Nerve agents are among the world's most feared chemical weapons, but scientists at the National Institute of Standards and Technology have demonstrated a way to engineer carbon nanotubes to dismantle the molecules of a major class of these chemicals. In principle, they say, the nanotubes could be woven into clothing that destroys the nerve agents on contact before they reach the skin.
A research team using tunable luminescent nanocrystals as tags to advance medical and security imaging have successfully applied them to high-speed scanning technology and detected multiple viruses within minutes.
Not only rubber is elastic: There is also another, completely different form of elasticity known as superelasticity. This phenomenon results from a change in crystal structure and was previously only found in alloys and certain inorganic materials. A Japanese scientist has now introduced the first superelastic organic compound.
A Spin Your Thesis! experiment has shown that carbon nano materials are built differently under conditions of hypergravity. These results are useful for understanding the synthesis of carbon nano structures and the behaviour of gliding arc discharges.
'What a curious feeling', says Alice in Lewis Carroll's tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behavior we are used to seeing around us is turned on its head.
An international research team has built molecular 'clamps' out of DNA that offer a powerful new tool for identifying individuals with an increased risk of cancer. The clamp is capable of detecting genetic mutations, associated with cancer and other genetic diseases, with better specificity and affinity than more traditional techniques.
A group of leading microfluidics organisations in the 'Microfluidics Consortium' produced a 'Design for Manufacturing' guideline. This document contains a set of design guidelines, based on the expertise of consortium members working across a wide range of microfluidic techniques.
IK4-CIDETEC has taken another step in positioning itself as a centre of reference in advanced materials with the recent opening of its new facilities for polymer synthesis and processing of polymeric composites.
Researchers have demonstrated an intriguing way to accelerate nanoscale graphene structures to supersonic speeds, and have showed how to engineer materials to maintain these speeds over relatively long distances.
