Gearing up nanoscale machines

Gear trains have been used for centuries to translate changes in gear rotational speed into changes in rotational force. Cars, drills, and basically anything that has spinning parts use them. Molecular-scale gears are a much ...

How carbon nanotubes could be used in future electronic devices

A team of Skoltech scientists, in collaboration with researchers from the IBM Watson Research Center, have shed light on the behavior of electrical contacts in carbon semiconductor nanotubes, which could pave the way to next-generation ...

Screens set to go green

Fitting the screens of electronic devices, such as televisions and smartphones, with a new display technology called 'organic light-emitting diodes' (OLEDs) will reduce their energy consumption, but such screens currently ...
