    摘要: The invention relates to a method for forming a transparent conductive thin film of In2O3—SnO2 on a surface of a plastics substrate of less heat resistance other than that of glass, ceramics, etc. When an In2O3—SnO2 precursor sol is produced by hydrolyzing and polymerizing a solution containing indium alkoxide and tin alkoxide, either tri-s-butoxyindium or tri-t-butoxyindium is used as the indium alkoxide. Water is added to the solution containing indium alkoxide and tin alkoxide at a temperature of not higher than −20° C. The obtained In2O3—SnO2 precursor sol is applied to a surface of a substrate to form a gel film, then the gel film is either irradiated with an ultraviolet beam of which wave length is not longer than 360 nm, or irradiated with an ultraviolet beam of which wave length is not longer than 260 nm and further irradiated with a laser beam of which wave length is not longer than 360 nm, to crystallize the gel forming the thin film, whereby an In2O3—SnO2 thin film having a conductivity is formed on the surface of the substrate.

    摘要: Methods, compositions and kits for masking and subsequent removal of oil, grease, rust and other stains from a variety of rough solid surfaces, including, but not limited to stone, concrete, asphalt, stucco brick, and ceramic. The methods include coating the stains with an opaque or translucent thin film of a composition that makes the stain practically indistinguishable against the background, exposing the coated stain to the elements, such as, sunlight, air, moisture, resulting in spontaneous transformation, degradation and subsequent removal of the stains from the solid surfaces. The compositions include a photocatalyst by itself or the photocatalyst combined with at least one of, a sensitizer, a dopant, a mediator, a co-reagent, a pigment and a binder. The role of a photocatalyst is to produce highly reactive species or radicals and initiate the degradation of a stain upon exposure to elements, such as, sunlight, air and ambient humidity. Artificial light sources can be used instead of sunlight.
