An innovative procedure has been developed to control induction heating of material used for semi-solid metal casting. By analyzing electrical value and permeability of the material the grain structure can be determined during the heating process. The induction heating can be regulated accordingly so that the material retains the optimal grain structure for forming.
The invention offers a method for generation of reproducible secret keys in products which were manufactured by means of lithographic production processes, such as chips.
The invention covers a new kind of monolithically integrated optical fibre coupling and its fabrication method.
At the University of Stuttgart (Germany) a new method and device were developed, which demodulates optical signals with 3 bit information per signal. At the same time the technical complexity of the receiver is reduced.
The new receive equalizer topology permits to reduce the equalizer chip area by a factor of 5 to 10 and to cut down power consumption by half compared to common equalizers.
Data rates far in excess of 10 Gbit/s can be achieved with the new structure.
Researchers at the University of Hohenheim are investigating membrane materials which at room temperature and at normal pressure exhibit a high diffusion coefficient for CO2 and at the same time retain methane securely. The selectively permeable materials could be used in e.g. innovative biogas containers to increase the energy content of biogas in a very simple and effective way.
Hydrogen is regarded as the energy source of the future. At Heidelberg University relatively inexpensive hydrogen storage materials have been developed, that allow a rapid and reversible uptake/release of hydrogen under mild conditions. The innovative storage materials can be used as a molecular, oligomeric or polymeric solid as well as in liquid form.
At the fem Research Institute for Precious Metals and Metals Chemistry in Schwaebisch Gmuend, Germany, a novel free-form casting process has been developed for the production of massive metallic glass products. The process is based on a combination of the established processing steps: wax modelling, electroforming, and investment casting. Using this process it is for the first time possible to produce relatively simply, quickly and cost-effectively even filigree and geometrically complex metallic glass products in small to medium production volumes.
Epigenetic modifications at the 5-position of cytosine in DNA provide important clues for diseases such as neurological disorders and a range of cancers. Scientists at the University of Constance have now developed a method which allows the direct detection, i.e. without prior chemical modification of the DNA sample, of the epigenetic modification status in the 5-position of cytosine (such as 5mC and 5hmC) in any user-defined sequence. It is a simple and reliable method with high resolution and can be combined with a multitude of detection methods. Detection both in vivo and in vitro is possible.
At the University of Konstanz a novel method with very high selectivity has been developed, which allows the inclusion of amino acids with nucleic acid-intercalating properties into proteins and peptides. Protein- and peptide-based active pharmaceutical components often contain structures that act as intercalators. The technology uses standard protein expression methods and only requires the presence of the ncAA in the medium and the co-expression of the respective aminoacyl-tRNA synthetases as well as the tRNA. The invention has substantial potential for the development of new applications and products, in particular in the pharmaceutical and biotech fields.
Digital beam forming systems simultaneously improve resolution and dynamic range. Usually the dynamic range of a system suffers, when there is only a limited number of senders and receivers. The present invention offers a process to increase the dynamic range of multi-sender multi-receiver systems which have only a small number of elements in the group. The system provides increased dynamic response even with a small number of antennae. The number of elements in a group of senders and receivers can be reduced, which in turn lowers the hardware costs.
All signal components (both the carrier signals and the frequency-modulated signal components) can be evaluated. Therefore ambiguities can be resolved. Using the frequency-modulated signal components, it is no longer necessary to compromise between the explicit angular range and the resolution.
The novel MEDUSA technology for turbocharging combustion engines fits the current trend to downsize engines perfectly. The optimal inflow into the turbine, particularly at low speeds of revolution, makes the engine very responsive, with maximum torque developing in the lower range of rotatory speed. Additionally the exhaust tract that forms part of the invention is extremely robust, in particular at high combustion temperatures. Thus the technology is particularly suited for use in small gasoline engines: the efficiency is greater than for wastegate turbochargers; however, unlike the Variable Turbine Geometry (VTG) turbocharger, this charger does not require adjustable guide vanes.
To understand biological functions at a molecular level it is important to know how proteins moving around. Todays optical equipment cannot resolve and track single molecules with high resolution in living cells. Our scientists developed a method for long-term detecting single molecules in living cells based on carbon nanotubes.
Surface treatment is a common step in many manufacturing processes but also in medicine (e.g. disinfection or wound healing). Scientists at the University of Applied Sciences and Arts developed a 2in1 plasma device for combined surface preparation with cold-plasma and electromagnetic radiation (e.g. UV or IR).
Researchers of molecular diabetology at the University of Bremen have now identified a key protein, protein kinase MST-1, which is responsible for the death of these insulin-producing cells due to apoptosis (programmed cell death) and thus for the formation of the diabetes disease. This is valid for both forms of diabetes, namely the autoimmune type 1 and type 2, which depends on age and obesity. More than 7 million people are affected by this disease in Germany.
The scientists are carrying out intensive research on the involvement of the protein kinase MST-1 in the apoptopic processes in the beta cells.
In laboratory models, it was possible to demonstrate that the targeted inhibition of MST-1 was able to maintain the secretion of insulin and prevent the disease from progressing. Assays have been developed which can be used by means of in vivo and in vitro tests to show which MST1 inhibitors can prevent diabetes.
A worldwide patent is applied for this new approach. Companies are addressed which may are interested in a license or cooperation with the university of Bremen.
