The title salts, which are formed by the action of dimethylcyanamide on the phosphorus oxychloride complexes of a variety of tertiary amides, are useful precursors of six-membered heteroaromatic compounds: they react with simple amidines to yield 1,3,5-triazines and with N,N-dimethylamidines to give pyrimidines; 3-arylmethyl-1-chloro-1,3-bis(dimethylamino)-2-azapropenylium perchlorates form isoquinolines
This invention relates to novel (Z,Z), (Z,E) and (E,Z) olefin isomers of substituted benzylidene cycloketones and their pharmaceutically acceptable salts. The compounds of the invention are potent factor Xa inhibitors thereby acting as anticoagulants useful in a number of thrombotic disease states. Pharmaceutical compositions are proposed for the compounds.
Novel magnetic Fe<sub>3</sub>O<sub>4</sub>@rGO@ZnO onion-like microspheres decorated with Ag nanoparticles for the efficient photocatalytic oxidation of metformin: toxicity evaluation and insights into the mechanisms
and Ag NPs were loaded on the surface of the catalyst. As compared to plain ZnO, the as-made FGZAg catalyst significantly enhanced the photocatalyticactivity toward MTF degradation under visible-light irradiation. The complete degradation and 60% mineralization of 20 mg L−1 MTF was achieved with FGZAg within 60 min in the visible-lightphotocatalytic process. The interaction between rGO and Ag NPs
包括药物和个人护理产品在内的新兴水污染物已成为水污染的主要关注点,并且已经进行了一些努力来有效去除这些污染物。为了解决这个问题,本研究报告了一种新型的纳米结构混合洋葱状球形催化剂Fe 3 O 4 @ rGO @ ZnO / Ag-NPs(FGZAg)的合成,并研究了其在两种紫外线下的降解二甲双胍(MTF)的能力。 -和可见光照射。使用功能化的Fe 3 O 4微球作为模板制备催化剂,依次涂覆氧化石墨烯和ZnO壳,然后进行Ag纳米颗粒(NP)装饰,最后将其在N 2下退火大气层。使用XRD,N 2吸附-解吸,SEM,HRTEM,UV-vis吸收光谱,FTIR光谱,拉曼光谱,VSM,XPS,EIS和PL测量对制备的样品进行表征。结果表明,所制备的具有六方纤锌矿晶体结构的洋葱状球具有中孔结构,并且Ag NPs负载在催化剂表面上。与普通的ZnO相比,制成的FGZAg催化剂在可见光照射下显着增强了对MTF降解的光催化活性。20

In this work, the construction of Co3O4 two dimensional (2D) nano-assemblies utilizing infinitecoordinationpolymers (ICPs) as precursors was investigated, aiming at the morphology targeted fabrication and utilization of 2D materials. Based on the successful modulation of morphology, a rose-like Co based ICP precursor was obtained, which was further transformed into porous Co3O4 nanoflake assemblies
