Arifur Rahim, UNSW Sydney Catalysts are substances that can speed up chemical reactions, which is very important for industrial chemistry. However, for some reactions, platinum makes an excellent catalysts, but it … Read more

MIT Chemists Design New Light-Powered Catalysts That Could Aid in Manufacturing

MIT chemists have designed a new type of photoredox catalyst that could make it easier to incorporate light-driven reactions into continuous flow manufacturing processes. The polymer catalysts could be used to coat tubing and perform chemical transformations on reactants as they flow through the tube, as imagined in this digital artwork.

Molecular Machines: Bacteria-Killing Drills Get an Upgrade

The membranes of infectious bacteria are no match for molecular machines developed at Rice University. The machines are activated by visible light and drill into bacteria, killing them. The drills could also break down the microorganisms’ evolved resistance to antibiotics by letting the drugs in.

New Artificial Enzyme Shows Potential for New Renewable Energy Source

A new artificial enzyme has shown it can chew through lignin, the tough polymer that helps woody plants hold their shape. Lignin also stores tremendous potential for renewable energy and materials. New artificial enzyme breaks down tough, woody lignin. Research shows promise for developing a new renewable energy source. A new artificial enzyme has demonstrated … Read more

Science, Art, and Sustainability: How To Tie-Dye Cotton With Acorns and Rust

Tie-dyeing cotton fabric with acorn and rust solutions turns it brown, orange, blue, and black. Credit: Adapted from Journal of Chemical Education 2022, DOI: 10.1021/acs.jchemed.2c00086 Tie-dyeing is a fun activity that can spice up clothing, such as t-shirts, with colorful patterns. Although tie-dye kits are available to buy in stores, nature provides dyes that can … Read more

Möbius Carbon Nanobelt: A Möbius Strip Constructed Solely of Carbon Atoms

A new synthesis method creates a belt-shaped molecular nanocarbon with a twisted Möbius band topology, i.e., a Möbius carbon nanobelt. Credit: Issey Takahashi Scientists have constructed the first belt-shaped molecular nanocarbon with a twisted Möbius band topology—a Möbius carbon nanobelt—that paves the way for the development of nanocarbon materials with complex topological structures. Obtaining structurally … Read more

Ground-Breaking Experiments: Tracking Chirality in Real Time

Artist’s impression of a time-resolved circular dichroism measurement of a photoexcited spin-crossover complex. Credit: Ella Maru Studio, Inc. Chiral molecules exist in two forms known as enantiomers, which are mirror images of each other and non-superposable – much like a pair of hands. While most chemical and physical properties are shared, enantiomers can have adverse … Read more

How Three Mutations Work Together To Spur New COVID-19 Variants

The researchers tested how three mutations altered the interaction between a key part of the virus (gray) and the human protein to which it attaches (orange). Credit: Adapted from Biochemistry 2022, DOI: 10.1021/acs.biochem.2c00132 Like storm waves battering a ship, new versions of the SARS-CoV-2 virus, which causes COVID-19, have buffeted the world one after another. … Read more

Everyday Plastic Products – Such As Coffee Cups – Release Trillions of Microscopic Particles Into Water

NIST researchers analyzed single-use beverage cups, equivalent to espresso cups, which might launch trillions of nanoparticles, or tiny plastic particles, from the internal lining of the cup when the water is heated. Credit score: N. Hanacek/NIST Plastics are throughout us, whether or not it’s the grocery baggage we use on the grocery store or home … Read more
