Sample processing devices that include transmissive layers and control layers to reduce or eliminate cross-talk between process chambers in the processing device are disclosed. The transmissive layers may transmit significant portions of signal light and/or interrogation light while the control layers block significant portions of signal light and/or interrogation light. Methods of manufacturing processing devices that include transmissive layers and control layers are also disclosed. The methods may involve continuous forming processes including co-extrusion of materials to form the transmissive layer and control layer in a processing device, followed by formation of the process chambers in the control layer. Alternatively, the methods may involve extrusion of materials for the control layer, followed by formation of process chambers in the control layer.

Multilayer processing devices and methods

Described is a method of indirect printing on a thermoplastic film having texture, wherein said method comprises: a) providing a heated thermoplastic melt; b) providing a tool having a molding portion that comprises a texture having a surface and a plurality of cavities in said surface, and that comprises a material having a surface energy sufficient to release ink; c) applying ink to said texture; d) substantially drying or curing said ink; e) contacting said thermoplastic melt with said molding portion having ink applied to it; f) forming a texture in said thermoplastic melt, wherein said texture comprises a plurality of protrusions and an area between said protrusions, that is the inverse of the texture of said molding surface; g) transferring said ink from said molding portion to said thermoplastic melt; h) quenching said thermoplastic melt to form a thermoplastic film; and i) removing said thermoplastic film from said molding portion.

Continuous process for indirect printing of polymeric films having texture

Conformable multilayer films having alternating layers of a stiff polymeric material and a flexible polymeric material are described.

Conformable multilayer films

An abrasive article is provided which comprises a backing; and at least one three-dimensional abrasive coating comprising diamond particles dispersed within a binder bonded to a surface of the backing, the binder comprising a cured binder precursor including a urethane acrylate oligomer. The abrasive article is capable of rapid glass stock removal coupled with reducing the surface finish as indicated by reduced Ra values using an RPP test procedure.

Abrasive article for providing a clear surface finish on glass

A method for polishing a glass workpiece is provided that includes contacting the glass workpiece having an initial Ra with an abrasive article comprising a three-dimensional abrasive coating bonded to a backing, applying a liquid at an interface between the glass workpiece and the abrasive article; moving the glass workpiece and the abrasive article relative to one another; and reducing the initial Ra to a final Ra. The abrasive articles are capable of rapid removal of glass stock from a glass test blank and reducing the surface finish using an RPP test procedure.
