Influência da incorporação de aditivos nas propriedades do Poli (Hidroxibutirato-co-hidroxivalerato) - PHBV
(Universidade Federal de São Carlos, 2008-08-05)
The concept of environmentally correct products has been exhaustively discussed and, today, the use of biodegradable polymers appears as a feasible alternative for the problem of inadequate disposal of plastic waste products. ...
Influência da adição de um fundente sintético no mecanismo de coloração final de revestimentos cerâmicos
(Universidade Federal de São Carlos, 2011-08-12)
The presence of iron oxide in ceramic tile mass contributes to the reddish color firing of the products leading to a lower aggregate value, not to be regarded as a "noble" ceramic. However, the use of raw materials with ...

This study focuses on analyzing the current situation and perspectives of materials selection and utilization, like composites, decorative laminates and films, and others, in business aircraft, particularly in furnishings ...
Sinterização, cristalização, desenvolvimento e caracterização de vitrocerâmicas de baixo coeficiente de expansão térmica do sistema Li2O - Al2O3 SiO2 (LAS)
(Universidade Federal de São Carlos, 2010-10-15)
Glass-ceramics based on the Li2O-Al2O3-SiO2 (LAS) system represent the most important (commercial) family. They are required for applications where extreme dimensional stability and thermal shock resistance are of utmost ...
Síntese e caracterização de nanofitas de óxido de estanho.
(Universidade Federal de São Carlos, 2004-10-08)
Tin oxide nanoribbons were synthesized by a carbothermal method, which is based on evaporation-condensation reactions. The source material was composed of commercial tin dioxide (SnO2) powders mixed with carbon black. This ...
Resistência ao desgaste abrasivo da liga Fe66B30Nb4 processada por conformação por spray
(Universidade Federal de São Carlos, 2009-12-17)
Aiming at the improvement of the wear resistance of a glass former composition, the Fe66B30Nb4, the alloy was modified with the addition of Ti, resulting in the theoretical compositions: Fe63B29Nb4Ti4 (SF1) and Fe65B30Nb4Ti1 ...
Monitoramento in-line da formação de nanocompósitos PP/MMT via intercalação no estado fundido
(Universidade Federal de São Carlos, 2008-08-04)
The aim of this work is to monitor in-line, using an optical detector fitted at the extruder die exit, the formation of PP/MMT nanocomposites during polymer melt compounding. The intensity of the detector´s signal is ...
