    摘要: Improved controlled therapy is provided with a polymer multi-layer structure having a predetermined micro-fabricated spatial pattern (e.g., reservoirs and channels). More specifically, all geometrical details of the spatial pattern are substantially predetermined. The increased control of pattern geometry provided by the invention allows for improved control of therapy. In preferred embodiments, the polymer multi-layer structure of the invention is biodegradable, but has an in vivo lifetime that is greater than the duration of the therapy being provided. Thus, the geometrical pattern of the polymer structure that controls delivery of the therapy persists without significant change during therapy, and the structure degrades after completion of therapy. In this manner, possible interference of degradation by-products with therapy is minimized, and delivery of therapy does not depend on details of how degradation proceeds.

    摘要: A membrane-electrode assembly for a solid oxide fuel cell is provided. The membrane-electrode assembly has a substantially constant-thickness electrolyte layer. The electrolyte layer distinguishes first and second electrolyte layer surfaces arranged in a three-dimensional pattern with opposite first and second planar pattern surfaces. The three-dimensional pattern has a first set of features extending inward from the first planar pattern surface. It has a second set of features extending inward from the second planar pattern surface opposite to the first planar pattern surface. A first electrode layer is adjacent and conforming to the first electrolyte layer surface. At least one mechanical support structure exists within some or all of the second set of features. A second electrode layer is adjacent and conforming to the second electrolyte layer surface and to at least one mechanical support structure. The membrane-electrode assembly is deposited on a substrate with at least one through hole.

    摘要: Provided are various examples of lithium electrode subassemblies, lithium ion cells using such subassemblies, and methods of fabricating such subassemblies. Methods generally include receiving nanostructures containing electrochemically active materials and interconnecting at least a portion of these nanostructures. Interconnecting may involve depositing one or more interconnecting materials, such as amorphous silicon and/or metal containing materials. Interconnecting may additionally or alternatively involve treating a layer containing the nanostructures using various techniques, such as compressing the layer, heating the layer, and/or passing an electrical current through the layer. These methods may be used to interconnect nanostructures containing one or more high capacity materials, such as silicon, germanium, and tin, and having various shapes or forms, such as nanowires, nanoparticles, and nano-flakes.
