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...

All-solid-state batteries using oxide electrolytes are regarded as safe batteries. However, most crystalline solid require high-temperature sintering for densification. Oxide with high formability, which enable the construction of high-performance batteries, thus required. In this study, Li4SiO4–Li2SO4 glasses and glass-ceramics were prepared by mechanochemical treatment subsequent heat at 270 ...

objective(s):the mesenchymal stem cells (mscs) have been introduced as appropriate cells for tissue engineering and medical applications. some studies have shown that topography of materials especially physical surface characteristics and particles size could enhance adhesion and proliferation of osteoblasts. in the present research, we studied the distinction effect of 30 and 60 μg/ml of zinc ...
