20090195300 | Gate controlled atomic switch - The invention relates to a method for producing a switch element. The invention is characterised in that the switch element comprises three electrodes that are located in an electrolyte, two of which (source electrode and drain electrode) are interconnected by a bridge consisting of one or more atoms that can be reversibly opened and closed. The opening and closing of said contact between the source and drain electrodes can be controlled by the potential that is applied to the third electrode (gate electrode). The switch element is produced by the repeated application of potential cycles between the gate electrode and the source or drain electrode. The potential is increased and reduced during the potential cycles until the conductance between the source and drain electrode can be switched back and forth between two conductances, as a result of said change in potential in the gate electrode, as a reproducible function of the voltage of the gate electrode. | 08-06-2009 |
20100107907 | DIE FOR MICRO CONTACT PRINTING AND METHOD FOR THE PRODUCTION THEREOF - A die for the micro contact printing includes a die body and a die surface that is fixedly connected to the die body. The die surface is divided into at least two different regions. Each of the at least two regions comprises a different material having a different absorption capacity for printing ink. At least one of the at least two regions has a lateral dimension of no more than 1000 nanometers. | 05-06-2010 |
20100273328 | METHOD FOR PRODUCING AN ORGANOMETALLIC LAYER - A method for producing an organometallic layer includes providing a substrate having at least a layer with atoms of an oxidizable metal on its surface. The surface is exposed to a fluid that includes organic molecules having at least two functional groups that contain elements of main group VI such that the atoms of the oxidizable metal form a bond with the organic molecules. By consumption of the atoms of oxidizable metal and of the organic molecules, the organometallic layer is formed on the substrate at locations on the surface of the substrate where the atoms of oxizable are disposed, the atoms of oxizable metal being incorporated into the organometallic layer. A thickness of the organometallic layer is determined by a duration of the exposing, a thickness of the layer including the atoms of the oxidizable metal, and the number of organic molecules in the fluid. | 10-28-2010 |

20120154817 | METHOD FOR DEMONSTRATING THE PRESENCE OF MOLECULES BY MEANS OF OPTICAL GRATINGS - A method for detecting the presence of molecules includes bringing into contact with at least one optical grating comprised of a first liquid phase, a second liquid phase which cannot be mixed with the first liquid phase. The first liquid phase is arranged on a substrate in a form of periodic structures having a periodicity ranging from about 190 nm to about 10 μm. The molecules to be detected, which are capable of changing the optical characteristics of the at least one optical grating are added to the first liquid phase or to the second liquid phase either before, during or after the bringing step. The presence of molecules is detected by measuring a changed reflection or transmission of light at the at least one optical grating or a changing spatial course of the diffraction pattern as soon as the first liquid phase makes contact with the second liquid phase and with the molecules to be detected. | 06-21-2012 |
