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 ...
Correlação estrutura x propriedades de transporte de CO2 em membranas de poli(éterimida)/líquido iônico
(Universidade Federal de São Carlos, 2017-09-28)
The increase in the emission of carbon dioxide (CO2) from the burning of fossil fuels contributes directly to changes in the environment. For post-combustion CO2 capture, the use of polymer membranes has gained prominence ...
