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 novel Fourier Transform Infrared (FTIR) spectroscopy based approach for rapid and reliable differentiation of fresh from frozen/thawed meat or fish. This fast and inexpensive high throughput technique represents a powerful tool to ascertain correct labeling of meat and fish.
Gerät zur Messung von mechanischen Eigenschaften von Böden und Oberflächen, dass ohne Führungselemente auskommt, keine Sensoren für Weg oder Geschwindigkeit benötigt und Energierückgewinnung, Federkonstante, Kraftreduktion und Resonanzfrequenz misst.
Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have successfully tested a new device that will lead to a better…
To reach temperatures closely above absolute zero at −273.16 °C the demagnetization of magnetic materials under adiabatic, i.e., thermally insulated,…
These diamond-shaped nanoclusters (see Figure), consisting of a silver core of 2 to 3 nanometers and a protecting layer of silver atoms and organic thiol…
MIT researchers and their colleagues are designing an imaging system that can read closed books.
Most basic physics textbooks describe laser light in fairly simple terms: a beam travels directly from one point to another and, unless it strikes a mirror or…
Already in 1878, the first studies of sand moving on a vibrating plate were done by Ernst Chladni, known as the father of acoustics. Chladni discovered that…
Random number generators are crucial to the encryption that protects our privacy and security when engaging in digital transactions such as buying products…
Inventors of Saarland University achieved to develop new neutral bis azainositol heavy metal complexes suitable for the use as X-ray contrast agents with a wide range of advantages compared to common contrast agents. For their higher absorption coefficient in the range of voltages used in CT these complexes lead to scan protocols that provide equivalent or even improved diagnostic value at lower radiation doses compared to conventional triiodinated contrast agents.
High-resolution in user Field of View (FoV) is required to foster a sense of immersion in VR video applications such as multiple times UHD resolution to cover…
Solitons are localized waves that act like particles: as they travel across space, they hold their shape and form rather than dispersing as other waves do.
Until now, unbreakable encrypted messages were transmitted via a system envisioned by American mathematician Claude Shannon, considered the “father of…
Experiments using the OMEGA laser at the University's Laboratory of Laser Energetics (LLE) have created the conditions capable of producing a fusion yield…
Researchers found that the thermal conductivity of superatom crystals is directly related to the rotational disorder within those structures. The findings were…
Sensitive sensors and other electronic and optoelectronic components require reliable capsulations, which withstand long-lasting environmental difficulty. Such housings, with grommets for electrical connections in surroundings with low air or rather gas pressure and in the vacuum technology, require particularly high standards.
