A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study, published in ...

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

Researchers at the University of Oklahoma have developed a breakthrough method of adding a single nitrogen atom to molecules, unlocking new possibilities in drug research and development. Now ...

One small atom can make a big difference in a molecule’s pharmacological properties. Especially if that atom is a nitrogen. Chemists at the University of Oklahoma have now unveiled a new strategy for ...

Multi-titanium hydrides can selectively snip the strong structural bonds of stable organic molecules called pyridines, RIKEN researchers have shown. This discovery could guide designing catalysts for ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

A copper-nickel dual-atom material reported in Nature Communications converts carbon dioxide into carbon monoxide at high temperatures with near-perfect selectivity, while resisting the structural ...

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 ...

A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling nanoscale sensing in spaces too tight for conventional optics.
