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 ...
Cristalização e relaxação em vidros óxidos uma tentativa de solução do Paradoxo de Kauzmann
(Universidade Federal de São Carlos, 2021-09-03)
The quest for a solution to Kauzmann’s Paradox has been a lifelong
journey for many glass scientists over the last seventy years. The idea that this
paradox may violate the Third Law of Thermodynamics is ...
Influência dos contornos de grãos nas propriedades elétricas de hematita policristalina modificada com diferentes elementos químicos
(Universidade Federal de São Carlos, 2020-03-13)
The use of molecular hydrogen produced by photoelectrochemical cells is an alternative to fossil fuels, economically and environmentally. Hematite (α-Fe2O3) is a promising candidate to the realization of photoelectrochemical ...
On-line FTIR spectroscopy system for extrusion-based process analysis
(Universidade Federal de São Carlos, 2021-11-11)
Polymer processing is a fundamental key to achieve the desired properties to reach the needs of polymer applications. Thus, it is important to understand how the processing can contribute to material characteristics during ...
Efeito do tamanho e distribuição de tamanho inicial das partículas da hematita, na cinética de sinterização assistida por micro-ondas
(Universidade Federal de São Carlos, 2021-11-26)
This thesis aimed to study the effect of the initial particle size and its
distribution of hematite on microwave-assisted sintering kinetics. Two synthesis
methods were used: sol-gel and seeded-mediated growth. By sol-gel ...
