'Greener,' low-cost transistor heralds advance in flexible electronics Posted: 24 Sep 2014 08:35 AM PDT As tech company LG demonstrated this summer with the unveiling of its 18-inch flexible screen, the next generation of roll-up displays is tantalizingly close. Researchers are now reporting a new, inexpensive and simple way to make transparent, flexible transistors -- the building blocks of electronics -- that could help bring roll-up smartphones with see-through displays and other bendable gadgets to consumers in just a few years.

Taking advantage of graphene defects: Security screening Posted: 24 Sep 2014 05:51 AM PDT Scientists have discovered a potential application for graphene in security screening. A new theoretical model estimates electric current rectification in graphene. Electronic transport in graphene contributes to its characteristics. Now, a Russian scientist proposes a new theoretical approach to describe graphene with defects-in the form of artificial triangular holes-resulting in the rectification of the electric current within the material. Specifically, the study provides an analytical and numerical theory of the so-called ratchet effect.
