Composite materials are nowadys used in many technical fields. Blades of wind power plants or aircraft parts, for example, are made out of these materials. In order to detect possible cracks or fractures, however, an immense effort is necessary. Conventional methods of material testing such as ultrasound, X-ray or thermography are very time-consuming, if they are possible to employ whatsoever. Other methods such as the use of strain gauges or glass fiber based systems can take measurements permanently, but they can only indirectly detect a fracture in the material. The invention is a novel, continuous measuring method, which is also suitable in particular for large-area applications such as, for example, wind turbine blades. The sensor consists of a braid of wires whose breaking behavior corresponds to that of the fibers in the composite material. The crossing points are connected via diodes. An electronic evaluation unit can switch between electrical paths through specific diodes so that the defective part can be identified in the breaking event.
Via a small display, data glasses present the eye with information or images which are received using a radio link from the frame of the glasses. The big…

Scientists of the Heinrich-Heine-University developed a rugged low-cost gas detector. The concept of detection based on the specific light emission of compounds excited electronically by an electric arc. The detection enables a wide range of measurments starting from pure gases down to gas traces (<1 ppm). Signals are achieved in tenths of seconds. At present, the invention is primarily concerned with monitoring operational states of fuel cells and appearing degradation processes in MEAs by detecting either nitrogen in the hydrogen flow or hydrogen within the cathode flow field. Granted US Patent und EP patent application, DE application for hydrogen detection. On behalf of the Heinrich-Heine-University of Düsseldorf, PROvendis offers interested companies the opportunity to obtain a licence for using the presented technology or for continuing the development of the method.
The production of recombinant proteins is a multi-billion dollar industry. In order to lower production costs, companies are very active in developing methods for increasing protein yield. However, current techniques are cumbersome, time consuming and consequently relatively expensive.
An innovative method, invented by a scientist at RWTH Aachen, is now about to close this gap in biotechnology. Briefly, the retention time of any target RNA can be significantly increased, leading to a substantially enhanced protein production. The astonishingly straightforward method can be applied in a wide variety of industry branches in white, red and green biotechnology.
