Synthesis and characterization of Biosilicate/F18 bioglass scaffolds for dental application
(Universidade Federal de São Carlos, 2019-10-16)
In this work, Biosilicate scaffolds were synthesized using the foam replica technique. Biosilicate is highly bioactive, biodegradable, antibacterial, and non-toxic. Despite of these properties, Biosilicate scaffolds present ...
Estudo da transição de fase sólido-vapor e da eficiência de inibidores voláteis de corrosão quando incorporados em matrizes poliméricas
(Universidade Federal de São Carlos, 2005-08-05)
In this work it is proposed a potential barrier model between solid and vapor phases. As a consequence of this model it is developed a method to measure vapor pressure as low as 10-5 Pa. A thermodynamic system consisting ...
Cristalização e sinterização de bio vidros do sistema Na2O-CaO-SiO2-P2O5
(Universidade Federal de São Carlos, 2001-03-30)
The objective of this work was to study crystallisation and sintering of Bio-glasses of Na2O CaO SiO2 P2O5 aiming at the improvement of the mechanical properties. In order to study the development of glass-ceramics in this ...
Processamento e caracterização de nano-biocompósitos de Poli(hidroxibutirato-co-hidroxivalerato)/montimorilonita modificada organicamente (PHBV/OMMT) com adição de plastificante
(Universidade Federal de São Carlos, 2010-12-10)
A current search for new materials that are economically viable and ecologically correct has led to the implementation of many studies aimed at improving the properties and processability of biodegradable polymers. This ...
Degradação da resistência à corrosão de aços inoxidáveis duplex, devido ao envelhecimento em baixas temperaturas por tempos prolongados.
(Universidade Federal de São Carlos, 2004-08-30)
Although duplex stainless steels exhibit good performance in many severe corrosive environments, their corrosion resistance can be hampered by precipitation of chromium (Cr) rich phases during aging heat treatments.
Micr ...
Avaliação do dano por choque térmico em concretos refratários via espectroscopia acústica ressonante não-linear
(Universidade Federal de São Carlos, 2012-03-02)
In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...
Análise da processabilidade de blendas PBT/ABS compatibilizadas in situ com copolímeros acrílicos
(Universidade Federal de São Carlos, 2007-12-14)
Poly(butylene terephthalate)/acrylonitrile-butadiene-styrene (PBT/ABS) blends show high toughness at room temperature, low ductile-brittle transition temperature and stable morphology when compatibilized. The flowability ...
Uso do método do trabalho essencial de fratura (EWF) para avaliar a tenacidade de blendas poliméricas.
(Universidade Federal de São Carlos, 2005-03-11)
Initially it was made a well elaborated study on the essential work
of fracture method (EWF) using the polyamide 6 (PA6) because this polymer
shows high difficult to evaluate its toughness. The PA6 is a semi-crystalline
polymer, ...
