This new material consists of many identical piece of grossly warped graphene, each containing exactly 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms decorating the rim. These individual molecules, because they measure somewhat more than a nanometer across, are ref...
Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled.
The most instantly recognizable image of an atom resembles a miniature solar system with the concentric electron paths forming the planetary orbits and the nucleus at the centre like the sun.
Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology.
An electrical field applied to an ultra-thin layer of material can turn the polarisation of the beam as required. This produces an efficient transistor for light that could be miniaturised and used to build optical computers.
There are several different ways to trap light and now, researchers have designed another method to manage the feat. Scientists at MIT have developed a new system that pits light waves against light waves; the technique could have a wide variety of practical applications.
When water becomes cold, it usually turns into ice. Now scientists have discovered that water transforms into a new kind of liquid when its supercooled to extreme temperatures.
Creating normal space-time from an earlier state dominated by quantum gravity has been studied for years; now, recent analyses reveal that not all elementary particles may be subject to the same space-time.
Oak Ridge National Laboratory (ORNL) in Tennessee, US, is home to the Spallation Neutron Source (SNS), which produces the most intense neutron beams in the world. Scientists study how the neutrons scatter when different materials are exposed to the beams.
The radioactive element astatine, the name of which is derived from the Greek word for 'instability,' is so rare on earth that it has not yet been investigated to any greater extent and, as a consequence, very little is known about it.
Superconductivity occurs when matter is able to conduct electricity without any resistance. Now, scientists have found some surprising superconductivity in a solvent.
There's been a lot of talk about the D-Wave processor housed at the USC-Lockheed Marin Quantum Computing Center. Now, scientists have discovered that the D-Wave processor behaves in a manner that indicates that quantum mechanics has a functional role in the way it works.
