Black Holes Could Help Detect Hypothetical Particle
2012-06-19 05:48:11

Lee Rannals for redOrbit.com Scientists have determined that previously undetected particles could be seen as they accumulate around black holes. Vienna University of Technology scientists have discovered a method to prove the existence of hypothetical "axions," which are particles with a very low mass. “The existence of axions is not proven, but it is considered to be quite likely”, Daniel Grumiller, a researcher on the project, said in a press release. Grumiller,...

Ongoing saga of building a better fuel cell catalyst goes holistic The design of a nature-inspired material that can make energy-storing hydrogen gas has gone holistic. Usually, tweaking the design of this particular catalyst -- a work in progress for cheaper, better fuel cells -- results in either faster or more energy efficient production but not both. Now, researchers have found a condition that creates hydrogen faster without a loss in efficiency. And, holistically, it requires the...

Precise Measurement Of Radiation Damage Identified
2012-06-06 06:55:26

Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material. "A full understanding of the early stages of the radiation damage process provides knowledge and tools to manipulate them to our advantage," said Alfredo Correa, a Lawrence Fellow from Lawrence Livermore National Laboratory in the Quantum Simulations Group. Nuclear radiation leads to highly energetic ions that can...

Physicists from the University of Bonn split an atom using quantum mechanics precision Researchers from the University of Bonn have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allow dividing atoms - similarly to light rays - and reuniting them. The researchers want to build quantum mechanics bridges by letting the atom touch adjacent atoms while it...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
