Blendas de polietileno e amido termoplástico modificado
(Universidade Federal de São Carlos, 2011-04-06)
The development of materials derived from renewable or biodegradable resources has attracted attention from academic and industrial sectors due to the growing need for replacement of synthetic materials derived from renewable ...
Estudo e caracterização de composições de coque e fibras vegetais (bagaço de cana e madeira) para aplicação na produção de briquetes
(Universidade Federal de São Carlos, 2011-02-25)
"Green" petroleum coke is a solid product, obtained from the cracking of heavy residual oils in the waste conversion units called delayed coking units (UCR). The market for application of "green" coke is very broad, perhaps ...
Incorporação em lipossomos da aloína e imobilização em filmes nanoestruturados para aplicação em liberação modificada de fármacos
(Universidade Federal de São Carlos, 2011-03-31)
Currently, thanks to the high due technological development, a new class of systems has been explored for drug delivery systems, or controlled release of drugs. These systems have great importance as a rare drug in an ...
Estudo da compactação de resíduos lignocelulósicos para utilização como combustível sólido
(Universidade Federal de São Carlos, 2011-02-08)
The production of energy from the combustion of lignocellulosic materials is an interesting way to waste recovery. Two main factors hampering the use of these residues as fuel are the low density and the high moisture ...
Estudo comparativo das tensões na interface de compósitos de resina epóxi reforçados com fibras de carbono, aramida e vidro.
(Universidade Federal de São Carlos, 2011-02-08)
Currently, composite materials are being used in several areas in substitution of some metallic alloys regarding to its superior properties and greater project flexibility. Therefore, synthetic fibers reinforced epoxy resin ...
