RISTreatment of Acid Rock Drainage in a Meromictic Mine Pit Lake
Publisher: American Society of Civil Engineers
Abstract: The Island Copper Mine pit near Port Hardy, Vancouver Island, B.C., Canada, was flooded in 1996 with seawater and capped with fresh water to form a meromictic (permanently stratified) pit lake of maximum depth 350 m and ...
Improved Efficiency of Dye-Sensitized Solar Cells Using a Vertically Aligned Carbon Nanotube Counter Electrode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dye-sensitized solar cells (DSSCs) offer many advantages in comparison to their Si-based counterparts, including lower cost of raw materials, faster manufacturing time, and the ability to be ...
Effect of Phonon Dispersion on Thermal Conduction Across Si/Ge Interfaces
