Spot-welding graphene nanoribbons atom by atom
Scientists at Aalto University and Utrecht University have created single atom contacts between gold and graphene nanoribbons.
Beyond stain-resistant: New fabric coating actively shrugs off gunk
Scientists are reporting development and successful testing of a fabric coating that would give new meaning to the phrase "stain-resistant" -- a coating that would take an active role in sloughing off grease, ...
Microtechnology: Miniature magnetic switches
Transistors are commonly used in electronics as switches to turn an electrical current on or off. For applications that require a very large ratio between the on and off current, however, it is necessary to ...
Nanotubes find niche in electric switches
New research from Rice University and the University of Oulu in Oulu, Finland, finds that carbon nanotubes could significantly improve the performance of electrical commutators that are common in electric ...
X-rays illuminate nitrogen's role in single-layer graphene
(Phys.org)—Researchers using x-rays to study a single-atom-thick layer of carbon, called graphene, have learned new information about its atomic bonding and electronic properties when the material is "doped" ...
