a novel discrete singular convolution (dsc)  formulation  is  presented for the seepage analysis in irregular geometric porous media. the dsc is a new promising numerical approach which has been recently applied to solve several engineering problems. for a medium with regular geometry, realizing of the dsc for the seepage analysis is straight forward. but dsc implementation for a medium with ir...

This paper includes an overview of general approaches and efforts to enhance the power conversion efficiency in dye-sensitized solar cells (DSC) and then the recent development of hierarchically structured photoelectrodes for DSC. Hierarchically structured photoelectrodes are made of submicron-sized aggregates of ZnO nanocrystallites. Such structured photoelectrodes retain the desired large sur...
