Reversible solid oxide cells (r-SOCs) can be operated in either fuel cell or electrolysis mode. They are expected to become important the support of renewable energy due their high efficiency for both power generation and hydrogen generation. The exchange current density is one most parameters quantification electrode performance cells. In this study, four different electrodes two air fabricate...

This paper investigates the state-sponsored low cost housing provided to previously disadvantaged communities in the City of Cape Town. The strain imposed on municipal services by informal densification of unofficial backyard shacks was found to create unintended public health risks. Four subsidized low-cost housing communities were selected within the City of Cape Town in this cross-sectional ...

We present a fresh perspective on the Landau level quantization rule; that is, by successively including zero-field magnetic response functions at zero temperature, such as zero-field magnetization and susceptibility, the Onsager's rule can be corrected order by order. Such a perspective is further reinterpreted as a quantization of the semiclassical electron density in solids. Our theory not o...
