This novel sensor works according to an optical electrochemical principle and comprises a photoluminescent or fluorescent layer, a light source and a detector. The layer comprises an electric potential and acts as a working electrode which is implemented as a nanostructure (nanowires with quantum dots). Furthermore, spatial resolution can be achieved by using numerous nanowires contacted individually on a carrier and a visual array detector (analogous to CCD sensors in digital cameras).

Currently, continuous fibers in the form of woven or braided structures are used as reinforcement of oxide fiber composites. For the first time, short-fiber reinforced oxide fiber composites with a bending strength of more than 100 MPa can be fabricated. A short-fiber preform made of stapled fiber bundles fulfills the demand of a high fiber volume content, which is required to adjust good mechanical characteristics.

The invention describes a process which enables the separation of permanent magnets out of a crap mixture. In order to achieve this thermal treatment is realized which leads to a partly demagnetization. This enables the following separation in an alternating magnetic field. This process leads to a separate fraction of corresponding permanent magnets. A German as well as an international patent application are pending.

An experimental plant is build up. A proof-of-concept is realized. On behalf of the Westphalian University of Applied Sciences PROvendis offers licenses to interested companies.

This invention concerns a device for internal high-pressure forming of micro-components from tubular moulding blanks. In this novel design, a carriage is sliding along guides, moved by a drive mounted separately from the guides. Hereby, the drive is coupled to the carriage free of any transverse forces. This minimises elastic deformations. Bending stresses in the plungers are avoided. The relative position between guide and forming tool is maintained.

The functional capability of the invention has been proven in many tests. Patents are granted in USA, Germany, France, Great Britain and Suisse. PROvendis is offering licences of the invention to interested parties on behalf of Cologne University of Applied Sciences.

This invention presents a process and an apparatus for the production of water-insoluble lignin granulates for material and energetic usage.
Pulp extraction for manufacturing paper from wood or grasses generates lignin, which has a high calorific value, in large amounts as a side-product and component of waste liquor.

The further use of lignin is prevented especially because of heterogeneity, aroma, water solubility, dust formation, and high reactivity.

This invention proposes a method to make plants more resistant to (repeated) heat stress. This is done by means of using microRNA156 (miRNA156) to increase heat stress tolerance. miRNA156 is expressed under the control of a special heat-inducible promoter to minimize negative side effects such as enhanced leaf induction and later flowering. The proposed invention expresses miRNA156 exclusively by means of heat. The heat-inducible promoter HSP21 ensures that the expression of miR156 is “switched on” by
the application of heat.
