Concretos refratários nanoligados para aplicação em unidades de craqueamento catalítico
(Universidade Federal de São Carlos, 2013-09-24)
In the petrochemical industry gasoline and LPG are produced in the fluid catalytic cracking unit (FCCU). The cracking occurs by the contact of crude oil with fluidized fine particles of a ceramic catalyst. The process ...
Processamento e caracterização de condutores de íons O2- a partir de cerâmicas BIMEVOX.
(Universidade Federal de São Carlos, 2005-11-11)
In this work, the processing of BIMEVOX family ceramics (ME-doped bismuth vanadate, ME =Cu2+, Fe3+ and Ti4+), obtained by precursor oxides fusion method was studied. The resulting powders were valued by X ray diffraction, ...
Modificação do Poli(hidroxibutirato) PHB com nucleantes e com o copolímero (etileno-co-acetato de vinila) - EVA
(Universidade Federal de São Carlos, 2008-03-19)
In this work, we sought to modify PHB, processing it in the melted state, and to
evaluate the effect of the modifications on its mechanical properties and
biodegradation characteristics. The following systems were therefore ...
Otimização da reciclagem de resíduos siderúrgicos por redução carbotérmica
(Universidade Federal de São Carlos, 2008-04-04)
The evolution of the world-wide production of steel in rates superior to 7% per year in the last five years, strongly driven by China, which got off 222,4 millions in 2003 for 489,0 million tons in 20071, leads to a strong ...
Preparação de argilas organofílicas para o desenvolvimento de nanocompósitos a partir de compostos de PVC plastificado
(Universidade Federal de São Carlos, 2009-12-15)
Nanocomposites of Plasticized PVC with organoclays have a large potential to improve the thermal resistance of PVC as well as its flame retardancy. However, a great problem in the production of PVC nanocomposites is the ...
Estudo da previsibilidade de tonalidades na decoração em vidrados transparentes
(Universidade Federal de São Carlos, 2008-12-18)
This study aimed to streamline the use and provide for the tone in the implementation of the decoration in glazed. The industry of traditional ceramics uses a range of dyes and pigments for the decoration of products. ...
Desenvolvimento de nanocompósitos à base de Mg armazenadores de hidrogênio processados por moagem de alta energia.
(Universidade Federal de São Carlos, 2003-10-29)
In the present work, Mg based nanocomposites were developed in the following systems: Mg TM, MgH2 TM, MgH2 MgF2 e MgH2 TM MgF2
(where TM means transition metal). The nanocomposites were processed by high
energy ...
Investigação das características de superplasticidade de um aço do sistema Fe-Mn-Al
(Universidade Federal de São Carlos, 2008-02-29)
The alloys of Fe-Mn-Al system have been rather studied in last few years indicating good potential for application, with the benefit of exhibiting 10 to 15% less density, coupled to good performance related to its mechanical ...
Estudo do transporte de íons Li+ em híbrido orgânico-inorgânico (SPHP) e nanocompósito (NHP) e seu desempenho em dispositivos eletrocrômicos.
(Universidade Federal de São Carlos, 2006-08-25)
The main goal of the present work is to describe the lithium ion transport
mechanism in a hybrid (SPHP) and nanocomposite (NHP) polyelectrolyte based
on complex conductivity analysis as a function of temperature. The ...
Injection overmolding of polycarbonate-aluminum alloys hybrid structures
(Universidade Federal de São Carlos, 2023-03-24)
Overlap joints between polycarbonate (PC) and aluminum alloys AA6061 and AlSi10Mg were manufactured by injection overmolding and evaluated regarding the interfacial structure and mechanical performance. The injection ...
