Induced-fit adsorbent for acetylene

16-Aug-2021

We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an international team of researchers has now introduced a ...

Organic mixed valence pigments absorb in the near infrared

12-Aug-2021

In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. A team of chemists have now produced an unusual organic pigment, which is “switched on” by an electrical charge to become a potent dye that absorbs light in the near-infrared range. The team's ...

Economical synthesis of polyacrylates and polymethacrylates from biobased materials

22-Jul-2021

Despite the best efforts of industry to work towards sustainability, most plastics (or polymers) are still made using non-renewable fossil fuels. However, researchers have now found an economical method for producing biobased acrylate resins. The study, published in the journal Angewandte Chemie, ...

Amidation of light alkanes

21-Jul-2021

The carbon–hydrogen bonds in alkanes—particularly those at the ends of the molecules, where each carbon has three hydrogen atoms bound to it—are very hard to “crack” if you want to replace the hydrogen atoms with other atoms. Methane (CH4) and ethane (CH3CH3) are made up, exclusively, of such ...
