Scientists at the Vienna University of Technology found a method to locate single gold atoms on a surface. This should pave the way to better and cheaper catalysts. Most people value large chunks of gold — but scientists at the Vienna University of Technology are interested in gold at the smallest possible scale, because single gold atoms are potentially the most reactive catalysts for chemical reactions. However, when gold atoms are placed on a surface they tend to ball up into tiny...

The storage of light-encoded messages on film and compact disks and as holograms is ubiquitous---grocery scanners, Netflix disks, credit-card images are just a few examples. And now light signals can be stored as patterns in a room-temperature vapor of atoms. Scientists at the Joint Quantum Institute have stored not one but two letters of the alphabet in a tiny cell filled with rubidium (Rb) atoms which are tailored to absorb and later re-emit messages on demand. This is the first time two...

Excitons form Bose-Einstein condensate Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will allow scientists to better study the physical properties of excitons, which exist only fleetingly yet offer promising applications as diverse as efficient harvesting of solar energy and ultrafast computing. "The realization of the exciton condensate in a trap opens the opportunity to study...

To modify a metal surface at the scale of atoms and molecules – for instance to refine the wiring in computer chips or the reflective silver in optical components – manufacturers shower it with ions. While the process may seem high-tech and precise, the technique has been limited by the lack of understanding of the underlying physics. In a new study, Brown University engineers modeled noble gas ion bombardments with unprecedented richness, providing long-sought insights into how...

Ultracold quantum gases are an ideal experimental model system to simulate physical phenomena in condensed matter. In these gases, many-body states can be realized under highly controlled conditions and interactions between particles are highly tuneable. A research group led by Wittgenstein awardee Rudolf Grimm and START awardee Florian Schreck have now realized and comprehensively analyzed repulsive polarons for the first time. The scientists from the Institute of Quantum Optics and Quantum...

Rice University physicists find reversible way to alter VO2“²s unique electronic about-face If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you´ve never heard of. It´s a metal. It´s an insulator. It´s a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2“²s electronic properties by treating it with one of the...

Kansas State University physicists and an international team of collaborators have made a breakthrough that improves understanding of matter-light interactions. Their research allows double ionization events to be observed at the time scale of attoseconds, which are one-billionth of a billionth of a second. The physicists have also shown that these ionization events occur earlier than thought -- a key factor to improving knowledge of correlated electron dynamics, which involve two...

A strong laser beam can remove an electron from an atom — a process which takes place almost instantly. At the Vienna University of Technology, this phenomenon could now be studied with a time resolution of less than ten attoseconds (ten billionths of a billionth of a second). Scientists succeeded in watching an atom being ionized and a free electron being "born". These measurements yield valuable information about the electrons in the atom, which up until now hasn't been experimentally...

There´s nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the “billiard balls” are tiny electrons moving across a “table” made of the semiconductor gallium arsenide. These tiny billiard tables are of interest towards the development of future computing technologies. In a research paper titled “The Impact of Small-Angle Scattering on...

barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
