Despite the low cost and high ionic conductivity of aqueous electrolytes, their practical applications are limited because a withstand voltage 1.2 V The energy density increases in proportion to which is crucial factor for electric double-layer capacitors (EDLCs) with solid polymer electrolytes. In this study, electrolyte solution was made into viscous improve electrolyte. prepared from sodium ...

The present work aims to study the influence of some physicochemical parameters (light, temperature, ethanol, bile salts, potassium hydroxide, hydrogen peroxide) on content Metronidazole (MTZ) contained in reference substance (SR) and a pharmaceutical specialty Flagyl® 250 mg tablet (FLG). method developed was linear accurate accordance with USP 38 MTZ contents were obtained by UV-visible spect...

Procedure 1. Place the specimen on a clean glass slide. Add 1 drop of 20% KOH. 2. Place the cover glass on top of the slide and gently press to get rid of any air bubbles. Blot excess solution from the finished slide preparation with the gauze. 3. Place slide on the microscope stage and start with a low-power (10 ×) examination. To make epithelial cells visible, reduce illumination by lowering ...

Zeolitization of fly-ash by a direct route and a fusion method (two-step process) was studied using an orthogonal array of Taguchi experimental design. The effect of different processing conditions, such as type and concentration of the mineralizing agent, fusion and crystallizing temperatures and times and stirring speed, on the quantity of the zeolitic phase obtained, were evaluated. By means...

Animals. Male rats (230-270g.) of the Wistar albino strain were supplied by the Animal Department, University of Otago Medical School. Enzymes and cofactors. Alcohol dehydrogenase, lactate dehydrogenase and malate dehydrogenase (analytical reagent grade) were obtained from C. F. Boehringer und Soehne G.m.b.H., Mannheim, Germany; glucose 6phosphate dehydrogenase, NADI, NADH, NADP+, NADPH and cyt...

The main target of this study was to eliminate gas-phase toluene with activated carbon from indoor air. carbons were prepared Robinia pseudoacacia L. biomass under different conditions. change in surface functional groups the produced raw material and by pyrolysis absence oxygen at 500–900 °C, activation potassium hydroxide (KOH). highest area 1271.3 m2/g which gives reason for its external por...

This work evaluates the effect of sodium meta-silicate pentahydrate (SMS) and potassium hydroxide concentrations on properties Al2O3-TiO2 coatings produced through plasma electrolytic oxidation in a solution containing 3 g L?1 titanyl oxalate, (PTO), using unipolar waveform with constant current density. The surface cross-section characteristics PEO including morphology, elemental distribution,...

Oil palm shell was used as a precursor for preparation of activated carbon using different chemical activations (potassium hydroxide (KOH), zinc chloride (ZNCl2), and phosphoric acid (H3PO4)). Each carbons (AC) mixed with nano-zinc oxide to form composite. From the gas sorption analyzer, it is showed that nitrogen adsorption isotherms show Type II ZnO/AC-KOH ZnO/AC-ZnCl2 corresponding micro- me...
