Fil: Cottet, Celeste. Universidad Nacional de Quilmes; Argentina. Actualmente, ante la creciente preocupación por el impacto ambiental generado por los materiales de origen petroquímico, existe la necesidad de obtener ...

Ring-opening homo- and co-polymerization reactions of ε-caprolactone were performed by employing anionic polymerization (high vacuum techniques) and lithium silanolates (LS) as initiators. LS were obtained by reaction b...

Abstract Photoinitiated polymerization of methyl methacrylate has been observed using cw-CO2 laser radiation of (10.6 µm). Both of DSC and TGA thermal analysis techniques were used for identification of the thermal char...

he bond strength between lithium disilicate veneers and tooth structure depends on factors such as curing technique and luting agent. Preheated composite resins have been proposed as alternative luting agents due to thei...

A conventional SAXS study of ordered phases produced in cured block copolymer (BCP)/epoxy blends with different concentrations, led to the unexpected observation of an HPC (hexagonally-packed cylinders) phase for a blend...

Micoleakage comparison of bulk-fillcomposite beetwen oblique incremental and bulk placement techniques. Resin composite bulk-fill was a new type of resin composite that speed up application process of composite. The conc...

This work presents the synthesis of ternary composites at laboratory and bench scale. A possible industrial scale-up was also evaluated. The synthesis of polyaniline on nickel oxide–carbon black (NiO-CB) was carried ou...

Polymerization of caprolactone using lipases from Candida antarctica B, Rhizomucor meihei, Candida rugosa, and Pseudomonas fluorescens is highly effective, with 97% conversion into polycaprolactone. Poly(propylene)-suppo...

An empirical method for determining the crystallinity of native cellulose was studied with an x-ray diffractometer using the focusing and transmission techniques. The influence of fluctuations in the primary radiation an...

"El objetivo general de esta tesis es investigar aspectos aún no dilucidados en el área de la ingeniería del proceso de polimerización en masa de estireno (St) en presencia de elastómeros para la producción de Poli...
