Abstract: An electrode and a system for electrochemical hydrogen production from water oxidation and proton reduction can include covalently attaching a ruthenium complex onto a conducting material is provided by fluorine-doping a carbon cloth (FCC) and use this as an anode and/or a cathode in an electrochemical cell. The electrode for use in electrochemical hydrogen production from water oxidation is achieved by that the electrode comprises a ruthenium complex covalently attached onto a conducting material having a pyridine linker with a —CH2—CH2 spacer unit. The system for electrochemical hydrogen production from water oxidation and proton reduction can include at least an electrochemical cell having two electrodes, an anode and/or a cathode, where the electrodes comprise a ruthenium complex covalently attached onto a conducting material, is achieved by that the conducting material is made by fluorine-doped carbon cloth (FCC).

Abstract: An electrochemical system comprising at least one half-cell (1, 100) adapted for holding a first electrolyte, a first electrocatalyst (10) arranged on a current collector (11) forming a first working electrode, and a first auxiliary electrode material (12) arranged on a second current collector (13), and optionally a second half-cell (2, 200) adapted for holding a second electrolyte, a second electrocatalyst (20) arranged on a current collector (21) forming a second working electrode, and a second auxiliary electrode material (20) arranged on a current collector (21), wherein the working electrode and the auxiliary electrode are connected to an external circuit including a power supply (300) and a control unit (400), and wherein the polarity of the power supply determines whether the working electrode acts as a cathode or an anode, thus creating a cathodic or an anodic half-cell. A method for electrochemical production of chemicals and gases, in particular hydrogen, using said cell or system of cells.

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.
