Abstract: Disclosed herein are devices and methods for the purification of biologically contaminated water to make potable. In one embodiment, there is disclosed a low-pressure device comprising a housing having at least one inlet for receiving biologically contaminated water, and at least one outlet for removing purified water, wherein the housing contains a filter held in place by a seal sufficient to keep the biologically contaminated water separate from the purified water. Because of the novel permeability and purification properties of the disclosed carbon containing filter, the disclosed filter can remove virus, bacteria, cyst or any combination thereof, at water approaching velocity up to 5 cm/min. In various embodiments, the filter can have a flat planar design to be used in a flat pack application, or a more traditional tubular shape.

Abstract: Disclosed herein is an electrode comprising, a capacitive carbon material located on at least one surface of a thin. The capacitive carbon material typically comprises functionalized ultra-long carbon nanotubes and optionally another carbon allotrope or mixture of carbon allotropes with sufficiently high active surface area. . Methods of forming such electrodes are also disclosed.

Abstract: There is disclosed an article and method of making an article for removing at least one contaminant from a solid surface. In one embodiment, the article comprises carbon nanotubes attached to a support media, such as a nonwoven mixture of PET and cotton. There is also disclosed a method of removing at least one contaminant from a solid surface, such as areas where microbial, particle, or static contamination is undesirable, including hospitals, clean rooms, kitchens, baths, or human hands.
