Reduced graphene oxide (RGO)–Fe₃O₄ composites with obviously enhanced microwave absorption properties were successfully fabricated by a rational one-pot simplified co-precipitation route, which avoided the usage of an inert gas and any additional chemical agents (such as surfactants and stabilizers).

Fluorescent nitrogen-doped carbon nanoparticles (FNCPs) were synthesized by one-pot hydrothermal treatment of strawberry juice. The strategy was simple, green, and low-cost. The as-prepared FNCPs showed some excellent properties such as water-soluble and good stability, which was applied as an Hg²⁺ sensor with high sensitivity and selectivity.

An ionic liquid assisted one-step route was developed to prepare metal-free P-doped graphene nanosheets (P-TRG) by thermal annealing a homogeneous mixture of graphene oxide and BmimPF₆.
