Published Historic iceberg surges offer insights on modern climate change



A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.
Published New method makes hydrogen from solar power and agricultural waste



Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years



A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.
Published Researchers create materials with unique combo of stiffness, thermal insulation



Researchers have demonstrated the ability to engineer materials that are both stiff and capable of insulating against heat. This combination of properties is extremely unusual and holds promise for a range of applications, such as the development of new thermal insulation coatings for electronic devices.
Published Biobased building materials less sustainable than concrete in South Africa, experts find



Scientists have discovered that mycelium composites, biobased materials made from fungi and agricultural residues, can have a greater environmental impact than conventional fossil-fuel-based materials due to the high amount of electricity involved in their production.
Published Polymeric films protect anodes from sulfide solid electrolytes



Researchers unveil the interaction between polymeric materials and sulfide solid electrolytes.
Published 'The magic of making electricity from metals and air' The vexing carbonate has achieved it!



Team develops a high-energy, high-efficiency all-solid-state Na-air battery platform.
Published Charge your laptop in a minute or your EV in 10? Supercapacitors can help



Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes. New research could lead to such advances.
Published Controlling water, transforming greenhouse gases



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 Observing mammalian cells with superfast soft X-rays



Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Published Charting a pathway to next-gen biofuels



From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds



Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published New milestone for lithium metal batteries



Scientists develop a porous structures for lithium metal batteries.
Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere



Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
Published Producing novel liquid crystals by stacking antiaromatic units



In a recent study, researchers developed modified norcorrole molecules whose side chains favored the formation of columnar -stacking structures. Using these compounds, they produced liquid crystals with high electrical conductivity and thermotropic properties. Their findings open up new design avenues for materials useful in electronics, sensing, optics, and biomedicine.
Published Unlocking complex sulfur molecules: Novel approach for synthesis of functionalized benzenethiol equivalents



Organosulfur skeletons are crucial in many fields, including pharmaceuticals and electronics. Synthesizing organosulfur skeletons requires o-bromobenzenethiols. However, conventional methods face challenges due to quick oxidation and formation of highly reactive intermediates. Researchers have now developed a new method for synthesizing o-bromobenzenethiols from aryne intermediates via bromothiolation. This method can pave the way for the synthesis of new organosulfur compounds with applications in diverse fields.
Published Researchers design new metal-free porous framework materials



Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published Adhesive coatings can prevent scarring around medical implants



Engineers have found a way to eliminate the buildup of scar tissue around implantable devices, by coating them with a hydrogel adhesive. The material binds the device to tissue and prevents the immune system from attacking the device.
Published Promethium bound: Rare earth element's secrets exposed



Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes



In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
