    • A method of coating a metallic article having an at least part-metallic surface comprising a first metal, with a surface having a pre-determined wettability, the method at least comprising the steps of: (a) coating at least a part of the metallic article with a layer of a second metal to provide a metal-metal bonded surface, said surface being rough either prior to or because of step (a); and (b) contacting the metal-metal bonded surface of step (a) with a material to provide the surface having the pre-determined wettability. The first metal may be one or more of the group comprising: iron, zinc, copper, tin, nickel and aluminum, and alloys thereof including steel, brass, bronze and nitinol for example. Preferably, the second metal is coated onto the first metal using electroless Galvanic deposition. The nature of the coated metallic article is non-limiting, as the ability of the present invention is to provide a tailored surface with a pre-determined wettability thereon, including superhydrophobic and superhydrophilic wettability. This allows the invention to be capable of application to a wide range of metal types used in different fields.
    • 一种涂覆具有包含第一金属的至少部分金属表面的金属制品的方法,具有预定的润湿性的表面,所述方法至少包括以下步骤:(a)将至少一部分金属 具有第二金属层以提供金属 - 金属接合表面的物品,所述表面在步骤(a)之前或由于步骤(a)而粗糙; 和(b)使步骤(a)的金属 - 金属键合的表面与材料接触以提供具有预定润湿性的表面。 第一金属可以是铁,锌,铜,锡,镍和铝中的一种或多种,​​以及其合金,例如钢,黄铜,青铜和镍钛诺。 优选地,使用无电镀电沉积将第二金属涂覆到第一金属上。 涂覆的金属制品的性质是非限制性的,因为本发明的能力是提供其上具有预定润湿性的定制表面,包括超疏水性和超亲水润湿性。 这允许本发明能够应用于在不同领域中使用的各种金属类型。

    • A method of forming a solid matrix for use with surface-enhanced Raman spectroscopy is described. The method comprises the steps of: admixing a colloidal metal solution with a polymeric support medium to form a suspension; optionally depositing said suspension on a surface; and then drying the suspension to form the matrix. The polymeric support medium provides a plymer/sol suspension in which the sol particles are resistant to aggregation and precipitation. Upon drying the suspension shrinks to provide a mechanically-hard film subsequently usable to provide a sample for spectroscopic analysis.
    • 描述了形成用于表面增强拉曼光谱的固体基质的方法。 该方法包括以下步骤:将胶态金属溶液与聚合物载体介质混合以形成悬浮液; 任选地将所述悬浮液沉积在表面上; 然后干燥悬浮液以形成基质。 聚合物载体介质提供了聚合物/溶胶悬浮液,其中溶胶颗粒耐聚集和沉淀。 干燥后,悬浮液收缩以提供随后可用于提供用于光谱分析的样品的机械硬膜。

    • A discoidal brushless DC motor having a stator (507) carrying windings (503) arranged in slots which radiate out from the center of the stator to the periphery. The depth of each slot increases towards the center of the stator. The slot, therefore, is wider (from side to side) and shallower towards the periphery of the stator, and narrower (from side to side) and deeper towards the center of the stator. This arrangement ensures that the windings are contained below the surface (504) of the stator (507). The magnetic circuit includes a backing of a ferromagnetic material (509). This ferromagnetic material (509) can be a watch spring core made from a long strip of soft iron tape.
    • 一种盘状无刷DC电动机,其具有承载绕着(503)的定子(507),所述绕组(503)布置在从所述定子的中心辐射到所述周边的槽中。 每个槽的深度朝向定子的中心增加。 因此,狭槽(从一侧到另一侧)更宽并且朝向定子的周边浅,并且更窄(从一侧到另一侧)并且更靠近定子的中心。 这种布置确保绕组被包含在定子(507)的表面(504)下方。 磁路包括铁磁材料(509)的背衬。 该铁磁材料(509)可以是由长条软铁带制成的手表弹簧芯。
