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...]
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...]
Researcher Finds Cheaper Way To Cool Electronic Devices
A North Carolina State University researcher has developed a technique that uses a “heat spreader” made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film, both of which have higher thermal conductivity, allowing the device to cool efficiently. Dr. Jag Kasichainula, an associate professor of materials science and … [Read more...]
