Sequential anaerobic-aerobic photocatalytic degradation of halogenated organic pollutants via dual-site confined carbon nitride.

Solar-driven photocatalytic dehalogenation and mineralization of halogenated organic pollutants (HOPs) remain a significant challenge. In this study, we develop a dual-site confined g-CN (CN)-based catalyst, incorporating cerium doping and nitrogen vacancies (Ce-FCNV), for a sequential anaerobic-aerobic photocatalytic system designed for the deep treatment of HOPs-contaminated wastewater. The Ce-FCNV catalyst demonstrates a remarkable 36.

Vortex phase-based adaptive moiré technique accommodating micro displacement measurement of freeform surfaces.

The traditional displacement measurement interferometer (DMI) provides elegant performance by straight interference fringe movement counting to convert a phase calculation into an image motion calculation. However, it cannot be applied to a curve surface displacement measurement. The counting of the movement of irregular fringes is not achievable.
