Skygazers at northern latitudes are familiar with the W-shaped star pattern of Cassiopeia the Queen. This circumpolar constellation is visible year-round near…
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.
This finding opens a new piece of discovery space in the extrasolar planet hunt: to uncover planets as far from their central stars as Jupiter and Saturn are…
The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding…
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.
