addiction to drugs, such as heroin, cocaine and alcohol, exacts great human and financial costs on society. various evidence-based pharmacological and psychosocial interventions are currently used in the treatment of drug addiction but they do not produce adequate therapeutic benefits in every patient. further, barriers such as financial cost, lack of availability, or perceptions of existing tr...

A tube type mini electrode has been made to detect paracetamol levels in herbal medicine, the is of a glass with diameter 0.7 cm, length 3 cm. As membrane mixture chitosan, activated carbon from rice husk, and cetyl trimethyl ammonium (CTA)-paracetamol. The internal solution standard 0.01 M phosphoric acid pH 2. average sensitivity sensor (22.60 ± 0.01) mV/decade linear concentration range 10-6...

Magnetic nanoparticles of cobalt ferrite (CoFe204) have been synthesized using water-in-oil microemulsions consisting of water, cetyl trimethyl ammonium bromide (surfactant), n-butanol (cosurfactant), and n-octane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and these were then separated and calcined to give the magnetic oxide. X-ray diffract...

Redox behavior of midazolam was studied at a glassy carbon electrode in various buffer systems, supporting electrolytes and pH using differential pulse, square-wave and cyclic voltammetry. Based on its reduction behavior, a direct differential pulse voltammetric method has been developed and validated for the determination of midazolam in parenteral dosage. Three well-defined peaks were observe...

The aim of this study was to synthesize by high shear homogenization method and to characterize new solid lipid nanoparticles loaded with green tea extract, nanoparticles which show high antioxidant activity. In this respect, cetyl palmitate and glyceryl stearate were used as solid lipids in combination with two nonionic surfactants, Tween20 and Tween80 and an ionic surfactant as lecithin. The ...

Nitrogen and metal doped nanocarbons derived from polyaniline (PANI) have been widely explored as electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells. In this work, we report surfactant-template synthesis of PANI nanostructures and the ORR electrocatalysts derived from them. By using cationic surfactant such as the cetyl trimethyl ammonium bromide (CTAB) as the template and t...
