synthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Magnetized microdischarge plasma generation at low pressure
A magnetized microdischarge plasma is generated at low pressure with planar electrodes and a non-uniform magnetic field configuration causing closed E×B electron drift. Stable generation with a 1 mm electrode gap has been achieved in 0.5–55 Torr of argon. The breakdown voltage curve is found to have two local minima, the lower of which is believed to be caused by strong electron magnetization, ...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولModelling of microdischarge devices: plasma and gas dynamics
Microdischarge devices (MDs) share many properties with their macroscopic counterparts while having unique features resulting from their ability to sustain large current densities and power depositions on a continuous basis at pressures approaching atmospheric. The dynamics of cylindrical, metal–dielectric–metal sandwich MDs sustained in Ar having characteristic sizes of a few hundred micrometr...
متن کاملSynthesis and antimicrobial properties of nanosilver
Nanosilver (nAg) was prepared via Tollens method using dextrin as stabilizer. The morphology, size distribution and average size of the obtained nAg were characterized using Transmission electron microscope (TEM) and Dynamic light scattering (DLS) technique. A kinetic study of toxicity of nAg on Escherichia coli (E. coli) was determined. The obtained results showed that nAg exhibits spheric sha...
