source:phys.orgRoom-temperature superconductivity has been a century-long-held dream of scientists. Hydrogen-rich compounds at high pressures are predicted to be potential high-temperature and even room-temperature superconductors and have become one of the superconducting materials that have received much attention in recent years.The superconducting transition temperatures of the covalent hydride H3S and ionic clathrate hydrides (LaH10, YH9, YH6) predicted theoretically and synthesized experimentally exceed 200 K, which are the most representative binary hydrides with high-temperature superc...

source:MININGRagnar Metals (ASX:RAG) says drilling is required to evaluate the potential of the Flaken prospect at its Olserum North Heavy Rare Earth (HREE) Project in southern Sweden, following results supporting the potential for rare earths mineralisation. A recent channel and rock sampling program in April added further context to a 3D modelling program conducted earlier this year. The company says the observations support the potential for a future discovery of a heavy rare earth oxide (HREO) deposit in the area. Ragnar, which has a market capitalisation of $8 million, says mode...

source:live scienceResearchers have discovered a way to purify rare-earth minerals from discarded gadgets with a chemical compound normally used in medicine. They claim their method offers multiple benefits for the environment.Rare-earth minerals, also known as rare-earth metals or rare-earth elements (REEs), include materials such as europium, yttrium, and samarium and have multiple uses in electronics. They are commonly found in smartphones, computers, TV screens and even electric car batteries.Despite their name, REEs are actually quite common but only occur naturally in low concentrations ...

source: Tokyo Institute of TechnologyImagine a thin film, just nanometers thick, that could store gigabytes of data—enough for movies, video games, and videos. This is the exciting potential of ferroelectric materials for memory storage. These materials have a unique arrangement of ions, resulting in two distinct polarization states analogous to 0 and 1 in binary code, which can be used for digital memory storage.These states are stable, meaning they can 'remember' data without power, and can be switched efficiently by applying a small electric field. This property makes them extremely...
