Electrical and computer engineering researchers have developed a new kind of optical lens that is much thinner and lighter than conventional camera lenses that also works with night imaging, a future boon for smartphones that could flatten those unsightly 'camera bumps' as well as for drones and night vision cameras for soldiers.
Read moreEngineers are advancing what researchers know about hypersonic flight. A new study describes a series of tests that elucidate the conditions a future aircraft may experience traveling faster than 10 times the speed of sound.
Read moreResearchers have developed a compact infrared spectrometer. It's small enough to fit on a computer chip but can still open up interesting possibilities — in space and in everyday life.
Read moreResearchers have built what they believe is 'the world's most efficient single-photon source.' And they are still improving it. With planned upgrades, the apparatus could generate upwards of 30 photons at unprecedented efficiencies. Sources of that caliber are precisely what's needed for optical quantum information applications.
Read moreA team led by scientists has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. Their designed optical element focuses light to discrete points in a 3D helical pattern.
Read moreAccurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.
Read moreA research team develops an eco-friendly device that uses solar energy to catalyze an electrochemical oxidation reaction with high efficiency.
Read morePhorbiplatin is a new anti-cancer prodrug that can be controllably activated by red light. With its unique 'on-site' activation characteristic, this new prodrug can effectively kill cancer cells and minimize damage to normal tissues.
Read moreResearchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tunable optical couplers needed for networking applications and quantum information processing.
Read moreEnticed by the brilliant green hues of copper acetate and copper resinate, some painters in the Renaissance period incorporated these pigments into their masterpieces. However, by the 18th century, most artists had abandoned the colors because of their tendency to darken with time. Now, researchers have uncovered the chemistry behind the copper pigments' color change.
