Estudo das propriedades ópticas do nanocompósito de dissulfeto de molibdênio e nanofibrilas de celulose
(Universidade Federal de São Carlos, 2019-03-01)
Studies on nanocomposite dicalcogenated transition metals (TMDs) with cellulose nanofibrils (CNFs), called TMD-CNFs, are still scarce in the literature. Among the TMDs, molybdenum disulphide (MoS2) has great application ...
Síntese e Caracterização do Poli(PCL-TMC)uretana para utilização como Biomaterial
(Universidade Federal de São Carlos, 2017-03-03)
Among the polymers widely investigated as materials for tissue engineering, polyurethane has its place of prominence, mainly due to the high flexibility and tenacity. The need for devices with certain mechanical properties ...
Termogravimetria aplicada para caracterização da biomassa
(Universidade Federal de São Carlos, 2018-03-02)
Issues related to renewable energy have been increasingly addressed and discussed. In this
context, biomass is an alternative for the generation of renewable and available energy. Its
