Obtenção de nanofibrilas de celulose de árvores pioneiras amazônicas e processamento de nanobiocompósitos de PHBV/nanofibrilas de celulose de eucalipto no estado fundido
(Universidade Federal de São Carlos, 2014-11-24)
This research project aimed to develop high value-added products such as
biodegradable composites reinforced with cellulose nanofibrils (CNF) making use of
Amazonian pioneer plant species, useful in restoration of degraded ...
Influência de aditivos pró-degradantes nas degradações abiótica e biótica do polietileno de alta densidade
(Universidade Federal de São Carlos, 2015-03-06)
High density polyethylene (HDPE) is widely used in the manufacture of
packaging disposables and in order to minimize the environmental impact
caused by disposal, have been incorporated, into the HDPE, additives that
promises ...
União pontual por fricção (“friction spot joining”) de alumínio 6181-T4 com compósito laminado de poli(sulfeto de fenileno) e fibra de carbono (CF-PPS)
(Universidade Federal de São Carlos, 2015-02-26)
The friction spot joining (FSpJ) emerges as an alternative and innovative
technique for producing polymer-metal hybrid structures. This technique was
developed and patented by HZG / Germany in 2012. The process uses ...
Processos difusionais, cristalização e escoamento viscoso em dissilicato de bário vítreo
(Universidade Federal de São Carlos, 2014-04-24)
In this work, we analysed if the viscous flow successfully describes the transport of crystal nucleation and crystal growth structural units that occur at the liquid/crystal interface. In order to do this, we calculated ...
Desenvolvimento de nanocompósitos de blendas PA6/ABS compatibilizadas com copolímeros funcionalizados
(Universidade Federal de São Carlos, 2014-09-22)
Nanocomposites based on polyamide 6 (PA6) and acrylonitrile-butadienestyrene
(ABS) blends compatibilized with styrene-maleic anhydride-acrylonitrile
(SANMA) and methyl methacrylate-maleic anhydride (MA-MMA) were prepared
by ...
Friction riveting of TI-6AL-4V and pultruded glass fiber reinforced thermoset polyester hybrid joints
(Universidade Federal de São Carlos, 2015-12-18)
Friction Riveting is an innovative spot joining technology for metal-polymer
hybrid structures. This MSc thesis provided for the first time in the literature, a
fundamental understanding on the Friction Riveting process ...
Desenvolvimento de blendas de TPS, PCL E PLA e seus nanocompósitos com nanowhiskers de celulose de gravatá
(Universidade Federal de São Carlos, 2015-12-15)
The objective of this project was the study of polymer blends of thermoplastic starch (TPS), poly(ε-caprolactone) (PCL) and poly(lactic acid) (PLA) and the extraction of celulose nanowhisker from gravatá (Bromelia balansae) ...
Desenvolvimento de compósito de poliuretano reforçado com nanofibrilas de celulose isoladas de candeia (Eremanthus erythropappus)
(Universidade Federal de São Carlos, 2016-02-26)
Candeia (Eremanthus erythropappus) is an important raw material due to the essential oil that can be extracted from the whole tree. The essential oil contains (-)--bisabolol that has an active principle with pharmacological ...
Turbidimetria in-line na quantificação do tamanho de partícula de misturas poliméricas na extrusão
(Universidade Federal de São Carlos, 2017-10-16)
The morphology of mixtures and polymeric compounds is usually evaluated by off-line characterization methods, which require time for sample preparation and analysis of results. In-line rheo-optical characterization techniques ...
Estudo da curvatura central das placas cerâmicas para revestimentos : a influência da fusibilidade e coeficiente de expansão térmica da camada de engobe nas curvaturas desenvolvidas durante e após a queima
(Universidade Federal de São Carlos, 2017-09-05)
Most ceramic tiles have a slip layer and this has a significant influence on the characteristics of the ceramic tiles. In contrast to this reality, the specialized literature on engobes is sparse and superficial. It is ...
