Physics/Chemistry News
Today's physics/chemistry headlines from the sources selected by our team:

Cooling with molecules
An international team of scientists have become the first ever researchers to successfully reach temperatures below minus 272.15 degrees Celsius – only just above absolute zero – using magnetic molecules. The physicists and chemists are presenting their new investigation today in the scientific journal Nature Communications. It was developed by six scientists from Bielefeld University, the University of Manchester, and the Universidad de Zaragoza. General Physics News, Thu, 23 Oct 2014 02:57:21 GMT

Technique for heat-assisted magnetic recording media promises improved writeability for next-generation hard drives
Heat-assisted magnetic recording (HAMR) is a new process that realizes the three goals of magnetic recording—readability, writeability and stability. A*STAR researchers have now succeeded in improving its writeability by employing a thermal design that permits a higher density recording1. General Physics News, Thu, 23 Oct 2014 02:57:21 GMT

Linear accelerator could improve X-rays, particle colliders
One drizzly morning in September, a giant metal tube painted Cornell red was loaded on a truck at the Wilson Synchrotron Laboratory annex to make a slow, steady journey across campus. General Physics News, Thu, 23 Oct 2014 02:57:21 GMT

Seeking 'absolute zero', copper cube gets chillingly close (Update)
An Italian lab has cooled a copper vessel with a volume of a cubic meter to within a tiny fraction of "absolute zero", setting a world record, the National Nuclear Physics Institute said Tuesday. General Physics News, Thu, 23 Oct 2014 02:57:21 GMT

Special microscope captures defects in nanotubes
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. Carbon nanotubes have been touted as exceptional materials with unique properties that allow for extremely efficient charge and energy transport, with the potential to open the way for new, more efficient types of electronic and photovoltaic devices. However, these traps, or defects, in ultra-thin nanotubes can compromise their effectiveness.

Scientists disprove theory that reconstructed boron surface is metallic
Scientific inquiry is a hit and miss proposition, subject to constant checking and rechecking. Recently, a new class of materials was discovered called topological insulators—nonmetallic materials with a metallic surface capable of conducting electrons. The effect, based on relativity theory, exists only in special materials -— those with heavy elements —- and has the potential to revolutionize electronics.

Extremely high-resolution magnetic resonance imaging
For the first time, researchers have succeeded to detect a single hydrogen atom using magnetic resonance imaging, which signifies a huge increase in the technology's spatial resolution. In the future, single-atom MRI could be used to shed new light on protein structures.
