Abstract: A method for the electrochemical preparation of alkanedicarboxylic acids involves a ring-opening oxidation with a doped Ni(O)OH foam electrode in an aqueous alkaline solution.

Abstract: In one embodiment the semiconductor laser comprises a carrier and an edge-emitting laser diode which is mounted on the carrier and which comprises an active zone for generating a laser radiation and a facet with a radiation exit region. The semiconductor laser further comprises a protective cover, preferably a lens for collimation of the laser radiation. The protective cover is fastened to the facet and to a side surface of the carrier by means of an adhesive. A mean distance between a light entrance side of the protective cover and the facet is at most 60 ?m. The semiconductor laser is configured to be operated in a normal atmosphere without additional gas-tight encapsulation.

Abstract: Systems and methods are provided for optimizing the performance of a mass spectrometer system when multiple measurements are made. For example, the total settling time of different components or stages of a mass spectrometer, such as a tandem mass spectrometer, are decreased by optimally ordering the measurements.

Abstract: The aqueous acid-containing xylose solution is first passed through an ion exchanger to remove the strong acid which was added to the raw material in the xylane hydrolysis and xylose extraction system and then subjected to evaporation in an evaporator. The evaporated water, acetic acid and formic acid of the solution is then condensed and is partly re-cycled and partly subjected to recovery processes. The concentrated xylose solution in the evaporator is then passed through a second ion exchanger to remove any traces of acetic acid or formic acid.
