Abstract: An electrical water filter device includes a plurality of porous electrodes and one or more porous separators. Each of the one or more porous separators is interposed between two adjacent porous electrodes. A respective porous electrode includes a connection portion extending outside an edge of a porous separators next to the respective porous electrode.

Abstract: The method for forming a water sterilization electrode includes heating a conductive medium to an elevated temperature in a heating apparatus. The method further includes growing oxide nanostructures on the conductive medium at the elevated temperature by supplying one or more oxidizing gases to the heating apparatus. The method further includes ramping down from the elevated temperature at 2-30° C./min to a room temperature to form the water sterilization electrode having the oxide nanostructures on the conductive medium.

Abstract: Water disinfection devices and methods are disclosed. In general, one aspect disclosed features an apparatus comprising: a power source configured to supply power to at least two planar electrodes enclosed in a water filtering apparatus, wherein the power source is configured to provide a fixed voltage to the at least two planar electrodes.

Abstract: Water disinfection device configurations and materials are disclosed. In general, one aspect disclosed features an apparatus comprising: a water filtering module including: a rolled stack of sheets, the sheets comprising: an electrode sheet comprising a plurality of porous planar electrodes, a separator sheet comprising a porous planar separator, wherein the porous planar separator is disposed between at least two of the porous planar electrodes, and a perforated pipe extending longitudinally through a center of the rolled stack of sheets; and a case configured to house the rolled stack of sheets, and to direct water through the rolled stack of sheets.

Abstract: A tailoring device. The tailoring device may comprise a tube and a rod, wherein the tube may comprise a channel and one or more slits. The rod may be configured to be inserted through the channel of the tube and secured inside the tube. The slits may be used to partition the tube into one or more smaller tubes. A user may tailor a garment by inserting a measured piece of the garment into the channel of the tube and securing the measured piece of garment inside the tube by inserting the rod through the channel and into the tube while securing the garment inside the tube. The tube and rod may be removed from the garment and may be configured to reusable and easy to use.
