Abstract: A method and a device for charging electric energy stores are described. At least two electric energy stores to be charged are connected to in each case one charger. The electric energy stores are charged with in each case one charging power assigned to the respective charger. The charging powers are subjected to closed-loop control, wherein the instantaneous charging powers of each charger are determined and added to give an instantaneous total charging power. After a comparison of the instantaneous total charging power with a predefined upper charging power limit, at least one of the charging powers assigned to the respective chargers is reduced if the instantaneous total charging power is greater than the upper charging power limit.

Abstract: Process for the phase transformation of substances and mixtures of substances, in which the substance or the mixture of substances is introduced into a plasma reactor, the substance or the mixture of substances is converted into the higher-energy phase and the product is removed in gaseous form from the plasma reactor. The process can be used for the sublimation of metal salts, metal nitrates and/or metal alkoxides and other vaporizable metal-organic compounds.

Abstract: Method and arrangement for making electrical contact with a membrane-enveloped object using an electrode The invention relates, inter alia, to a method for making electrical contact with a membrane-enveloped object (30) using an electrode (10, 100). According to the invention, it is provided that at least one electrode (100) comprising a conductive carrier (110) is used for making contact, on which carrier a multiplicity of nanoneedles (120) are arranged and on which carrier adjacent nanoneedles are at a distance from one another which is smaller than the size of the object, and that the object is brought into contact with the nanoneedles.

Abstract: The invention relates to a method and a device for producing elementary oxygen or for increasing the concentration thereof in the inhaled air of a user. According to the invention, water is split into hydrogen and elementary oxygen by means of electrical energy (electrolysis), the elementary oxygen is mixed with the inhaled air, and the hydrogen is mixed with the surrounding air in order to be converted back into water (fuel reaction). The splitting of the water into hydrogen and elementary oxygen and the conversion of the hydrogen and surrounding air into water take place simultaneously and continuously, forming a reaction circuit, and are coupled to each other, the electrical energy produced during the conversion being used to reduce the energy demand for the splitting.

Abstract: Process for preparing pulverulent solids, in which one or more oxidizable and/or hydrolysable metal compounds are reacted in a high-temperature zone in the presence of oxygen and/or steam, the reaction mixture is cooled after the reaction, and the pulverulent solid is removed from gaseous substances, wherein at least one metal compound is introduced into the high-temperature zone in solid form and the evaporation temperature of the metal compound is below the temperature of the high-temperature zone.

Abstract: An electrode configuration for field cages, especially in microsystems, comprises a large number of electrodes in which an electrical potential can be applied to each end region through a feed region. The end region is arranged to form the field cage and inhomogeneous shielding fields outside the field cage. To reduce thermal convection, the feed region has a strip form whose width is substantially smaller than characteristic dimensions of the end region.

Abstract: The invention relates to the production of thin metal layers and structures thereof on substrates of various structures. The lateral extent of a metal layer on the respective substrate can be prescribed with a precision in the micron and submicron range. The method described makes it possible to manufacture flat and three-dimensional metal structures on smooth planar or curved surfaces, as are required, for example, for depicting writing or drawings. The method uses no printing techniques.

Abstract: In the method proposed, microparticles suspended in a liquid or droplets suspended in a liquid with which they are immiscible are shaped by high-frequency electric fields in a three-dimensional electrode array of a size in the micrometer or submicrometer range and subsequently consolidated by prior art chemical bonding procedures or by physical methods. The disposition, geometry and control of the electrodes determine the shape of the particles. The particles themselves must have a conductivity and/or relative dielectric constant lower than the solution surrounding them. For some, this can be achieved only at certain frequencies in the kHz and MHz band which are determined by the passive electrical properties of the particles and the surrounding solution. The particles or droplets are repelled by the electrodes so that they are shaped in the free solution without making contact with any surface and can then be consolidated.
