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…
The new type of solar cells contains copper oxide phases as a photovoltaic absorber film in combination with e.g. AlGaN, ZnMgO, or ZnBeO thin film. These are non-toxic and their production is possible in industrial scale (e.g. using the cathode sputtering technique) and with low energy consumption.
Princeton University researchers have built a new computer chip that promises to boost performance of data centers that lie at the core of online services from…
Food-borne salmonella infections are mostly arising from poultry or pigs. While actions have been taken for poultry there has only been minor success for a pig vaccine. Scientists at the University of Veterinary Medicine Hanover developed a marker vaccine for pigs, which allows differentiation of vaccinated and infected animals.
The present innovation provides lid and housing of a container with magnets in order to connect those reversibly and safely with each other.
The researchers, led by a team at the University of Cambridge, have identified a key stage in the birth of a very massive star, and found that these stars form…
In the latest issue of Acta Crystallographica Section A: Foundations and Advances , Sarah Hoffmann-Urlaub and Tim Salditt report the fabrication and testing of…
Harvard astronomer Laura Schaefer (Harvard-Smithsonian Center for Astrophysics, or CfA) and her colleagues examined the question of what would happen to GJ…
Since the 1986 discovery of high-temperature superconductivity in copper-oxide compounds called cuprates, scientists have been trying to understand how these…
New technical solution to manage targeted communication between team members and to minimize noise in the operating theatre. This reduces stress for the operating staff and concomitantly mistakes. We offer the Silent Operating Theatre Optimisation System – “SOTOS”. Prototype tested and available.
The Ullmann reaction examined is a chemical reaction in which silver atoms catalyze the bond between two carbon atoms to which iodine was previously bonded….
Nobody said computer programming was easy. But maybe in the future, it could be.
Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according…
Controlling these instabilities leads to higher temperatures within tokamaks and thus more efficient fusion processes. The research was published in the August…
The Institute of Combustion and Power Plant Technology (IFK) of the University of Stuttgart has developed a measuring device for use in coal power plants. The device allows for permanent monitoring of the conditions inside the boiler, particularly of soot deposition.
Besides determining the deposition rate inside the boiler, growth characteristics, adhesion, ash qualities and waste disposal behavior with deposit as well as the extent to which these can be cleaned using soot blowers can be judged. Thus, the measuring device can indicate potential for optimization, e.g. of coal compositon in the fuel feed.
The prototype has been tested successfully.
The new method allows high laser intensities of any level. Thus, the novel backscattering sources generate X and Gamma-radiation with highest brilliance and intensity and low bandwidth.
A nanocrystalline material that rapidly makes white light out of blue light has been developed by KAUST researchers.
