Z Jia et al.
Electrophoresis, 22(6), 1112-1118 (2001-05-19)
A fast screening method for the determination of the dissociation constants (pKa) of acidic, basic, and multivalent compounds was developed by using pressure-assisted capillary electrophoresis (PACE). External air pressure was applied to shorten the analysis time. The separation efficiency decreases
Toni Ann Riveros et al.
Electrophoresis, 30(13), 2385-2389 (2009-07-22)
The successful application of artificial neural networks toward the prediction of product distribution in electrophoretically mediated microanalysis is presented. To illustrate this concept, we examined the factors and levels required for optimization of reaction conditions for the conversion of nicotinamide
Ting Li et al.
The Analyst, 137(20), 4766-4773 (2012-08-25)
Capillary electrophoresis (CE) is not only an effective separation technique, but can also serve as a sample preparation tool for enrichment and purification at sub-microliter sample volumes. Our approach is based on the use of a discontinuous buffer system consisting

The Journal of organic chemistry, 71(4), 1668-1676 (2006-02-14)
The mechanism of the formation of substituted quinolines from anilines and alpha,beta-unsaturated ketones has been studied by the use of 13C-labeled ketones in cross-over experiments. In the reaction of doubly labeled 13C(2,4) mesityl oxide, a 100% scrambling of the label
