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 ...
Desempenho de filmes soprados multicamada de blendas de polipropileno e copolímeros de etileno
(Universidade Federal de São Carlos, 2012-08-30)
Polypropylene (PP) and polyethylene (PE) are widely used in the flexible packaging market individually as mono or multilayer films. Blending PP and PE in coextruded films has shown limited commercial applications due to ...

Recently, intensive studies have been conducted with biomaterials aiming their application as synthetic grafts for reparation and maintenance of bones, teeth and cartilage tissues that have been damaged or lost due to ...
Influence of surface treatments on corrosion resistance properties of ultrafine grained titanium alloys for biomedical applications
(Universidade Federal de São Carlos, 2019-08-09)
Titanium and its alloys are used as biomaterials because their excellent combination of high corrosion resistance, low modulus of elasticity and biocompatibility. However, titanium and its alloys cannot meet all the clinical ...
Estudo da indução da grafitização da resina fenólica fenol/formaldeído
(Universidade Federal de São Carlos, 2019-08-14)
Among the probable carbon sources, there are the polymers, as the phenolic resin, which produces residual carbon around 60% wt./wt. after thermal treatment. It is classified as non-graphitizable, because it has not graphitic ...
