  • Patent number: 9726915
    Abstract: Disclosed is a method to modify the electrical conductivity of an organic and/or molecular material including the steps of providing a reflective or photonic structure and of placing the organic and/or molecular material in or on the structure. The method also includes providing a structure (1) which has an electromagnetic mode which is by design, or can be made by way of adjustment or tuning, resonant with a transition in the organic and/or molecular material (2) and controlling, in particular enhancing, the mobility of the charge carriers, and thus the electrical current, in the organic and/or molecular material (2), by way of strongly coupling the material (2) to the local electromagnetic vacuum field and exploiting the formation of extended macroscopic states in the material.

  • Patent number: 9549878
    Abstract: A set of a first and a second preparation are intended to be mixed before or during an endodontic treatment to form an endodontic irrigation solution. The first preparation includes an oxidizing agent. The second preparation includes antibacterial nanoparticles treated to slow their oxidation by the oxidizing agent. The antibacterial nanoparticles are, for example, encapsulated in shells in a hybrid core-shell structure. In one variation, the antibacterial nanoparticles are made from an alloy of at least two elements, one of the elements being more resistant to oxidation than the other.

  • Patent number: 8354555
    Abstract: This invention provides a method for increasing the activity of catalysts. The method requires the introduction of the catalyst into nano-structured surfaces. The catalysts are introduced as functional groups in molecules forming a monolayer on a surface. A mixed monolayer of catalyst and inert molecules generates ordered domains of molecules on the surface. The catalyst is confined in regions of 0.5 nm to 3 nm in size and is surrounded by an inert material. The presence of such ordered domains that commensurate in size with the reactants, enhance the performance of the catalyst and increase the rate of the reaction.

  • Patent number: 8304273
    Abstract: The present invention provides a method to eliminate undesired parallel conductive paths of nanogap devices for aqueous sensing. The method involves the electrical insulation of an electrode pair, except for the nanogap region wherein electrical response is measured. The magnitude of undesired ionic current in a measurement is reduced by two orders of magnitude. The process to accomplish the present invention is self-aligned and avoids fabrication complexity. The invention has a great potential in nanogap device applications.
