    Abstract: Capacitor material for use in forming capacitors, is disclosed. More specifically, the invention is directed to capacitors formed from this material that have one or more discrete electrodes ( 314 ), each electrode ( 314 ) being exposed to at least two thicknesses of dielectric material ( 300 ). These electrodes ( 314 ) are surrounded by wider insulative material ( 312 ) such that the material can be cut, or patterned into capacitors having specific values. A single electrode can form a small value capacitor while still providing a larger conductive area for attaching the capacitor to associated circuitry. The thin dielectric ( 310 ) can be a tunable material so that the capacitance can be varied with voltage. The tunability can be increased by adding thin electrodes that interact with direct current.

    Abstract: A corrosion-resistant coating for a substrate is described. The corrosion- resistant coating comprises a first distinct layer of a first composition disposed over the substrate, wherein the first distinct layer ha s a thickness that is not greater than about 10 microns, and a second distinct layer of a second composition disposed over the first distin ct layer, wherein the second distinct layer has a thickness that is not greater than about 10 microns an d either the first distinct layer or the second distinct layer is corrosion-resistant. Preferably, the thickness of each distinct layer is less than about 1 or 2 microns, more preferably, less than about 0.4 microns. The coating may comprise additional layers. Corrosion-resistant articles, methods of protecting articles, and methods of depositing corrosion-resistant coatings are also described.

    Abstract: A method for treating diverse pulp and paper materials, including such products contained in municipal solid waste and biohazardous wastes, to produce a homogenous cellulosic product comprises the steps of feeding diverse pulp and paper materials into a vessel, introducing steam into the vessel while agitating the materials, purging the gases from the vessel while agitating the materials, sealing the vessel so that the vessel is pressure tight, saturating the materials with steam at sufficient temperature and pressure to expand the physical and chemical structure of the materials, while agitating the materials, depressurizing the vessel to further enhance the physical and chemical expansion of the materials, and discharging the processed products. Alternatively, the method can be performed without purging the gases, if the temperature in the range of about 140{C to about 160{C, and the pressure is in the range of about 275 to 450 kPa. During the optional purging step, during the depressurization step, and during the optional evacuation step, volatile organic compounds and other air pollutants can be captured and treated. The temperature, pressure, and process time is more than sufficient to decontaminate and sterilize biohazardous laboratory and medical wastes.
