An economic evaluation of a hybrid wind/photovoltaic/fuel cell (FC) generation system for a typical home in the Pacific Northwest is performed. In this configuration the combination of a FC stack, an electrolyser, and hydrogen storage tanks is used as the energy storage system. This system is...

The size effect of the dielectric properties and the barrier height was investigated in the ferroelectric solid solution Ba<Subscript> x </Subscript>Sr<Subscript>1−x </Subscript>TiO<Subscript>3</Subscript> system. The decrease of the grain size causes the suppression of the ferroelectricity, and the increase of the relaxation frequency. Barrier heights increase...</subscript></subscript></subscript>

In this work, we study an inhomogeneous material, porous silicon (PS), using a supercell model and an s p3 s∗ tight-binding Hamiltonian. The interband non-vertical transitions are studied in two schemes, which consider different contributions within the intra-atomic approximation. The...

During the process of urbanization and industrialization, groundwater has been extensively overexploited, with the direct result of continuously decreasing groundwater level, followed by the appearance of large scale of depression cones, which is furthermore followed by land subsidence, seawater...

Environmental concerns associated with power generation drive an increasing interest in developing load management strategies to reduce pollutant emissions. Currently, no mechanism exists to directly influence pollutant emissions based on demand-side decisions. This shortcoming is addressed...
