Researchers from the Nanooptics and the Nanodevices groups at CIC nanoGUNE (Basque Country) in collaboration with colleagues at ICFO - The Institute of Photonic Sciences (Catalunya) have imaged how light moves inside an exotic class of matter known as hyperbolic materials. They observed, for the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride – a natural hyperbolic material for infrared light. This work has been funded by the EC Graphene Flagship and was recently reported in Nature Photonics.
The Spectroline® PC-4420A UV EPROM/Wafer Erasing System is a high-intensity unit with a large load capacity. It produces a nominal initial short-wave UV (254 nm) intensity of 46,000 µW/cm2 to ensure quick and complete erasure of programmed memory from every EPROM chip or wafer. This high-efficiency unit can complete an erasing cycle in just 4 minutes.
In the question of curly versus straight, new evidence suggests curly wins – at least in the world of nanowires. Researchers from Bilkent University, Ankara, Turkey, have shown that twisting straight nanowires into springs can increase the amount of light the wires absorb by up to 23 percent. Absorbing more light is important because one application of nanowires is turning light into electricity, for example to power tiny devices.
The Dirac cone, named after British physicist Paul Dirac, started as a concept in particle and high-energy physics and has recently became important in research in condensed matter physics and material science. It has since been found to describe aspects of graphene, a two dimensional form of carbon, suggesting the possibility of applications across various fields.
A team of physicists has taken pictures of a theorized but previously undetected magnetic wave, the discovery of which offers the potential to be an energy-efficient means to transfer data in consumer electronics.
Nikkiso America has delivered a 265nm line source for industrial curing applications. With individual UVC LEDs operating at powers up to 30 mW, the source includes a 2D array that delivers cw power density greater than 125mW / cm2 and uniformity of ± 10%.
Physicists from the Department of Nanophotonics and Metamaterials of ITMO University have experimentally demonstrated the feasibility of designing an optical analog of a transistor based on a single silicon nanoparticle.
Many semiconductor devices in modern technology – from integrated circuits to solar cells and LEDs – are based on nanostructures. Producing arrays of regular nanostructures usually requires substantial effort. If they were self-organized, the production of such devices would be considerably faster and the costs would therefore sink.
A team of researchers led by Nick Vamivakas of the University of Rochester has successfully used laser to levitate individual nanodiamonds in vacuum.
Much like birds fly in flocks to conserve energy, dolphins swim in pods to mate and find food, and colonies of ants create complex nests to protect their queens, immune cells engage in coordinated behavior to wipe out viruses like the flu.
