Laser pulse turns glass into a metal

For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by calculations at the Vienna University of Technology. The effect ...

With 'ribbons' of graphene, width matters

Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to "tune" the wonder material, ...

Caps not the culprit in nanotube chirality

(Phys.org) —A single-walled carbon nanotube grows from the round cap down, so it's logical to think the cap's formation determines what follows. But according to researchers at Rice University, that's not ...
