CHIRAL STATIONARY PHASES USED FOR ENANTIOMERIC RESOLUTION
Middle East Journal of Science, 2015 Enantiomer separation has attracted increasing attentions in pharmaceutical industry, due to great differences in pharmacological, toxicological and/or metabolic activities of enantiomeric drugs in living system. Several methods have been succesfully used to achieve chiral separation.

Consistent histories for tunneling molecules subject to collisional decoherence
, 2012 The decoherence of a two-state tunneling molecule, such as a chiral molecule or ammonia, due to collisions with a buffer gas is analyzed in terms of a succession of quantum states of the molecule satisfying the conditions for a consistent family of ...

Curvature and topological effects on dynamical symmetry breaking in a four- and eight-fermion interaction model [PDF]
, 2010 A dynamical mechanism for symmetry breaking is investigated under the circumstances with the finite curvature, finite size and non-trivial topology. A four- and eight-fermion interaction model is considered as a prototype model which induces symmetry ...

Absence of Landau-Peierls Instability in the Magnetic Dual Chiral Density Wave Phase of Dense QCD [PDF]
, 2020 We investigate the stability of the Magnetic Dual Chiral Density Wave (MDCDW) phase of cold and dense QCD against collective low-energy fluctuations of the order parameter.

Aldol Reactions of Axially Chiral 5-Methyl-2-(o-aryl)imino-3-(o-aryl)-thiazolidine-4-ones
Molecules, 2016 Axially chiral 5-methyl-2-(o-aryl)imino-3-(o-aryl)-thiazolidine-4-ones have been subjected to aldol reactions with benzaldehyde to produce secondary carbinols which have been found to be separable by HPLC on a chiral stationary phase.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
Advanced Materials, EarlyView.An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

, 2012 We consider the O(N) linear {\sigma} model and introduce an auxiliary field to eliminate the scalar self-interaction. Using a suitable limiting process this model can be continuously transformed into the nonlinear version of the O(N) model.
