Jan 08, 2024 (Nanowerk News) Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in...
Bacteriophage-powered micromotors for rapid and selective Point-of-Care bacteria detection (w/video)
Jan 08, 2024 (Nanowerk Spotlight) Misdiagnosis and delayed treatment of bacterial infections have long challenged medicine, contributing to antibiotic resistance and poor patient outcomes. Clinicians lack rapid, selective diagnostic tests to target narrow-spectrum antibiotics early in illness. Instead, imprecise broad-spectrum regimens remain routine despite fueling resistance. Recent advances offer new...
New crystal structure makes hydrogen fuel production more efficient and long-lasting
Jan 08, 2024 (Nanowerk News) Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a crucial challenge. A research team led by scientists from City University of Hong...
Three iron rings in a planet-forming disk
Jan 08, 2024 (Nanowerk News) The origin of Earth and the Solar System inspires scientists and the public alike. By studying the present state of our home planet and other objects in the Solar System, researchers have developed a detailed picture of the conditions when they evolved from a disk...
Substitutional doping of two-dimensional semiconductor for broadband photodetector
Jan 08, 2024 (Nanowerk News) Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In the realm of three-dimensional (3D) monocrystalline silicon, for instance, the introduction of boron (B) and nitrogen (N) atoms...
Attosecond breakthrough transforms understanding of electron movement
Jan 05, 2024 (Nanowerk News) A German-Swedish team has succeeded in simultaneously studying the rapid motion of electrons with high spatial accuracy and a temporal resolution in the attosecond range. Key Takeaways A breakthrough in tracking electron dynamics with unprecedented spatial and temporal resolution using photoemission electron microscopy and attosecond...
Engineers invent octopus-inspired technology that can deceive and signal
Jan 05, 2024 (Nanowerk News) With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers at the University of California, Irvine have drawn inspiration from this natural wonder to develop...
New images reveal what Neptune and Uranus really look like
Jan 06, 2024 (Nanowerk News) Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought. The correct shades of the planets have been confirmed with the help...
Polarization-independent liquid-crystal phase modulators
Jan 05, 2024 (Nanowerk News) Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, light weight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization-sensitive, meaning that they affect the phase of light differently depending on its...
Low-cost microscope projection photolithography system for below 100 nm high-resolution fabrication
Jan 05, 2024 (Nanowerk News) Integrated optical signal distributing, processing, and sensing networks require the miniaturization of basic optical elements, such as waveguides, splitters, gratings, and optical switches. To achieve this, fabrication approaches that allow for high-resolution manufacturing are required. Curved elements like bends and ring resonators are especially challenging...
