Jul 26, 2024 (Nanowerk News) It is no mystery that light is essential to human life. Since the discovery of fire, humans have developed various artificial light sources, such as incandescent lamps, gaslights, discharge lamps, and light-emitting diodes (LEDs). The distribution and intensity of artificial lights indoors are important factors...
Shining light on similar crystals reveals photoreactions can differ
Jul 26, 2024 (Nanowerk News) A rose by any other name is a rose, but what of a crystal? Osaka Metropolitan University-led researchers have found that single crystals of four anthracene derivatives with different substituents react differently when irradiated with light, perhaps holding clues to how we can use such...
‘Kink state’ control may provide pathway to quantum electronics
Jul 26, 2024 (Nanowerk News) The key to developing quantum electronics may have a few kinks. According to a team led by researchers at Penn State, that’s not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers....
‘Miracle’ filter turns store-bought LEDs into spintronic devices
Jul 26, 2024 (Nanowerk News) Traditional electronics use semiconductors to transmit data through bursts of charged carriers (electrons or holes) to convey messages in “1s” and “0s.” Spintronic devices can process an order of magnitude more information by assigning binary code to the orientation of electrons’ magnetic poles, a property...
Fermi telescope finds new feature in brightest gamma-ray burst yet seen
Jul 26, 2024 (Nanowerk News) In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before. “A few minutes after the BOAT...
Graphene-quantum dot hybrid enables compact multispectral light detection
Jul 26, 2024 (Nanowerk Spotlight) Light detection across multiple wavelengths underpins numerous technological applications, from environmental monitoring to medical diagnostics. Traditional multispectral photodetectors, however, often rely on bulky components like beam splitters or interferometers, limiting their miniaturization potential. This constraint has long challenged researchers seeking to integrate advanced spectral sensing...
New laser technique could enable data storage on printable magnetic devices
Jul 26, 2024 (Nanowerk News) The proliferation of all things digital doesn’t mean that printing technology is no longer relevant. In fact, printing technology is required to make the semiconductors necessary for the digital world. And as an Osaka Metropolitan University-led team has shown using a new printing technique, printable...
Spin qubits go trampolining
Jul 26, 2024 (Nanowerk News) Researchers at QuTech developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group published their demonstration of hopping spins in Nature Communications and their work on somersaulting spins in Science. In 1998, Loss...
Mimicking cicada wings to destroy bacteria
Jul 25, 2024 (Nanowerk News) Trillions of periodical cicadas — several species of the genus Magicicada that emerge every 13 or 17 years — broke soil across the Eastern U.S. this summer. News outlets likened the event to Armageddon, an apocalypse or an invasion. But what about using words like...
Novel optical nanoscopy unveils ultrafast dynamics in nanomaterials
Jul 25, 2024 (Nanowerk News) Researchers from the University of California, Berkeley have developed cutting-edge nanoscale optical imaging techniques to provide unprecedented insights into the ultrafast carrier dynamics in advanced materials. Two recent studies, published in Advanced Materials ("Transient Nanoscopy of Exciton Dynamics in 2D Transition Metal Dichalcogenides") and ACS...
