مبدل های کاهش کلیدیافته با توجه به مزایای متعدد از جمله هزینه و وزن کم، اندازه کوچک مورد توجه قرار گرفته اند. تاکنون ساختارهای مختلفی در جهت کاهش تعداد کلیدهای مبدل های قدرت در مقالات ارائه شده که می توان آن ها را به دو دسته اینورترهای تک خروجی و اینورترهای چندخروجی دسته بندی کرد. در این مقاله سه ساختار مبتنی بر مبدل های کاهش کلیدیافته بر اساس مبدل های 15 کلیدی 3 ساق و 15 کلیدی 5 ساق و 12 کلیدی...
The products obtained by forcing the reaction with nucleosides (guanosine, Guo, and adenosine, Ado) of potential anticancer drugs for nongenomic targets [PtCl(O,O'-acac)(L)] (L = dimethyl sulfoxide, DMSO; dimethyl sulfide, DMS), closely related to their very powerful organometallic analogues [Pt(O,O'-acac)(γ-acac)(L)], have been studied. [PtCl(O,O'-acac)(L)] and [Pt(O,O'-acac)(γ-acac)(L)] compl...
Dinuclear Ru(III) complexes, [Ru(III)(acac)(2)(dabe)Ru(III)(acac)(2)] (acacH = acetylacetone; dabeH(2) = 1, 2-diacetyl-1,2-dibenzoylethane) and [Ru(III)(acac)(2)(tbet)Ru(III)(acac)(2)] (tbetH(2) = 1,1,2,2-tetrabenzoylethane) were synthesized by reacting [Ru(acac)(2)(CH(3)CN)(2)]PF(6) with dabeH(2) and tbetH(2) respectively, in toluene. The X-ray structural analysis of a meso-type dinuclear Ru(I...
During starvation ketone bodies, acetoacetate (AcAc), 3-hydroxybntyrate (fl-OHB) and acetone accumulate in the body fluids. AcAc and /3-OHB are synthesized in the liver primarily from the partial oxidation of long-chain fatty acids. They are released into the blood as short-chain fatty acids, dissociate to become water-soluble anions and are distributed at different concentrations in the water ...
The acidic group (-CO2H) of MultiWall Carbon Nanotube (MWCNT) converted to acyl chloride group (-COCl) producing of MVCNT@COCl. Then the reaction of MVCNT@COCl and MoO2(acac)2 resulted in direct immobilization of the MoO2(acac)2 and the formation of MVCNT@CO(acac)MoO2(acac) catalyst. In addition, the MVCNT@COCl was esterified...
By introducing a phenyl substituent into the meta-site of the phenyl segment of the 2-phenylbenzothiazole ligand, two novel orange iridium(III) complexes, namely, (3Phbt)2Ir(acac) and (3OMePhbt)2Ir(acac), have been synthesized. Compared with their parent compound (bt)2Ir(acac), both of them possess much enhanced thermostability and film amorphism, making them suitable candidates as guests for h...
Pt(acac)2, AgNO3, Cu(acac)2, Fe(acac)2, Pd(acac)2, RhCl3, Co(acac)2 poly(vinylpyrrolidone) (PVP; Mw 8000), were purchased from Alfa Aesar Co.Ltd, and Bi(NO3)2, KI, KBr, KCl, tris (hydroxymethyl ) aminomethane, HCHO solution (37 wt%), formamide, and acetone were purchased from Sinopharm Chemical Reagent Co. Ltd . All the chemicals were analytical grade and used as received without any purificati...
An unusual heterobimetallic volatile compound [Pb2Co5(acac)14] was synthesized by the gas phase/solid-state technique. The preparation can be readily scaled up using solution approach. X-ray powder diffraction, ICP-OES analysis, and DART mass spectrometry were engaged to confirm composition purity of complex. is unique among large family lead(tin): transition metal = 2:1, 1:1, 1:2 β-diketonates...
