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…
A molecular rectifier comprised of a diamondoid molecule and an electron acceptor attached to the diamondoid molecule is now available. The electron acceptor is generally an electron accepting aromatic species covalently attached to the diamondoid. Hereby, the diamondoid molecule fulfills the role of an electron donor.<p>
It has been discovered that rectification at the molecular level can be achieved by combining a diamondoid molecule with an electron acceptor ? most notably an aromatic one. Depending upon the particular combination of diamondoid molecule with electron acceptor, these molecules may act as rectifiers, resistors, p-n junctions, or a combination thereof.
