摘要： An actuator assembly for use in an electronic device is provided. The actuator assembly includes a support tray formed of a conductive metal and defining an aperture extending through the support tray. A seat surrounds the aperture and supports an actuator. The actuator includes a piezoelectric element adhered to a metal substrate larger than the piezoelectric element. The metal substrate bends when the piezoelectric element contracts and expands in response to changes in the charge of the piezoelectric element. An insulator is disposed between the metal substrate and the support tray which electrically insulates the substrate from the metal substrate.

摘要： A method for preparing a platinum alloy electrode catalyst for DMFC using anhydrous metal chlorides. The method includes reducing platinum chloride and non-aqueous second metal chloride with boron lithium hydride (LiBH4) in a water-incompatible organic solvent in a nitrogen atmosphere to form nano-sized particles of colloidal platinum alloy, and drying the platinum alloy particles without any heat treatment. The method of preparing a platinum alloy catalyst according to the present invention makes it possible to prepare platinum alloy particles having a narrow range of size distribution and an average particle size of less than 2 nm with ease, relative to the conventional methods. The platinum alloy particles thus obtained can be used as an electrode catalyst for DMFC to enhance methanol oxidation performance.
