Grounding mechanism

The quicklime may be ground mechanically before addition, but this is less convenient than disintegrating it by the cautious addition of water. 

These studies, which employed density functional theory (DFT) methods (B3LYP/LANL2DZ/Gaussian 98) proposed that the reactions of all alkali metal phenoxides with C02 followed a similar ground mechanism that comprised three intermediates and three transition states. In step 1, C02 must first be activated by an alkali metal phenoxide. In the case of the sodium phenoxide [24a], C02 can only attack at the polarized O-Na bond to form a Ph0Na/C02 complex as the first intermediate (structure 4). The calculation definitely rules out a direct C-C bond formation at the aromatic ring. 

Each bimetallic specimen thus obtained was cut into two pieces using an electric-spark machine. The surface of the Ni-Bi couples was first ground mechanically and then polished electrolytically using an Elypovist ...
