as a plating bath. The compsn. becomes an easily handleable liq. at ordinary temp. and has high ionic conductivity in a molten state. Since tetraalkylphosphonium cations are electrochemically stable, plating can be carried out at a higher temp. and high current density. 展开 ...
Different materials such as glass, stainless steel, tin, aluminum alloy (called “mixed” in the paper), aluminum and copper were used as the heat exchanger’s container materials in the numerical calculations. One side of the cubic container was maintained at a constant temperature, whereas the...
