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...]
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...]
The US, Japan, and China Lead Grid Storage Market in 2017
Despite regulatory uncertainty, a highly-fragmented global market, and a risk-averse client base, the demand for energy storage on the grid will zoom to $113.5 billion in 2017, from a $2.8 billion market in 2012, reaching 185.4 gigawatt-hours (GWh) of capacity from 3.2 GWh, according to a Lux Research report. Lux Research analysts developed a dynamic Grid Storage Demand … [Read more...]
