A bistable nonlinear electromagnetic energy harvester coupled to an impulsively excited primary linear oscillator has been experimentally investigated. The design of the energy harvesting system was guided by a preliminary numerical study, which predicted a favorable dynamic regime for harvesting purposes.
Several studies on membrane reactors for hydrogen production have shown that the permeation of hydrogen may be inhibited by the competitive adsorption of one or more of the reactants. This adsorption-inhibition effect, often accounted for in rate expressions of catalytic reactions, may induce the existence of multiple steady state solutions. In this work we investigate the possible presence of bistability in membrane reactors.
