摘要： A method of transferring a chemical activating agent from an applicator to a substrate surface involves providing an applicator having a raised application surface, applying a chemical activating agent to the application surface, contacting the substrate surface with the application surface, and removing the applicator. The chemical activating agent is transferred in a form in which it is capable of effecting a chemical reaction, such as catalysis, at the surface. Thus, following transfer of the chemical activating agent to the surface in a pattern, a metal can be plated at the substrate surface in the pattern. The applicator can be an elastomeric stamp having a raised portion defining a stamping surface.

摘要： The object of the invention is a method for the electrochemical preparation of metal colloids with particle sizes of less than 30 nm, characterized in that one or more salts of one or more metals of groups Ib, IIb, III, IV, V, VI, VIIb, VIII, lanthanoides, and/or actinoides of the periodic table are cathodically reduced in the presence of a stabilizer, optionally with a supporting electrolyte being added, in organic solvents or in solvent mixtures of organic solvents and/or water within a temperature range of between -78.degree. C. and +120.degree. C. to form metal colloidal solutions or redispersible metal colloid powders, optionally in the presence of inert substrates and/or soluble metal salts of the respective metals. The invention further relates to soluble or redispersible colloids as well as application on substrates and immobilization thereof, in particular for the preparation of catalysts.
