The devices may allow diffusion to occur between two fluids with improved transport resistance characteristics as compared to conventional filtration devices. The devices may include a compound structure that includes porous a membrane overlying a support structure. The support structure may define cavity and a a plurality of recesses formed in way a that can allow modified convective flow of first a fluid to provide improved diffusive transport between the first fluid and a second fluid through the membrane.
