The Role Seemingly of Amorphous Silica Gel Layers in Chiral Separations by Planar Chromatography [PDF]
Pakistan Journal of Analytical & Environmental Chemistry, 2007 In planar chromatography, silica gel appears as the most frequently used adsorbent. Its preference as planar chromatographic stationary phase is due to its high specific surface area (ca.

Determination of the Very High Barriers to Conformational Processes by the Neat Racemization Technique. Part 1: Barriers to Ring Inversion in Dibenzo [a,c] Dinaphtho [2,3-e; 2,3-g] Cyclooctatetraene and Hindered Rotation in 2,2'-Dimethyl Binaphthyl [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1996 A method is described by which it is possible to determine the high barrier to ring inversion and hindered rotation by neat racemization of optically active compounds when the racemization is caused by ring inversion or hindered rotation.

A Stern-Gerlach separator of chiral enantiomers based on the Casimir-Polder potential
, 2018 We propose a method to separate enantiomers using parity violation in the Casimir-Polder potential between chiral mirrors and chiral molecules. The proposed setup involves a molecular beam composed of chiral molecules passing through a planar cavity ...
