Recently, single-atom catalysts (SACs) based on transition metals (TMs) have been identified as highly active catalysts with excellent atomic efficiency, reduced consumption of expensive materials, ...

This review uniquely provides an in-depth focus on the stability issues of single-atom nanozymes (SAzymes), covering multiple aspects such as metal atom clustering and active site loss, ligand bond ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
