Cooling with the coldest matter in the world

Cooling with the coldest matter in the world
Basel, Switzerland (SPX) Nov 25, 2014 - Physicists at the University of Basel have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute zero. This technique may enable novel studies of quantum physics and precision measurement devices, as the researchers report in the journal Nature Nanotechnology. Ultra ... more

Chinese island project in disputed waters 'justifiable': general
Beijing (AFP) Nov 24, 2014 - Beijing on Monday fired back at US criticism of an artificial island project in the disputed South China Sea that could reportedly include an airstrip, with a top general defending it as "justifiable". People's Liberation Army Major General Luo Yuan told the state-run Global Times newspaper that Beijing was building infrastructure on the reef and the US should stay out of the issue. "The ... more

An efficient method to measure residual stress in 3D printed parts

An efficient method to measure residual stress in 3D printed parts
Livermore CA (SPX) Nov 17, 2014 - Lawrence Livermore National Laboratory researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing. This 3D printing process produces metal parts layer by layer using a high-energy laser beam to fuse metal powder particles. When each layer is complete, the build platform moves downward by the thickness of one ... more

Field-emission plug-and-play solution for microwave electron guns

Field-emission plug-and-play solution for microwave electron guns
Washington DC (SPX) Nov 19, 2014 - On a quest to design an alternative to the two complex approaches currently used to produce electrons within microwave electron guns, a team of researchers from Euclid TechLabs and Argonne National Laboratory's Center for Nanoscale Materials have demonstrated a plug-and-play solution capable of operating in this high-electric-field environment with a high-quality electron beam. Unfamiliar ... more

Schker-blop! The sound of a comet touchdown

Schker-blop! The sound of a comet touchdown
Paris (AFP) Nov 20, 2014 - No trumpet sounded to mark the historic event - instead, it was a hollow, springy plop which heralded last week's landing by the comet probe Philae. Scientists at the German space agency DLR on Thursday said they had recorded vibrations from sensors on Philae's three legs as the robot lab touched down on Comet 67P/Churyumov-Gerasimenko. There is no sound in space, so the team transcribe ... more
