Building 3-D fractals on a nano scale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating ...

Portable device helps doctors diagnose sepsis faster

EPFL researchers have developed a highly sensitive and portable optical biosensor that stands to accelerate the diagnosis of fatal conditions like sepsis. It could be used by ambulances and hospitals to improve the triage ...

Researchers discover switching function in molecular wire

The increasing miniaturisation in electronics will result in components which consist of only a few molecules, or even just one molecule. Tiny wires are required to connect these to an electrical circuit at the nano level. ...

Anti-reflective coating inspired by fly eyes

The eyes of many insects, including the fruit fly, are covered by a thin, transparent coating made up of tiny protuberances with anti-reflective, anti-adhesive properties. An article published in the journal Nature reveals ...

Less friction loss in combustion engines

Researchers have developed a method that can reduce engine friction and wear even during production of engine components. Special coatings can help to reduce fuel consumption and CO2 emissions.
