Synthesis of nano-nickel by a wet chemical reduction method in the presence of surfactant (SDS) and a polymer (PVP)

Nano-sized nickel particles have been synthesized by a bottom-up approach, using hydrazine as the reducing agent in the presence of an anionic surfactant - sodium-dodecyl sulphate (SDS). The effect of adding a cationic polymer -polyvinylpyrrolidone (PVP) with an anionic surfactant has been studied at two different temperatures; the rate of reduction increased as the reaction temperature was increased from 60 to...

Kinetics study of fibrinogen adsorbed on titanium powder

A kinetics study of fibrinogen adsorbed on titanium has been investigated by means of spectrophotometer of the type developed for micro-enzyme linked immune-sorbent assay determination. Implants invoke inflammatory responses from the body and an attempt to alleviate the problem caused by the adsorption of protein on artificial implants mostly used in the medical, informed this study. The experimental isotherm data were...

A study on the anticancer activities of ethanolic curcumin extract

In Iraq like most third world countries, attempts to extract, identify and study the anticancer activity of the active components of plants and use it as drugs. Curcumin[(1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5dione] is the major yellow pigment extracted from turmeric, a commonly used spice, derived from the rhizome of the plant Curcuma longa. In India and Southeast Asia, turmeric has long been...
