Grau de cisão de cadeia na degradação termomecânica de polímeros sob multiplas extrusões
(Universidade Federal de São Carlos, 2004-09-14)
One of the ways to follow the polymer degradation has been to calculate the average number of chain scissions (ns) that occurred during its
thermomechanical history. The average can be extended for each molecular weight ...
Síntese e caracterização de nanopartículas de óxido de estanho (SnO2) obtidas a partir de suspensões coloidais.
(Universidade Federal de São Carlos, 2004-09-23)
A novel chemical route was use to obtain colloidal suspensions of SnO2 nanoparticles. The synthesis is based on the hydrolysis reaction of tin chloride (II), and allows the preparation of nanocrystals at room temperature. ...
Estudo de tendências e oportunidades no desenvolvimento sustentável para a reciclagem de veículos e seus materiais.
(Universidade Federal de São Carlos, 2004-09-27)
The present study has the purpose of identifing and analysing the tendencies of vehicle recycling technologies focusing on shredder residue, PVC and heavy metals due to the importance of this area to the development ...
Desenvolvimento de um novo fundente para substituir o feldspato em composições de grês porcelanato
(Universidade Federal de São Carlos, 2004-08-27)
Amongst the various types of ceramic tiles, the porcelainized stoneware tile stands out due to its technical properties (low water absorption, high mechanical strength and high abrasion, chemical attack and frost resistance). ...
Estudo da influência da adição de compostos de boro na resistência à oxidação de refratários a base de carbeto de silício-liga de nitreto.
(Universidade Federal de São Carlos, 2004-08-06)
In this work, boron was added in a commercial silicon carbide bonded silicon nitride refractory and its influence has been evaluated. These materials have been used as high temperature structural ceramic due to their ...
