摘要： A thermo-reversible dry adhesive, having shape memory polymer characteristics, introduces one or more particles of micro- or nano-particles to at least one layer of the at least one layer of shape memory polymer. These particles may be remotely activated to induct heat sufficient to transform the dry adhesive material from its temporary shape to its permanent shape in the absence of load, which allows the dry adhesive to be reversibly coupled to one or more substrates, wherein the degree of adhesion is greater when the dry adhesive is in the temporary shape than in the permanent shape.

摘要： The hot stretch forming of sheet metal alloys, such as highly deformable aluminum alloy materials, is improved by using a lubricant comprising bismuth between the forming tool and the engaged surface of the sheet metal. A precursor of bismuth, such as bismuth subsalicylate, may be dispersed in a liquid and applied to the sheet metal before the sheet is heated to its forming temperature. Other lubricants such as boron nitride may be combined with the bismuth precursor. The precursor compound is decomposed to bismuth (or bismuth and carbon in the case of bismuth subsalicylate) which lubricates contact between the surface(s) of the sheet and the forming tool during forming and removal of the formed part from the tool.

摘要： An electrode structure for an electrochemical cell is formed by forming a mixture comprising proton-conductive material and carbon particles, applying the mixture to a current collector sheet to form a film, and dispersing a catalyst in the form of metallic polycrystals in a thin layer on the exposed surface of the film. This method produces an electrode having significantly increased catalyst utilization, dramatic reduction of catalyst loading, and which is consequently less expensive to produce than electrodes produced by prior art methods. A combination electrolyte and electrode structure for an electrochemical cell is produced by hot-pressing an electrode of the above-described composition into contact with a proton-conductive polymer electrolyte membrane.
