Jan. 14, 2019 — The absorption of light in semiconductor crystals without inversion symmetry can generate electric currents. Researchers have now generated directed currents at terahertz (THz) frequencies, much ... read more

Jan. 14, 2019 — Researchers have developed a 'hybrid technology' which shows the advantages of both light and magnetic hard drives. Ultra-short (femtosecond) light pulses allows data to be directly written ... read more

3D Printing 100 Times Faster With Light

Jan. 11, 2019 — Rather than building up plastic filaments layer by layer, a new approach to 3D printing lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing ... read more

Jan. 10, 2019 — Scientists have combined two membrane-bound protein complexes to perform a complete conversion of water molecules to hydrogen and ... read more

Jan. 10, 2019 — Distinguishing between left-handed and right-handed ('chiral') molecules is crucial in chemistry and the life sciences, and is commonly done using a method called circular dichroism. ... read more

Jan. 9, 2019 — Scientists have developed a new type of sensor platform using a gold nanoparticle array, which is 100 times more sensitive than current similar ... read more

'Environmentally Friendly' Flame Retardant Could Degrade Into Less Safe Compounds

Jan. 9, 2019 — To reduce the risk of fire, many everyday products -- from building materials to furniture to clothing -- contain flame retardants. In recent years, some of these compounds were shown to have harmful ... read more

Jan. 9, 2019 — Single lens eyes, like those in humans and many other animals, can create sharp images, but the compound eyes of insects and crustaceans have an edge when it comes to peripheral vision, light ... read more

Jan. 8, 2019 — Researchers have developed a new integrated photonics platform that can store light and electrically control its frequency (or color) in an integrated ... read more

Jan. 8, 2019 — A team of physicists has demonstrated the potential, for oncology, of an imaging technique based only on the physical properties of tumors. It can differentiate populations of malignant cells and ... read more

Nanophysicists Developed a High-Performance Organic Phototransistor

Jan. 8, 2019 — Converting light into electrical signals is essential for a number of future applications including imaging, optical communication and biomedical sensing. Researchers have now developed a new ... read more

Jan. 8, 2019 — Researchers have invented a new type of anti-counterfeiting device that can be useful for counterfeit deterrence of important documents such as identity cards, passports and ... read more

New Nanosatellite System Captures Better Imagery at Lower Cost

Jan. 4, 2019 — Researchers have developed a new satellite imaging system that could revolutionize the economics and imagery available from space-based cameras and even earth-based ... read more

Excitons Pave the Way to More Efficient Electronics

Jan. 4, 2019 — After developing a method to control exciton flows at room temperature, scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic ... read more

Jan. 4, 2019 — Researchers have discovered that electron spin is key to understanding how cuprate superconductors can conduct electricity without loss at high ... read more

Jan. 3, 2019 — Scientists made hollow nanosized boxes with corner holes, demonstrating how these ''nanowrappers'' can carry and release DNA-coated ... read more

Jan. 2, 2019 — A team of experimentalists discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with ... read more

Jan. 2, 2019 — In optogenetics, scientists use light to turn groups of neurons in the brain on or off. New research demonstrates a new optogenetics method that eliminates the need for bulky optical fibers, gives ... read more

Dec. 26, 2018 — Engineers have succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply. ... read more

Dec. 21, 2018 — Researchers have developed metasurfaces with extreme angle-asymmetric response. The new device can be a good or bad reflector depending on the angle the light hits ... read more
