    Abstract: A three-dimensional bicontinuous nanoporous platinum-based (3D-BC—NP—Pt(Au)) electrode is prepared by co-electrodepositing Pt and Ag to form a Pt—Ag alloy thin film on a gold substrate, annealing the Pt—Ag alloy thin film deposited on the gold substrate to produce a Pt—Ag—Au alloy, and dealloying the Pt—Ag—Au alloy by dissolving Ag to produce the nanoporous three-dimensional bicontinuous Pt—Au electrode with or without: hierarchical porosity, cylindrical nanopores, and engineered nano-cracks. Electrodes comprising Pt—Au alloys are also provided.

    Abstract: The technology is based on a conducting, ferromagnetic ink made from, in an aqueous suspension: conducting nanopolymers, ferromagnetic nanoparticles, an adhesion promoter and optionally, a surfactant and/or stabilizer. The ink is used to form reversible physical and electrical connections between e.g., rigid and flexible devices. In some aspects, the conducting nanopolymers are PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) nanopolymers and the magnetic nanoparticles are iron oxide nanoparticles. The ink, which may be magnetic, is used to form solid, flexible, ferromagnetic conducting designs or nodes which may also be magnetic. The flexible, ferromagnetic conducting designs or nodes are used to form reversible magnetic electrical connections with devices such as potentiostats and data telemetry devices.
