One-nm-thick graphene engine mimics two-stroke engine
Scientists overcome fundamental atom laser limit to build brightest atom laser to date
Carbyne morphs when stretched: Calculations show carbon-atom chain would go metal to semiconductor
(Phys.org) —Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator, according to Rice University scientists.
Understanding graphene's electrical properties on an atomic level
(Phys.org) —Graphene, a material that consists of a lattice of carbon atoms, one atom thick, is widely touted as being the most electrically conductive material ever studied. However, not all graphene is ...
Physicists propose molecular clock to expose new physics
Boron 'buckyball' discovered
The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch.
'Nano-pixels' promise thin, flexible, high resolution displays
A new discovery will make it possible to create pixels just a few hundred nanometres across that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such ...
Superconducting-silicon qubits: Using a bottom-up approach to make hybrid quantum devices
Theorists propose a way to make superconducting quantum devices such as Josephson junctions and qubits, atom-by-atom, inside a silicon crystal. Such systems could combine the most promising aspects of silicon ...
Water behavior breakthrough opens a crucial door in chemistry
(Phys.org) —A multi-institutional team has resolved a long-unanswered question about how two of the world's most common substances interact.
Engineers envision an electronic switch just three atoms thick
Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today's smart phones process more data, but they still weren't built for being shoved ...
Not much force: Researchers detect smallest force ever measured
What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. Using ...
Theorists propose globally networked entangled atomic clock
New process designed to make Na-ion batteries an effective alternative to Li-ion
(Phys.org) —As the demand for rechargeable lithium-ion (Li-ion) batteries has grown, the battery industry has found itself facing a problem of supply-and-demand. Lithium is not an abundant element, and ...
Silicon alternatives key to future computers, consumer electronics
(Phys.org) —Researchers are reporting key milestones in developing new semiconductors to potentially replace silicon in future computer chips and for applications in flexible electronics.
