Chinese scientists have developed a new, eco-friendly method for carbonylation — a century-old chemical reaction essential for manufacturing everyday products like medicines, food preservatives and cosmetics. The breakthrough, published in the journal Nature on Oct 21, offers a cleaner, cheaper and more efficient way to transform basic chemicals into high-value…
Home → Features → Natural Sciences → Physics → Matter and Energy A 400-year-old glass paradox still teaches scientists how brittle materials fail. Prince Rupert’s drops are tadpole-shaped pieces of glass. But they don’t behave at all like you’d expect. Strike the fat end with a hammer and, astonishingly, the…
The approach drastically improved capacity: a slurry mix with 4 Molar (M) MnO₂ achieved a soluble manganese concentration of 3.76 M. A new strategy boosts the battery storage capacity of Mn-based semi-solid batteries by 400 percent over the traditional ones. The approach drastically increased the active material concentration in electrolytes…
EBSD mapping used a Symmetry S2 detector (Oxford Instruments) and TEM imaging was conducted on a JEM-2100F (JEOL). High-resolution STEM imaging was performed using the FEI Themis Z microscope equipped with an EDS detector. Atomic-resolution chemical characterization with compositional mapping was performed using four in-column Super-X silicon drift detectors. For…
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…
Hydrogen could help industries reduce their dependence on fossil fuels, but its environmental benefits depend largely on how it is produced. Conventional hydrogen production can release substantial amounts of greenhouse gases…
