Fast molecular rearrangements hold key to plastic's toughness

A new report says that subjecting a common plastic to physical stress - which causes the plastic to flow - also dramatically increases the motion of the material's constituent molecules, with molecular rearrangements occurring up to 1,000 times faster than without the stress.

3D nanowire FET extends transistor dimension scaling

French research institute CEA-LETI has successfully integrated on the same SOI wafer different types of advanced transistor structures like stacked nanowires transistors, FINFETs and independent dual gate FET, using a common flow compatible with standard planar FDSOI devices.

Using invisibility to increase visibility

Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat?s eye.

Harnessing light to drive nanomachines

Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering and Applied Science has shown that the force of light indeed can be harnessed to drive machines - when the process is scaled to nano-proportions.

Nanoscale imaging reveals mother of pearl secret

In addition to its iridescent beauty, mother of pearl, or nacre, the inner lining of the shells of abalone, mussels and certain other mollusks, is also renowned for an amazing strength and toughness that has been a long-standing mystery. Now, scientists have brought to light a new aspect of nacre?s nanostructural architecture using the polarized x-ray beams and nanoscale imaging capabilities of the Advanced Light Source (ALS), a national synchrotron facility at the Lawrence Berkeley National Laboratory.

Barcode chip promises to revolutionize diagnostic medical testing

A new 'barcode chip' developed by researchers at the California Institute of Technology (Caltech) promises to revolutionize diagnostic medical testing. In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.
