Imagine an electronic display nearly as clear as a window, or a curtain that illuminates a room, or a smartphone screen that doubles in size, stretching like rubber. Now imagine all of these being made from the same material. Researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have developed a transparent, elastic […]

Researchers use machine learning to boil down the stories that wearable cameras are telling
AUSTIN, Texas — Computers will someday soon automatically provide short video digests of a day in your life, your family vacation or an eight-hour police patrol, say computer scientists at The University of Texas at Austin. The researchers are working to develop tools to help make sense of the vast quantities of video that are […]
Toward a truly white organic LED
Utah physicists develop polymer with tunable colors SALT LAKE CITY, Sept. 13, 2013 – By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to “tune” the plastic-like polymer to emit light of different colors – a step toward more efficient, less expensive and truly white organic LEDs for light bulbs […]
Butterfly wings inspire new technologies: From fabrics and cosmetics to sensors
A new study has revealed that the stunning iridescent wings of the tropical blue Morpho butterfly could expand the range of innovative technologies. Scientific lessons learnt from these butterflies have already inspired designs of new displays, fabrics and cosmetics. Now research by the University of Exeter, in collaboration with General Electric (GE) Global Research Centre, […]
New kind of ultraviolet LED could lead to portable, low-cost devices
Light shines bright at precise frequencies that suit commercial applications COLUMBUS, Ohio—Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the technology. The patent-pending LED creates a more precise wavelength of UV light […]
Breakthrough in sensing at the nanoscale
Researchers have made a breakthrough discovery in identifying the world’s most sensitive nanoparticle and measuring it from a distance using light. These super-bright, photostable and background-free nanocrystals enable a new approach to highly advanced sensing technologies using optical fibres. This discovery, by a team of researchers from Macquarie University, the University of Adelaide, and Peking […]
Dartmouth researchers develop molecular switch that changes liquid crystal colors
Nanotechnology tool may help in in detecting harmful gases, pathogens, explosives Dartmouth researchers have developed a molecular switch that changes a liquid crystal’s readout color based on a chemical input. This new development may open the way for using liquid crystals in detecting harmful gases, pathogens, explosives and other chemical substances. The findings appear in […]
‘Groovy’ hologram creates strange state of light at visible and invisible wavelengths
Nanostructured device controls the intensity, phase, and polarization of light for wide applications in optics Cambridge, Mass. – August 20, 2013 – Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale […]
