conventional slow evaporation and sankaranarayanan ramasamy sr method grown diglycine Zinc Chloride dgzc single crystal and its comparative study
Journal of Crystal Growth, 2010Co-Authors: Senthil M Pandian, P. RamasamyAbstract:Abstract Diglycine Zinc Chloride, a semi-organic nonlinear optical crystal was grown by conventional slow evaporation and Sankaranarayanan–Ramasamy method. By employing this unidirectional method, diglycine Zinc Chloride single crystals of diameters 10, 30 and length up to 60 mm were grown. The growth conditions have been optimized. A maximum growth rate of 1.5 mm per day was realized. A comparative damage threshold analysis made on the diglycine Zinc Chloride crystals by conventional and unidirectional method shows that the crystal grown by Sankaranarayanan–Ramasamy method has higher damage threshold. The conventional and Sankaranarayanan–Ramasamy method grown diglycine Zinc Chloride crystals were also characterized by chemical etching, UV–vis analysis, dielectric constant, dielectric loss, Vicker’s microhardness analysis and the results were compared. The present study indicates that the crystal quality of Sankaranarayanan–Ramasamy method grown diglycine Zinc Chloride is good compared to conventional slow evaporation method grown crystal.

Acute Zinc Chloride Ingestion in a Child: Local and Systemic Effects
Annals of Emergency Medicine, 1994Co-Authors: Patrick E. Mckinney, Jeffrey Brent, Ken KuligAbstract:Abstract A 16-month-old boy ingested liquid Zinc Chloride/ammonium Chloride soldering flux. He developed severe local burns, metabolic acidosis, hepatic damage, hyperamylasemia, lethargy, and hypertension. Peak measured plasma Zinc was 1,199 μg/dL. Because of persistent signs of systemic toxicity, he was chelated with dimercaprol (BAL) and EDTA. Although clinical improvement was noted coincident with the initiation of chelation, there was no apparent increase in urinary Zinc excretion. Scarring in the gastric antrum necessitated an antrectomy. The child recovered without other apparent complications.
