Espectroscopia eletrônica de moléculas halogenadas
(Universidade Federal de São Carlos, 2022-09-29)
We present a theoretical-experimental investigation of the valence state excitation of dichloromethane (CH2Cl2) and trichloromethane (CHCl3) molecules in the gas phase. The CH2Cl2 molecule was investigated using electron ...

(Universidade Federal de São Carlos, 2022-01-28)
Recently, the world has been facing several microbial infections that have caused great losses and fatalities. In this scenario, the development of new materials that can be used to fight these potentially pathogenic ...
Reações de fotooxigenação de pinenos em pinocarvonas, trans-pinocarveóis e mirtenal: uma abordagem em regime de fluxo contínuo
(Universidade Federal de São Carlos, 2022-04-18)
In this work, a continuous flow protocol to prepare (-)-pinocarvone, (-)-trans-
pinocarveol and (+)-myrtenal from (+)--pinene, (-)--pinene and -pinene through
photooxygenation reactions was described. Furthermore, ...
