  • Patent number: 8026459
    Abstract: A laser surface treatment for reducing reflection loss on the surface of an optical material is provided. A metal film is formed on the surface of the optical material, and then the metal film is removed from the optical material by irradiation of an ultra-intense short-pulse laser beam having a pulse width of 1 femtosecond to 100 picoseconds, so that a fine periodic structure is formed on the surface of the optical material exposed by the removal of the metal film. The obtained fine periodic structure has asperities with a periodic interval of preferably 50 to 1000 nm, which can be controlled by changing the laser energy density.

  • Publication number: 20110212185
    Abstract: Disclosed is a method of preventing diseases in plants which can bring about a redox reaction in the inside of plant cells thus inducing the expression of pathogen-resistance genes in the plant cells. There is no possibility that residual contents remain in soils. It is also possible to cultivate plants which are strong against diseases. By bringing water which contains reactive oxygen species and allows the reactive oxygen species to be held and to function for a long period into contact with plants, the expression of the pathogen-resistance genes which the plants possess is induced. Accordingly, the water containing reactive oxygen is absorbed into the plants to prevent diseases in plants.

  • Publication number: 20090297408
    Abstract: In the formation of an oxide film on an aluminum fiber, it has been difficult to form a thick alumina coating film on the aluminum fiber which already has a natural oxide film formed thereon. To overcome this problem, there is provided a method for forming an alumina coating film which enables the deep penetration of oxygen into an aluminum fiber by employing a three-stage heating treatment and an alumina fiber formed by the method. Also provided is a system for producing water by photocatalytic reaction, in which a photocatalyst comprising the alumina fiber coated with titania is irradiated with light from a light source to generate an active oxygen species, diffusing the active oxygen species in water to impart the function of the active oxygen species to water. The system can perform washing by utilizing an oxidation reaction with the resulting water. Further, provided is a gas treatment system which comprises the alumina fiber coated with titania to impart a photocatalytic function to the aluminum fiber.
