No need for extrasolar delivery by comet: Nitrogen fingerprint in biomolecules could be from early Sun
Chemical fingerprints of the element nitrogen vary by extremes in materials from the molecules of life to the solar wind to interstellar dust. Ideas for how this great variety came about have included alien ...
Smallest possible diamonds form ultra-thin nanothreads
For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest ...
A nanosized hydrogen generator
(Phys.org) —Researchers at the US Department of Energy's (DOE) Argonne National Laboratory have created a small scale "hydrogen generator" that uses light and a two-dimensional graphene platform to boost ...
Nuclear spins control current in plastic LED: Step toward quantum computing, spintronic memory, better displays
University of Utah physicists read the subatomic "spins" in the centers or nuclei of hydrogen isotopes, and used the data to control current that powered light in a cheap, plastic LED – at room temperature ...
'Solid' light could compute previously unsolvable problems
Researchers at Princeton University have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter.
Phosphorus a promising semiconductor
(Phys.org) —Defects damage the ideal properties of many two-dimensional materials, like carbon-based graphene. Phosphorus just shrugs.
Engineers advance understanding of graphene's friction properties
(Phys.org) —An interdisciplinary team of engineers from the University of Pennsylvania has made a discovery regarding the surface properties of graphene, the Nobel-prize winning material that consists of ...
Electron microscopes take first measurements of nanoscale chemistry in action
(Phys.org) —Scientists' underwater cameras got a boost this summer from the Electron Microscopy Center at the U.S. Department of Energy's Argonne National Laboratory. Along with colleagues at the University ...
Cool calculations for cold atoms: New theory of universal three-body encounters
(Phys.org) —Chemical reactions drive the mechanisms of life as well as a million other natural processes on earth. These reactions occur at a wide spectrum of temperatures, from those prevailing at the ...
Superabsorbing ring could make light work of snaps
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.
