Abstract:
A superhydrophobic surface is formed by growing a plurality of etchable, sacrificial structures, and depositing a discontinuous hydrophobic material onto the sacrificial structures. The discontinuity facilitates etching of the sacrificial structures to remove the grown structures while leaving the deposited material intact to result in surface features for achieving superior hydrophobic properties.
Abstract:
Verfahren zum Maskieren von Befestigungsbohrungen (14) von Felgen(12), die auf einer Transporteinrichtung(18)einer Felgenbeschichtungsanlage bewegt werden, wobei das Verfahren den Schritt des Ermittelns von Lage und Anzahl nicht maskierter Befestigungs- bohrungen (14) umfasst. Erfindungsgemäß ist vorgesehen, dass eineerstenicht maskierte Befestigungsbohrung (14) einer Felge(12)angefahren wird und dass die erstenicht mas- kierte Befestigungsbohrung (14) mit einem ersten Maskierungselement (36) mittels einer Handhabungseinrichtung(32) maskiert wird. Erst im nachfolgenden Schritt wird eine zweite nicht maskierte Befestigungsbohrung (14) der gleichen Felge (12) angefahren und die zweite nicht maskierte Befestigungsbohrung (14) mit einem zweiten Maskierungsele- ment (36) mittels der Handhabungseinrichtung(32) maskiert.
Abstract:
A scrubbing article 10 including a substrate 12 and a texture layer 14. The texture layer 14 is formed on to a surface 16 of the substrate 12 and includes a multiplicity of microparticles. In some embodiments, the multiplicity of microparticles comprises plastic microbubbles and/or ceramic microspheres that are substantially spherical. In related embodiments, at least some of the ceramic microspheres are solid, and in other embodiments at least some of the ceramic microspheres are glass microbubbles. The substrate 12 can assume various forms, such as nonwoven, fabric (e.g., woven or knitted), foam, film and sponge material or combinations thereof.
Abstract:
A construct that supports cell attachment and alignment including a) a substrate that is incompatible with photolithography conditions; b) a patterned coating of a metal alkoxide, oxide or mixed oxide-alkoxide thereon; and c) a phosphonic acid covalently attached to b), which phosphonic acid contains functionality adapted for cell binding. Also disclosed are methods for preparing such a construct.
Abstract:
Processes for masking electronic devices, including, but not limited to, electronic subassemblies, prior to the application of protective coatings to the electronic devices are disclosed. Such processes include the use of a plurality of different masking techniques in combination to mask the electronic device. Different masking techniques may be used to mask different features and/or components of the electronic device. Some features and/or components may be masked by way of two or more masking techniques. With one or more masks in place, an electronic device may be protectively coated. After a protective coating has been applied to the electronic device, at least a portion of the mask(s) may be removed from the electronic device. Protectively coated electronic devices may then be assembled with one another.
Abstract:
Automated painting of a shoe sole portion is enhanced by use of a mask cover (420) and an air knife (422) with a paint assembly (410). The mask cover is positioned in front of a paint-emitting portion (416) of a spray nozzle (414) and is adapted to obstruct at least a portion of the paint intended to be emitted by the spray nozzle. The air knife is coupled to the mask cover and is adapted to emit a laminar fluid flow over the mask cover. The laminar fluid flow helps to limit unwanted diffusion of the paint as it passes along its intended spray path.
