Abstract Electrochemical dissolution of pressed into discs and sintered metallic molybdenum powder with the mass 712 ± 10 mg ( n = 15) in potassium hydroxide solution was studied detail. The technique considered to apply for irradiated 100 Mo target 99m Tc production. effect various parameters, e.g., concentration electrolyte solution, temperature, current density, surface area platinum cathode...

BACKGROUND Although molluscum contagiosum (MC) resolves spontaneously, there are several reasons to treat this dermatological disorder. OBJECTIVE To evaluate the safety and efficacy of 5% imiquimod cream versus 10% potassium hydroxide (KOH) solution in treating MC, and to propose the mechanism of cure by observing the histological findings. METHODS Imiquimod or KOH were applied by the patie...

Nitrogen dioxide is formed during delivery of inhaled nitric oxide for the treatment of patients with pulmonary hypertension. Soda lime has been shown to absorb nitrogen dioxide. We tested three different commercially available soda lime preparations (Sodasorb, Drägersorb 800 and Sofnolime) for their efficacy in absorbing nitrogen dioxide and nitric oxide during simulated nitric oxide inhalatio...

Corrosion reliability of hearing aid (HA) devices is a critical issue due to their exposure harsh climatic conditions like high humidity and temperature, along with the combination level salt contamination from human sweat environmental pollutants. Statistical analysis corrosion failure data can provide better understanding sequence cause, which important as multiple parameter effects on comple...

Optimal crop production in aquaponics is influenced by water pH and potassium concentrations. The addition of hydroxide (KOH) into the recirculating aquaculture system (RAS) may benefit increasing for better biofilter activity supplementing K plant growth quality. We investigated growth, feed conversion, body composition welfare indicators juvenile African catfish (Clarias gariepinus) treated w...

In a previous work, the overall performance of modified Solvay process was investigated in absence ammonia, where carbon dioxide and brine treatments were accomplished single reaction presence calcium hydroxide (Ca(OH)2). this study, impact alkaline amphoteric oxides, namely potassium (KOH) aluminum oxide (Al2O3), on pH level, CO2 capture capacity, ions reduction, type produced solids at temper...

This study aims to provide an alternative soil improvement that can be applied in the Petobo area, which experienced liquefaction on September 29, 2018. Ferronickel slag is utilized as a binding agent. Furthermore, large concentrations of alkaline solutions (potassium hydroxide and sodium hydroxide) are activators activate kaolin initiate geopolymer production process. From test results, it con...

The stable of natural diatomite supported by potassium hydroxide (KOH) as catalysts were synthesized for biodiesel production. A heterogeneous base catalyst prepared impregnating KOH onto was also used to synthesize from palm oil. All samples have been thoroughly characterized Wavelength Dispersive X-ray Fluorescence (WDXRF), diffraction (XRD), N2 adsorption/desorption, Scanning electron micros...
