(Universidade Federal de São Carlos, 2022-05-11)
The low processability of chitosan and the obtaining of materials with low structural stability constitute substantial limitations to the commercial use of chitosan, especially in biomedical applications. Furthermore, the ...
Desenvolvimento de eletrólitos nanocompósitos de nafion e nanocristais de celulose para uso em células eletrolíticas com membrana trocadora de prótons (PEMECs)
(Universidade Federal de São Carlos, 2022-04-20)
Proton exchange membrane water electrolysis (PEMWE) performs the
electrolysis of water to produce hydrogen, a source of clean and renewable
energy. The most used commercial electrolyte in PEMWE is the Nafion
membrane, ...
Estudo da influência de contraíons nas propriedades eletroquímicas, eletromecânicas e térmicas de compósito polímero ionomérico metal (IPMC) de Náfion®/Pt
(Universidade Federal de São Carlos, 2022-06-21)
In the field of soft actuators, ionomeric polymer metal composite like devices
(IPMCs) are a trend, as they display great displacement when a low electric
potential is applied. Its work mechanism is related to the migration ...
Caracterização óptica on-line das misturas dispersiva e distributiva na extrusão dupla rosca
(Universidade Federal de São Carlos, 2022-12-14)
In this work, the effect of different kneading blocks on the dispersive and distributive mixing levels of a diluted PS/PA6 mixture along the screw profile of a twin-screw extruder was investigated via online monitoring of ...
