Catalisadores baseados em nitretos de carbono grafíticos e metais de transição: síntese e aplicações
(Universidade Federal de São Carlos, 2022-03-24)
Carbon nitrides are polymeric compounds with a C3N4 stoichiometric ratio and formed by sp2 nitrogen bonds. Most of the works in the literature uses polymeric carbon nitride as a catalyst for application in organic reactions, ...
Estudo metabolômico dos constituintes voláteis de algodoeiro submetido à interações bióticas e abióticas e mecanismos de indução de resistência
(Universidade Federal de São Carlos, 2020-02-17)
Plants have developed several defense strategies against herbivory, one of which is the response of induced defenses that represents the biosynthesis of phytotoxic molecules through attack. Plant resistance mechanisms can ...
Sensores nanoestruturados compostos por nanofibras de dióxido de titânio modificadas com polímeros condutores visando monitoramento de compostos orgânicos voláteis
(Universidade Federal de São Carlos, 2020-03-18)
The growth of urbanization and anthropogenic activities have been increasing the emission of polluting gases in the atmosphere. Considering the high toxicity of some of these gases, it becomes necessary to develop new ...
