Abstract: A device (10) for capacitive deionization of an aqueous media containing dissolved ion species, said device comprising a cell with a first primary electrode (2) and a second primary electrode (3) arranged opposite the first primary electrode (2) and preferably separated by at least one non-conductive spacer (4, 4?). A third electrode (7) is arranged between the first and the second electrode. The third electrode (7) is grounded whereas the first and the second electrodes are polarized versus the grounded third electrode.

Abstract: The three-electrode structure for capacitive deionization desalination is a system for desalination of a fluid containing charged species and a process thereof. A capacitive deionization cell has at least three electrodes, wherein the first electrode is connected to either the positive or the negative potential, a second electrode, which is connected to a potential equal in magnitude but having a polarity opposite to that of the first electrode, and a third central electrode, which is placed between the first and second electrodes and is connected to a reference potential.

Abstract: A nanostructured zinc oxide membrane for removing oil from water includes a membrane and a plurality of zinc oxide nanorods on at least one surface of the membrane. The nanorods can cover less than about 40% of the surface of the membrane. Air pockets can be formed in spaces between adjacent nanorods. The nanostructured zinc oxide membranes can be used to separate oil from an oil-water mixture in a cost-effective and energy efficient manner.

Abstract: An apparatus for manufacturing ear devices that are individualized for individual. Data of the three-dimensional shape of each individual's area of application for a haring device is provided. Individual shells for the hearing devices are construed by respectively depositing commonly a layer of one of a liquid and a powderous material and solidifying by a laser arrangement in the layer individually shaped layers of the individual shells, thereby controlling the laser arrangement with the data.
