Scientists at PPPL have gained new insight into a common type of plasma hiccup that interferes with fusion reactions. These findings could help bring fusion energy closer to reality.
Materials scientists have synthesized a new type of perovskite--one of the most common crystal structures of materials deployed for a range of uses, from superconductors to photovoltaics--that goes against conventional thinking about how such structures behave at extreme pressures such as those that exist deep in the Earth.
New research has shown that Drax power station in North Yorkshire is the optimal site for the carbon capture and storage facilities that will be needed reduce carbon emissions and achieve the targets of 2016 Paris Climate Agreement.
Explosive volcanic eruptions are possible deep down in the sea -- although the water masses exert enormous pressure there. An international team now reports how this can happen.
Superconducting coils in a fusion power reactor exert a huge electromagnetic force. The coils are supported by a structure of solid build. A group of fusion engineering researchers of the National Institute for Fusion Science, National Institute of Natural Sciences first applied topology optimization to the design of a helical fusion reactor. The group succeeded in reducing the weight of the coil support structure by about 25% while maintaining the strength.
In order to realize fusion energy, it is economically desirable to confine higher pressure plasma with the same strength of the magnetic field. A research team of fusion scientists has succeeded using computer simulation in reproducing the high-pressure plasma confinement observed in the Large Helical Device. This result has enabled highly accurate predictions of plasma behavior aimed at realizing an economical helical fusion reactor.
A new mathematical model for predicting variations in solar irradiance has been developed at Uppsala University. It may help to promote more efficient use of electricity from solar energy. In tests of various data models, the model proved capable of making highly reliable forecasts, and emerged as the best for this purpose in some respects. The results have now been published in two articles in the journal Solar Energy.
Looking for rational design of new types of OER electrocatalysts and addressing fundamental questions about the key reactions in energy conversion, the inter-institutional MPG-consortium MAXNET Energy integrated the scientists from different institutions in Germany and abroad.
A team led by the Department of Energy's Oak Ridge National Laboratory used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.
Imperial College London researchers have demonstrated how machine learning could help design lithium-ion batteries and fuel cells with better performance.
