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…

The Fischer-Tropsch synthesis is an important process to convert coal, natural gas and biomass to a variety of hydrocarbon products and oxygenates of different chain length.
In this modified Fischer-Tropsch process valuable nitrogen or phosphorous containing products of varying chain length are produced via co-feeding of suitable gases such as ammonia. These nitrogen-containing products include amines but also nitriles, amides and formamides. Amines and nitriles are important base chemicals and they are typically produced from oxygenates precursors which themselves are derived from olefins. This process therefore eliminates the use of a two-step process. Similarly phosphorous containing compounds can be produced. Moreover, the formation of oxygenates including carboxylic acids which are undesired products of the synthesis can be fully suppressed with the modified process. Notably this can be achieved with no or tolerable loss of catalyst activity.
