Curtiss-Wright Controls Defense Solutions has licensed Northrop Grumman Corporation's recently patented air-flow-through (AFT) cooling technology for use in CWCDS's rugged, deployed embedded systems. Northrop Grumman's AFT technology improves the air cooling of advanced electronic modules through the use of a compact core style heat exchanger design that significantly … [Read more...]
X-Ray Diffraction Reveals 3D Mechanics of Germanium-Crystal Arrays
Scientists at the European Synchrotron Radiation Facility (ESRF) are using X-ray diffraction to thoroughly understand a new type of nanostructure -- square arrays of germanium (Ge) pillars that have very complex geometries and physical attributes. Germanium grown epitaxially on micrometre-sized silicon pillars forms perfect crystals free of defects. The resulting Ge/Si … [Read more...]
Researchers Use Cold Atoms to Simulate Graphene
Scientists at ETH Zurich used a set of laser beams to create a honeycomb-like structure similar to that found in graphene. By loading ultracold atoms into this optical lattice, they can simulate electronic properties of this promising material. Such experiments may be used to identify electronic properties of materials which have yet to be discovered. Tilman Esslinger, … [Read more...]
Luminescent 'LED-Type' Design Breaks Efficiency Record
Researchers from the University of California, Berkeley have successfully designed a more efficient solar cell that is capable both of emitting light and absorbing it. The development came after researchers examined the reasoning behind why such a large gap existed between the theoretical limit to the amount of electrical energy that can be harvested by a solar cell and the … [Read more...]
Nanoscale Phenomena with Potential for Computer Speed Advances
A team of University of Maryland scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool. Understanding this completely unexpected new phenomenon could lead to new ways of building computer processors that can run at higher speeds without overheating. The researchers have dubbed the … [Read more...]
