Abstract: A heat radiation device includes a heat source, a meta-material structure layer arranged on a front surface side of the heat source and configured to radiate radiant energy in a specific wavelength range by converting heat energy inputted from the heat source into the radiant energy in the specific wavelength range, and a rear-surface metal layer arranged on a rear surface side of the heat source. An average emissivity of the rear-surface metal layer is smaller than an average emissivity of the meta-material structure layer.

Abstract: A refining method according to the present invention is a refining method for crystallizing a compound with at least one crystal form, including: setting, as a target wavelength, a specific infrared wavelength at which a specific crystal form precipitates from a solution of the compound dissolved in a solvent; and using an infrared radiation apparatus capable of emitting infrared radiation including the target wavelength to evaporate the solvent and precipitate the specific crystal form while irradiating the solution with infrared radiation including the target wavelength. The specific infrared wavelength is preferably set as the target wavelength based on an infrared absorption spectrum of the crystal form and the dissolution rate of the compound in the solvent.

Abstract: An infrared heater 10 includes a heating element 40 that emits infrared radiation when heated and that is capable of absorbing infrared radiation in a predetermined reflection wavelength range, and a filter unit 50 that is disposed so as to be separated by a first space 47, which is open to an outside space, from the heating element 40. The filter unit 50 includes one or more transmission layers (a first transmission layer 51) that transmit at least a part of the infrared radiation from the heating element 40, and a reflective section (the first transmission layer 51) that reflects infrared radiation in the reflection wavelength range toward the heating element 40.

Abstract: An analysis apparatus includes: an acceptance unit adapted to accept parameters that affect precipitation of a crystal of an analyte; a prediction unit adapted to predict a type of crystal form to be precipitated, based on the accepted parameters; an evaluation unit adapted to evaluate a relationship between the type of crystal form to be precipitated and the parameters, based on a degree of influence that represents an extent to which each of the parameters affects the precipitation of the crystal of the analyte; and a providing unit that provides the type of crystal form to be precipitated and a precipitation condition to a user as information about a crystal form of a crystal to be precipitated. Thus, the type of crystal form to be precipitated and precipitation conditions of each crystal form can be predicted, with regard to an analyte that exhibits crystal polymorphism.

Abstract: A method for producing a reaction product, with which the reaction product is obtained from a starting material through a particular organic synthesis reaction, the method includes (a) a step of setting a target wavelength to a peak wavelength of a reaction region involved in the organic synthesis reaction in an infrared absorption spectrum of the starting material; (b) a step of preparing an infrared heater that emits an infrared ray having a peak at the target wavelength from a structure constituted by a metal pattern, a dielectric layer, and a metal substrate stacked in this order from an outer side toward an inner side; and (c) a step of obtaining the reaction product by allowing the organic synthesis reaction to proceed while the infrared ray having a peak at the target wavelength is being applied to the starting material from the infrared heater.
