Stibnite (Sb2S3) semiconducting material was successfully synthesized by a rapid and facile microwave route using antimony chloride (SbCl3) and sodiumthiosulfate (Na2S2O3) dissolved in propylene glycol (PG) containing different hydroxyethyl cellulose (HEC) masses. The phase identification, morphology, and elemental composition of products were characterized by X-ray diffraction (XRD), transmiss...
در سال های اخیر، آنتیموان تری کلرید (sbcl3) به عنوان یک کاتالیزور اسید لوییس کارآمد در انتقالات مختلف آلی استفاده می شود. در این پروژه ما قصد داریم یک روش آسان و کارآمد برای آماده سازی مشتقات 3،2-دی هیدروکینازولین-4-(h1)-اون از تراکم ترکیبات کربونیل دار با 2-آمینوبنزآمید به وسیله ی کاتالیزور sbcl3 گزارش کنیم. این واکنش تراکمی به وسیله تعیین درصد مولی sbcl3 در متانول و دمای اتاق بهینه شد و مشتقا...
The measurement by visual methods of the fleeting blue colour of vitamin A in the antimony-trichloride reaction presents considerable difficulties which can be largely overcome by the use of photoelectric methods with corresponding increase in accuracy. The photoelectric spectrophotometer now described was constructed in I 941 when no comparable instrument of this type was commercially availabl...
Our previous study showed that chromium malate improved the regulation of blood glucose in mice with alloxan-induced diabetes. The present study was designed to evaluate the effect of chromium malate on glycometabolism, glycometabolism-related enzymes and lipid metabolism in type 2 diabetic rats. Our results showed that fasting blood glucose, serum insulin level, insulin resistance index and C-...
A hyperresponsive tool to assess supramolecular catalysis, the cyclization of di-epoxides into cyclic ethers is used elucidate difference between pnictogen-bonding and Lewis acid catalysis systematically. For all stereoisomers, most tested catalysts follow Baldwin rules. Brønsted anion–? afford almost only products. acids such as SbCl3, BF3 BiCl3 give poorest selectivity, with at least 50 % (B)...
The effect of gold trichloride on DNA synthesis of human thymocytes and peripheral blood lymphocytes was tested. A stimulation was obtained in both cell types with a concentration of 6-50 micrograms/ml. Gold trichloride may thus not be used in a lymphocyte transformation test for the diagnosis of contact allergy.
