Ammonia synthesis by mechanocatalysis in a ball mill

A breakthrough in the fight against hunger, three Nobel Prizes, and 150 million tonnes of annual production—yet still a tricky topic for research: For over 100 years, the chemical industry has been using the Haber-Bosch ...

Tuning chemical reactions with light

The chemical industry consumes a lot of energy, not only to initiate reactions but also to separate products from by-products. In a promising emerging field of research, scientists worldwide are trying to use nanoscale antennas ...

Pyrrole chemistry: Good things come in threes

A new approach leads to the long-awaited formation of rings made of three pyrroles, which could be used to produce compounds with a host of interesting properties, and explains why they have not been observed before.

Induced-fit adsorbent for acetylene

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 ...

Sweet spot for membrane thickness offers sustainable separations

Super-thin carbon molecular sieve (CMS) membranes may not be best for separating industrially important chemical mixtures. However, ensuring the CMS film thickness is just right could enable more energy-efficient purification ...

Super-selective catalysts key to carbon conversion

Catalysts could prove to be the key to converting carbon dioxide and carbon monoxide into value-added products but their effectiveness depends on them being selective in how they work.
