    摘要： An internal combustion engine is provided having a cylinder case with at least one cylinder bore wall defining at least one cylinder bore. At least one piston is reciprocally movable within the at least one cylinder bore. The at least one piston includes at least one skirt portion preferably having a barrel-shaped profile. The cylinder bore wall has an oleophobic characteristic, while the at least one skirt portion has an oleophilic characteristic. The oleophobic and oleophilic characteristic is produced by at least one of coating and machining the at least one cylinder bore wall and the at least one skirt portion, respectively.

    摘要： An apparatus is provided having an active material forming a surface thereof in contact with a rheological fluid. The active material is controllable to vary a surface geometry thereof between a rough or nonsmooth surface geometry to increase drag, and achieve an increase in stress transmitted through the fluid, when a field is applied, while allowing a smooth surface geometry and an associated reduction in stress transmitted through the fluid when the field is removed. A method of enhancing performance of an apparatus that includes a rdeological fluid is also provided.

    摘要： A method for embedding a hydrophilic and electrically conductive layer into a flow field plate or bipolar plate for a fuel cell. In one embodiment, the layer is niobium doped titanium oxide in a powder form. The method includes mixing the powder material in a suitable solution, such as a solvent. The solution is deposited on a substrate, such as a stainless steel substrate, by any suitable process, such as brushing. The substrate is then heated so that the solvent evaporates to leave a coating of the powder material. The substrate is then positioned in a die press and is stamped to the shape of the bipolar plate, where the stamping operation embeds the powder material into an outer surface of the bipolar plate.

    摘要： A fixture device generally includes a base member, a reconfigurable pad comprising a shape memory material configured to selectively conform to a surface contour of a workpiece, and a thermoelectric unit in operative communication with the shape memory material of the reconfigurable pad. A process for operating a fixture device includes passing a current in a first direction through a thermoelectric unit in operative communication with a reconfigurable pad in an amount effective to heat a shape memory material therein to or above a shape setting temperature, contacting a surface of a workpiece with the reconfigurable pad, cooling the shape memory material below the shape setting temperature, and fixturing the workpiece with the fixture device.
