Preparation and evaluation of carbon supported catalysts for ethanol oxidation
(Springer, 2013)
Supported PtSnIr/C, PtSn/C, and IrSn/C catalysts with potential application in a direct alcohol fuel cell were prepared by chemical reduction employing Pechini methodology. The catalyst particles were characterized by ...
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 ...
Dimensional stability, fire performance and decay resistance in wood impregnated with alkylalkoxysilanes
(2013-11-20)
The wood, very heterogeneous and complex material, changes its volume by water absorption or desorption causing swelling or shrinkage and also it can be degraded both by action of microorganisms and fire; the above-mentioned ...
Decay resistance and dimensional stability of Araucaria angustifolia using siloxanes synthesized by solegel process
(Elsevier, 2013-05-16)
Solid wood specimens of Araucaria angustifolia were impregnated with alkoxysilanes hydrolyzed and
condensed “in situ” by the solegel process. Alkoxysilanes selected were aminopropyl methyldiethoxysilane and aminopropyl ...
Pinturas híbridas de terminación sobre fondos anticorrosivos de zinc modificados
(Atipat, 2013-10-01)
Las pinturas basadas en zinc metálico presentan una mayor eficiencia contra la corrosión en relación con otros recubrimientos. Sin embargo, éstas necesitan generalmente una pintura de terminación ya sea para conferirle al ...
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 ...
Hybrid finishing coatings applied on laminar zinc primers
(American Chemical Society, 2013-05-29)
Hybrid finishing coatings were formulated with several film-forming materials and reinforcement fibers. In all cases, the same tri-pigmented epoxy-polyamide coating based on laminar zinc was used as primer. The results ...
