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…
What happens when the lights are turned out in the enormous clean room that currently houses NASA's James Webb Space Telescope?
High-harmonic lightwaves tailored on demand by crystal symmetry
A research team based in Graz and Villach has developed an exhaust gas analyser that detects tiny particles faster and more accurately.
The theoretical physicists Junior Professor Fabian Pauly and his postdoc Dr. Safa G. Bahoosh now succeeded in a team of experimental physicists and chemists in…
Metamaterials don't exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler…
Physicists from MIPT have predicted the existence of transparent composite media with unusual optical properties. Using graphics card based simulations,…
A dynamic safety concept has been implemented in the Industrie 4.0 demo production plant of the SmartFactoryKL consortium on the basis of an industrial,…
Physicists at the University of Iowa have proposed a new technique to detect and measure materials that give off weak magnetic signals or have no magnetic…
Traditional battery materials, e. g. for Li-ion batteries are brittle, thus not suitable for high capacity flexible batteries. Rigid organic redox polymer batteries have low volumetric energy and power density.
Using a new colloid consisting, of redox pol-ymer and graphene oxide that is trans-formed into reduced graphene oxide during preparation, thickness scalable cathodic and anodic battery materials reaching 1.3 mAh/cm2 for flexible and at least 21 mAh/cm2 for rigid materials are available. The new technologa offers the following advantages:
higher capacities materials for flexible batteries,
scalability 1 – 20 mAh/cm2,
tailord redox-potential and
non-toxic materials.

Three working groups from Heidelberg, Cologne and Potsdam are involved in a joint project to develop a new technology for astronomical research. The…
The terahertz waves span frequency ranges between the infrared spectrum (used, for example, for night vision) and gigahertz waves (which find their…
Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites conducted, in part, at the Department of…
Eruptions on the Sun's surface send clouds of electrically charged particles towards Earth, producing solar storms that–among other things–can trigger the…
Our constantly-changing sun sometimes erupts with bursts of light, solar material, or ultra-fast energized particles — collectively, these events contribute…
