Abstract: One example of a flexible printed article includes a non-conductive, graphene oxide membrane base substrate; and an electronic component positioned on the non- conductive, graphene oxide membrane base substrate. An example method for generating this example of the flexible printed article includes inkjet printing a conductive ink directly on the non-conductive graphene oxide membrane base substrate.

Abstract: An example of a kit for three-dimensional (3D) printing includes an ultraviolet (UV) light fusing agent and a detailing agent. The UV light fusing agent including an aqueous vehicle and a plasmonic metal nanoparticle that i) provides absorption enhancement at radiation wavelengths ranging from about 340 nm to about 450 nm, and ii) is present in an amount up to 2 wt% based on a total weight of the UV light fusing agent. The detailing agent includes a surfactant, a co-solvent, and water.
