Vitrocerâmica altamente bioativa, de boa resistência mecânica e baixo módulo elástico
(Universidade Federal de São Carlos, 2019-09-03)
Bioactive glass and glass-ceramics have the property of binding directly to living tissue. However, from mechanical performance, these materials have some disadvantages such as low fracture resistance. Some properties ...
Avaliação da anomalia da teoria de nucleação clássica em vidros silicatos
(Universidade Federal de São Carlos, 2021-07-13)
Under some conditions, the Classical Nucleation Theory (CNT) provides a good description of the temperature dependence of the experimental homogeneous nucleation rates in supercooled liquids. Allegedly, however, it strongly ...
Compósito magnético de matriz vítrea bioativa para hipertermia
(Universidade Federal de São Carlos, 2020-03-19)
Bone cancer is a rare type of neoplasm, but with high rates of new cases annually. With several therapies available for this pathology, a controlled hyperthermia technique is promising. This technique uses the response of ...
Coatings cerâmicos de alta emissividade como soluções energéticas para fornos industriais
(Universidade Federal de São Carlos, 2021-08-30)
Aiming at alternatives to reduce the impacts from the excessive consumption of non-renewable energy sources by the industrial sector, the present work highlights an important technological aspect with the development of ...
Método de controle de trajetória de atuadores ipmc baseados em nafion® utilizando técnica de visão de máquina em ambiente com umidade relativa controlada
(Universidade Federal de São Carlos, 2021-08-13)
Ionomeric polymer-metal composites (IPMC) consist of an electroactive polymeric matrix coated on both sides with a noble metal. When applying an electrical potential difference, the polymeric membrane changes its thickness, ...
Perovskitas óxidas para aplicação eletroquímica e fotovoltaica
(Universidade Federal de São Carlos, 2019-07-26)
This work aimed to investigate the production of lanthanum perovskites LaCoO3 and LaFeO3 in the form of thin films and to evaluate their use as catalysts for water splitting as well as absorbers for photovoltaic devices. ...
Comportamento mecânico sob fadiga de compósitos de polipropileno com reforço híbrido de fibras e microesferas ocas de vidro
(Universidade Federal de São Carlos, 2018-02-05)
Short glass fiber (GF) reinforced polypropylene (PP) composites can be hybridized with hollow glass beads (HGB) in order to minimize the adverse effects arising from the preferential fiber orientation in injection molded ...
Estudo das propriedades mecânicas, térmicas e de transporte do compósito com carbonato de cálcio nano e microparticulado em polipropileno
(Universidade Federal de São Carlos, 2011-03-04)
In this work were determined and compared to mechanical, thermal and barrier of the polypropylene composites containing micropartilate and microparticulate calcium carbonate. To prepare the composites, the filler was ...
Simulação numérica do processo de secagem de concretos refratários em aplicações tecnológicas
(Universidade Federal de São Carlos, 2022-03-21)
Refractory ceramics are used in high temperatures due to their unique properties that enable a high thermal and chemical stability, mechanical strength, thermal properties and others. These materials are split into two ...
Avaliação dos agregados de resíduos da construção civil em matriz geopolimérica visando aplicação em pisos intertravados
(Universidade Federal de São Carlos, 2022-04-14)
The production of Portland cement (PC) is seen as aggravating the environment,
so scientists and engineers look for alternatives to replace this type of binder.
Geopolymers have the potential to replace CP, as it aims ...
