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…
Scientists and engineers from the Universities of Bristol and Western Australia have developed how to efficiently simulate a “quantum walk” on a new design for…
A multi-institutional team of researchers has discovered novel magnetic behavior on the surface of a specialized material that holds promise for smaller, more…
When producing rear contact solar cells, both negatively and positively doped areas need to be produced on the rear of the solar cell. Moreover, the front side of the solar cell has to be sufficiently passivated in order to minimize surface recombination. This means three differently doped areas are required.
Scientists of the University of Konstanz have now developed a new method for producing these three areas in a single diffusion step. This approach is based on the application of a borosilicate glass layer and partial silicon nitride masking on the rear of the solar cell.
The recent work, published in the April issue of the journal Physics of Plasmas, focuses on the region at the edge in which the temperature and density drop…
New research by astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) examines a number of scenarios and finds that most of them have low…
Research at TU Eindhoven, KU Leuven and the University of Liege has shown how a motorcyclist riding right behind a racing cyclist can reduce the air resistance…
Microlasers are tiny optical devices a few tens of micrometres in diameter that are able to create intense light with only one colour or wavelength. OIST…
Since lasers were invented more than 50 years ago, they have transformed a diverse swath of technology — from CD players to surgical instruments.
Researchers in the group led by the Georg-H. Endress Professor Patrick Maletinsky have been conducting research into so-called nitrogen-vacancy centers (NV…
Quantum physics is more than 100 years old, but even today is still sometimes met with wonderment. This applies, for example, to entanglement, a quantum…
Cavitation – the formation, growth and subsequent collapse of microbubbles – produces high, localized energy which can be used in chemical processes for…
Scientists from all over the world are working on concepts for future quantum computers and their experimental realization. Commonly, a typical quantum…
In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as we are in the presence of two…
“Neutrinos are the fastest, lightest, most unsociable and least understood fundamental particles, and we are just now capable of detecting high-energy ones…
Scientists at the University of Stuttgart have developed an absorption chiller that is extremely compact, lightweight and stable in terms of operation, even at low evaporator temperatures and high heat rejection temperatures. Because of its compactness the absorption chiller has lower production costs and requires less refrigerant than conventional absorption chillers.
The invention discloses two chemical compound families derived from tetrahydrotriazine or coumarin selectively targeting the autophagic pathway.
