Spray pyrolysis for ceramic powder preparation was studied, theoretically and experimentally. The forming mechanism for derived particles using air or argon as carrier was established based on the experimental results ...

A process for the electrochemical production of hydrogen gas and sulfur from hydrogen sulfide gas is disclosed. The process includes forming a substantially equimolar mixture of hydrosulfide and sodium hydrogen. That mixture ...

Surface modification of engineering materials has become more popular due to the scarcity of alloying elements like nickel and chromium and the increasing need for stronger and more corrosion resistant materials. On the ...

The coinage metals are oxidised to their respective cations (Cu+, Ag+, and Au+) at potentials that range from -0.20 V vs SCE for Cu to +1.30 V for Au. At glassy carbon hydroxide ion (-OH) is oxidized to O (+0.35 V vs SCE) ...

Fundamental and applied aspects of ion transport in polypyrrole films are investigated. In this context, three objectives have been accomplished: i) Composites of polypyrrole and a porous host membrane have been prepared ...

A mathematical model of a hydrogen/oxygen alkaline fuel cell is presented that can be used to predict the polarization behavior under various power loads. The major limitations to achieving high power densities are indicated ...

Ion-exchange membranes have found many uses for their special separation capabilities and are used currently in electrolysis and fuel cells, batteries, and chemical separations. Bilayer membranes have been particularly ...

An analysis of the production of sodium hydroxide (caustic) in diaphragm-type electrolyzers is presented. The analysis uses experimental data to characterize diaphragms in terms of measurable properties. These diaphragm ...

The maximum temperature difference allowed inside a nickel-hydrogen battery to avoid water relocation was calculated by a graphical method using the vapor pressure versus temperature correlation equation for water and ...
