Abstract: A door assembly is disclosed herein that is usable in a cabinetry system having removable cabinet faces. The door assembly includes a door plate coupleable to at least one hinge assembly, the door plate having a first portion and a second portion extending outward from the first portion. The door assembly also includes a door panel having a recess formed in an inward-facing surface thereof, the recess sized to receive the door plate. A plurality of magnets are inset within the inward-facing surface of the door panel adjacent the recess and are magnetically coupled to the door plate. According to various embodiments, the door plate may have a substantially L-shaped or C-shaped configuration.

Abstract: A cabinetry system includes removable drawer panels, door panels, and trim components, which permit the entire outward appearance of the cabinetry system to be changed within a short period of time. The cabinetry system includes a door assembly having at least one hinge assembly, a metal door plate coupled to the at least one hinge assembly, a door panel having a cavity formed in an inward-facing surface thereof, the cavity sized to receive the metal door plate, and a plurality of magnets coupling the door panel to an outward-facing surface of the metal door plate. After being removed from the cabinets, one set of door and drawer panels may be stored in internal storage components provided within the cabinetry system while a second set of door and drawer panels are in use.

Abstract: A process for forming an epitaxial perovskite-phase thin film on a substrate. This thin film can act as a buffer layer between a Ni substrate and a YBa2Cu3O7−x superconductor layer. The process utilizes alkali or alkaline metal acetates dissolved in halogenated organic acid along with titanium isopropoxide to dip or spin-coat the substrate which is then heated to about 700° C. in an inert gas atmosphere to form the epitaxial film on the substrate. The YBCO superconductor can then be deposited on the layer formed by this invention.

Abstract: A process for producing powders of perovskite-type compounds which comprises mixing a metal alkoxide solution with a lead acetate solution to form a homogeneous, clear metal solution, adding an oxalic acid/n-propanol solution to this metal solution to form an easily filterable, free-flowing precursor powder and then calcining this powder. This process provides fine perovskite-phase powders with ferroelectric properties which are particularly useful in a variety of electronic applications.

Abstract: A method for generation of phase-pure doped and undoped Li.sub.x Mn.sub.y O.sub.z precursors. The method of this invention uses organic solutions instead of aqueous solutions or nonsolution ball milling of dry powders to produce phase-pure precursors. These precursors can be used as cathodes for lithium-polymer electrolyte batteries. Dopants may be homogeneously incorporated to alter the characteristics of the powder.

Abstract: This invention provides improved methods for the preparation of precursor powders that are used in the preparation of superconducting ceramic materials that contain thallium. A first solution that contains the hydrogen peroxide and metal cations, other than thallium, that will be part of the ceramic is quickly mixed with a second solution that contains precipitating anions and thallium (I) to form a precipitate which is dried to yield precursor powders. The precursor powders are calcined an sintered to produce superconducting materials that contain thallium.

Abstract: Method and apparatus for preparing highly pure homogeneous precursor powder mixtures for metal oxide superconductive ceramics. The mixes are prepared by instantaneous precipitation from stoichiometric solutions of metal salts such as nitrates at controlled pH's within the 9 to 12 range, by addition of solutions of non-complexing pyrolyzable cations, such as alkyammonium and carbonate ions.
