摘要:
The present invention refers to an electrode comprised of a first layer which comprises a mesoporous nanostructured hydrophobic material; and a second layer which comprises a mesoporous nanostructured hydrophilic material arranged on the first layer. In a further aspect, the present invention refers to an electrode comprised of a single layer which comprises a mixture of a mesoporous nanostructured hydrophobic material and a mesoporous nanostructured hydrophilic material; or a single layer comprised of a porous nanostructured material wherein the porous nanostructured material comprises metallic nanostructures which are bound to the surface of the porous nanostructured material. The present invention further refers to the manufacture of these electrodes and their use in metal-air batteries, supercapacitors and fuel cells.
摘要:
A stent formed of polymeric material, useful for the expansion of a lumen and the delivery of one or more therapeutic agents in situ is disclosed. The stent may be multi-layered, and may change shape at a state transition temperature governed by the materials forming the layers. Methods of use and manufacture are also disclosed.
摘要:
A fluid pump for pumping fluid. The fluid pump includes a driver having a substantially tubular shaped body defining a body axis and, a number of elements circumferentially spaced around the body. Each element is responsive to a signal to so as cause a corresponding portion of the body to expand or contract in a direction substantially parallel to the tube axis. The pump also includes an urging member positioned in a flow path. In use, the urging member is coupled to the driver such that selective expansion and/or contraction of the body causes the urging member to rotate, thereby urging fluid along the flow path.
