The heat analysis of binary current leads which consist of copper current lead and high temperature super conducting was made on condition that the lead was cooled by two-stage refrigerator.

To examine the global impact of acidification, the researchers developed a series of world maps to show current coal use, nutrient consumption, and copper production and smelting by country.

By running an electrical current through the cell, using an ordinary battery charger, the copper in the anode (and in the pins) dissolves and is deposited on the lead cathode.
