New method for activating Earth-abundant metal catalysts

(Phys.org)—Many industrially relevant reactions require either a precious metal catalyst or an Earth-abundant metal catalyst in a low oxidation state. A catalyst with a Fe(0) complex, for example, is a good catalyst for ...

New catalysts mimic human vision

Photoreceptors in vertebrates typically consist of two separate colourless parts: an organic pigment and a protein. Combined, they create a colourful, light-sensitive molecule called an iminium ion that triggers vision upon ...

Researchers develop a small-molecule switch to activate proteins

From growing teeth, bones, and tissue in skin and organs to creating enzymes and hormones, proteins are one of the most diverse and important elements of living organisms. But those varied purposes, along with the interconnectivity ...

Bendable crystals tie current thinking in knots

Queensland researchers have shown that single crystals, typically thought of as brittle and inelastic, are flexible enough to be bent repeatedly and even tied in a knot.

Chemists image basic blocks of synthetic polymers

Synthetic polymers are everywhere in our society—from nylon and polyester clothing to Teflon cookware and epoxy glue. At the molecular level, these polymers' molecules are made of long chains of monomer building blocks, ...
