 | The ISIS Second Target Station Project at the STFC Rutherford Appleton Laboratory in Oxfordshire achieved a major milestone on Friday 14 December, at the first attempt and two days ahead of schedule. Protons were successfully extracted into the new proton transfer beamline from the existing ISIS accelerator and delivered to the new target station. ...> Full Article |
 | The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity - and not incidentally, ruin the chip. Thermal expansion can also separate semiconducting materials from the substrate, reduce performance through changes in the electronic structure of the material or warp the delicate structures that emit laser light. ...> Full Article |
 | In the world of commercial materials, lighter and cheaper is usually better, especially when those attributes are coupled with superior strength and special properties, such as a material's ability to remember its original shape after it's been deformed by a physical or magnetic force. ...> Full Article |
New experiments address a barrier to efforts at developing computer networks that can run on light instead of electrons

 | Using concentrated solar energy to reverse combustion, a research team from Sandia National Laboratories is building a prototype device intended to chemically "reenergize" carbon dioxide into carbon monoxide using concentrated solar power. The carbon monoxide could then be used to make hydrogen or serve as a building block to synthesize a liquid combustible fuel, such as methanol or even gasoline, diesel and jet fuel. ...> Full Article |
A new study reports that a laser can be used to switch a film of vanadium dioxide back and forth between reflective and transparent states without heating or cooling it.

 | Using laser light to stir an ultracold gas of atoms, researchers have demonstrated the first 'persistent' current in an ultracold atomic gas -a frictionless flow of particles. This relatively long-lived flow, a hallmark of a special property known as 'superfluidity,' might help bring to the surface some deep physics insights, and enable super-sensitive rotation sensors that could someday make navigation more precise. ...> Full Article |
 | The next generation of laptops, desk computers, cell phones and other semiconductor devices may get faster and more cost-effective with research from Clemson University. ...> Full Article |
