A process is disclosed for preparing and self-assembly of nanobinary and ternary metal oxyhydroxides with high surface area and 1-10 nm size by aerogel procedure, involving homogenization of metal organic precursors in solvent mixture, controlled hydrolysis, gelation, hydrothermal treatment and finally supercritical drying of solvent. The module includes a substrate, at least two power semiconductor components arranged on the substrate, a housing and outwardly routed load and control connections. The exposed outer surface of the laptop computer cover panel has a peripheral edge. Additionally, the pointing device provides for scrolling of the foreground windowed application when the cursor encounters an edge of display.
