The present invention relates to textile articles and clothing such as outdoor garments, indoor garments, and commercial protective wear exposed to contact mixtures of water and oil, swimwear and winter wear exposed to mixtures of water and air. At least part of these textile articles possess a surface provided with at least one of 1) a high surface area, 2) hierarchical pattern, 3) contact angles such that hydrophilic portion of a contact mixture possesses a high contact angle and the hydrophobic portion of a contact mixture possesses a low contact angle, and 4) hysteresis angle greater than 5 degrees. Hydrophobic/Hydrophilic contact mixtures of the present invention can be surfaces where water and or ice are present in combination with oil and or air. The textile articles of the present invention resist slippage on surfaces possessing hydrophobic/hydrophilic contact mixtures.

Method and arrangement for assembling one or more microchips (415; 615; 715; 815; 915; 1015) into one or more holes (422; 722), respectively, in a substrate surface (421; 721) of a separate receiving substrate (420; 720; 820; 1020). The holes (422; 722) of the substrate is for microchip insertion out-of-plane in relation to said substrate surface. Each of said microchips is provided with a ferromagnetic layer (213; 613) of ferromagnetic material. The microchips are placed (503) on said substrate surface (421; 721) and it is applied and moved (504) one or more magnetic fields affecting said ferromagnetic layer (213; 613) of each microchip such that the microchips thereby become out-of-plane oriented in relation to said substrate surface (421; 721) and move over the substrate surface (421; 721) until assembled into said holes (422; 722).

A microelectromechanical systems (MEMS) diaphragm assembly comprises a first diaphragm and a second diaphragm. A plurality of pillars connects the first and second diaphragms, wherein the plurality of pillars has a higher distribution density at a geometric center of the MEMS diaphragm assembly than at an outer periphery thereof.

In an example, a wet cleaning process is performed to clean a structure having features and openings between the features while preventing drying of the structure. After performing the wet cleaning process, a polymer solution is deposited in the openings while continuing to prevent any drying of the structure. A sacrificial polymer material is formed in the openings from the polymer solution. The structure may be used in semiconductor devices, such as integrated circuits, memory devices, MEMS, among others.

A microdevice containing a plurality of nanowires on a biocompatible surface, and methods of making and using the same are provided. Aspects of the present disclosure include forming a plurality of microdevices on a substrate where each microdevice includes a plurality of nanowires. The nanowires may be loaded with an active agent by disposing the active agent onto the surface of the nanowires. Also provided herein are kits that include the subject microdevices.

A method to remove selected parts of a thin-film material otherwise uniformly deposited over a template is disclosed. The methods rely on a suitable potting material to encapsulate and snatch the deposited material on apexes of the template. The process may yield one and/or two devices during a single process step: (i) thin-film material(s) with micro- and/or nano-perforations defined by the shape of template apexes, and (ii) micro- and/or nano-particles shaped and positioned in the potting material by the design of the template apexes. The devices made from this method may find applications in fabrication of mechanical, chemical, electrical and optical devices.
