  • Publication number: 20100068374
    Abstract: The invention relates to a method for marking an item based on the formation of colour centres on a lithium fluoride film. The method provides for the deposition of thin LiF films on the item or on mark supports to be applied to the item and the formation of the colour centres by irradiation, thus forming an identification mark. Optionally, the method may provide for the detection of the identification mark and the control of its authenticity. The method may be employed both to guarantee the authenticity of the item and to classify it. The application of the method is particularly advantageous in the field of high value goods and specifically in the field of cultural objects.

  • Publication number: 20100035074
    Abstract: A method of modifying a polymeric, inorganic, or organic-functionalized substrate surface is provided. In one embodiment, an atmospheric pressure (AP) plasma stream is directed at a substrate surface, leading to the formation of surface-bound active sites that function as polymerization initiators. When contacted with a monomer or monomer solution, the active sites facilitate formation of a dense array of graft polymers covalently bound to the substrate surface. In another embodiment, an inorganic substrate is cleaned, conditioned in a humidity chamber, treated with an AP plasma, and contacted with a monomer or monomer solution to facilitate formation and growth of graft polymers on the substrate surface.

  • Publication number: 20090280650
    Abstract: Methods of depositing and curing a dielectric material on a substrate are described. The methods may include the steps of providing a processing chamber partitioned into a first plasma region and a second plasma region, and delivering the substrate to the processing chamber, where the substrate occupies a portion of the second plasma region. The methods may further include forming a first plasma in the first plasma region, where the first plasma does not directly contact with the substrate, and depositing the dielectric material on the substrate to form a dielectric layer. One or more reactants excited by the first plasma are used in the deposition of the dielectric material. The methods may additional include curing the dielectric layer by forming a second plasma in the second plasma region, where one or more carbon-containing species is removed from the dielectric layer.

  • Patent number: 7611752
    Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.
