You can't teach old materials new tricks
A more sensitive, more selective and easily deployable radiation detection material is necessary to meet complex 21st century challenges. In the AAAS symposium (2008-02-16)

Graphene looking promising for future spintronic devices
Researchers at Chalmers University of Technology have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers. The findings will be published in the journal Nature Communications. (2015-04-10)

Researchers create unexpected glass within a glass
University of Cincinnati researchers report in the April 26th issue of Nature that they have created a glassy form of silver iodide. The compound has never been seen in a glassy form; however, the researchers succeeded by using another (2001-04-24)

Organic electronics: Semiconductors as decal stickers
No more error-prone evaporation deposition, drop casting or printing: Scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich and FSU Jena have developed organic semiconductor nanosheets, which can easily be removed from a growth substrate and placed on other substrates. (2017-05-08)

Quantization of 'surface Dirac states' could lead to exotic applications
Researchers from the RIKEN Center for Emergent Matter Science in Japan have uncovered the first evidence of an unusual quantum phenomenon -- the integer quantum Hall effect -- in a new type of film, called a 3-D topological insulator. This discovery could help move science forward toward the goal of dissipationless electronics -- electronic devices that can operate without producing the vast amounts of heat generated by current silicon-based semiconductors.
