Insulators made into conductors: Polymers coaxed to line up, transformed into materials that could dissipate heat
Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But scientists have now found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.

New way forward for nanocomposite nanostructures
Scientists recently reported a new technique for directly writing composites of nanoparticles and polymers. Recent years have seen significant advances in the properties achieved by both these materials, and so researchers have begun to blend these materials into nanocomposites that access the properties of both materials.

New device for ultrafast optical communications
A new device invented by engineers in California could make it much faster to convert pulses of light into electronic signals and back again. The technology could be applied to ultrafast, high-capacity communications, imaging of the Earth's surface and for encrypting secure messages.

Campaign to end sale of electronic mosquito repellents
A campaign to stop the sale of electronic mosquito repellents by major airlines is beginning to bear fruit with the immediate withdrawal of the products from KLM flights. The issue, say experts, is that these electronic repellents, sold to airline passengers, many on their way to malaria endemic countries, just don’t work.

Lab on a chip: Ordinary cotton thread used to stitch together low-cost microfluidic analytical device
In a world first, the researchers have used ordinary cotton thread and sewing needles to literally stitch together the uniquely low-cost microfluidic analytical device, which is the size of a postage stamp and allows scientists to carry out chemical analyses of minute fluid samples, such as blood and urine.

New graphene 'nanomesh' could change the future of electronics
Scientists have created a new graphene nanostructure called the graphene nanomesh (GNM). The new structure is able to open up a band gap in a large sheet of graphene to create a highly uniform continuous semiconducting thin film. The concept of the GNM therefore points to a clear pathway towards practical application of graphene as a semiconductor material for future electronics.
