Published 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.
Published The corona is weirdly hot: Parker Solar Probe rules out one explanation
(via sciencedaily.com) Original source By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.
Published Dark matter: A camera trap for the invisible
(via sciencedaily.com) Original source AI-powered image recognition could give researchers a new tool in hunt for dark matter.
Published Robotics: Self-powered 'bugs' can skim across water to detect environmental data
(via sciencedaily.com) Original source Researchers have developed a self-powered 'bug' that can skim across the water, and they hope it will revolutionize aquatic robotics.
Published New additive process can make better -- and greener -- high-value chemicals
(via sciencedaily.com) Original source Researchers have achieved a significant breakthrough that could lead to better -- and greener -- agricultural chemicals and everyday products. Using a process that combines natural enzymes and light, the team developed an eco-friendly way to precisely mix fluorine, an important additive, into chemicals called olefins -- hydrocarbons used in a vast array of products, from detergents to fuels to medicines. This groundbreaking method offers an efficient new strategy for creating high-value chemicals with potential applications in agrochemicals, pharmaceuticals, renewable fuels, and more.
Published New understanding of fly behavior has potential application in robotics, public safety
(via sciencedaily.com) Original source Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.
Published Fresh light on the path to net zero
(via sciencedaily.com) Original source Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.
Published Pioneering measurement of the acidity of ionic liquids using Raman spectroscopy
(via sciencedaily.com) Original source A study has made it possible to estimate experimentally the energy required to transfer protons from water to ionic liquids.
Published NASA's Fermi finds new feature in brightest gamma-ray burst yet seen
(via sciencedaily.com) Original source In October 2022, astronomers were stunned by what was quickly dubbed the BOAT -- the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope reveals a feature never seen before.
Published 'Miracle' filter turns store-bought LEDs into spintronic devices
(via sciencedaily.com) Original source Scientists transformed existing optoelectronic devices into ones that can control electron spin at room temperature, without a ferromagnet or magnetic field. Researchers replaced the electrodes of store-bought LEDs with a patented spin filter made from hybrid organic-inorganic halide perovskite.
Published Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe's alchemy laboratory
(via sciencedaily.com) Original source Danish Tycho Brahe was most famous for his contributions to astronomy. However, he also had a well-equipped alchemical laboratory where he produced secret medicines for Europe's elite.
Published Indoor solar cells that maximize the use of light energy
(via sciencedaily.com) Original source Chemists have synthesized materials that can improve solar elements for indoor use. Such photovoltaic cells, which can also be integrated into various electronic devices, generate electricity even in low-light conditions.
Published Space-trekking muscle tests drugs for microgravity-induced muscle impairment
(via sciencedaily.com) Original source A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky to the International Space Station National Laboratory. These chips would help her better understand muscle impairment, often seen in astronauts and older adults, and test drugs to counter the condition.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Better way to produce green hydrogen
(via sciencedaily.com) Original source Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Tackling industrial emissions begins at the chemical reaction
(via sciencedaily.com) Original source Researchers are proposing a new way to curb industrial emissions, by tapping into the 'atomic intelligence' of liquid metals to deliver greener and more sustainable chemical reactions.
Published Researchers discover faster, more energy-efficient way to manufacture an industrially important chemical
(via sciencedaily.com) Original source The reactivity of zirconium on silicon nitride enhances the conversion of propane into propylene, a key commodity chemical needed to make polypropylene. This finding hints at the reactivity researchers might achieve with other nontraditional catalysts.
Published Researchers develop innovative battery recycling method
(via sciencedaily.com) Original source A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published Dark matter flies ahead of normal matter in mega galaxy cluster collision
(via sciencedaily.com) Original source Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.
Published A single-molecule-based organic porous material with great potential for efficient ammonia storage
(via sciencedaily.com) Original source Novel porous crystalline solid shows promise as an efficient and durable material for ammonia (NH3) capture and storage, report scientists. Made through a simple reprecipitation process, the proposed organic compound can reversibly adsorb and release NH3 via simple pressurization and decompression at room temperature.
