A simple and sensitive colorimetric gold nanoparticle probe for detection of melamine in infant formula was developed by the reduction of Au(III) salt with sodium citrate. This method is rather simple that does not involve any surface modification of the nanoparticles or multistep sample treatment. This technique is based on the fact that the optical properties of gold nanoparticles depend on d...

This study focuses on the degradation of phenol in aqueous solutions using photolysis and sonolysis methods. It investigates impact catalyst mass, types light (UV-A, UV-C, visible light), (RHAC, TiO2, TiO2/RHAC), processing time degradation. The are analyzed before after Spectrophotometer UV-Vis HPLC. research aims to understand factors influencing provide a basis for further studies enhance ef...

vanadium supported on highly ordered nanoporous silica (vox-lus-1) was synthesized and characterized by xrd, nitrogen adsorption‑desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...

In the present work, monolithic matrix transdermal systems containing Drug x were prepared using various ratios of the polymer blends of hydroxy propyl methyl cellulose (HPMC) and Eudragit S 100 (ES) with triethyl citrate as a plasticizer. A 32 full factorial design was employed. The concentration of HPMC and ES were used as independent variables, while percentage drug release was selected as d...

Background and Objectives: The instructions of the manufacturer showed that metronidazole infusion solution (5mg/mL) is incompatible with few drugs. This study aimed to determine the physical and chemical compatibilities of metronidazole infusion with commonly used intravenously administered physiological solutions. Methods: Metronidazole injection in a commercially available concentration of 5...
