    摘要： A method for applying texture to an aerodynamic surface is provided. A master plate is provided having a textured surface. A first material is then applied to that surface and cured forming a caul sheet with a negative impression of the master plate textured surface. A surface to which a texture is to be applied is then provided; this may be an aerodynamic surface. Another material, different from the first, is then applied to the aerodynamic surface and the caul sheet is placed on top. The second material is cured and the caul sheet is removed. The second material is adhered to the aerodynamic surface and has a surface that is substantially a negative impression of the caul sheet textured surface and substantially similar to the master plate textured surface.

    摘要： A phononic material includes an interface surface and a subsurface feature mechanically connected to the interface surface. When a hypersonic flow having at least one instability flows past the interface surface, the interface surface vibrates in response to one or more frequency components of the pressure. The interface surface couples each frequency component into the subsurface feature, which at least partially reflects and phase-shifts each frequency component to generate a corresponding phase-shifted frequency component. The interface surface vibrates in response to the phase-shifted frequency component, thereby coupling the phase-shifted frequency component back into the hypersonic flow. The phase-shifted frequency component interferes with said each frequency component within the hypersonic flow. The subsurface feature may perform phase-shifting such that the phase-shifted frequency component destructively interferes with said each frequency component, thereby reducing the at least one instability.

    摘要： Actuatable microstructures and methods of making the same are disclosed. An example a sheet includes a first side including an elastomeric material and a second side opposite the first side. The sheet defines sealed channels. In response to a pressure differential across the elastomeric material, the elastomeric material is to be in a deformed position relative to the sealed channels to define microstructures.

    摘要： A fluid control film is provided that includes fluid control channels extending along a channel longitudinal axis. Each of the fluid control channels has a surface and is configured to allow capillary movement of liquid in the channels. The fluid control film further includes a hydrophilic surface treatment covalently bonded to at least a portion of the surface of the fluid control channels. The fluid control film exhibits a capillary rise percent recovery of at least ten percent. Typically, the hydrophilic surface treatment includes functional groups selected from a non-zwitterionic sulfonate, a non-zwitterionic carboxylate, a zwitterionic sulfonate, a zwitterionic carboxylate, a zwitterionic phosphate, a zwitterionic phosphonic acid, and/or a zwitterionic phosphonate. A process for forming a fluid control film is also provided. Further, a process for cleaning a structured surface is provided, including providing a structured surface and a hydrophilic surface treatment covalently bonded to at least a portion of the structured surface, and soiling the structured surface with a material. The process also includes removing the material by at least one of submerging the structured surface in an aqueous fluid, rinsing the structured surface with an aqueous fluid, condensing an aqueous fluid on the structure surface, or wiping the structured surface with a cleaning implement.
