NNCO to host free webinar for small- and medium-sized nanotechnology businesses

The National Nanotechnology Coordination Office (NNCO) will hold the second in a series of free webinars focusing on the experiences, successes, and challenges for small- and medium-sized nanotechnology businesses and on issues of interest to the nanotechnology business community on Wednesday May 20, 2015 from 2-3pm EDT.

Electrons in graphene corralled using new quantum tool

Researchers have succeeded in creating a new 'whispering gallery' effect for electrons in a sheet of graphene - making it possible to precisely control a region that reflects electrons within the material. They say the accomplishment could provide a basic building block for new kinds of electronic lenses, as well as quantum-based devices that combine electronics and optics.

New graphene nanofiltration application may enable faster, more durable water filters

Engineers have devised a process to repair leaksin graphene, filling cracks and plugging holes using a combination of chemical deposition and polymerization techniques. The team then used a process it developed previously to create tiny, uniform pores in the material, small enough to allow only water to pass through.

Scientists control the flow of heat and light in photonic crystals

Scientists have found a way to control heat propagation in photonic nano-sized devices, which will be used for high speed communications and quantum information technologies.

Using light to probe acoustic tuning in gold nanodisks

In a study that could open doors for new applications of photonics from molecular sensing to wireless communications, scientists have discovered a new method to tune the light-induced vibrations of nanoparticles through slight alterations to the surface to which the particles are attached.

Putting a new spin on plasmonics

Researchers have discovered a novel way of combining plasmonic and magneto-optical effects. They experimentally demonstrated that patterning of magnetic materials into arrays of nanoscale dots can lead to a very strong and highly controllable modification of the polarization of light when the beam reflects from the array.

Cotton fibres instead of carbon nanotubes

Plant-based cellulose nanofibres do not pose a short-term health risk, especially short fibres, shows a new study.
