  • Patent number: 10481154
    Abstract: Molecularly Imprinted Polymers (MIPs) are utilized to detect diseases and minimize false negative/positive scenarios. MIPs are implemented on a nano-electric circuit in a biochip where interactions of MIPs and an Antigen/Antibody (AG/AB) are detected, and disease specific biomarkers diagnosed. Biomarker detection is achieved with interdigitated gold electrodes in a biochip's microchannel. Capacitance changes due to biomarker interaction with AG/AB electrode coating diagnose diseases in a microfluidic environment. Biofluid passes through the microchannel and exposed to the nanocircuit to generate a capacitance difference and diagnose any specific disease in the biofluid sample. Blood capillary flow in a microchannel curved section experience centrifugal forces that separate liquid from solid. Various blood densities and segments experience different centrifugal effects while flowing through the curved section so serum is separated from various solid matter without using external devices.

  • Patent number: 7479209
    Abstract: Production of pure metals through electro-winning and electro-deposition is accomplished by electrolytic deposition of metal over a reusable stainless-steel plate (cathode). Metal is deposited on both faces of the cathode, as well as on its edges, creating problems when removing the deposited metal. Breaking the deposited edges to remove the metal deposited on both faces produces irregular edges, folding and damages to the surface of the cathode, requiring re-processing, increasing costs of the deposited metal, as well as repairs or replacement of the cathodes. This invention includes a structure made of insulating material to which are fixed electrically energizable cathode guidance profiles with a cross-section similar to an omega and which house the edges of the cathodes, holding them in position during the process.

  • Patent number: 7285193
    Abstract: A cathode for use in the refining or winning of metals, typically used in the electro-refining or winning of copper, comprising a substantially flat deposition plate fixedly attached along an upper edge thereof to an elongate hanger bar thereby defining a connection. A protective cladding is attached to the deposition plate and at least partially surrounding the hanger bar such that a cavity is defined in the region of the connection. A corrosion resistant material fills the cavity. In this manner the corrosion resistant material prevents corrosive substances from penetrating the connection. The corrosion resistant material prevents corrosive electrolytic solution and other liquids from corroding the conductive connection between the deposition plate and the hanger bar which would otherwise reduce efficiency of the cathode.

  • Patent number: 7214296
    Abstract: Object of the invention is an anodic structure for mercury cathode cells for the industrial electrolysis of sodium chloride. The new structure is constituted by a grid array comprising a multiplicity of vertically disposed and mutually parallel titanium blades, covered by an electrocatalytic coating specific for the discharge of chlorine. The ratio between the thickness and the height of the blades is comprised between 1:16 and 1:100 and the ratio between the surface of free passage between the blades and the projected surface is comprised between 15:17 and 25:30. The new grid array is perpendicularly fixed to new or existing frames having the function of mechanical support and current conduction to the grid array. Scope of the invention is simultaneously reducing the energetic consumption of the cell and the costs for restoring the exhausted electrocatalytic coating.
