Collaboration uses Lehigh's advanced electron microscopes to pinpoint phase transition Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities? The phenomenon, known as liquid metal embrittlement, or LME, has baffled metallurgists for a century. Now, a team of ceramics researchers has shed light on LME by obtaining atomic-scale images of unprecedented resolution of the...

  A KAIST research team has developed a new type of biocompatible and bendable GaN LED biosensor [ View the Video ] Can a flexible LED conformably placed on the human heart, situated on the corrugated surface of the human brain, or rolled upon the blood vessels, diagnose or even treat various diseases? These things might be a reality in the near future. The team of Professor Keon Jae Lee (Department of Materials Science and Engineering, KAIST) has developed a new concept: a...

Using advanced theoretical computations, a team of Kentucky scientists has derived a means to "tweak" an inexpensive semiconductor to function as photoelectrochemical catalyst. Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight. The research, funded by the U.S. Department of Energy, was led by Professors Madhu Menon and R. Michael Sheetz at...

Paul Preuss, Berkeley Lab Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a band gap that can respond to sunlight's full range, from low-energy infrared through visible light to high-energy ultraviolet. Although full-spectrum solar cells have been made, none yet have been suitable for manufacture at a consumer-friendly price. Now Wladek...

Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip. The technique, which they describe in the journal Science, involves rearranging the holes left by missing atoms to tune the properties of dopants "“ the chemical impurities that give the semiconductors in computer chips their special properties. Though the technique is currently limited to the laboratory, it could prove valuable to...

Researchers use magnets to tune supercooled gallium arsenide semiconductors Physicists from Rice University and Princeton University have discovered how to use one of the information technology industry's mainstay materials -- gallium arsenide semiconductors -- as an ultrasensitive microwave detector that could be suitable for next-generation computers. The discovery comes at a time when computer chip engineers are racing both to add nanophotonic devices directly to microchips and to boost...

New ultra-clean nanowires produced at the Nano-Science Center, University of Copenhagen will have a central role in the development of new high-efficiency solar cells and electronics on a nanometer scale. PhD student Peter Krogstrup, Niels Bohr Institute, in collaboration with a number of well-known researchers and the company SunFlake A/S, is behind the breakthrough. The new findings have recently been published in the prestigious journal Nano Letters. Nanowires are one-dimensional...
