Insights into the mechanism of an S N2 reaction from the reaction force and the reaction electronic flux
(American Chemical Society, 2012)
The mechanism of a simple S N2 reaction, viz; OH - + CH 3F = CH 3OH + F - has been studied within the framework of reaction force and reaction electronic flux. We have computationally investigated three different types of ...
The mechanism of Menshutkin reaction in gas and solvent phases from the perspective of reaction electronic flux
(Springer Verlag, 2014)
© 2014, Springer-Verlag Berlin Heidelberg.The mechanism of Menshutkin reaction, NH3 + CH3Cl = [CH3–NH3]+ + Cl-, has been thoroughly studied in both gas and solvent (H2O and cyclohexane) phase. It has been found that solvents ...
Conceitos de química dos ingressantes nos cursos de graduação do Instituto de Química da Universidade de São Paulo
(Sociedade Brasileira de Química, 2008)
A diagnostic instrument was developed to evaluate the basic chemistry concepts held by freshmen students of the three Chemistry undergraduate courses offered by the University of São Paulo. The instrument minimizes the use ...
Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
