Searching for suitable catalysts for a passive direct methanol fuel cell cathode
(Elsevier, 2015)Trimetallic PtMRu/C cathode catalysts with M ¼ Co or Fe obtained by an impregnation procedure using ethylene glycol and NaBH4 as reducing agent, with suitable activity for the oxygen reduction reaction (ORR) and improved ... -
Siloxanes synthesized in situ by solgel process for fire control in wood of Araucaria angustifolia
(Elsevier, 2013-10-10)Panels of Araucaria angustifolia were chemically modified with alkoxysilanes, hydrolyzed and condensed “in situ” by the sol–gel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane (A), aminopropyl ... -
Síntesis de nano catalizadores para celdas de combustible de metanol directo
(Revista Tecnología y Ciencia UTN, 2014)Las celdas de combustible de metano/ directo, DMFCs, permiten una conversión completa de la energía de la reacción química (CH)3OH(ac)+3/2 O2(g)=7CO2(g)+2H2O(l) en energía eléctrica. El platino es el catalizador más utilizado ... -
Starch Polyvinyl Alcohol blends containing Polyurethane as plasticizer
(2016)Starch-based films containing 70wt% of starch and a combination of poly(vinyl alcohol) and a low glass transition temperature polyurethane as plasticizer were prepared. The effect of PVA/PU ratio content on the morphology ... -
Surface, thermal, and mechanical properties of composites and nanocomposites of polyurethane PTFE nanoparticles
(2014)Films from blends of polyurethane and nano-polytetrafluoroethylene aqueous dispersions (PU/nanoPTFE) were prepared, and the effect of the addition of different amounts of PTFE nanoparticles (50 nm) was studied. The changes ... -
Synthesis and swelling behavior of pH-responsive polyurethane poly(2-(diethylamino)ethyl methacrylate) hybrid materials
(2013)Polyurethane (PU)/poly[2-(diethylamino)ethyl methacrylate] hybrids, having a chemical bond between the PU and acrylic moieties and with different compositions, were prepared by the dispersion polymerization of 2-(diethyl ... -
Synthesis, characterization and swelling behavior of new pH-sensitive hydrogels derived from copolymers of 2-hydroxyethyl methacrylate and 2-(diisopropylamino) ethylmethacrylate
(2012)The aim of this work was to synthesize and to characterize new pH-sensitive hydrogels that can be used in the controlled release of drugs, useful for dermal treatments or ophthalmology’s therapies. Copolymers containing ... -
The role of nanocrystalline cellulose on the microstructure of foamed castor-oil polyurethane nanocomposites
(2015)Nanocrystalline cellulose (CNC), obtained by sulphuric acid hydrolysis, was used to synthesize polyurethane foams (PUFs) based on a functionalized castor oil polyol and a Methylene diphenyl diiso- cyanate (MDI). Formulations ... -
Theoretical and experimental study of isothiazolinone adsorption onto ordered mesoporous silica
(Elsevier, 2016)Mesoporous silica SBA-15 particles were synthesized in order to evaluate their effectiveness asencapsulating agents for a commercial biocide composed of a mixture of methylisothiazolinone andchloromethylisothiazolinone ...
