    摘要: A microfluidic device having durable anisotropic wetting fluid contact surfaces in the fluid flow channels of the device. The anisotropic wetting surface generally includes a substrate portion with a multiplicity of projecting regularly shaped microscale or nanoscale asperities disposed in a regular array on the surface. Each asperity has a first asperity rise angle and a second asperity rise angle relative to the substrate. The asperities are structured to meet a desired retentive force ratio (f1/f2) caused by asymmetry between the first asperity rise angle and the second asperity rise angle according to the formula: f1/f2=(ω1+1/2Δθ0)/sin(ω2+1/2Δθ0), Δθ0=(θa,0−θr,0).

    摘要: Certain embodiments include an electrostatic-discharge safe tray for receiving and/or storing electronic components, e.g., read/write heads. Such trays may be made from a mixture of at least one high temperature, high strength polymer, at least one metal oxide, and at least one pigment. The use of the metal oxides as conductive materials advantageously allows for light-colored electrostatic-discharge safe materials to be made, so that such materials may be colored with pigments without compromise of material performance specifications.

    摘要: A tray carrier with ultraphobic surfaces for promoting more effective cleaning and drying of the tray carrier. In the invention, entire surfaces or portions of surfaces of a tray carrier are made ultraphobic. The ultraphobic surfaces of the tray carrier cause liquids that may come in contact with the surface, such as may be used in cleaning, to quickly and easily “roll off” without leaving a liquid film or substantial quantity of liquid droplets. As a result, less time and energy is expended in drying the surfaces, and redeposited residue is minimized, thereby improving overall process quality and facilitating economical reuse of the tray carrier. In addition, the ultraphobic surfaces may be resistant to initial deposition of contaminants, where the contaminants may be in liquid or vapor form.

    摘要: Improved processes for forming shaped articles comprise extruding a composite comprising a polymer and at least one additive, and shaping the composite to form an article having a desired shape. Generally, the extruding and shaping steps are performed on a single process line, which allows the shaped articles to be produced in a continuous process. Due to the continuous process design, shaped articles made by the improved process can be produced in large quantities at a low cost per article. In some embodiments, a shaping station can be employed to shape the extruded composite. The shaping station can comprise a laser machining apparatus, a hot stamping apparatus, rollers having a predetermined pattern, or combinations thereof.

    摘要: A fuel cell with components having durable anisotropic wetting surfaces at selected locations where condensation of water may occur. The anisotropic wetting surface generally includes a substrate portion with a multiplicity of projecting microscale or nanoscale asperities disposed on the surface. Each asperity has a first asperity rise angle and a second asperity rise angle relative to the substrate. The asperities are structured to meet a desired retentive force ratio (f1/f2) caused by asymmetry between the first asperity rise angle and the second asperity rise angle according to the formula: f1/f2=sin(ω1+1/2Δθ0)/sin(ω2+1/2Δθ0), Δθ0=(θa,0−θr,0).

      摘要: A fuel cell component with surfaces having improved lyophilicity so that liquid on the component adheres closely to the surface in relatively flat droplets or sheets. The lyophilic surfaces may be formed with a thin layer of inherently lyophilic polymer on the surface of the component. The lyophilic surfaces may be selectively provided on critical areas of the component, such as for example on flow channel wall surfaces of bipolar plates and membrane electrode assemblies, thereby inhibiting liquid blocking of the flow channels during operation of the fuel cell.
