This paper presents the results of investigations into modeling DC and dynamic characteristics an alkaline electrolyzer. A model device under consideration is proposed in form analytical relationships which coefficients depend on concentration potassium hydroxide solution contained electrolyzer consideration. The correctness verified by comparing calculated measured current–voltage dependence m...

The key to realize long-life high energy density lithium batteries is exploit functional electrolytes capable of stabilizing both voltage cathode and anode. emergence localized high-concentration (LHCEs) shows great promise for ameliorating the above-mentioned interfacial issues. In this work, a difluoro(oxalate)borate (LiDFOB) based nonflammable dual-anion LHCE designed prepared. Dissolving in...

Abstract Cocoa peel activated carbon has been successfully synthesized with 0.3 M KOH activator and NaCl electrolyte as the base material for supercapacitor electrodes. Variations in concentration of used were 1 M, 2 3 to determine their effect on capacitance, conductivity, pore area values produced. The produced was characterized by Scanning Electronic Microscope (SEM) see surface morphology, ...

The present work reports the electrochemical machining (ECM) of the aluminium-silicon alloy/boron carbide (Al-Si /B4C) composites, fabricated by stir casting process with different weight % of B4C particles. The influence of four machining parameters including applied voltage, electrode feed rate, electrolyte concentration and percentage of reinforcement on the responses surface roughness (SR) ...

UNLABELLED A solid polymer electrolyte system based on poly(vinyl alcohol) (PVA) and poly(3,4-Etylenedioxythiophene):poly(styrenesulfonate) ( PEDOT PSS) complexed with magnesium bromide (MgBr2) salt was prepared using solution cast technique. The ionic conductivity is observed to increase with increasing MgBr2 concentration. The maximum conductivity was found to be 9.89 × 10(-6) S/cm for opti...

The high sweat electrolyte concentration in cystic fibrosis is most important in the diagnosis of this disease. The method used for its determination should be simple to perform, harmless to the patient, and accurate. The widely-used method of collecting sweat on a filter paper (Shwachman, Leubner, and Catzel, 1955) after pilocarpine iontophoresis (Gibson and Cooke, 1959) fulfils the first two ...

zn-co electrodeposits have attracted interest because of their significantly higher corrosion resistance in comparison with pure zinc. in this research the influence of bath temperature and electrolyte’s co 2+ concentration on the morphology and composition of the zn-co coatings, electrodeposited on an aisi1018 steel substrate from a weakly alkaline glycine solutions, has been studied. sem and ...
