(Universidade Federal de São Carlos, 2015-01-30)
The study of calcium phosphate coatings, in particular hydroxyapatite for applications on metal implants, has increased in order to improve the interaction between the tissue and the implant. In this work, calcium phosphate ...
Avaliação dos métodos de imersão, spray e dinâmico utilizados na fabricação de filmes nanoestruturados de nanofolhas de grafeno pela técnica de automontagem.
(Universidade Federal de São Carlos, 2014-11-29)
In this work we have compared the way graphene oxide nanoplatelets are nanostructured in bilayers of poly(diallyldimethylammonium chloride) (PDDA) and reduced graphene oxide stabilized in poly(sodium 4-styrenesulfonate) ...
Nanocompósito de acetato de celulose reforçado com whiskers extraídos da macrófita Typha domingensis
(Universidade Federal de São Carlos, 2013-02-19)
Composite is a material composed mainly of two phases, the matrix which is continuous and surrounds the other phase, which is called the dispersed phase or stage reinforcement. Nanocomposites are obtained by incorporating ...

Fabricação e caracterização de filmes nanoestruturados de nanotubos de carbono e polianilina para aplicação em sensores ambientais na detecção de 2-clorofenol.
(Universidade Federal de São Carlos, 2012-03-02)
Organochlorine compounds exhibit high toxicity, environmental persistence and tendency to bioaccumulate. This pollutant can spread through the air and water, affecting humans and the environment. In this context, this study ...
Influência da deposição de filmes finos organosilicones na fotodegradação do polipropileno
(Universidade Federal de São Carlos, 2013-07-31)
It is known that polypropylene is degraded in the presence of UV radiation, making difficult its use in applications where occurs this kind of radiation. This situation arises a need to improve the properties of polypropylene ...
Moldagem de briquetes com finos de carvão vegetal aglutinados com parafina: caracterização de algumas propriedades.
(Universidade Federal de São Carlos, 2013-02-07)
The aim of this study was to evaluate the properties of briquettes made from charcoal fines bonded with paraffin. To prepare them were used three fractions of fine coal (20, 35 and 60 mesh) and a binder, the paraffin. ...
Estudo da influência da deformação por cisalhamento extrusão em canal angular e laminação assimétrica nas propriedades mecânicas do alumínio AA 1050
(Universidade Federal de São Carlos, 2014-08-18)
It is known that the formability of aluminum alloy AA1050 is not favored when sheets are produced by conventional rolling due to the appearance of intense cube texture {100} <100> after recrystallization heat treatment. ...
