Recycling sodium dichromate in sodium chlorate crystallization mother liquor by nanofiltration membrane

Enantiomorphic symmetry breaking in crystallization of molten sodium chlorate.

Enantiomorphic symmetry breaking of stirred samples of molten sodium chlorate is demonstrated, revealing the unexpected involvement of an achiral solid phase. The results should stimulate future computational models of nucleation, including symmetry breaking, and have implications for mechanisms that invoke enantiomorphism in natural minerals to explain biohomochirality.

Kinetics and disposition of orally dosed sodium chlorate in sheep.

Experiments were conducted in sheep to determine excretory characteristics of sodium chlorate after a single oral dose. In Exp. 1, lambs (n = 16; age = 8.1 ± 1.7 d; BW = 8.2 ± 1.1 kg; mean ± SD) were dosed orally with 0, 30, 60, or 90 mg/kg BW of sodium chlorate. Twenty-four hours after exposure chlorate residues were dose dependent (P < 0.05) in small intestinal contents, serum, and urine, but...

Enantioselective Crystallization of Sodium Chlorate in the Presence of Racemic Hydrophobic Amino Acids and Static Magnetic Fields

We study the bias induced by a weak (200 mT) external magnetic field on the preferred handedness of sodium chlorate crystals obtained by slow evaporation at ambient conditions of its saturated saline solution with 20 ppm of added racemic (DL) hydrophobic amino acids. By applying the Fisher test to pairs of experiments with opposing magnetic field orientation we conclude, with a confidence level...

Mercury’s sodium exosphere: Magnetospheric ion recycling

[1] A three-dimensional Monte Carlo model of Mercury’s neutral sodium exosphere was used to describe correlation between the observed variations in the exospheric density and the variations in the surface concentration of sodium along Mercury’s motion around the Sun [Leblanc and Johnson, 2003]. Four processes of ejection were taken into account: thermal and photon stimulated desorptions, solar ...
