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…
There are many processes, such as propulsion, in which fluid in a supercritical state, where the temperature and pressure put a substance beyond a…
Researchers at Northwestern University have created a new method to extract the static and dynamic structure of complex chemical systems. In this context,…
Three years ago, a University of Utah-led team discovered that an ultra-compact dwarf galaxy contained a supermassive black hole, then the smallest known…
A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in…
However, a new paper by an international team of scientists in the Proceedings of the National Academy of Sciences (PNAS) investigates an alternative…
The invention provides novel lithium salts of pentafluorophenylamide, in particular, lithium pentafluorophenyl (trifluoromethylsulfonyl)imide (Li-PFTFSI). Li-PFTFSI has improved thermal stability and ion mobility compared to known lithium salts.
These characteristics make Li-PFTFSI desirable for use as electrolytes in lithium ion batteries.
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called…
The anatase crystal form of Titanium dioxide (TiO₂) is one of the most promising materials for photovoltaic and photocatalytic applications nowadays. Despite…
Mesons are unstable particles coming into being, among others, as a result of proton collisions in the Large Hadron Collider (LHC) at CERN near Geneva….
Researchers at MPQ, ICFO, University of Innsbruck and the Center for Theoretical Physics of the Polish Academy of Sciences have developed a new method to show…
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a…
Due to the strong pull of gravity, not even light can escape from black holes, whose surface, i.e., the event horizon, cannot be observed directly. However,…
“MAVEN has made the first direct detection of the permanent presence of metal ions in the ionosphere of a planet other than Earth,” said Joseph Grebowsky of…
Computer electronics are shrinking to small-enough sizes that the very electrical currents underlying their functions can no longer be used for logic…
Stars are born when a cloud of gas hundreds of times more massive than our Sun begins to collapse under its own gravity. In the densest regions, protostars…
