Developing an Eco-Friendly Deep-UV Lamp
ITHACA, N.Y., April 6, 2017 — Using atomically controlled thin monolayers of gallium nitride (GaN) and aluminum nitride (AlN) as active regions, a research group has shown the ability to produce deep-UV emission with an LED between 232 and 270 nm wavelengths. Currently, most deep-UV lamps are mercury-based and are bulky and inefficient. Researchers at Cornell University achieved electrically injected deep UV emission is obtained using monolayer thin GaN/AlN quantum structures as active regions and tuned the emission

SYDNEY, March 28, 2017 — A new nanoscale sensor has been developed that can help detect cytokines — molecules that play a critical role in cellular response to infection, inflammation, trauma and disease. Researchers at the Australian Research Council Centre of Excellence...
Optical Metamaterials Use III-V Semiconductors as Building Blocks
ALBUQUERQUE, N.M., March 28, 2017 — Materials that are more efficient than metals and that feature wider bandgap measures than silicon are being developed for possible use in optical metamaterial applications. All-dielectric materials using III-V semiconductors could be used to...
Nanoparticle Crystal Used to Control Light
EVANSTON, Ill. and ANN ARBOR, Mich., March 27, 2017 — A complex clathrate colloidal crystal has been created by connecting nanoparticles using DNA. One potential application for the novel crystal structures is the control of light.
fNIRS Tool Measures Brain’s Response to Acute Pain
BELLINGHAM, Washington and CARDIFF, U.K., March 27, 2017 — Functional near-infrared spectroscopy (fNIRS) — an optical imaging tool for monitoring regional blood flow and tissue oxygenation — is being explored as an option to track the brain's response to acute pain in adults and infants. Researchers from...
Terahertz Analysis Helps Target Measures for Controlling Pollution
BEIJING, March 24, 2017 — A combination of terahertz (THz) absorption and 2D correlation spectroscopy (2DCOS) has been used to identify the concentration and pollution sources of PM2.5 (particulate matter less than 2.5 µ in diameter) in the Beijing-Tianjing-Hebei...
