Carbon nanotubes best for 3D electronics

(PhysOrg.com) -- Researchers at Chalmers have demonstrated that two stacked chips can be vertically interconnected with carbon nanotube vias through the chips. This new method improves possibilities for 3D integration of ...

Scientists review worldwide rise of 'network of networks'

The interdisciplinary field of network science has attracted enormous attention in the past 10 years, although most results have been obtained by analyzing isolated networks. However many real-world networks interact with ...

New model suggests how the brain might stay in balance

(PhysOrg.com) -- Physicists have theorized for decades about how neural networks might be able to accomplish the incredibly complex calculations the human brain performs all the time. But simply stabilizing such a powerful ...

Researching graphene nanoelectronics for a post-silicon world

Copper's days are numbered, and a new study at Rensselaer Polytechnic Institute could hasten the downfall of the ubiquitous metal in smart phones, tablet computers, and nearly all electronics. This is good news for technophiles ...

Needle beam could eliminate signal loss in on-chip optics

(Phys.org)—An international, Harvard-led team of researchers have demonstrated a new type of light beam that propagates without spreading outwards, remaining very narrow and controlled along an unprecedented distance. This ...
