Abstract: High electrical energy density storage devices are disclosed. The devices include electrochemical capacitors, electrolytic capacitors, hybrid electrochemical-electrolytic capacitors and secondary batteries. Advantageously, the energy storage devices may employ core-shell protonated perovskite submicron or nano particles in composite films that have one or more shell coatings on a protonated perovskite core particle, proton bearing and proton conductive. The shells may be formed of proton barrier materials as well as of electrochemically active materials in various configurations.

Abstract: Light-emitting devices and related methods are described that involve spatially distributing the light emission from a primary light source such as a laser or LED before it is incident on the photoluminescent material. The photoluminescent material emits a secondary emission that may comprise visible light. Some variations of the light-emitting devices may utilize an optical waveguide to couple-in light from the primary light source and spatially distribute the coupled-in light in a controlled manner to pump the photoluminescent material. A variety of configurations for high efficiency light fixtures may be possible using the light-emitting devices and methods described herein.

Abstract: A sacrificial cantilever is used as a template for making cantilevers of non-standard materials for use in an atomic force microscope. The desired metal is deposited onto the sacrificial cantilever, followed by removal of the sacrificial cantilever.

Abstract: A method for forming multiple-component thin films using a separate ion cluster beam (ICB) source for each component. Stoichiometry control is provided by measuring the extraction currents across an acceleration voltage and controlling the component supply to the ICB source. The ion clusters are broken up into an atomic beam by microwave energy. If superconducting films are made, the atomic beams are passed through an oxygen plasma also generated by microwave energy to maximize oxygen incorporation into the thin film. The oxygenated atomic metal ion beams are focused onto a common substrate to form the multiple component thin film. Oxygen is kept away from the ICB sources by differential pumping seals.
