Jul 27, 2024 (Nanowerk News) An international team of scientists, including two researchers who now work in the Center for Advanced Sensor Technology (CAST) at UMBC, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon...
Discovery sheds light on the origins of matter in the early universe
Jul 27, 2024 (Nanowerk News) The early universe was 250,000 times hotter than the core of our sun. That’s far too hot to form the protons and neutrons that make up everyday matter. Scientists recreate the conditions of the early universe in particle accelerators by smashing atoms together at nearly...
novel tunable ultrasonic liquid crystal light diffuser
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...
