Análise sistêmica dos fornos de cozimento de anodo para a indústria de alumínio
(Universidade Federal de São Carlos, 2010-05-05)
The recent global economic crisis allied with the trend for sustainable
companies and countries have meaningfully changed the aluminum area.
Previously, the productivity was the main focus of the metal producer and ...
Blendas de PHBV e PCL para uso em dispositivos de osteossíntese
(Universidade Federal de São Carlos, 2010-12-15)
This study aimed to develop and characterize polymer blends using biodegradable and bioabsorbable polymers poly (hydroxybutyrate-co-valerate) PHBV with 12% valerate, and poly (ε-caprolactone) PCL, in order to make ...
Caracterização do comportamento de desgaste de cerâmicas de alumina densa : efeitos de parâmetros do ensaio do tipo pino no disco
(Universidade Federal de São Carlos, 2010-12-08)
Searching for wear resistant materials, attention has been paid to Si3N4, SiC, Al2O3 and ZrO2 ceramics due to their better properties as compared to other materials. Although ceramic are brittleness, improvements on the ...
Dispositivo óptico para medida em tempo real da birrefringência de polímeros durante a extrusão
(Universidade Federal de São Carlos, 2010-03-05)
The main objectives of this project were the development and application of an optical device to measure in real time the flow induced birefringence during the polymer extrusion. The linearly polarized light intensity ...
Desenvolvimento de ligas de Mg em formas maciças para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2010-06-29)
In the present work, bulk magnesium metallic hydrides (MgH2 and Mg2FeH6) were produced. Commercially pure Mg and mixtures of 2Mg-Fe were processed by severe plastic deformation (SPD) by using High Pressure Torsion (HPT) ...
Influência da nanoargila no envelhecimento higrotérmico de compósitos de polipropileno / PP maleado / fibra de vidro
(Universidade Federal de São Carlos, 2010-05-21)
In short glass fiber (GF) reinforced polypropylene (PP) composites, despite of the chemically inert and non-polar nature of the matrix, the fiber-matrix interfacial integrity may be compromised in a hygrothermal active ...
O uso de B4C como aditivo de sinterização de SiC-Si3N4 visando o aumento da resistência à oxidação
(Universidade Federal de São Carlos, 2010-02-04)
In order to fulfill modern market requirements based on increased search for SiC Si3N4 products with high performance and good cost/benefit ratio, there is a natural need for additives able to sinter as well as decrease ...
Desenvolvimento de compostos poliméricos biodegradáveis modificados com cargas e fibras naturais vegetais
(Universidade Federal de São Carlos, 2010-08-02)
Due to environmental and economical concerns, the study and utilization of raw materials coming from natural renewable resources have grown significantly in the last years. The utilization of biodegradable polymers has ...
Análise sistêmica das massas de tamponamento para altos-fornos
(Universidade Federal de São Carlos, 2010-05-05)
The increase in the world steel production mainly observed in the last decade demanded a significant growth in the hot metal production through the blast furnace process. A key point in blast furnaces operation is related ...
Processamento de nanofibras de poliamida 66 / nanotubos de carbono de múltiplas camadas por eletrofiação
(Universidade Federal de São Carlos, 2010-03-26)
Nanocomposite fibers with polymer matrix have many applications, such as protective clothing, filtration and artificial blood vessels. Many of these applications require that the fiber has nanometric size due to some ...
