1+ day, 3+ hour ago  (856+ words) Hydrogels are squishy, bio-friendly materials that are made mostly of water and a bit of polymer. The Jell-O-like substance is available in the form of medical patches, sprays, and glues, and can be stuck to the skin or implanted in…...

1+ mon, 1+ week ago  (485+ words) Published in Nature Communications, the study uncovers a series of hidden intermediate stages that appear when molecules are heated to become materials. Capturing these intermediates opens a new way to discover and design materials that aren’t accessible through typical synthetic…...

1+ mon, 1+ day ago  (555+ words) With help from a novel cross-linking molecule, MIT chemists have shown they can substantially improve the ballistic impact resistance of common polymers, including polystyrene and a type of rubber used to make shoe soles. To make the polymer more resistant…...

1+ mon, 6+ day ago  (786+ words) Industrial oxidation chemistry is a cornerstone of modern manufacturing, accounting for nearly one-third of all chemical industrial processes. While essential for making pharmaceuticals, dyes, and many specialty chemicals, industrial oxidation typically relies on high-temperature, high-pressure processes involving toxic oxidizing agents....

1+ mon, 6+ day ago  (364+ words) Alloying is a powerful method for achieving this goal. In this regard, a key challenge is asymmetric alloying, which introduces asymmetry into the metal cluster by selectively placing heterometal atoms at non-equivalent sites, desymmetrizing the cluster and therefore imparting chirality-associated…...

1+ mon, 5+ day ago  (669+ words) The safety data sheet has been a constant in chemical hazard communication for decades. Its 16-section format, standardized under the Globally Harmonized System, has provided a recognizable framework for conveying hazard information across industries and borders. What has changed considerably…...

1+ mon, 1+ week ago  (417+ words) The study, published in Advanced Materials, represents a new processing approach for wurtzite III-V nitrides, a class of semiconductors already widely used in microelectronics but whose ferroelectric potential has only been recognized since 2019. Ferroelectric materials possess a built-in electric polarization…...

1+ mon, 3+ week ago  (534+ words) In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns that can deform and melt, opening new pathways for neuromorphic computing and superconductors, University of Michigan Engineering researchers have found. “Metallurgists…...

1+ mon, 3+ week ago  (664+ words) The new technique uses a sophisticated set of algorithms to direct an electron beam at a target atom with a precision of a few picometers (one trillionth of a meter). Illustration by the researchers / MIT But existing techniques can only…...

2+ mon, 1+ day ago  (380+ words) A team using neutrons at Oak Ridge National Laboratory discovered that spin waves in hematite, essentially rust, show a clear separation in energy, a unique signature that confirms the material’s altermagnetic nature — ideal conditions for spintronics.
