  • Does complete solid-liquid separation improve uranium recycling?
  • Such complete solid-liquid separation (Fig. 4) facilitates our following recycle use to an ideal form, as evidenced by observation of no decrease in both uranium adsorption and adsorbent recovery from a 100 ppm uranium solution after repeating adsorption-desorption cycles (Fig. 4) for 11 times (Supplementary Fig. 4). Fig. 4: Our MOF routes.

  • Can bioinspired porous membrane remove uranium from seawater?
  • Yang, L. S. et al. Bioinspired hierarchical porous membrane for efficient uranium extraction from seawater. Nat. Sustain. 5, 71–80 (2025). Wang, Y. L. et al. Umbellate distortions of the uranyl coordination environment result in a stable and porous polycatenated framework that can effectively remove cesium from aqueous solutions. J. Am. Chem.
  • How can uranium separation methods be improved?
  • With the rapid development of nuclear energy, problems with uranium supply chain and nuclear waste accumulation have motivated researchers to improve uranium separation methods. Here we show a paradigm for such goal based on the in-situ formation of π - f conjugated two-dimensional uranium-organic framework.
