  • Patent number: 7935954
    Abstract: A method is disclosed for the induction of a suitable band gap and electron emissive properties into a substance, in which the substrate is provided with a surface structure corresponding to the interference of electron waves. Lithographic or similar techniques are used, either directly onto a metal mounted on the substrate, or onto a mold which then is used to impress the metal. In a preferred embodiment, a trench or series of nano-sized trenches are formed in the metal.

  • Patent number: 7658772
    Abstract: The present invention is a process for making a matching pair of surfaces, which involves creating a network of channels on one surface of two substrate. The substrates are then coated with one or more layers of materials, the coating extending over the regions between the channels and also partially into the channels. The two coated surfaces are then contacted and pressure is applied, which causes the coatings to be pressed into the network of channels, and surface features on one of the layers of material creates matching surface features in the other, and vice versa. It also results in the formation of a composite. In a final step, the composite is separated, forming a matching pair of surfaces.

  • Patent number: 7220984
    Abstract: The influence of surface geometry on metal properties is studied within the limit of the quantum theory of free electrons. It is shown that a metal surface can be modified with patterned indents to increase the Fermi energy level inside the metal, leading to decrease in electron work function. This effect would exist in any quantum system comprising fermions inside a potential energy box. Also disclosed is a method for making nanostructured surfaces having perpendicular features with sharp edges.

  • Publication number: 20040164799
    Abstract: In general terms, the present invention is an amplifier based on a diode device in which the separation of the electrodes controls the magnitude of the current flowing through the diode. The amplifier of the present invention comprises an emitter electrode separated from a collector electrode by a distance; one or more positioning elements in contact with either or both electrodes to control the magnitude of the distance; a heater element in thermal contact with the emitter electrode; a controller element having an electrical input to be amplified in electrical contact with the positioning elements so as to control the magnitude of the distance; and an amplified output between the collector and the emitter.

  • Publication number: 20020103364
    Abstract: Probes comprise S1 and P1 nuclease (as an enzyme label) linked to a specific binding member such as a nucleotide sequence or an antibody. Such probes are useful for sandwich assays. As compared with known probes using alkaline phosphatase as a label, advantages include relative insensitivity to phosphate and elevated temperature and reduced risk of nonspecific binding.

  • Publication number: 20020051983
    Abstract: The present invention provides a method for detecting nucleic acid amplification product of a target-dependent nucleic acid amplification process involving one or more probes or primers, comprising the steps of: a) treating said product with a nuclease reagent whereby said product is substantially hydrolysed into its mononucleotide components; b) detecting said mononucleotide components. The amplification product is suitably selected for by use of a nuclease reagent that is specific for polyribonucleotide when said product is a polyribonucleotide, and is specific for polydeoxyribonucleotide when said product is a polydeoxyribonucleotide. Alternatively, the detection step may be specific for the mononucleotide components from the product by being selective between ribonucleotides and deoxyribonucleotides.
