An express sensor to determine the toxicity of honey

Russian scientists at Ural Federal University (UrFU, Yekaterinburg) and the Institute of Organic Synthesis, Ural Branch of the Russian Academy of Sciences have created an express sensor for the detection of nitrobenzene in ...

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 ...

Solving the plastic shortage with a new chemical catalyst

In a year that has already battered manufacturing supply chains, yet another shortage is complicating manufacturers' and consumers' lives: plastics, and the food packaging, automotive components, clothing, medical and lab ...

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.
