INVESTIGATIONS TO IMPROVE THE TOOL LIFE DURING THERMOMECHANICAL AND INCREMENTAL FORMING OF STEEL AUXILIARY JOINING ELEMENTS

Investigations to improve the tool life during thermomechanical and incremental forming of steel auxiliary joining elements

Modern vehicles as well as structures consist more and more often of a multi material mix.In addition to the use of light materials (e.g.aluminium) to optimise lightweight construction potential, higher strength alloys are being used more and more frequently.With the different material combinations, the requirements for the joining technology also

Comparative Analysis of Bio- and Chemo-Catalysts for the Synthesis of Flavour Compound Hexanal from Linoleic Acid

Hexanal, hexenal, nonenal and their corresponding alcohols are used as green notes in the fragrance and flavour industry.The production of bio-based hexanal starts from linoleic acid, which can be obtained from sunflower or safflower oil.The Toggle Switch biocatalytic process utilizes C13-specific lipoxygenase (LOX) for hydroperoxidation and consec
