The cost of platinum and rhodium in the three-way catalyst accounts for a major fraction of the cost associated with treatment of automotive exhaust. therefore, striving to achieve a higher level of pollutant removal by increasing the platinum and rhodium contents in the three-way catalyst is not… More

A catalyst system using a special support material is proposed for simultaneous treatment of gaseous pollutants so2, co, nox, and hydrocarbons as well as particulate matterin flue gases from power plants. preliminary experiments ofa catalyst system using a special support material is proposed for… More

The large scale use of photovoltaic-generated electricity hinges crucially on the cost of its production. the high cost of production of the single crystal silicon technology has prohibited its terrestial exploitation. in spite of improvements here and the development of polycrystalline silicon, the… More
