Published Direct view of tantalum oxidation that impedes qubit coherence
(via sciencedaily.com) Original source Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
Published In a warming world, climate scientists consider category 6 hurricanes
(via sciencedaily.com) Original source For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 -- 95 mph) to Category 5 (wind speeds of 158 mph or greater). But as increasing ocean temperatures contribute to ever more intense and destructive hurricanes, climate scientists wondered whether the open-ended Category 5 is sufficient to communicate the risk of hurricane damage in a warming climate.
Published A sleeker facial recognition technology tested on Michelangelo's David
(via sciencedaily.com) Original source Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.
Published Unveiling Oxidation-induced Super-elasticity in Metallic Glass Nanotubes
(via sciencedaily.com) Original source Oxidation can degrade the properties and functionality of metals. However, a research team recently found that severely oxidized metallic glass nanotubes can attain an ultrahigh recoverable elastic strain, outperforming most conventional super-elastic metals. They also discovered the physical mechanisms underpinning this super-elasticity. Their discovery implies that oxidation in low-dimension metallic glass can result in unique properties for applications in sensors, medical devices and other nanodevices.

Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators
(via sciencedaily.com) Original source Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Key dynamics of 2D nanomaterials: View to larger-scale production
(via sciencedaily.com) Original source A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
Published Death toll shows extreme air pollution events a growing urban threat
(via sciencedaily.com) Original source New research has estimated that 1454 avoidable deaths (one person every five days) occurred in Australian capital cities in the past 20 years because of fine particle air pollution from extreme events such as bushfires and dust storms, wood-heater smoke or industrial accidents.
Published Machine learning guides carbon nanotechnology
(via sciencedaily.com) Original source Carbon nanostructures could become easier to design and synthesize thanks to a machine learning method that predicts how they grow on metal surfaces. The new approach will make it easier to exploit the unique chemical versatility of carbon nanotechnology.
Published Unprecedented ocean heating shows risks of a world 3°C warmer
(via sciencedaily.com) Original source New research examines the causes of the record-breaking ocean temperatures witnessed in 2023.
Published Fungal-rich soil may improve green roofs
(via sciencedaily.com) Original source Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. But, in the U.S., green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A new study finds that managing green roof soil microbes boosts healthy urban soil development, which is a methodology that could be applied to support climate resilience in cities.
Published New breakthroughs for unlocking the potential of plasmonics
(via sciencedaily.com) Original source Plasmonics are unique light-matter interactions in the nanoscale regime. Now, a team of researchers has highlighted advances in shadow growth techniques for plasmonic materials, which have the potential to give rise to nanoparticles with diverse shapes and properties. They also introduce a method for large-scale production of nano-rotamers of magnesium with programmable polarization behavior, opening avenues for novel research applications.
Published Small yet mighty: Showcasing precision nanocluster formation with molecular traps
(via sciencedaily.com) Original source Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.

(via sciencedaily.com) Original source A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This development enables non-fading structural colors that do not depend on the viewing angle and can be printed. The material has a low environmental and biological impact and can be applied extremely thinly, promising significant weight improvements over conventional paints.
