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...
How to capture water from air with metal-organic frameworks
Jan 05, 2024 (Nanowerk News) Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Dresden University of Technology (TUD) have unraveled the water adsorption mechanism in certain microporous materials – so-called hierarchical metal-organic frameworks (MOFs) – while probing them on the atomic scale. Discovered only about 25 years ago, their special properties...
