Abstract: A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.

Abstract: A patterned conductive article includes a substrate having a first groove therein; a conductive seed layer disposed in the first groove; and a unitary conductive body disposed at least partially in the first groove. The conductive seed layer covers at least a majority of a bottom surface of the first groove, and the unitary conductive body covers the conductive seed layer and at least a majority of side surfaces of the first groove. In a plane through the unitary conductive body that is parallel to and separate from the conductive seed layer, the unitary conductive body has a lower first line edge roughness at a first interface with the side surfaces and the conductive seed layer has a higher second line edge roughness at an edge of the conductive seed layer.

Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: Crowd funding for innovation includes distributing a proposal with a description of a project idea, an amount of funds requested, and a time frame for raising the funds. Ownership of the project is transferred to an entity, which receives contributions from contributors and for each of the received contributions converts the contribution to a corresponding amount of virtual coin and adds the contribution to the funds. If the funding goal is complete within the time frame, the entity converts the coins to actual money and releases the money to the requestor. After completion of the project, the entity determines if the project is successful and can commercialize successful projects. For certain successful projects, the entity can also distribute funds to the contributors.

Abstract: Stretched articles, such as oriented polymeric films or fibers, having microstructure features on at least one surface thereof, and processes for making such articles, are disclosed. A method of making fibers comprises forming a polymeric film having a body having a first surface and a second surface and having a longitudinal dimension. The film also comprises a plurality of elongate microstructure features disposed on the first surface of the body in a direction substantially parallel to the longitudinal dimension of the body, wherein the elongate microstructure features are substantially parallel. The method further comprises stretching the polymeric film in a direction substantially parallel to the longitudinal dimension of the body, and fibrillating the stretched polymeric film along the longitudinal dimension of the body to provide one or more fibers, wherein each fiber has at least one microstructure feature thereon.
