Diamondoids are molecules whose framework structure constitutes a section of the diamond lattice. Due to their size in the range of 0.5-2 nm, they can be considered as ?nano-diamonds? with a hydrogen-terminated surface.
Since they are extremely similar to diamonds and therefore possess many of their positive properties, diamondoids have the potential to serve as an enabling technology.
Scientists from Goethe University Frankfurt am Main have developed the so-called STRAP (Steering of Tonotopic Rate Adaptive Pitch) procedure for optimizing the stimulation strategy for cochlea implants. By position-dependent adjustment of the stimulation rate to each individual electrode, a much more precise pitch perception is achieved.
This development enables the simple, wet-chemical, microwave-assisted production of non-agglomerating nanoparticles (e.g. titanium oxide, zinc oxide, zirconium dioxide) from metal salts.
Key advantages of this development include the production of nanoparticles of variable sizes and the prevention of agglomeration.
This invention is a laser-arc hybrid welding process that uses a specially shaped electrode made of filler metal. Unlike conventional laser-arc welding processes, the coaxial arrangement of the individual processes results in a deeper penetration depth with increased process speed and improved inert gas efficacy. In addition, workpieces can be welded regardless of orientation and in forced position welding, because a change of direction does not result in any changes in the arrangement of the arc-electrode-laser beam.
In FRET (Fluorescence Resonance Energy Transfer) experiments, dark quenchers like Dabcyl are widely used to avoid background noise resulting from an overlap between quencher and reporter fluorescence spectra. They provide a predictable way of modulating the fluorescence emission intensity of fluorophores without occupying an emission bandwidth. Although Dabcyl is one of the most frequently used fluorescence quencher, the very poor solubility in aqueous solutions due to its hydrophobic properties limits its use in biological systems where the natural solvent is water. The present invention provides a new dark quencher called Hydrodabcyl, which represents the hydrophilic alternative to Dabcyl.
Localized conducting nanostructure fabrication by bottom-up approaches, such as focused electron or ion beam induced deposition (FEBID/ FIBID) or selective-area atomic layer deposition (SA-ALD), are more and more frequently used in different application fields. Researchers from the Goethe University Frankfurt am Main have developed a semi-automatic electrical conduction optimization process for these bottom-up techniques. The process is fully customizable, highly efficient and fast.
This invention provides a device for the agglomeration of very finely distributed solids, colloids, or fibres, especially in elutriates, pasty goods, fine particle systems, and/or liquids (pelletization equipment) with alternative reactor geometry and a new reactor design that makes it possible to improve the agglomeration of suspended particles (with a size of > 1 µm) and to increase throughput of treatable substances, such as sludge or slurry.
In order to conduct vibration analyses to determine eigenfrequencies, modal damping, and eigenforms, a test specimen must be set into position and subjected to vibrations. The invention is an arrangement and process that simultaneously enables the free-free positioning of test specimens and the excitation of vibrations.
The new recombinant protein is based on the recently identified Cea1 adhesin from the yeast Pichia pastoris. It provides a high specificity for non-reducing N-acetylglucosamine (GlcNAc) ends of non-crystalline chitin, chitin-like polymers, or N-linked glycans, while recognition of glucose, glucosamine, or N-acetylneuraminic acid (Neu5Ac) is subordinate.
The technology therefore enables highly specific binding of chitin or chitin-like polymers in the context of biomedical or biotechnological applications.
The new method enables the determination of birefringence from unknown samples in absolute values without a calibration of the apparatus. Furthermore it allows a quantitative analysis of the materials with regard to robustness, elongation at rupture and colour uniformity. The method can easily be integrated in normal polarisation microscopes and provides the possibility of analysing optical retardation with spatial resolution.
While conventional sensor concepts are often not suitable for micro dimensions and too expensive, the new sensor system MicroDetec is ideal for continuous operating mode and sensitive flow conditions in microreactors. The measurement method exploits the phenomenon, that the fluids in biphasic flow in non-conductive micro channels undergo a polarization. This polarization is monitored by an electrode, which is flush fitted on a non-conductive channel (e.g. PTFE). To improve the signal / noise ratio, the measuring point is electrically shielded and the measuring signal is amplified. Micro process technology offers a lot of potential for the intensification of chemical, biochemical and pharmaceutical production. MicroDetec is protected by an international patent application. A first operating prototype has been built. PROvendis is offering licenses for the invention to interested companies on behalf of the TU Dortmund. There is also the possibility of collaboration with the inventors.
The invention describes a method to detect falls with the help of air pressure sensors. The sensors are attached to the patients body facing different directions in order to detect the dynamic pressure caused by a fall. At the same time those parts of the protection equipment protecting the specific part of the body that is likely to experience an impact based on the dynamic pressure are activated.
Metal oxide layers for semiconductor sensors or solar cells (e.g. tandem solar cells based on Cu2O) are usually produced by sputtering (HF or RF sputtering).
The novel method basically involves the controlled addition of hydrogen gas during the proper sputtering process. Thus, signif-icant improvements concerning the electrical properties of for example charge carrier concentration, charge carrier mobility and sheet resistance are achieved

Through the use of a counter-flow the air gets cleaned effectively and automatically from ash that is produced while the gasification of the wooden pellets. High temperature corrosion and fouling of the heat exchanger of a stirling engine can be reduced drastically. Up-to-date emission instructions can be reached at high effiency.
The invention describes a method to use of operating vibrations to determine the static stiffness of e.g. car bodies.
