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.
