Normal metals have an equal number of electrons with spin “up” and spin “down”. However, when there are more spins pointing up than down, or vice versa, the metal becomes a fer...
The history of science is littered with famous scientists who pushed the ‘wrong idea’, Perl told PhysicsWeb. And research organisations do not have a good track record of controlling the d...
At the DOE, the budget for basic energy science is set to rise by 11%, with two-thirds of this going to meet construction costs for the Spallation Neutron Source being built at Oak Ridge. Fusion resea...
Jaakkola observed two-dimensional Bose-Einstein condensation (2D BEC) in a gas of specially prepared hydrogen atoms adsorbed on the surface of liquid helium. In Bose-Einstein condensation all the part...
Vertical cavity lasers work by having a quantum well sandwiched between alternating layers of gallium arsenide (GaAs) and aluminium gallium arsenide (AlGaAs). As the two materials have different refra...
The technique works because two different ions, gadolinium and europium, are in the phosphor material. The UV light boosts a gadolinium ion to its excited state. This excess energy is then transferred...
Researchers at the Dubna Laboratory of Heavy Ion Nuclear Reactions in Russia, headed by Yuri Oganessian, collaborating with a team from the Lawrence Livermore National Laboratory in the US, made the d...
“This is certainly the quickest movement since we started measurements in Greenland in 1928, ” says Torsten Neubert, who heads DMI’s Solar-Terrestrial Physics Department. Neubert thi...
Scientific publishing is still a highly profitable business. According to Nature, the scientific side of the Reed-Elsevier publishing company made a profit of $378m on sales of $938m in 1997. However,...
