(WILEY-V C H VERLAG GMBH, 2006-08-07)Functionalized metallocene copolymers synthesized from ethylene with 5-hexen-1-ol and ethylene with 10-undecen-1-ol were used as compatibilizers in LDPE/starch and LDPE/dextran blends in order to improve the interfacial ...
-
(Mary Ann Liebert, 2009)All engineered bioartificial structures developed for tissue regeneration require oxygen and nutrients to establish proper physiological functions. Aiming to improve vascularization during dermal regeneration, we combined ...
-
(2010)Pretreatment of lignocellulosic materials is an important step to achieve higher amounts of simple sugars, mono- and disaccharides, for obtaining ethanol as a biofuel, via enzymatic hydrolysis. The study introduces a concept ...
