Published AI approach elevates plasma performance and stability across fusion devices
(via sciencedaily.com) Original source Fusion researchers have successfully deployed machine learning methods to suppress harmful plasma edge instabilities without sacrificing plasma performance.
Published Innovative demand strategies for clean energy
(via sciencedaily.com) Original source A perspective piece describes innovative strategies that significantly reduce both resource consumption and fossil fuel emissions.
Published Wind farms are cheaper than you think -- and could have prevented Fukushima, says global review
(via sciencedaily.com) Original source Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy.
Published Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma
(via sciencedaily.com) Original source A new model for ballooning instabilities in apple-shaped fusion vessels considers the height and width of the plasma's edge.
Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published Breakthrough discovery uses engineered surfaces to shed heat
(via sciencedaily.com) Original source Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface. The temperature at which this phenomenon, called the Leidenfrost effect, occurs is predictable, usually happening above 230 degrees Celsius. A team has now discovered a method to create the aquatic levitation at a much lower temperature.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published Magnetic imprint on deconfined nuclear matter
(via sciencedaily.com) Original source Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published Studying bubbles can lead to more efficient biofuel motors
(via sciencedaily.com) Original source By studying how bubbles form in a drop of biodiesel, researchers can help future engines get the most energy out of the fuel.
Published Much more than a world first image of radioactive cesium atoms
(via sciencedaily.com) Original source Thirteen years after the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (FDNPP), a breakthrough in analysis has permitted a world first: direct imaging of radioactive cesium (Cs) atoms in environmental samples.
Published The case for sharing carbon storage risk
(via sciencedaily.com) Original source Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.
Published The price tag of phasing-out coal
(via sciencedaily.com) Original source Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.
Published New Nevada experiments will improve monitoring of nuclear explosions
(via sciencedaily.com) Original source On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published Methane emissions from landfill could be turned into sustainable jet fuel in plasma chemistry leap
(via sciencedaily.com) Original source Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.
Published Atomic nucleus excited with laser: a breakthrough after decades
(via sciencedaily.com) Original source For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
Published Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
(via sciencedaily.com) Original source Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.
Published Major milestone reached for key weapons component
(via sciencedaily.com) Original source Scientists have completed a crucial weapons component development milestone, prior to full rate production.
Published New beta-decay measurements in mirror nuclei pin down the weak nuclear force
(via sciencedaily.com) Original source Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process of nuclear beta decay. The research found that the properties of the beta decays of lithium-8 and boron-8 are in perfect agreement with the predictions of the Standard Model.
Published Coal train pollution increases health risks and disparities
(via sciencedaily.com) Original source The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.
Published Creating an island paradise in a fusion reactor
(via sciencedaily.com) Original source In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers have shown how two old methods can be combined to provide greater flexibility.
