A water sterilization device includes: (1) a conduit; (2) a first porous electrode housed in the conduit; (3) a second porous electrode housed in the conduit and disposed adjacent to the first porous electrode; and (4) an electrical source coupled to the first porous electrode and the second porous electrode to apply a voltage difference between the first porous electrode and the second porous electrode. The conduit is configured to provide passage of a fluid stream through the first porous electrode and the second porous electrode, and an inactivation efficiency of pathogens in the fluid stream is at least about 99%, such as at least about 99.9% or at least about 99.95%.

Water sterilization devices and uses thereof

A method for forming a nano-textured surface on a substrate is disclosed. An illustrative embodiment of the present invention comprises dispensing of a nanoparticle ink of nanoparticles and solvent onto the surface of a substrate, distributing the ink to form substantially uniform, liquid nascent layer of the ink, and enabling the solvent to evaporate from the nanoparticle ink thereby inducing the nanoparticles to assemble into an texture layer. Methods in accordance with the present invention enable rapid formation of large-area substrates having a nano-textured surface. Embodiments of the present invention are well suited for texturing substrates using high-speed, large scale, roll-to-roll coating equipment, such as that used in office product, film coating, and flexible packaging applications. Further, embodiments of the present invention are well suited for use with rigid or flexible substrates.

Method for forming a nano-textured substrate

A transparent electrochemical energy storage device includes a pair of electrodes and an electrolyte disposed between the electrodes. Each of the electrodes includes a substrate and a set of electrode materials that are arranged across the substrate in a pattern with a feature dimension no greater than 200 &#x3bc;m and occupying an areal fraction in the range of 5% to 70%.
