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…
Achieving economic and environmental viability of hydrogen production through water splitting especially using energy derived from green and sustainable sources is the hallmark of the hydrogen economy. In this invention non-precious metal containing catalysts replacing platinum group metal-based ones are introduced which is key to enable cost-effective water splitting and affordable fuel cells.
Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, new research strongly suggests.
The Snail/Gfi1 (SNAG) family of zinc finger proteins is a group of transcriptional repressors. Gfi1 is expressed in the hematopoietic and nervous system. Consequently, mutations of Gfi1 cause defects in hematopoiesis and inner ear development. In the Gfi1P2A/P2A mouse strain, a point mutation has been inserted in the SNAG domain that replaces a proline at amino acid position 2 by alanine (P2A). This completely abrogates the activity of Gfi1 as transcriptional repressor. Gfi1 and its paralogue Gfi1b have overlapping, however differential functions in hematopoiesis. Loss of Gfi1 in mice affects pre-T-cell differentiation, the development of neutrophil granulocytes and inner ear hair cells, whereas in contrast loss of Gfi1b impairs the development of erythroid cells and megacaryocytes. Therefore, Gfi1P2A/P2A mice can be used as a model to study and treat deafness as a consequence of defects of inner ear development as well as defects of hematopoiesis in immunological disorders.

Bei der vorliegenden Erfindung handelt es sich um ein Verfahren zur Herstellung dünner Polymer-Elektrolyte, die zudem mechanisch stabil und gleichzeitig auch flexibel sind. Diese zeichnen sich durch gute ionische Transporteigenschaften aus, d.h. die Leitfähigkeit bei Raumtemperatur beträgt 1 mS/cm. Die Membranen können aufgrund ihrer mechanischen Eigenschaften in Lithium-basierten Energiespeichen gleichzeitig als Elektrolyt und Separator eingesetzt werden. Das Verfahren ermöglicht die Verarbeitung von Polyacrylnitril basierten Membranen zusammen mit dem Lithiumleitsalz und ermöglicht eine gleichmäßige Materialstärke.
The invention consists of a cooled cylinder unit for a rheometer
and a method to identify rheological properties. By use of the
invention the cooling time in convective cooled rheometers can be
reduced. This can be necessary to reduce or prevent thermal
degradation of thermal sensitive polymers (i.e. biobased or bio-
degradable polymers).
