacturing process which consists in translating virtual solid model data into physical models in a quick and easy process. The most known example is 3D printing. In the ...
Biodegradable Polyester / Crystalline Nanocellulose Nanocomposites for Biomedical Applications: Preparation and Characterization
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2018)
The use of biodegradable polymers in biomedicine is rising and polymer matrices loaded with reinforcements can be good candidates for temporary implants and tissue engineering scaffolds. In this work poly (ethylene brassylate) ...
Biodegradable Polycarbonate Iongels for Electrophysiology Measurements
(MDPI, 2018-09)
In recent years, gels based on ionic liquids incorporated into polymer matrices, namely iongels, have emerged as long-term contact media for cutaneous electrophysiology. Iongels possess high ionic conductivity and negligible ...
Catechol End-Functionalized Polylactide by Organocatalyzed Ring-Opening Polymerization
(MDPI, 2018-02-06)
There is a great interest in incorporating catechol moieties into polymers in a controlled manner due to their interesting properties, such as the promotion of adhesion, redox activity or bioactivity. One possibility is ...
Unexpected Synthesis of Segmented Poly(hydroxyurea−urethane)s from Dicyclic Carbonates and Diamines by Organocatalysis
(ACS, 2018-07-17)
A complete study of the effect of different organocatalysts on the step-growth polyaddition of a five-membered
dicyclic carbonate, namely diglycerol dicarbonate, with a poly(ethylene glycol)-based diamine in bulk at 120 ...
Three-Dimensional Conductive Scaffolds as Neural Prostheses Based on Carbon Nanotubes and Polypyrrole
(ACS Publications, 2018-12-19)
Three-dimensional scaffolds for cellular organization need to enjoy a series of specific properties. On the one hand, the morphology, shape and porosity are critical parameters and eventually related with the mechanical ...
Tuning the Affinity of Catechols and Salicylic Acids towards Al(III): Characterization of Al-Chelator Interactions
(2018-06-11)
Due to aluminum's controversial role in neurotoxicity, the goal of chelation therapy, the removal of the toxic metal ion or attenuation of its toxicity by transforming it into less toxic compounds, has attracted considerable ...
Miscibility and degradation of polymer blends based on biodegradable poly(butylene adipate-co-terephthalate)
(Elsevier, 2018-02-21)
The aim of this work is to analyse the effect of the preparation method on the miscibility of poly(butylene adipate-co-terephthalate) (PBAT) and poly(hydroxy ether of bisphenol A) (PH) blends and to provide a better ...
Influence of the rigid amorphous fraction and crystallinity on polylactides transport properties
(ACS, 2018-05-15)
The effect of the crystallinity and polymorphism of PLLA and PDLA-PLLA 50:50 blends on the free volume and transport properties have been studied. In the case of PDLA-PLLA 50:50 the increase on crystallinity promotes a ...
