Ammonia is essential for global agriculture, but its production via the Haber-Bosch process is energy-intensive and emits vast amounts of CO₂. Electrocatalytic nitrogen reduction offers a greener alternative, yet breaking nitrogen’s stubborn triple bond under mild conditions has remained a major hurdle. Now, researchers have introduced a conceptually novel mechanism—hydroxide-activated…
New antiperovskite-supported cobalt catalyst can produce ammonia from nitrogen and hydrogen under mild conditions without precious metals, as reported by researchers from Science Tokyo. This self-organizing nanostructured…
Density functional theory calculations reveal how the α-Ag2WO4 (110) surface turns H2O2 and H2O into a burst of reactive oxygen species (ROS) — a ‘ROS storm’ — over energy barriers below 0.2 eV. Electronic states inside the band…

Using just a zeolite as a catalyst, in the presence of water, scientists produced two carboxylic acids through carbonylation—the introduction of carbon monoxide into a molecule. Industrially relevant products, propanoic acid is…
Varying the cobalt-to-iron ratio in CoₓFe₃₋ₓO₄ nanoparticles shifts crystal phase, magnetic coercivity, pellet magnetostriction, and MCF-7 breast cancer cell growth inhibition, with the strongest strain at x = 0.7 and the greatest zero-field cytotoxicity at x = 1.0 and 1.1.
Strain engineering can alter a material’s properties without changing its chemical composition, but applying it to amorphous materials can cause crystallization or mechanical damage. As reported in Advanced Photonics, researchers…
Newswise — A Korean research team has developed a transfer printing process that enables solid electrolytes, a key component of solid-state batteries, to be fabricated as very thin, uniform, and defect-free layers over large areas. The technology is expected to provide a foundation for the large-area manufacturing of high-energy-density solid-state…
Aqueous Zn-I2 batteries are safe and low-cost, but soluble I2 species can shuttle to the Zn anode and shorten cycle life. Researchers found that hydroxyl functional groups on self-supporting carbon nanotube cathodes strongly…
