Abstract: The present invention relates to a method, and a cell for carrying out the method for the electrochemical reduction of dinitrogen to ammonia. The method comprises the steps of: (1) contacting a cathodic working electrode comprising a nanostructured catalyst with an electrolyte comprising (a) one or more liquid salts optionally in combination with (b) one or more organic solvents having low viscosity and supporting high ionic conductivity, and (2) introducing dinitrogen and a source of hydrogen to the electrolyte, wherein the dinitrogen is reduced to ammonia at the cathodic working electrode.

Abstract: The invention relates to a method and an electrochemical cell comprising a cathodic working electrode comprising a nanostructured catalyst, a counter electrode and an electrolyte for the reduction of dinitrogen to ammonia. The invention includes introducing dinitrogen and a source of hydrogen to the electrolyte, wherein the dinitrogen is reduced to ammonia at the cathodic working electrode. The electrolyte comprises one or more liquid salts formed from the combination of a specified set of cations and a specified set of anions.

Abstract: The invention relates to a device for the presentation of polypeptides, a method for the preparation and the use thereof, as diagnostic tool (polypeptide chip) for miniaturized and highly parallel detection of structurally or functionally complementary molecules of said polypeptides, i.e. antibodies.
