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.
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.
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.
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.
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.
Some substances, when they undergo a process called rapid-freezing or supercooling, remain in liquid form - even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
Researchers developed an inkjet printing technology to produce kesterite thin film absorbers (CZTSSe). Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 % have been achieved.
