Abstract: A process for subsequent surface modification of finely structured structures formed from hard inorganic materials, and the structures obtainable by this process as such. The structure has, in at least one spatial direction, a material thickness M of not more than 1000 nm and as an overall structure having, in at least one spatial direction, a measurement which is at least 5 times the material thickness M. The process includes treating the structures with an organic liquid under supercritical conditions.

Abstract: An actuator control arrangement is provided comprising a pair of rotary control valves used in combination to control the operation of an actuator. The rotary control valves are driven synchronously through a hydraulic or mechanical coupling. Each rotary control valve has a by-pass mode which activates in the event of a jam. In addition each rotary control valve has a mechanism for activating the by-pass mode absent any jam. The actuator control arrangement further comprises a circuit coupling a pilot control and/or a flight control computer (FCC) to one or both of the mechanisms for remotely switching the rotary control valve(s) from an active mode to a by-pass mode under control of a pilot or FCC.

Abstract: The present invention relates to a process for producing a porous solid oxidic material from a hydrogel of the oxidic material and to the porous solid oxidic material as such.

Abstract: The present invention relates to a process for producing porous or finely divided solid inorganic materials, the surface of which has been modified with at least one organic substance, under supercritical conditions, wherein the supercritical conditions are lowered by addition of an inert organic substance.

Abstract: A structural element with a controllable heat transfer coefficient comprises a frame. A first sheet and a second sheet opposite one another are arranged in the frame. The sheets and the frame have the effect of defining a closed-off volume which is filled with at least one gas. At least one two-dimensional element is arranged between the sheets. An upper intermediate space is formed between the two-dimensional element and the frame vertically upwardly and a lower intermediate space is formed between the two-dimensional element in the frame vertically downwardly. A first cavity is between the first sheet and the two-dimensional element. A second cavity is between the two-dimensional element and the second sheet. The cavities are connected via the upper intermediate space and the lower intermediate space such that a convection flows between the cavities via the intermediate spaces. At least one means arranged in the intermediate spaces controls the convection flow.

Abstract: The disclosure describes a composition comprising a lipidaceous carrier and a peptide complex formed from poly-L-lysine or a salt thereof; and either poly-L-glutamic acid or poly-L-aspartic acid, or a salt thereof. The composition can be used to prevent or treat a disease related to pulmonary surfactant dysfunction, such as hyaline membrane disease (HMD), respiratory distress syndrome (RDS), hydrocarbon poisoning, near-drowning, HIV/AIDS-related lung diseases, adult respiratory distress syndrome (ARDS), asthma, tuberculosis (TB) or severe acute respiratory syndrome (SARS). Alternatively, the composition can be used to increase the permeability of a pharmaceutical compound or composition across a membrane of a subject. The poly-L-lysine or salt thereof is longer than the poly-L-glutamic acid or poly-L-aspartic acid so that the complex that forms has a charge-neutralised region and a positively-charged region.

Abstract: A method for the production of bipolar plates or electrode plates for fuel cells or electrolyzer stacks is provided, whereby the bipolar plates or electrode plates have at least one punched band and/or at least one punched blank that are punched from a flat material made of a conductive and corrosion-resistant metal and surrounded with plastic, by means of injection molding. A method for the production of a stack of bipolar plates or electrode plates is also provided. The bipolar plate or electrode plate has strips of a punched band material made of a conductive and corrosion-resistant metal.
