Abstract: Provided is a perfuming method including applying a water-based product to a fabric or a human body and drying, the water-based product containing a perfume precursor composed of an ester of at least one perfume selected from maltol, ethyl maltol, vanillin, ethyl vanillin, and raspberry ketone and at least one aliphatic monocarboxylic acid or aliphatic dicarboxylic acid selected from lauric acid, myristic acid, palimitic acid, stearic acid, oleic acid, adipic acid, and sebacic acid; and subsequently bringing the perfume precursor into contact with moisture in the air to perform hydrolysis, thereby releasing a perfume.

Abstract: Disclosed is a method of producing a barium-titanium-based ferroelectric glass using a containerless solidification process, such as an electrostatic levitation process or a gas levitation process, which comprises the steps of levitating a sample 1 of a barium-titanium-based compound by a levitating force of compressed air, heating the sample up to a temperature greater than its melting point (1330° C.) by about 100° C. to allow the sample to be molten, and, after maintaining the molten state for a given time period (at least several second), quenching the sample from a given temperature range (1400 to 1000° C.) at a cooling rate of about 103 K/sec, so as to allow the sample to be solidified while inhibiting nucleation and mixing of impurities from a container. The present invention makes it possible to provide a glass exhibiting an unprecedented, extremely large permittivity.

Abstract: An optical element of the present invention exhibits at least one of an upconversion emission characteristic and a light amplifying characteristic when irradiated with an excitation light. The optical element includes a bulk glass that contains titanium oxide as a main component, and the glass further contains a rare earth element. As the rare earth element, at least one element of Er and Yb, or a combination of Yb and Tm preferably is used, for example.
