The electrocatalytic activities of Mn₃O₄/C composites are studied in lithium-oxygen (Li-O₂) batteries as cathode catalysts. The Mn₃O₄/C composites are fabricated using ultrasonic spray pyrolysis (USP) with organic surfactants as the carbon sources. The physical and electrochemical performance of the composites is characterized by X-ray diffraction, scanning electron microscopy, particle size an...

A simple and accurate cloud point-spectrophotometric method for determination of Mesalazine (MEZ) in pure form pharmaceutical formulations is proposed. The procedure based on the reaction with brilliant green dye (BG) forming a pale-yellow ion-pair complex after extracting Triton X-114 measured at 361 nm. experimental conditions phase separation were optimized. Beer’s law was obeyed range 0.3-3...

The deduced sequences of the Omp10, Omp16, and Omp19 outer membrane proteins of Brucella spp. contain a potential bacterial lipoprotein processing sequence. After extraction with Triton X-114, these three proteins partitioned into the detergent phase. Processing of the three proteins is inhibited by globomycin, a specific inhibitor of lipoprotein signal peptidase. The three proteins were radioi...
