Provided is a water vapor adsorption-desorption material in which a substance having a LCST is uniformly retained inside pores of a mesoporous body, which can reduce energy required for regeneration, and a method for measuring LCST behavior capable of measuring LCST behavior of an ionic liquid used in the water vapor adsorption-desorption material without errors. The water vapor adsorption-desorption material includes a mesoporous body and an ionic liquid retained inside pores of the mesoporous body, the ionic liquid exhibiting LCST behavior, and the method for measuring LCST behavior of an ionic liquid used for a water vapor adsorption-desorption material, the method including detecting a change of hydration/dehydration state of a mixture of the ionic liquid and water as electric signals, by means of AC impedance measurement.

Provided is a temperature-responsive hygroscopic material having a hygroscopic property that varies widely according to temperature variation and a method for producing the temperature-responsive hygroscopic material. The temperature-responsive hygroscopic material includes a mesoporous body having an average pore diameter of 2 nm to less than 50 nm and a temperature sensitive molecule chemically bonded with the mesoporous body inside a pore of the mesoporous body. The method includes a step of causing, in a solvent including an activator and a coupling agent, a coupling reaction of: a mesoporous body having an average diameter of 2 nm to less than 50 nm and having a functional group on a surface thereof; and a temperature sensitive molecule having a functional group which can undergo a coupling reaction with the functional group on the surface of the mesoporous body.

A method of production of core/shell type nanoparticles includes the following steps: a first step of applying a first power to cause the generation of the plasma so as to selectively cause the precipitation of a first metal so as to form nanoparticles as cores and a second step of applying a second power which is larger than the first power to cause the generation of the plasma so as to cause the precipitation of a second metal which has a smaller oxidation reduction potential than the first metal on the core surface so as to form shells which are comprised of the second metal which cover the cores which are comprised of the first metal.
