Described is a doping technique that forms a stable amorphous silicon film and a stable polycrystalline silicon film at a low temperature and simultaneously that imparts conductivity in an atmospheric pressure environment. A method for producing a compound containing a bond between different elements belonging to Group 4 to Group 15 of the periodic table, the method including: applying, at a low frequency and atmospheric pressure, high voltage to an inside of an electric discharge tube obtained by attaching high-voltage electrodes to a metal tube or an insulator tube or between flat plate electrodes while passing an introduction gas, so as to convert molecules present in the electric discharge tube or between the flat plate electrodes into a plasma; and applying the plasma to substances to be irradiated, the substances to be irradiated being two or more elementary substances or compounds.

The present application relates to a device for treating skin using non-thermal plasma. It comprises a housing having a skin interface electrode for application to skin during treatment, a generator for generating non-thermal plasma at the skin interface electrode; and an isolating element to isolate a region surrounding said skin interface electrode other than during treatment so that non-thermal plasma generated at the skin interface electrode within said region sterilises the skin interface electrode.

Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.
