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…

This innovative carbonization process of carbon precursor fibers creates in a fast and energy saving manner carbon fibers (CF) which are highly porous (small pore diameters from 0.1 to 10 nm) and have a high surface area (100 to 2500 m2/g). The pyrolysis step needs only minutes or even seconds.
No additional additives like pore-providing templates, catalytic compounds or corrosive liquids are required. However, filler materials like pigments, dyes, graphene nanoplatelets or metal- and semiconductor nanoparticles can be admixed to vary the performance of the produced carbon fibers, e.g. to increase electrical conductivity. Overall, this technology combines conventional carbonization and activation treatments into one process and is more economical by saving time, costs and resources compared to already known thermal carbonization methods.
Applications of carbon fibers are known in the art. Electric applications like super caps and electrodes or filtration and adsorption for gas, water and solvent purification might be preferable.
A herbal remedy is effective against the Ebola virus. The natural compound silvestrol reduces the number of pathogens in infected cells. Also the production of virulent proteins is largely suppressed if the natural substance is used.
