A 3D photothermal cone was developed to optimize light harvesting via multiple reflections within rational morphology for high-efficiency solar-driven evaporation.

Cleaning up their act: A novel CO2‐stable and cobalt‐free dual‐phase membrane for oxygen separation from air has been developed that consists of 40 wt % NiFe2O4 and 60 wt % Ce0.9Gd0.1O2−δ. This membrane shows a steady oxygen permeation flux over 100 h using CO2 as sweep gas at 1000 °C.

A facile strategy based on a nanocomposite is developed to fabricate a rGO–MWCNT membrane for the improvement of photothermal evaporation.
