Empa researchers discover why implant coatings detach: Nanocorrosion causes implants to fail|
Extra-hard coatings made from diamond-like carbon (DLC) extend the operating lifetime of tools and components. In artificial joints, however, these coatings often fail because they detach.

Empa grows "sea-urchin" shaped structures: More efficient photocells thanks to nanostructured surfaces|
Empa researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide nanowires. The structured surface should help increasing the efficiency of photovoltaic devices.

Investigating nanopillars - Silicon brittle? Not this kind!|
Silicon, the most important semiconductor material of all, is usually considered to be as brittle and breakable as window glass. On the nanometer scale, however, the substance exhibits very different properties, as Empa researchers have shown by creating minute silicon pillars.
