Revving up fluorescence for superfast LEDs
Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal—setting a speed record and making an important step toward realizing superfast LEDs and quantum cryptography.
Strengthening thin-film bonds with ultrafast data collection
A new research tool invented by researchers at Lawrence Livermore National Laboratory, Johns Hopkins University, and the National Institute of Standards and Technology captures information about both temperature and crystal structure during extremely fast reactions in thin-film materials.
NTU develops ultra-fast charging batteries that last 20 years
Scientists at Nanyang Technology University have developed ultra-fast charging batteries that can be recharged up to 70% in only two minutes. The new generation batteries also have a long lifespan of over 20 years, more than 10 times that of existing lithium-ion batteries.
Unique catalysts for hydrogen fuel cells synthesized in kitchen microwave oven
Swedish and Chinese researchers show how a unique nano-alloy composed of palladium nano-islands embedded in tungsten nanoparticles creates a new type of catalysts for highly efficient oxygen reduction, the most important reaction in hydrogen fuel cells.
Whether on baby bottles, beer mugs or perfume bottles, imprints on glass consist mainly of lead oxide. But Fraunhofer researchers have developed printing inks for glass that do not contain any toxic elements.
Dissolvable silicon circuits and sensors
Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign. The advances suggest a new era of devices that range from green consumer electronics to biomedical sensor systems that do their work and then disappear.
Beyond LEDs: Brighter, new energy-saving flat panel lights based on carbon nanotubes
Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes with very low power consumption of around 0.1 W for every hour’s operation—about a hundred times lower than that of an LED.
