Die neue zweiachsige Positioniereinrichtung mit aktiver Impulsentkoppelung ermöglicht schwingungsunterstütztes Bearbeiten von sprödharten Werkstoffen wie Keramik, Glas, Siliziumwerkstoffen oder gehärterem Stahl mit bestehenden Bearbeitungszentren.

The new bridge construction method consists in building the bridge girders in a vertical position and in rotating the bridge girders into the final horizontal position. The span of the bridge girders is reduced by the compression struts, which enables considerable savings in construction materials.

Thermoelectric effects are a fundamental building block for the conception and development of new processes for information processing. They enable to re-use…

Inventors of Saarland University created a new catalytic procedure for the chlorination of alcohols with a variety of advantages, like an excellent waste balance. Substances produced by the new method are for example Neryl chloride, 3-Methyl-3-butenyl chloride, Geranyl chloride and Prenyl chloride.

Scientists of Saarland University and Julius Maximilian University of Würzburg have developed novel water soluble 6-thioalkyl-cyclodextrins, which form highly stable complexes with APIs. The new cyclodextrins show low ion strength in solution and no pH dependence. They can be obtained in well-defined stoichiometry, no statistic, randomly substituted products are generated, thereby simplifying quality control and analysis. Even highly volatile substances such as the anesthetics halothane or sevoflurane can be complexed. For example, one of the new 6-thioalkyl-cyclodextrins showed the highest binding affinities sevoflurane and halothane, much higher than native cyclodextrins or and known cyclodextrin derivatives.

They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed,…
