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.

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.

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.

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.

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.

More electricity from the sun      (via sciencedaily.com)     Original source 

A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.

What no one has seen before -- simulation of gravitational waves from failing warp drive      (via sciencedaily.com)     Original source 

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.

Organic nanozymes have broad applications from food and agriculture to biomedicine      (via sciencedaily.com)     Original source 

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

Plant-inspired polymers for water purification      (via sciencedaily.com)     Original source 

Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
