    摘要： Various kinds of nanostructured particles like nanorice and nanospears (i.e., tapered nanorods) are made using polymer nanospheres and ordered porous templates. For example, cylindrical nanopores of anodized alumina membranes are filled with polymer nanoparticles by a solvent assisted nanoinjection. Then the membranes are heated in an oven above the glass transition temperature of the polymer. The nanoparticles coalesce to form nanorods with a controlled aspect ratio and terminal contour. The terminal contour can be shaped in the form of nanorice, nanospears or tapered nanorods.

    摘要： A sensor comprises: a pump cell comprising an inner pump electrode, an outer pump electrode, a pump cell electrolyte layer interposed between the inner pump electrode and the outer pump electrode and a cell isolation layer disposed on the inner pump electrode on a side opposite the pump cell electrolyte, wherein the outer electrode is in fluid communication with a reducing gas. A reference cell is in operable communication with the pump cell, the reference cell comprising an outer reference electrode and an inner reference electrode, and a reference cell electrolyte interposed between the outer reference electrode and the inner reference electrode. A diffusion limiting material flanks both sides of a chamber formed between the cell isolation layer and a cell separation layer, wherein the cell separation layer comprises a via coaxial and in fluid communication with the inner pump electrode, the diffusing limiting material, and the outer reference electrode, and wherein the diffusion limiting material has a gas permeability such that the limiting current of oxygen in air is about 0.05 mA to about 5 mA per cm2 of pump electrode area.
