Single-atom catalysts (SACs) have attracted extensive attention in the catalysis field because of their remarkable catalytic activity, gratifying stability, excellent selectivity, and 100% atom utilization. With atomically dispersed metal active sites, Fe-N-C SACs can mimic oxidase by activating O into reactive oxygen species, O • radicals. Taking advantages of this property, single-atom nanozymes (SAzymes) can become a great impetus to develop novel biosensors.

The twist angle strongly affects the electronic states, excitons and phonons of the twisted structures through interlayer coupling, giving rise to exotic optical, electric and spintronic behaviours. In twisted bilayer graphene, at certain twist angles, long-range periodicity associated with moiré patterns introduces flat electronic bands and highly localized electronic states, resulting in Mott insulating behaviour and superconductivity.

- Rational design of nonprecious metal catalysts for the oxygen evolution reaction (OER) is crucial for improving the water splitting process's efficiency and cost-effectiveness.
- Transition-metal-based nanomaterials, specifically Co P@Co/nitrogen-doped carbon (Co P@Co/N-C), are highlighted for their high activity, low cost, and robust performance, developed through a simple sugar-blowing method and low-temperature phosphorization.
- Co P@Co/N-C demonstrates superior OER performance compared to other alternatives, with significant stability and increased catalytic activity observed during testing, making it promising for broader applications, including methanol and glucose electrooxidation.
