Nanocristais de celulose provenientes de fibras amazônicas com potencial aplicação na produção de nanocompósitos
(Universidade Federal de São Carlos, 2021-11-19)
Among all the natural polymers, we can highlight the use of cellulose, a mutable and profuse biopolymer in nature, which has enormous chemical variability due to the functionalization of its various hydroxyl groups. It can ...
Influência de nanopartículas de celulose na autoagregação de sais de bile
(Universidade Federal de São Carlos, 2024-02-05)
Surfactant self-aggregates can exhibit pronounced viscoelasticity, which can be modulated according to the addition of different molecules to the medium in which they are inserted. In this work, the effect of adding cellulose ...
Binchotan charcoal as a renewable source for partial replacement of calcined petroleum coke in the aluminum industry
(Universidade Federal de São Carlos, 2024-06-11)
Fossil-based materials have been used in the aluminum industry for many decades but cause major environmental impacts. The use of biomaterials can help to reduce these impacts. The aluminum industry uses calcined petroleum ...
