A replica master mold 10 comprises: a base material layer 11; and a surface shape body 12 formed on the base material layer 11 and having a fine irregular pattern, wherein a softening temperature of the surface shape body 12 is higher than a softening temperature of the base material layer 11.

The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves autoclaving, in a sealed lens package, a silicone hydrogel contact lens having a base coating of polyacrylic acid thereon in an aqueous solution in the presence of a water-soluble, crosslinkable hydrophilic polymeric material having epoxide groups, for a period of time sufficient to covalently attach the crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one epoxide group and one of the carboxyl groups on and/or near the surface of the silicone hydrogel contact lens.

Simultaneous laser welding equipment of a vehicle light including at least a plurality of laser sources suitable for emitting light beams, a plurality of optical fibres associated, at the input ends to the at least one laser source and transmitting the light beams. A light guide is provided with at least one hollow seat that delimits a continuous perimetral contour, counter-shaped to the weld interface. The light guide comprises diffusion elements that pass through the perimetral contour of the seat of the light guide internally, so as to intercept and influence the light beams that propagate inside the seat and that are shaped to expand the light beams along a direction substantially tangent to the curvilinear abscissa defining the perimetral contour, before it projects from the light output wall and/or at the latter.

A surfacing material includes a substrate having a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an electron beam radiation curable material applied to the bottom side of the substrate. The coating is an epoxy acrylic or urethane acrylic laid upon the substrate. The epoxy acrylic or urethane acrylic is irradiated with UV-radiation to produce a UV-radiation layer wherein the epoxy acrylic or urethane acrylic is neither hardened nor is an entire layer of the epoxy acrylic or urethane acrylic crosslinked but rather the epoxy acrylic or urethane acrylic is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A reversible bonded microfluidic structure comprises an overhanging cap or gasket structure atop a continuous microfluidic channel wall. An overhanging gasket structure may reduce stress concentrations at the edge of the channel wall and can permit improved reversible adhesion of the channel wall and adjacent dry adhesive fibers. In one example, reversible adhesion of the overhanging channel wall gasket and adjacent dry adhesive fibers may approach 1 MPa in axial loading. An overhanging gasket structure of the microfluidic channel wall may comprise a single fiber that is continuous around the perimeter of the desired microfluidic channel shape, and may define a self-sealing gasket which will contain fluid. The overhanging gasket structure may be surrounded by further overhanging or undercut dry adhesive fibers to enhance the adhesion and help make the rest of the surface more tolerant to defects and surface roughness.

The present invention provides silk photonic crystals that can be used to enhance light-induced effects. Also disclosed are biocompatible, functionalized, all-protein inverse opals and related methods.
