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…
Diamondoids are molecules whose framework structure constitutes a section of the diamond lattice. Due to their size in the range of 0.5-2 nm, they can be considered as ?nano-diamonds? with a hydrogen-terminated surface.
Since they are extremely similar to diamonds and therefore possess many of their positive properties, diamondoids have the potential to serve as an enabling technology.
Scientists from Goethe University Frankfurt am Main have developed the so-called STRAP (Steering of Tonotopic Rate Adaptive Pitch) procedure for optimizing the stimulation strategy for cochlea implants. By position-dependent adjustment of the stimulation rate to each individual electrode, a much more precise pitch perception is achieved.
This development enables the simple, wet-chemical, microwave-assisted production of non-agglomerating nanoparticles (e.g. titanium oxide, zinc oxide, zirconium dioxide) from metal salts.
Key advantages of this development include the production of nanoparticles of variable sizes and the prevention of agglomeration.

This invention is a laser-arc hybrid welding process that uses a specially shaped electrode made of filler metal. Unlike conventional laser-arc welding processes, the coaxial arrangement of the individual processes results in a deeper penetration depth with increased process speed and improved inert gas efficacy. In addition, workpieces can be welded regardless of orientation and in forced position welding, because a change of direction does not result in any changes in the arrangement of the arc-electrode-laser beam.
