A new device could be implanted into the human body to treat diabetes and obesity without the need for drugs or insulin A wireless electronic implant that clears excess glucose directly from the bloodstream could offer a drug-free way to manage type 2 diabetes and obesity, according to a landmark…
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…
We’re sharing this article early to provide faster access to peer-reviewed, accepted research. It is citable and carries a permanent DOI. This version is subject to further edits and will be replaced automatically by the final…
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 — Understanding how ions move through solid materials is key to advancing technologies such as batteries, fuel cells and sensors. A team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has demonstrated a cutting-edge method for gauging the activity of ions, revealing a new…
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…
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…
Comparing potassium hydride- and hydroxide-promoted iron catalysts shows hydride and proton hydrogen reach ammonia by different routes, and the hydride route is about six times faster Credit: Wang P., Gao W., Deng Y., et al.…
