(via sciencedaily.com) Original source Researchers report that they have fabricated the world's highest-performing high-temperature superconducting wire segment while making the price-performance metric significantly more favorable.
Published New device for on-the-spot water testing
(via sciencedaily.com) Original source Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.
Published Researchers dig deeper into stability challenges of nuclear fusion -- with mayonnaise
(via sciencedaily.com) Original source Researchers are using mayonnaise to study and address the stability challenges of nuclear fusion by examining the phases of Rayleigh-Taylor instability. Their innovative approach aims to inform the design of more stable fusion capsules, contributing to the global effort to harness clean fusion energy. Their most recent paper explores the critical transitions between elastic and plastic phases in these conditions.
Published Advanced chelators offer efficient and eco-friendly rare earth element recovery
(via sciencedaily.com) Original source The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.
Published Concept for efficiency-enhanced noble-metal catalysts
(via sciencedaily.com) Original source The production of more than 90 percent of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible at all without catalysts. Researchers developed a concept that increases the stability of noble-metal catalysts and requires less noble metal for their production.
Published Heating for fusion: Why toast plasma when you can microwave it!
(via sciencedaily.com) Original source Can plasma be sufficiently heated inside a tokamak using only microwaves? New research suggests it can! Eliminating the central ohmic heating coil normally used in tokamaks will free up much-needed space for a more compact, efficient spherical tokamak.
Published Engineers develop general, high-speed technology to model, explain catalytic reactions
(via sciencedaily.com) Original source A research team developed artificial intelligence technology that could find ways to improve researchers' understanding of the chemical reactions involved in ammonia production and other complex chemical reactions.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source
(via sciencedaily.com) Original source Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.
Published Novel ultrafast electron microscopy technique advances understanding of processes applicable to brain-like computing
(via sciencedaily.com) Original source A team developed a new microscopy technique that uses electrical pulses to track the nanosecond dynamics within a material that is known to form charge density waves. Controlling these waves may lead to faster and more energy-efficient electronics.
Published Cold antimatter for quantum state-resolved precision measurements
(via sciencedaily.com) Original source Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before -- and thus identify possible matter-antimatter asymmetries. They have developed a trap, which can cool individual antiprotons much more rapidly than in the past.
Published Precise package delivery in cells?
(via sciencedaily.com) Original source Researchers have developed new real-time microscopy technology and successfully observed the behavior of 'motor proteins', which may hold the key to unraveling the efficient material transport strategy of cells.
Published Stacked up against the rest
(via sciencedaily.com) Original source Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.
Published Sustainable catalysts: Crystal phase-controlled cobalt nanoparticles for hydrogenation
(via sciencedaily.com) Original source Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, scientists report. Produced via an innovative hydrosilane-assisted synthesis method, these phase-controlled reusable nanoparticles enable the selective hydrogenation of various compounds under mild conditions without the use of harmful gases like ammonia. These efforts could lead to more sustainable and efficient catalytic processes across many industrial fields.
