Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
RedVersIn provides an expression system that was specifically developed to match the high demands in the production of protein-based biopharmaceuticals in mammalian cells and is perfectly adapted to batch production systems. RedVersIn is also very useful in manufacturing proteins that are otherwise difficult to produce, especially for unstable and sensitive proteins as well as proteins that have cytotoxic or cytostatic properties. RedVersIn excels itself by a proven functionality in several of the industrially established mammalian cell lines and by being tunable and reversible with very fast reaction kinetics. RedVersIn is a reversible optically controlled gene expression system for mammalian cell systems based on the redlight-controlled Phytochrome. It allows an easy and powerful spatiotemporally induction of gene expression in cells, tissues and organisms.

This development allows for wet-chemical production of non-agglomerating nanoparticles (e.g. titanium oxide, zinc oxide) from metal salts. To do so, metal salts are mixed with a reaction and stability reagent. Amorphous or crystalline metal oxide nanoparticles can then be produced depending on the reaction calibration. These can be further processed during dispersion or separated from the solvent. The metal oxide nanoparticles obtained from this can be used in this form or dispersed in another solvent, e.g. water.

Der Schwingungssensor arbeitet mit zwei optischen Sensoren mit Fiber-Bragg-Gittern in Kombination mit einem Biegebalken und einer breitbandigen Lichtquelle. Beim Durchlauf durch die beiden FBG-Sensoren wird die Intensität des optischen Signals in Abhängigkeit der Biegung geändert. Die Intensität des Lichts kann einfach mit einem optischen Detektor gemessen werden. Eine aufwändige Analyse mittels eines
Spektrumanalysators entfällt. Aufgrund der hier gewählten Technologie ist es möglich, Schwingungen bis zu einer Frequenz von 100 kHz zu messen.
Die zur Herstellung notwendigen Technologien gehen nicht über die konventionellen Technologien hinaus,
so dass bei der Produktion des Sensors auf die bekannten Prozesse zurück gegriffen werden kann.
Entwickelt wurde die Technologie des
Schwingungssensors in erster Linie zur
Überwachung von Pipelines. Sie kann
aber in allen Gebieten eingesetzt
werden, in denen mechanische
Schwingungen bis zu 100 kHz detektiert
werden sollen.
