Chemists offer two new methods to develop a way to easily replace a carbon atom with a nitrogen atom in a molecule. The findings could make it easier to develop new drugs. For years, if you asked the ...

An unconventional route for modifying pharmaceutically relevant molecules swaps an atom of carbon for one of nitrogen. The resulting derivatives might open up avenues of research in ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

As a graduate student at the University of California, Berkeley, Mark Levin started sketching out ideas for how to do something no chemist had ever managed before: swapping one of the carbon atoms in ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...

A team in Milan has developed a first-of-its-kind single-atom catalyst that acts like a molecular switch, enabling cleaner, more adaptable chemical reactions. Stable, recyclable, and eco-friendly, it ...

Three chemists who predicted and were first to make quantum dots — nanoscale crystals that interact with light in unusual ways — have been awarded the Nobel Prize in Chemistry. Moungi Bawendi at the ...

Morphine is one of the most famous natural products in the world and the progenitor of many semisynthetic opioids, such as heroin and oxycodone, as well as the overdose-reversing drug naloxone. Most ...
