New AFM methodology allows direct visualization of the structure of helical polymers

This is the first example of a chiral, dynamic helical polymer that shows such sense-selective packing in the 2D crystal.

OLED displays and solid-state lightings in mass production, coming soon

Researchers develop highly efficient, solution-processed fluorescence organic light-emitting diodes using 'pure-organic' emitters.

Physicists get a perfect material for air filters

An almost weightless fabric made of nylon nanofibers with a diameter less than 15 nm beats any other similar materials in terms of filtering and optical properties.

Lifetime breakthrough promising for low-cost and efficient OLED displays and lights

With just a tiny tweak, researchers greatly increased the device lifetime of organic light-emitting diodes (OLEDs) that use a recently developed class of molecules to convert electricity into light with the potential for increased efficiency at a lower cost in future displays and lighting.

New direction urged to improve cancer nanotechnology

Researchers involved in a national effort to develop cancer treatments that harness nanotechnology are recommending pivotal changes in the field because experiments with laboratory animals and efforts based on current assumptions about drug delivery have largely failed to translate into successful clinical results.

A new way to stretch DNA

A technique called acoustic force spectroscopy uses standing sound waves in a fluid channel to tug on DNA and other biomolecules in a precise and easily controllable way, revealing information about the molecules' structure and mechanical properties.

From backyard pool chemical to nanomaterial

Could a cheap molecule used to disinfect swimming pools provide the key to creating a new form of DNA nanomaterials?

Novel nanostructured ceramics convert wasted heat into electricity

Researchers designed nanostructured ceramics, which are thermoelectric materials that convert the heat produced un industrial processes into electrical energy.
