Abstract: A sound wave generator is configured to generate ultrasonic waves having a predetermined frequency that chases away vermin. The sound wave generator includes a power supply, a switch, an oscillation circuit, and a speaker. The power supply includes a battery that is a DC power supply and outputs DC power for generating sound waves. The switch is operated by a user of the sound wave generator to switch between supply and non-supply of power from the power supply to the oscillation circuit. When the switch is turned on, the oscillation circuit operates with DC power output from the power supply and oscillates an electrical signal having a predetermined frequency. An organic transistor is used in the oscillation circuit. The speaker converts the electrical signal oscillated by the oscillation circuit into sound waves and outputs the sound waves.

Abstract: A metal-air battery includes: a cathode formed of a co-continuous body having a three dimensional network structure formed by an integrated plurality of nanostructures having branches; a foil- or plate-like anode formed of a metal; a separator that absorbs a liquid, which is to be an electrolytic solution; and a foil- or plate-like current collector formed of a metal. The metal-air battery is formed with a wound structure in which the current collector, the cathode, the separator, the anode, and the separator are superimposed and wound in this order.

Abstract: A protein template is added to a solution in which metal ions of iron and copper are dissolved to introduce the metal ions into the protein template; the protein template is separated from metal ions that have not been incorporated in the protein template; the metal ions that have been incorporated in the protein template are reduced to obtain a protein containing alloy nanoparticles of iron and copper; a sol or gel in which a co-continuous body is dispersed is frozen; the frozen sol or gel is dried in a vacuum to obtain a porous body; the porous body is allowed to support the alloy nanoparticle containing protein; and the protein is removed.
