Radiative cooling is a passive cooling technology that offers great promises to reduce space cooling cost, combat the urban island effect, and alleviate the global warming. To achieve passive daytime radiative cooling, current stateoftheart solutions often utilize complicated multilayer structures or a reflective metal layer, limiting their applications in many fields. Attempts have been ...

Next step of the reaction is the coprecipitation of radium and barium ions as sulphates, already present in the water (in case of radium, the reaction is not stoichiometric): Ba 2+ + Ra 2+ + 2SO 4 2→ BaRa(SO 2) 4. As a result of the latter reaction, small crystals of barium sulphate are formed, but they need a certain time for sedimentation.
