“…The widespread interest in nonlinear optical crystalline materials has been motivated by their potential use in the fabrication of all-optical photonic devices [1][2][3][4][5][6]. Transparent crystalline materials can exhibit different kinds of optical nonlinearities which are associated with nonlinear polarization.…”

Calcium Tartrate crystals were synthesized using sol-gel technique. Linear optical studies of the crystals were carried out in the UV-Vis-NIR spectral range. Nonlinear optical open aperture z-scan studies were done using high sensitive z-scan experimental technique. Both saturable absorption and reverse saturable absorption behaviour were observed at different input fluences. Reverse saturable absorption characteristic of the crystals make them suitable for optical limiting applications. Our analysis revealed that the novel crystal has the optimum values for the optical limiting parameters which are required for a high-performance optical limiter.

“…To better understand the role of structural and thermodynamic factors for preferential crystallization of equimolar mixtures of enantiomers, we have undertaken a high-pressure study of NaTa·H 2 O. The structures of enantiomers d -NaTa·H 2 O and l -NaTa·H 2 O , as well as racemate dl -NaTa·H 2 O polymorphs α and β , were determined by X-rays. Under normal conditions, the enantiomorph (orthorhombic space group P 2 1 2 1 2 1 ; D x = 1.892 g cm –3 ) is by 1.5% more dense than racemate α- dl -NaTa·H 2 O (monoclinic space group P 2 1 / c ; D x = 1.864 g cm –3 ) and by 1.0% more dense than polymorph β- dl -NaTa·H 2 O (triclinic space group P 1̅; D x = 1.873 g cm –3 ).…”

High-pressure recrystallization could be the cheapest clean method of resolving enantiomers from the racemates defying Wallach's rule. We have investigated the effect of pressure on sodium tartrate monohydrate (NaTa•H 2 O), a notorious exception from Wallach's rule: both racemic polymorphs α-DL-NaTa•H 2 O and β-DL-NaTa•H 2 O are less dense than the enantiomers. According to the mobile-equilibrium principle, such high-density enantiomorphs should spontaneously separate under high pressures. The pressure dependence of the Gibbs free energy explains the preferential crystallization of mixed enantiomers of NaTa•H 2 O.
