Graphene circuit ready for wireless
(Phys.org) —IBM researchers have built the world's most advanced fully functional integrated circuit made of wafer-scale graphene – a novel semiconductor material that has the potential to improve today's ...
Ceramics don't have to be brittle: Materials scientists are creating materials by design
Imagine a balloon that could float without using any lighter-than-air gas. Instead, it could simply have all of its air sucked out while maintaining its filled shape. Such a vacuum balloon, which could help ...
Chemists measure chilli sauce hotness with nanotubes
Oxford chemists have found a way of using carbon nanotubes to judge the heat of chilli sauces. The technology might soon be available commercially as a cheap, disposable sensor for use in the food industry.
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon chip.
