Abstract: An encapsulated agent includes a central part and an outer part that covers a surface of the central part. The central part contains a viscosity-reducing material that reduces viscosity of a fluid to be used in a hydrofracturing technique. The outer part contains a plurality of particulate substances and a holding material that holds the plurality of particulate substances and enables gradual release of the central part in the fluid. The outer part involves distribution of the plurality of particulate substances that allows a content to have one or more local maxima in a direction away from the central part.

Abstract: An encapsulated agent includes: a central part 1; and an outer part 2 that covers a surface of the central part 1. The central part 1 contains a viscosity-reducing material that reduces the viscosity of a fluid to be used in a hydrofracturing technique. The outer part 2 enables gradual release of the central part 1 in the fluid, and contains a styrene-butadiene copolymer having glass-transition temperature that is equal to or higher than −20 degrees centigrade and equal to or lower than 80 degrees centigrade.

Abstract: Disclosed is a non-aqueous electrolyte secondary battery that is small and lightweight, has a high capacity, and can be produced without causing a size increase and a significant cost increase, wherein, even if an internal short circuit occurs, thermal runaway is unlikely to occur, and there is no risk of ignition or explosion. Also disclosed is is a method for suppressing thermal runaway caused by an internal short circuit, wherein sulfur-modified polyacrylonitrile is contained in a negative electrode material mixture layer in a non-aqueous electrolyte secondary battery that includes: a positive electrode that contains a positive electrode active material; a negative electrode that contains a negative electrode active material; and a non-aqueous electrolyte. The amount of sulfur-modified polyacrylonitrile can be set to 30 mass % or more.

Abstract: A converter includes a first electrode, a second electrode, a dielectric elastomer film, and a high-dielectric-constant film. The dielectric elastomer film is disposed between the first electrode and the second electrode, and has relative dielectric constant ε1. The high-dielectric-constant film is disposed at one or both of: a location between the first electrode and the dielectric elastomer film; and a location between the second electrode and the dielectric elastomer film. The high-dielectric-constant film has relative dielectric constant ε2 that is higher than the relative dielectric constant ε1.
