RESUMEN
Li2MnO3-based composite, xLi2MnO3-(1--x)LiMO2 (M = Ni, Co, Mn, etc.), was synthesized via co-precipitation with sintering treatment. The composite material has hexagonal structure including a little of monoclinic with a nano-crystallite size. As a result, the material showed a specific redox behavior in the voltage range of 2.0-4.6 V and approximately 267 mAh/g of discharge capacity was obtained at the room temperature.
RESUMEN
Nanocrystallite ceria-doped scandia-stabilized zirconia (1Ce10ScSZ) powders are prepared using a combination of co-precipitation and hydrothermal treatments. Power density of 1.0 W cm(-2) is obtained at 1.6 A cm(-2) and 800 °C due to the drastic reduction of ohmic and polarization resistance in the SOFC cell.
RESUMEN
A silicon nanowire structure was fabricated using the electrochemical electroless etching method, involving electroless plating and the electrochemical etching process. The reflection of the absorption layer with the nanowires' structure was about 5%, which is better than a bulk-type solar cell (10%).
