High-Yield Synthesis of Silver Nanoparticles by Precipitation in a High-Aqueous Phase Content Reverse Microemulsion

Chitosan-coated magnetic nanoparticles prepared in one-step by precipitation in a high-aqueous phase content reverse microemulsion.

Chitosan-coated magnetic nanoparticles (CMNP) were prepared in one-step by precipitation in a high-aqueous phase content reverse microemulsion in the presence of chitosan. The high-aqueous phase concentration led to productivities close to 0.49 g CMNP/100 g microemulsion; much higher than those characteristic of precipitation in reverse microemulsions for preparing magnetic nanoparticles. The o...

Synthesis of Iron Yttrium Garnet Nanoparticles by Reverse Microemulsion Method

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...

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...

A Simple and High Yield Solvothermal Synthesis of Uniform Silver Nanowires with Controllable Diameters

Silver nanowires were synthesized by solvothermal method through reducing silver nitrate (AgNO3) with ethylene glycol (EG) in the presence of polyvinylpyrrolidone (PVP). In order to prevent the agglomeration of Ag+ in the initial Ag seeds formation, sodium chloride (NaCl) was added into the solution to form AgCl colloids. By dissolving AgCl in the late stages, Ag+ ions were released into the so...
