A POSTECH-KAIST joint research team has successfully developed a technique to reach near-unity efficiency of SHEL by using an artificially-designed metasurface.
Professor Junsuk Rho of POSTECH s departments of mechanical engineering and chemical engineering, and Ph.D. candidate Minkyung Kim and Dr. Dasol Lee of Department of Mechanical Engineering in collaboration with Professor Bumki Min and Hyukjoon Cho of the Department of Mechanical Engineering at KAIST have together proposed a technique to enhance the SHEL with near 100% efficiency using an anisotropic metasurface. For this, the joint research team designed a metasurface that transmits most light of one polarization and reflects the light from the other, verifying that the SHEL occurs in high-frequency region. These research findings were recently published in the February issue of Laser and Photonics Reviews, an authoritative journal in optics.
High energy storage batteries for EVs need high capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes but understanding how the magnesium and oxygen accommodate charge storage at high voltages is critical for their successful adaption. Research led by WMG, University of Warwick in collaboration with US researchers employed a range of X-ray studies to determine that the oxygen ions are facilitating the charge storage rather than the magnesium ions.

Some of the planet s rarest metals - used in the manufacture of smartphones and other electrical equipment - are increasingly being found in everyday consumer plastics, according to new research.
Scientists from the University of Plymouth and University of Illinois at Urbana-Champaign tested a range of new and used products including children s toys, office equipment and cosmetic containers.
Through a number of detailed assessments, they examined levels of rare earth elements (REEs) but also quantities of bromine and antimony, used as flame retardants in electrical equipment and a sign of the presence of recycled electronic plastic.
The results showed one or more REEs were found in 24 of the 31 products tested, including items where unregulated recycling is prohibited such as single-use food packaging.

Scientists from NUST MISIS have presented a technology for recycling lithium batteries for electric transport: electric buses, electric scooters, electric cars, etc. It represents a complete engineering cycle: from safe opening and determination of the amount of technogenic raw materials to be extracted and recycled to the introduction of processing lines. Recycling lithium batteries will reduce their cost by about 30-40% and solve the problem of safe and environmentally friendly storage. The technology can be used for the electric transport development program in Moscow.
