According to one embodiment, a coagulant comprising calcium nitrate and an antimicrobial agent is disclosed. The coagulant may be used in the molding process to releasably bond the substrate material to the mold and to bond to the antimicrobial to the substrate material.

The present invention relates to a release agent and methods of using a release agent. In particular, the present invention relates to a release agent comprising boron nitride and a fumed metal oxide, which may find use, for example, in metal processing applications.

Disclosed herein are techniques for molding a slanted structure. In some embodiments, a mold for nanoimprint lithography includes a support layer, a polymeric layer on the support layer and including a slanted structure, and an oxide layer on surfaces of the slanted structure. In some embodiments, the oxide layer is conformally deposited on the surfaces of the slanted structure by atomic layer deposition. In some embodiments, the mold further includes an anti-sticking layer on the oxide layer.

A method for manufacturing a three-dimensional structure through nano-imprinting, includes: a stamp preparation step in which a stamp formed with a convex-concave portion corresponding to a pattern of functional layers to be formed is prepared; a material formation step in which at least one material for forming the functional layers is formed to a thickness of several to dozens of nanometers on the convex-concave portion; a material stacking step in which the material formed on the convex-concave portion is stacked on a substrate; and a functional layer securing step in which the material is cured by applying pressure, heat and pressure, or light and pressure thereto such that the material can be converted into the functional layers.

A laminate nanomold includes a layer of perfluoropolyether defining a cavity that has a predetermined shape and a support layer coupled with the layer of perfluoropolyether. The laminate can also include a tie-layer coupling the layer of perfluoropolyether with the support layer. The tie-layer can also include a photocurable component and a thermal curable component. The cavity can have a broadest dimension of less than 500 nanometers.

A molding system and method, allowing for the repeated use of the same molding insert for purposes of elaborate objects molding is described. The proposed method allows for multiple moldings of intricate shapes and curvatures improving the mass production of the jewelry moldings. During the process, the raw molding material is squeezed through the narrow opening inside the mold form under pressure. As the molding material enters the mold form, it is coated with a coating fluid. After the curing, the molding material could be easily removed through a narrow cavity opening, promptly reassembling back to the shape of the insert for continuous use in the next steps of the molding procedure.

Provided are extrusion tools such as extrusion dies or portions thereof having a surface with at least one coating thereon, and methods of forming the same are disclosed. The at least one coating is formed from a composition that is a metal aluminum nitride or carbonitride with particular characteristics such that the amount of aluminum varies within the coating between a coating outer surface and an intermediate thickness within the coating. The resulting coatings have tailored physical and performance characteristics that result in improved wear and extrusion performance.
