(Universidade Federal de São Carlos, 2019-04-30)
Currently, there is considerable interest in developing lead-free composites in the scientific area. This is occurs due to the growing demand for new multifunctional materials with potential technological applications. ...
Estudo da incorporação de nanopartículas de óxido de zinco e pentóxido de nióbio em polietileno linear de baixa densidade
(Universidade Federal de São Carlos, 2019-03-29)
Linear low-density polyethylene (LLDPE) is one of the most widely used materials in greenhouse covering, due to its low cost and transparency to photosynthetically active radiation up to 80%. However, this polymer also ...
Analysis of crack propagation in the wedge splitting test via digital image correlation and finite element analyses
(Universidade Federal de São Carlos, 2019-02-19)
Castable refractories are applied in dangerous environments in which it is unpractical to avoid crack initiation. Therefore, their microstructure is usually complex in order to hinder crack propagation by toughening ...
Morfologia de ionômero E/MMA-Na+ proposta por técnicas termo-ópticas
(Universidade Federal de São Carlos, 2017-10-19)
The DSC low temperature endothermic peak shown by sodium neutralized poly(ethylene-random-methacrylic acid) (E/MAA) ionomers has been shown here to be the result of two different and dependent morphological transformations, ...
Preparação de membranas poliméricas porosas a partir de técnicas de espumação com agentes físicos de expansão
(Universidade Federal de São Carlos, 2016-07-07)
The objective of this master’s thesis was to develop a process of
manufacturing porous polymer membranes for microfiltration by a one-step
foaming technique, using carbon dioxide (CO2) as physical blowing agent and
ethanol ...
Desenvolvimento e caracterização de concretos refratários ligados quimicamente por fosfatos para aplicação em indústrias petroquímicas
(Universidade Federal de São Carlos, 2017-10-05)
The objective of this work was the development of chemically phosphatebonded
refractories for applications in petrochemical industries due to their
suitable properties such as high green mechanical strength, erosion ...
Efeitos das condições de queima e densidade aparente sobre a sobrequeima em porcelanatos
(Universidade Federal de São Carlos, 2015-08-05)
The phenomenon of overfiring manifests in porcelain tiles and other
products with high degree of vitrification, as a consequence of the expansion of
gases trapped in closed pores, in the final stages of sintering. When ...
Condutividade iônica e eletrônica em vidros 0,50[xAg2O(1-x)V2O5].0,50P2O5
(Universidade Federal de São Carlos, 2016-10-27)
Mixed conductive glassy materials have in their composition, in addition
to a glass former, a metallic element in two oxidation states and ions with high
mobility, generally alkaline or Ag+ ions. These materials can be ...
Nanocompósitos de poliuretano comercial e nanopartículas híbridas de núcleo Fe3O4 funcionalizado com capa orgânica de Poli(1,4-Butanodiol)
(Universidade Federal de São Carlos, 2018-02-23)
The use of inorganic nanoparticles in polymer nanocomposites allows gain in mechanical resistance and new properties. However, the incorporation of organic layer functionalized nanoparticles alters the material’s properties ...
