Preparation and characterization of bionanocomposites based on protein and cellulose nanocrystals by continuous casting
(Universidade Federal de São Carlos, 2020-12-11)
This Ph.D. thesis covers the production and characterization of gelatin-cellulose nanocrystals (CNCs) bionanocomposite films intended for multifunctional food packaging. The up-scalability of the gelatin/CNCs films was ...
Mineração de textos de patentes para monitoramento tecnológico, identificação de aplicações e seleção de materiais: estudo de caso em desenvolvimentos de aços
(Universidade Federal de São Carlos, 2020-11-26)
The growing number of options in materials leads to increasing complexity of the process to select the most suitable to perform a function in a product or to choose a competitive application for a newly developed material. ...
Crack network monitoring upon curing and drying of high-alumina MgO-containing refractory castable via digital image correlation
(Universidade Federal de São Carlos, 2020-12-23)
MgO particles are added to high-alumina refractory castable formulations to
form spinel at high temperatures. However, these particles react with water forming brucite, which causes heterogeneous expansions in the material ...
Armazenagem eletroquímica de hidrogênio: um estudo do comportamento dos metais Pd, Nb e V
(Universidade Federal de São Carlos, 2020-07-22)
Developing safe, reliable, efficient and cost-effective methods for hydrogen storage is a scientific and technological challenge. Among possible methods to store hydrogen, storing it in tanks in the liquid or compressed ...
Estudo sistemático da condutividade iônica de vitrocerâmicas NASICON: influência de tratamentos isotérmicos e novas substituições iônicas
(Universidade Federal de São Carlos, 2020-09-24)
The synthesis of solid electrolytes and the optimization of their ionic conductivity are topics of scientific interest since these components are essential for the current density and the half-life of the sodium batteries. ...
Otimização do processo de secagem de concretos refratários
(Universidade Federal de São Carlos, 2020-08-11)
The drying step of hydraulic-bonded refractory castables is usually carried using conservative and long heating schedules, in order to preserve the microstructure of dense ceramic linings and inhibit explosive spalling ...
Perspectivas e estratégias para melhoria da educação em engenharia de materiais brasileira
(Universidade Federal de São Carlos, 2020-09-10)
Engineering Education (EE) has greatly expanded in Brazil over the last decades and, over the last few years, some criticisms to the Brazilian EE started to gain traction. A reform to the national guidelines for engineering ...
Previsão de viscosidade e temperatura liquidus de vidros óxidos via redes neurais artificiais
(Universidade Federal de São Carlos, 2020-04-30)
The number of glass compositions that have already been studied (~10^5) is many times smaller than the potential glass compositions (~10^52). The traditional method “cook and look” all of the potential compositions to ...
Influence of Bobbin Tool Friction Stir Welding (BT-FSW) variants on the microstructure and properties of AA2060 and AA2196 aluminum alloys
(Universidade Federal de São Carlos, 2020-06-18)
In order to reduce total costs in aircrafts production, operation and maintenance, materials and processing techniques have been continuously further optimized. In this scenario, aluminum-lithium alloys have been studied ...
