Patent number: 7935954Abstract: 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.Type: GrantFiled: November 13, 2006Date of Patent: May 3, 2011Assignee: Borealis Technical LimitedInventors: Avto Tavkhelidze, Jonathan Sidney Edelson, Isaiah Watas Cox, Stuart Harbron

Patent number: 7658772Abstract: 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.Type: GrantFiled: October 20, 2005Date of Patent: February 9, 2010Assignee: Borealis Technical LimitedInventors: Avto Tavkhelidze, Stuart Harbron

Patent number: 7220984Abstract: 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.Type: GrantFiled: July 10, 2006Date of Patent: May 22, 2007Assignee: Borealis Technical LimitedInventors: Avto Tavkhelidze, Stuart Harbron

Publication number: 20020051983Abstract: 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.Type: ApplicationFiled: April 23, 2001Publication date: May 2, 2002Inventor: Stuart Harbron
