Controllable synthesis of uniform spherical silver nanoparticles was investigated by carrying out a chemical reduction reaction in a micro emulsion, formed under high shear mixing of aqueous silver nitrate solution and 2-ethyl hexanol as organic phase. Sodium borohydride was used as reducing agent and sorbitan monooleate (span-80) as stabilizer. Further, a study has been performed to observe th...

according to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of cu, ag, au, pb and se. in this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. silver was separated from anode slime by using of hno3 and hcl. x-ray fluorescence spectroscopy (xrf) was used to characterize anode sl...

A green synthesis of silver nanoparticles was done using a particular plant extract of Limonia acidissima. Silver nanoparticles were synthesised by the bioreduction of silver nitrate using different concentrations of plant extract, and UV–visible spectral analysis was carried out to confirm the formation of silver nanoparticles. The presence of various phytochemicals like flavonoids, steroids, ...

Powders of silver sulfide have been synthesized by chemical bath deposition from aqueous solutions of silver nitrate and sodium sulfide in the presence of sodium citrate or EDTA-H2Na2. Colloid solutions have been prepared by a chemical condensation method from the same aqueous solutions. Synthesized silver sulfide nanopowders have a monoclinic (space group P21/c) acanthite-type structure but th...

Aim: To identify the compound accountable for the high reducing power lining the surface of the corneal epithelium. Materials and methods: Chinoy’s histochemical method was used to demonstrate the occurrence of a high reducing agent on the corneal surface. Ascorbic and uric acid concentration in the tear and cornea were determined by highpressure liquid chromatography using a μ-Bondapak-NH 2 co...
