Desenvolvimento de concreto geopolimérico leve: viabilidade de aplicação no setor da construção civil
(Universidade Federal de São Carlos, 2023-07-28)
Portland cement is the main component of conventional concrete, considered
the second most consuming material in the world, but its manufacture
accentuates the greenhouse effect. Studies show that the production of ...
Development of bio-inspired electromechanical devices based on PBMA-b-(PSS-r-PS) amphiphilic block copolymer
(Universidade Federal de São Carlos, 2024-04-08)
Technological advances in the aerospace, biomedical, and robotics industries stimulate the need for innovative and sustainable devices, such as electromechanical devices (EMDs), which are bio-inspired materials capable of ...
Caracterização óptica on-line das misturas dispersiva e distributiva na extrusão dupla rosca
(Universidade Federal de São Carlos, 2022-12-14)
In this work, the effect of different kneading blocks on the dispersive and distributive mixing levels of a diluted PS/PA6 mixture along the screw profile of a twin-screw extruder was investigated via online monitoring of ...
Estudo da sinterização de compósitos densos de Al₂O₃ contendo inclusões nanométricas de ZrO₂
(Universidade Federal de São Carlos, 2009-06-22)
The search for materials that posses exceptional hardness, resistance to high temperatures and chemical stability had expanded the areas of application and use of ceramic materials. The development of research about ...
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 ...
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 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 ...
Desenvolvimento de um equipamento para avaliar propriedades elásticas de cerâmicas refratárias a altas temperaturas pelo método de ressonância de barras.
(Universidade Federal de São Carlos, 2002-09-12)
The knowledge of the elastic properties has been of fundamental
importance for the understanding of the limitation of the useful life of structural
refractory ceramics. Those properties characterize the elastic rigidity ...
Determinação da energia de fratura em materiais cerâmicos em altas temperaturas.
(Universidade Federal de São Carlos, 2005-03-11)
In this work, the main objective was to determine the energy of fracture in
ceramic materials, focused on refractories, at high temperatures and to inquire
the interference of the creep on this measurement. Therefore, ...
