Kinetic study of polydopamine sphere synthesis using TRIS: relationship between synthesis conditions and final properties.

The synthesis and characterization of polydopamine (PDA) using dopamine (DA) as the monomer and (hydroxymethyl)aminomethane (TRIS) as the oxidant is studied. The effect of temperature and TRIS concentration on the kinetics of dopamine polymerization is evaluated, and the kinetic parameters are also calculated. Three TRIS concentrations are used to assess their effect on DA polymerization kinetics.

Effect of microwave polymerization on the thermomechanical and surface properties of ocular prosthetic acrylic resins.

Background: Polymerization conditions affect the physical-mechanical properties of acrylic resins used for craniofacial prostheses.

Objective: The aim of this study was to evaluate the effect of microwave polymerization on the thermomechanical properties and surface morphology of ocular prostheses fabricated with polymethyl methacrylate (PMMA).

Methods: PMMA discs were polymerized with microwave energy and with conventional heat polymerization (CHP) method.

Synthesis of a PVA drug delivery system for controlled release of a Tramadol-Dexketoprofen combination.

The local administration of analgesic combinations by means of degradable polymeric drug delivery systems is an alternative for the management of postoperative pain. We formulated a Tramadol-Dexketoprofen combination (TDC) loaded in poly(vinyl alcohol) (PVA) film. Films were prepared by the solvent casting method using three different molecular weights of PVA and crosslinking those films with citric acid, with the objective of controlling the drug release rate, which was evaluated by UV-vis spectrometry.

RGD-functionalization of PLA/starch scaffolds obtained by electrospinning and evaluated in vitro for potential bone regeneration.

The engineering of bone tissues represents an area of opportunity for the development of new polymeric compounds. In this context, the objective of this work is the generation and evaluation in vitro of supports obtained from mixtures of starch with poly (lactic acid) (PLA), treated with arginine-glycine-aspartic acid peptides (RGD). For this, non-woven fibers of PLA with different starch content (0.

Experimental data in support of characterization of the CePO dispersion into transparent PMMA/PU IPNs by the sequential route.

This article is focused on the complementary data referring to the article "Dispersion of upconverting nanostructures of CePO using rod and semi-spherical morphologies into transparent PMMA/PU IPNs by the sequential route". It contains the XPS data of CePO photographs and DSC thermograms of transparent PMMA/PU IPNs as well as with CePO dispersed in different wt.%, Confocal laser scanning micrographs, transmission electron microscopy (TEM), optical images of surface, and visual inspection (photographs) before and after aging of hybrid materials.
