Abstract: The disclosure is a cold storage material containing: a cold storage material main agent formed from water and a melting point adjuster; and a freezing point adjuster. The melting point adjuster includes a plurality of types of inorganic salts and an organic compound. Anions of the plurality of types of inorganic salts are all chlorine, and cations of the plurality of types of inorganic salts include at least sodium. The freezing point adjuster is a salt having a functional group that is identical to a cation included in any of the plurality of types of inorganic salts, and the salt has a temperature dependence of saturated solubility in pure water that decreases by 30% or more at a water temperature from 20° C. to 0° C.

Abstract: A method of treating an aqueous solution containing quantum dots, the method includes: a dissolution liquid preparation step of dissolving a quaternary ammonium salt and a potassium salt in an aqueous solution containing quantum dots to prepare a dissolution liquid; a phase separation step of heating the dissolution liquid to separate the dissolution liquid into two phases, which are a quaternary ammonium salt phase containing a large amount of the quaternary ammonium salt and a potassium salt phase containing a large amount of the potassium salt, and also to cause the quantum dots to be included in either one of the quaternary ammonium salt phase and the potassium salt phase; and a fractionation step of separating the quaternary ammonium salt phase and the potassium salt phase by fractionation.

Abstract: Provided is a latent heat storage material capable of keeping an object to be refrigerated, such as frozen food or ice cream, cold at a temperature of −20° C. or lower for a long period of time, and of reducing power consumption required at a time of solidification. The latent heat storage material contains 5 to 21 parts by weight of ammonium chloride, 2 to 13 parts by weight of potassium chloride, 5 to 23 parts by weight of urea, and 43 to 88 parts by weight of water. The total of the ammonium chloride, the potassium chloride, the urea, and the water is 100 parts by weight, and the latent heat storage material has a main melting point in a range from −20° C. to −23° C.
