Abstract: Techniques described herein are generally related to metamaterial structures for Q-switching in laser systems. The various described techniques may be applied to methods, systems, devices or combinations thereof. Some described metamaterial structures may include a substrate and a first conductive layer disposed on a first surface of the substrate. A dielectric layer may be disposed on a first surface of the first conductive layer and a second conductive layer having a substantially symmetric geometric shape may be disposed on a first surface of the dielectric layer. The second conductive layer may cover a portion of the first surface of the dielectric layer.

Abstract: Nanobrushes, methods of forming nanobrushes, and methods of altering material with a nanobrush are disclosed herein. A nanobrush may include a substrate having a surface and a plurality of bristles deposited on at least one portion of the surface. The plurality of bristles may be arranged into a plurality of bunches. Each of the plurality of bunches may be spaced from an adjacent bunch at a bunch interval equal to or less than about 100 ?m.

Abstract: A microfluidic device is provided. The microfluidic device includes a microtube having a hollow core. The microfluidic device further includes a plurality of nanopores extending radially outwards from an inner surface of the microtube.

Abstract: A method of forming a shadow mask is provided. The method includes annealing at least one polymeric sheet to form at least one annealed polymeric sheet. The method also includes transferring a pattern from a primary mask to the annealed polymeric sheet using laser micromachining to form the shadow mask.

Abstract: An environmentally benign method for producing binary microfabrication masks is disclosed. An optical target may be provided that includes a water-soluble polymer material in contact with an ultraviolet radiation transmittable substrate. A laser may be focused on a primary mask to produce a mask image, the mask image thereafter being reduced by demagnification optics to provide a reduced image. The optical target may be exposed to the reduced image to create features of reduced size from the primary mask. The water-soluble polymer exposed to the ultraviolet radiation may be ablated from the optical target. The optical target may be subsequently metalized using a metal vapor to coat the remaining polymer material and exposed substrate. The metalized optical target may be contacted with an aqueous fluid to remove the metalized polymer material leaving the binary mask.
