A plumbing fixture having a multi-color appearance includes a first portion including a first finish having a first appearance and a second portion including a second portion having a second appearance that differs from the first appearance. The plumbing fixture further includes a transition region between the first portion and the second portion, wherein the appearance of the third region is graduated from the first appearance to the second appearance between a first end of the transition region adjacent the first portion and a second end of the transition region adjacent the second portion. The plumbing fixture has an ombré appearance as a result of the graduated transition between the first portion and the second portion.

A method for producing a film includes: coating a surface of a substrate with a composition containing a polymer having a structural unit represented by formula (1) and having a number average molecular weight of 13000 or more and a solvent, heating a coating film formed by the coating, and removing, with a rinsing liquid, a part of the coating film after the heating, wherein the rinsing liquid to be used contains a basic compound. In the formula (1), Y.sup.1 is a single bond, —CO—NR.sup.2—, a divalent aromatic ring group, a divalent group containing —O—, or a divalent group containing —CO—NR.sup.2—. A.sup.1 is a single bond, —O—, —S—, or —NR.sup.3—. R.sup.1 is a hydrogen atom, a monovalent hydrocarbon group, a monovalent halogenated hydrocarbon group, or a monovalent group having a heterocyclic structure. ##STR00001##

A method for manufacturing a bent substrate, having a masking step of forming a masking member (M) on a bent substrate (10) and forming a predetermined pattern, and a printing step of forming a print layer (P) on a surface to be printed of the bent substrate (10) including the masking member (M). It is thereby possible to perform printing on a bent substrate having a curved surface part in a productive manner and at a high printing accuracy.

A method of applying a multi-color finish to a plumbing fixture includes depositing a first coating on the plumbing fixture; selectively applying a masking material in a graduated fashion over at least a portion of the first coating to define a gradient from a first portion of the plumbing fixture that is substantially completely covered by the masking material to a second portion of the plumbing fixture that has substantially no masking material; depositing a second coating over the masking material; and removing the masking material from the plumbing fixture such that the plumbing fixture has a surface finish including a transition region representing a gradual transition between the first coating and the second coating.

A method for structured coating of a surface of a substrate. The surface includes spaced optical elements and at least partially metallic elements provided adjacent the optical elements. After the application of the method, the optical elements should be completely covered with the coating, whereas at least some of the metallic elements should not be coated on the major part of their surface. The method includes: a) providing the substrate with the spaced optical elements and metallic elements; b) applying a sacrificial material to at least some of the metallic elements to form sacrificial spots; c) coating the surface of the substrate with a layer system; and d) detaching the sacrificial spots from the substrate, wherein the regions of the layer system on the sacrificial spots are also detached from the substrate. The application of the sacrificial material is carried out at least partially by jetting.

A method for fabricating a biosensor for metastasis diagnosis. The method includes coating a photoresist layer on a substrate layer, forming a patterned region by patterning the photoresist layer utilizing a photolithography process, forming a nano-roughened patterned region by forming a plurality of nano-features on the patterned region, stripping the photoresist layer from the substrate layer, forming an array of microelectrodes and a corresponding array of electrical connections on the nano-roughened patterned region by depositing a gold/titanium (Au/Ti) bilayer on the substrate layer with the nano-roughened patterned region and forming a metastatic cell sensing trap on at least one microelectrode of the array of microelectrodes. Where, forming the metastatic cell sensing trap includes placing a solution of Human Umbilical Vein Endothelial Cells (HUVECs) on the biosensor and forcing an attachment between at least one HUVEC of the HUVECs and the at least one microelectrode on the biosensor.

The mask assembly includes: a support frame; a mask fixed on the support frame, the mask including an active mask region and an inactive mask region surrounding the active mask region; and a first support bar fixed on the support frame. The first support bar is disposed on a side of the mask facing away from the support frame, a projection of the first support bar onto a plane where the support frame is located is overlapped with a projection of the mask onto the plane where the support frame is located by a first overlapping portion, and the first overlapping portion is located within a projection area of the inactive mask region onto the plane where the support frame is located.

According to certain embodiments, a method of producing a pattern on a substrate comprises securing a flexible polymeric substrate, printing a layer of ink as a negative pattern on the substrate, and placing the flexible polymeric substrate in a vacuum chamber. The method further includes uniformly applying, while the flexible polymeric is under a vacuum in the vacuum chamber, a layer of material over both the layer of ink and the substrate via physical vapor deposition and then removing the flexible polymeric substrate from the vacuum chamber. The method further includes removing the ink and material applied over the ink by immersing the flexible polymeric substrate in a solvent such that it results in a desired pattern of the material on the flexible polymeric substrate.

An all solution-processed deposition includes a non-water soluble, non-self-cracking film deposited by a solution process (e.g., spray, dip, spin coat, and the like), a water soluble, self-cracking film deposited by a solution process (e.g., spray, dip, spin coat, and the like), cracking of the film, and filling the cracks with a metal that is deposited in solution (e.g., by electroless disposition). A transparent substrate having a cracked water insoluble, non-self-cracking film surface coating includes a plurality of fissures therein extending to and exposing portions of the surface of the underlying transparent substrate is useful for producing a transparent conducting film.
