Abstract: A layered structure includes a silicon-based substrate comprising a substrate surface; a titanium-copper seed layer arranged on the substrate surface, wherein the titanium-copper seed layer comprises a titanium layer and a copper layer, wherein the titanium layer is arranged on the substrate surface such that covalent bonds are formed between the titanium layer and silicon of the silicon-based substrate, and wherein the copper layer is arranged directly on the titanium layer, such that the titanium layer is arranged between the substrate surface and the copper layer; and a nickel-iron plating layer arranged directly on the copper layer of the titanium-copper seed layer such that the titanium-copper seed layer is arranged between the silicon-based substrate and the nickel-iron plating layer.

Abstract: A two-stage process for the preparation of organic isocyanates by reacting primary amines with phosgene in which: a) in a first stage, amine and phosgene are reacted in an adiabatically managed reaction, in which the temperature of reaction is restricted to values between 100 and 220° C. by actively adjusting the absolute pressure in the reactor to values between 8 and 50 bar by decompression, and the temperature is held at values between 100 and 220° C. until the stoichiometric conversion of phosgene has reached at least 80%; and then b) in a second stage, the reaction mixture from a) is decompressed to an absolute pressure of 1 to 15 bar and the reaction mixture is reacted further at temperatures between 90 and 240° C., optionally with the introduction of heat.

Abstract: The invention relates to a process for coating a substrate with a nitrogen-free compound corresponding to formula (I) and/or a hydrolysis product or condensation product [R1(R2)j]iSiR3k(OR4)4−k−i  (I), wherein i represents the number 1, 2 or 3, j represents an integer from 1 to 10, k represents the number 0, 1 or 2, k+i is ≦3, and R1 represents OH, OR, SH, SR, OOC—R, R represents C1-C10-alkyl or C6-C12-aryl, R2 is an unsubstituted, singly substituted, or doubly substituted methylene group, R3 is a substituted or unsubstituted C1-C10-alkyl or C6-C12-aryl group, R4 represents a C1-C10-alkyl or C6-C12-aryl group, and wherein if j represents from 2 to 10 the methylene groups in the chain may optionally be interrupted once or several times by hetero atoms.

Abstract: An X-ray mammography device has an X-ray tube arrangement, a compression mechanism, a subject table, and a large-area solid-state detector made of amorphous silicon (a-Si) which is integrated in a detector cassette that can be inserted into the subject table and that has a first part of at least one transmission path for supplying the operating voltage, and/or the control signals for operating the solid-state detector and/or the readout data, this first said part engaging functionally with a corresponding second part of the transmission path which is attached at the subject table.
