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…

“Q-primers” are ammonium compounds, which make it possible to permanently functionalize virtually any surface. It is an environmentally friendly and cost-effective process that allows the production of ultra-thin layers and an “on demand” functionalization. The carrier quat primer can be equipped with any functional groups so that an universally applicable strategy for the modification of surfaces is now available.
