Eletrodeposição de filmes do tipo Ni-X (X=P, Cu ou Cu-P) a partir de banhos contendo aspartato
(Universidade Federal de São Carlos, 2022-11-25)
In the present work, aspects related to the electrodeposition of Ni-based metal films - either pure metal or Ni-P, Ni-Cu, and Ni-Cu-P alloys - from baths containing aspartate complexes as electroactive species and hypophosphite ...
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 ...
