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...]
Air-to-Air Thermoelectric Cooling Assembly
Marlow Industries announced the availability of a new high-performance air-to-air thermoelectric cooling assembly—Climatherm. The new assemblies provide up to 125 percent greater performance than current air-to-air thermoelectric assemblies, in an exceptionally light and compact package. Marlow’s new cooling assembly provides protection in extreme temperatures and carries IP55 … [Read more...]
Magnetic Testing Ensures Reliability of Microelectronic Devices
Researchers at the Georgia Institute of Technology have developed a new technique for measuring the adhesion strength between thin films of materials used in microelectronic devices, photovoltaic cells and MEMS using magnetic repulsion. The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long-term reliability of … [Read more...]
