Abstract: A method for exfoliating and/or functionalising lamellar objects is discussed. The steps include immersing at least one portion of a first electrode in a liquid containing the lamellar objects to be exfoliated and/or functionalised, placing a second electrode outside the liquid, at least one portion of the second electrode being opposite a surface of the liquid, generating a plasma between at least one portion of the second electrode facing the surface of the liquid and the surface of the liquid by applying a pulse voltage difference between the first and the second electrode.

Abstract: Method for self-stabilizing deposition of a stoichiometric compound by reactive sputtering using a cold plasma. A reactive gas is supplied to a target, the instantaneous power applied to the target is cyclically reduced and increased at a frequency sufficiently low that a reaction between the target material and the reactive gas takes place on the surface of the target, and the product of the reaction is then sputtered off the surface of the target and onto a substrate. The alternating decrease and increase of the instantaneous power applied to the target at low frequency provides for self-stabilizing deposition of the reaction product on the substrate.
