Géis superabsorventes de propionato acetato de celulose e acetato de celulose: síntese, caracterização e liberação controlada de pesticida
(Universidade Federal de São Carlos, 2011-12-16)
Hydrogels derived from cellulose acetate propionate (CAP) and cellulose acetate (CA) were synthesized with the cross-linking agents PMDA (Pyromellitic Dianhydride) and BTDA (Dianhydride 3, 3 ', 4, 4' Benzophenone ...
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 ...
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 ...
Filmes nanoestruturados de polianilina e argila para aplicação em sensores ambientais
(Universidade Federal de São Carlos, 2011-02-25)
In this study the development of environmental sensors began from the fabrication of nanoestrutured films obtained by the technique of Layer-by-Layer (LbL). The films of obtaining a nanocomposite material composed of ...
Uso da língua eletrônica na avaliação de soluções ultradiluídas.
(Universidade Federal de São Carlos, 2011-04-23)
In this work it was used an electronic tongue constituted by ultrathin films of distinct materials deposited on gold interdigitated electrodes. According to the impedance measurements taken, it was tested if the device is ...
