Water and organic content tuning of mobile phase for Enantioseparation of fungicides by capillary electrochromatography using cellulose Tris(3‑chloro-4-methylphenylcarbamate) based stationary phase

open access: yesJournal of Chromatography Open
This study investigated the effect of mobile phase composition, especially water content in a mixture of protic and non-protic organic solvents, on chiral recognition and separation efficiency using a cellulose tris(3‑chloro-4-methylphenylcarbamate ...

Single-run reversed-phase HPLC method for determining sertraline content, enantiomeric purity, and related substances in drug substance and finished product

open access: yesJournal of Pharmaceutical Analysis, 2020
A direct enantio-, diastereo-, and chemo-selective high-performance liquid chromatographic method was developed for determining the content, enantiomeric purity, and related substances of the chiral antidepressant drug sertraline HCl in a single ...

Porous Organic Cage-Embedded C10-Modified Silica as HPLC Stationary Phase and Its Multiple Separation Functions

open access: yesMolecules, 2022
Reduced imine cage (RCC3) was covalently bonded to the surface of silica spheres, and then the secondary amine group of the molecular cage was embedded in non-polar C10 for modification to prepare a novel RCC3-C10@silica HPLC stationary phase with ...

Spontaneous symmetry breaking and inversion-line spectroscopy in gas mixtures

open access: yes, 2015
According to quantum mechanics chiral molecules, that is molecules that rotate the polarization of light, should not exist. The simplest molecules which can be chiral have four or more atoms with two arrangements of minimal potential energy that are ...

Temporary mirror symmetry breaking and chiral excursions in open and closed systems [PDF]

open access: yes, 2011
The reversible Frank model is capable of amplifying the initial small statistical deviations from the idealized racemic composition. This temporary amplification can be interpreted as a chiral excursion in a dynamic phase space.

Quarkyonic matter in lattice QCD at strong coupling

open access: yes, 2009
We study the phase diagram of quark matter at finite temperature and density in the strong coupling lattice QCD with one species of unrooted staggered fermions including finite coupling ($1/g^2$) effects for color SU($N_c$).

Towards a holographic quark-hadron continuity

open access: yes, 2019
We study dense nuclear and quark matter within a single microscopic approach, namely the holographic Sakai-Sugimoto model. Nuclear matter is described via instantons in the bulk, and we show that instanton interactions are crucial for a continuous ...

Light Quark Masses in Multi-Quark Interactions [PDF]

open access: yes, 2013
We suggest and discuss in detail a multi-quark three flavor Lagrangian of the Nambu -- Jona-Lasinio type, which includes a set of effective interactions proportional to the current quark masses.
