标题 :A method for synthesis of metal halide perovskite (cspbbr3) nano/microcrystals
发明人：M A GOKUL; RAHMAN ATIKUR

摘要:The present invention relates to metal halide perovskite (CsPbBr3) nano/microcrystals. Specifically, the present invention relates to a method for the synthesis of metal halide perovskite (CsPbBr3) nano/microcrystals. The present invention uses an easy, scalable low temperature growth of metal halide nanoparticles like CsPbBr3. The method uses a clever play on the solubility and ion exchange mechanism to precipitate nano and microcrystals of metal halide perovskites. The synthesis resulted in stable perovskite crystals with high photo- luminescence, ultralow dark current and control over their morphology. The combination of ultralow dark current, high responsivity, exceptional detectivity, and broad-band photon detection capabilities makes these crystals an excellent choice for upcoming sensors and detector technologies.

标题 :Synthesis of the Micro-Porous Silica Gel and Its Application to the Preparation of Catalysts for C2 Oxygenates Synthesis from Syngas

摘要:A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C 2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl 3 or Rh(NO 3 ) 3 . The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts. The obtained catalysts show high activity and selectivity in the synthesis of C 2 -oxygenates by the hydrogenation of CO under mild process conditions.

标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER
权利人:UNIV HOWARD
摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.

摘要:The present invention relates to a novel synthesis method for acyl-pantetheine derivatives. The present invention further relates to the use of said synthesized acyl-pantetheine derivatives as a starting material in the enzymatic synthesis of acyl-coenzyme A derivatives. According to a first aspect thereof, the present invention provides a method for the synthesis of acyl-pantetheine derivatives, the method including the steps of: a) providing a source of pantetheine; b) providing a source of acyl ester; and c) contacting the source of pantetheine with the source of acyl ester to form the corresponding acyl-pantetheine derivative, having the general formula (I), wherein R is an acyl group.The present invention also provides a method for the synthesis of acyl-coenzyme A derivatives as well as the use of a source of pantetheine and a source of acyl ester in the preparation steps of these two methods.
