    摘要： A silicon-based solid oxide fuel cell (SOFC) with high surface area density in a limited volume is provided. The structure consists of a corrugated nano-thin film electrolyte and a silicon supportive layer on a two-stage silicon wafer through-hole to maximize the electrochemically active surface area within a given volume. The silicon supportive layer is done by boron-etch stop technique with diffusion doping. The fabrication of two-stage wafer through hole combines deep reactive ionic etching (DRIE) and KOH wet etching of silicon for a wafer through hole containing two difference sizes. By these design and fabrication methods, the absolute electrochemically active area can be as high as five times of that of the projected area.

    摘要： A reduced cost solid oxide fuel cell having enhanced surface exchange rates and diffusivity of oxide ions is provided. The invention cell includes a first porous electrode and a second porous electrode, where the porous electrodes have a layer of electronically conductive porous non-precious metal, and the porous non-precious metal layer is a gas diffusion layer. The porous electrodes further include at least one atomic layer of catalytic metal deposited on the non-precious metal layer, and an electrolyte layer disposed between the first porous electrode and the second porous electrode. The electrolyte layer includes a first dense ion-conductive doped oxide film layer, and a second dense ion-conductive doped oxide film layer deposited on the first doped oxide film layer, where the catalytic metal layer on the conductive porous non-metal layer enhances surface exchange rates and diffusivity of the oxide ions, thus the material costs of the fuel cell are reduced.

    摘要： The present invention provides nano-patterning based on flow of an ion current within an ionic conductor to bring ions in proximity to a microscope probe tip touching a surface of the conductor. These ions are then electrochemically reduced to form one or more features on the surface. Ion current flow and the electrochemical reaction are driven by an electrical potential difference between the tip and the ionic conductor. Such features can be erased by reversing the polarity of the potential difference. Indentations can be formed by mechanically removing features formed as described above. The ions in the ion current can be provided by the ionic conductor and/or by oxidation at a counter electrode.

    摘要： An acoustic sensor and method of using same for determining the position of a tool from a workpiece are disclosed in which a piezoelectric transducer having a curved surface emits a sound wave which strikes the workpiece and is reflected back to the sensor. The sensor and tool are positioned relative to one another so that the workpiece will be near the focal point of the curved surface when the tool is operating. This positioning substantially overcomes the attenuation problems of high frequency sound waves transmitted through air.
