High-resolution SEM micrograph of iron oxide (a-Fe2O3) “nanograss” layer produced by thermal oxidation of an iron (Fe) foil at 600°C (Prof. Avner Rothschild). SEM_Micrograph
Metal-Ceramic Interface Group: The alumina hill was formed during the growth of alumina by vapor-liquid-solid deposition. Growth steps are visible at the hill surfaces (Prof. Wayne Kaplan) alumina-hill
CAE Group: MgF2 ALD coating on the surface of high voltage cathode powders (Prof. Yair Ein-Eli).

Nickel oxyhydroxide (NiOOH) is one of the best catalysts used for solar water splitting. That material is constituted by the stacking of H bonded layers. Water molecules and electrolyte species may diffuse between them (Prof. Maytal Caspary Toroker’s group) Nickel_oxyhydroxide
Zinc-oxide compounds for thermoelectric waste heat harvesting at high temperatures. A scanning electron microscope (SEM) micrograph taken from the surface of 3 at. % Ni-doped ZnO aged at 900 °C for 24 h showing NiO-precipitates dispersed in a ZnO-matrix. I. Koresh and Y. Amouyal.
