Technique to Control Light from Nanoparticles
September 29, 2011 — Chemists have discovered a way to use liquid crystals to control light scattered from gold nanorods. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules ... > full story -
Single Ions -- Extremely Cool: Single Magnesium Ion Brought to a Standstill by Means of Novel, Simple Laser Cooling
September 29, 2011 — One of the fundamental questions in the search for the "theory of everything" is whether fundamental constants possibly vary. To prove this in the case of the fine-structure constant, for instance, ... > full story -
Redefining the Kilogram and the Ampere
September 29, 2011 — New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two Système Internationale ... > full story -
Matter Shows Abrupt Escape from Flatness: Lead Made to Undergo a Rapid Transition from 'Pancake' to Hemisphere
September 28, 2011 — At first glance, it seems as if billions of lead atoms have mysteriously disappeared. When exposed to heat, a layer of lead coated onto a nickel surface becomes almost invisible from one moment to ... > full story -
CERN Sets Course for Extra-Low-Energy Antiprotons
September 28, 2011 — The kick-off meeting for ELENA, the Extra Low Energy Antiproton Ring, has begun at CERN . Approved by CERN Council in June this year, ELENA is scheduled to deliver its first antiprotons in ... > full story -
Light from Galaxy Clusters Confirms General Theory of Relativity
September 28, 2011 — All observations in astronomy are based on light (electromagnetic radiation) emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. ... > full story -
Quantum Teleportation Analysed by Mathematical Separation Tool
September 27, 2011 — Scientists recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical ... > full story -
How Graphene's Electrical Properties Can Be Tuned
September 26, 2011 — Graphene is ideally suited for creating components for semiconductor circuits and computers. Now, an accidental discovery in a physicist's laboratory, provides a unique route for tuning the ... > full story -
Cheap and Efficient Solar Cell Made Possible by Linked Nanoparticles
September 26, 2011 — Researchers have demonstrated that electrons can move freely in layers of linked semiconductor nanoparticles under the influence of light. This new knowledge will be very useful for the development ... > full story -
Hints of Universal Behavior Seen in Exotic Three-Atom States
September 23, 2011 — A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. A new experiment ... > full story
