The optical spectrum band positions and EPR parameters (g factors g//, g⊥ and hyperfine structure constants A// and A⊥) for VO 2+ ions in zinc potassium phosphate hexahydrate are theoretically studied from the complete diagonalization (of energy matrix) method (CDM). In the calculation, the contributions to the EPR parameters from the s-and p-orbitals as well as the spin-orbit coupling coeffici...
Aim. Strontium salts are effective and selective anti-irritants for chemically induced sensory irritation associated with stinging, burning, or itching. The aim of the present study was to determine the cytotoxic and/or proliferative effects of strontium chloride on fibroblast cell culture. Method. A mouse connective tissue fibroblast cell line, L929 (ATCC cell line, NCTC clone 929) was culture...
Cerium was separated from the light rare earths by ignition of the nitrates whereby the cerous nitrate was decomposed to eerie oxide. Small scale investigations were made using sodium nitrate and magnesium nitrate hexahydrate as fluxes. A cost estimate based on data from the small scale investigations showed the sodium nitrate ignition to be more economical; therefore, bench scale investigation...
A new complex [Mg(L)₂(phen)(H₂O)₂](phen)(H₂O)₂ [L= N-benzenesulphonyl-L-leucine] was synthesized by the reaction of magnesium chloride hexahydrate with N-benzenesulphonyl-L-leucine and 1,10-phenanthroline in the CH₃CH₂OH/H₂O (v:v = 5:1). It was characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the title complex [Mg(L)₂(phen)(H₂O)₂](phen)(H₂O)₂...
The structure of highly twinned pinacol (2,3-dimethyl-2,3-butanediol) monohydrate, the existence of which has been known since 1922, has been determined, and the structures of anhydrous pinacol and its two other known hydrates have been reinvestigated. All the phases are unusual. The anhydrous phase is exceptional among molecular crystals in having molecules located on three different symmetry ...
