Nano-sensor measures tension of tissue fibres

Bacteria are able to attach themselves to tissue fibres with the aid of a 'nano-adhesive'. Just how they achieve this was investigated a few years ago by Viola Vogel, Professor of Applied Mechanobiology at ETH Zurich, using ...

The microscopic origin of efficiency droop in LEDs

Light-emitting diodes—or LEDs, as they are commonly known—have been slowly replacing incandescent light bulbs in applications ranging from car taillights to indicators on electronics since their invention in the 1960s.

Nano-watch has steady hands

An international team from the Universities of Vienna, Duisburg-Essen and Tel Aviv have created a nanomechanical hand to show the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less ...

Three-dimensional nanomagnets for the computer of tomorrow

Since the late 1960's, electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have created a nanoscale magnetic circuit capable of moving ...

3-D-printed device builds better nanofibers

Meshes made from fibers with nanometer-scale diameters have a wide range of potential applications, including tissue engineering, water filtration, solar cells, and even body armor. But their commercialization has been hampered ...
