Researchers at Institute of Science Tokyo (Science Tokyo) have developed a new liquid–metal process that can recover freshwater and magnesium resources from the concentrated brine. By combining liquid-tin direct-contact distillation with vacuum degassing, the method removes chlorine- and sulfur-containing species from the tin and enables magnesium-rich precipitates, with MgO as the major crystalline phase, to be recovered during cooling. More than 99% of the magnesium taken up by the liquid tin was recovered.
A study from the Research Center for Materials Nanoarchitectonics (MANA), one of the centers under the National Institute for Materials Science (NIMS), presents a new method to decode hidden material disorder contained in complex photoluminescence spectra, paving the way for new optical diagnostics of material disorder in two-dimensional semiconductors and related light-emitting materials.
Researchers led by the University of Osaka have directly observed a heavy-fermion state forming at the interface between a one-atom-thick ytterbium–copper layer and a copper substrate. Using synchrotron-based measurements, they showed that electrons across the interface interact to create this unusual quantum state. The finding offers a new approach to designing low-dimensional quantum materials and may help enable previously unexplored phenomena, including unconventional superconductivity.
Researchers at the University of Osaka developed new mouse models of hypophosphatasia that reproduce dental symptoms seen in patients. The models showed that teeth, surrounding bone, and tooth-supporting tissues can be affected even when skeletal symptoms elsewhere are mild. Differences between the models suggest that specific genetic changes influence dental symptoms, providing a new platform for studying disease mechanisms and developing dental treatments tailored to severity.
All-solid-state lithium batteries promise enhanced safety, but the relatively high weight of conventional oxide solid electrolytes remains a challenge for improving gravimetric energy density. Researchers have discovered that a lightweight crystal framework, UCr4C4-type RbLi(Li3SiO4)2, acts as a high-speed lithium-ion conductor. While defect formation currently limits overall conduction in stoichiometric samples, overcoming this with lithium-rich composition design can unlock its full performance, paving the way for lighter, safer, and faster-charging battery technologies.
The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material’s average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this in CuCrP2S6, a van der Waals material that transitions from a non-centrosymmetric to a centrosymmetric average structure. The finding challenges the conventional view of BPVE and suggests a new strategy for enhancing photoelectric conversion.
