Graphene exhibits bizarre new behavior well suited to electronic devices
Graphene, a sheet of pure carbon, has been touted as a possible replacement for silicon-based semiconductors because of its useful electronic properties. Now, physicists have shown that graphene has another unique and amazing property that could make it even more suitable for future electronic devices. When contorted in a specific way it sprouts nanobubbles in which electrons behave as if they are moving in a strong magnetic field.

Behind the secrets of silk lie high-tech opportunities
Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silks spun by worms and spiders are a masterpiece of nature whose properties have yet to be fully replicated in the laboratory. But scientists have begun to unravel the secrets of silk. Biomedical engineers report that silk-based materials have been transformed from commodity textile to a growing web of high tech applications.

First step toward electronic DNA sequencing: Translocation through graphene nanopores
Researchers have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules. Using electric fields, the tiny DNA strands are pushed through nanoscale-sized thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.

An alchemist’s dream: Lead-free electronics
It’s been said that the typical mobile phone contains roughly half of all elements found on the Periodic Table. One of the most problematic substances used in phones and other electronics is lead. But making lead-free electronics has proved problematic – until now. Researchers have now developed a method that enables the industrial production of a substance that can be used to replace lead in many electronic applications.
