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 ...

Another atom-swapping reaction has entered the ring. Yoonsu Park and his team at the Korea Advanced Institute of Science and Technology (KAIST) have devised a light-driven reaction that replaces an ...

Fe-N 4 is a typical active site in Fe-N/C catalysts with maximum atomic utilization and a well-defined structure. However, its high symmetry limits further electronic structure optimization and ...
