Polymer-Coated Silicon Nanosheets May Be Graphene Alternative
MUNICH, March 15, 2017 — Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene; however, alone nanosheets are less stable. Researchers at the Technical University of Munich (TUM) have produced a novel composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process, bringing about possible future industrial applications like flexible displays and photosensors. "Silicon nanosheets are particularly

Green LED Provides Safe, Inexpensive Treatment of Chronic Pain
TUCSON, Ariz., March 9, 2017 — Exposure to green LED could provide an inexpensive, non-pharmacological approach to managing chronic pain, by altering the levels of endogenous substances that potentially inhibit pain and decrease inflammation of the nervous system.
Chiral Metamaterial Causes Optical Shift in mW Range
ATLANTA, March 9, 2017 — A metamaterial with chiroptical properties in the nonlinear regime has shown the ability to produce a significant spectral shift with power levels in the milliwatt (mW) range. Two absorptive resonances were spectrally modified through incremental...
Nano 'Sandwich' Could Enhance Optical Properties, Tunability of Graphene
HOUSTON, March 7, 2017 — Use of a “nanoscale sandwich,” made from two atom-thick slices of graphene around nanoclusters of magnesium oxide (MgO), could expand the optoelectronic properties for graphene. Researchers at Rice University, using previous experiments...
Fluorogenic Polymer Can Detect Mercury Levels in Fish
BURGOS, Spain, March 7, 2017 — A novel fluorescent polymer that lights up when it makes contact with mercury that may be present in fish could be used to reduce the sale and consumption of fish containing mercury levels deemed to be unsafe by the European Food Safety Authority...
Small, Low-Cost Remote Sensing Satellites Could Orbit Much Closer to Earth
MANCHESTER, England, March 7, 2017 — Smaller and less expensive satellites may soon orbit much closer to Earth improving the quality of images they send back. The University of Manchester is heading up this project to develop remote sensing satellites that can operate at 200-450...
Marshall, O'Hagan Recognized by LIA
ORLANDO, Fla., March 7, 2017 — The Laser Institute of America (LIA) has awarded its 2017 George M. Wilkening Award to Wesley J. Marshall, principal of Laser Safety Specialties, for his contributions to laser safety. The George M. Wilkening Award is presented to individuals who...
PHABLABS Initiative Aims to Reach Youth, Young Professionals
BRUSSELS, March 7, 2017 — The PHABLAB 4.0 initiative, aiming to achieve lasting photonics integration in the expanding ecosystems of European Fab Labs and Makerslabs, has announced its startup phase. Together with 27 partners, tailored workshops and projects will be...
Low-Cost Monitoring Device Detects Oil's Fluorescence Fingerprint
VIGO, Spain, March 6, 2017 — A simple device composed of photodiode detectors can detect an oil spill in water and then pinpoint the type of oil present on the surface. Researchers from the University of Vigo created the device that is designed to float on water, where it could...
Material Reduces Signal Loss, Boost Efficiency of Light-Based Devices
LA JOLLA, Calif., March 3, 2017 — Photonic devices could see a reduction in optical signal loss, as a result of the discovery of a plasmonic metamaterial that compensates for loss of light energy by using a semiconductor to act as a light emitter. Plasmonic metamaterials typically...
