JMIR Publications this week released three News and Perspectives features on the latest digital health news: stories on how informed consent must be rethought for clinical trials involving AI; Canada’s proposed Safe Social Media Act and the Canadian Medical Association’s support; and a promising new autonomous oxygen titration device for health care.
High-entropy carbides are promising noble-metal-free catalysts for hydrogen evolution, yet the nanocrystals reported so far have all been dense solids, and their metallic constituents have been drawn mainly from groups IVB–VIB metals. Recently, a team of materials scientists led by Wen Ma from Inner Mongolia University of Technology, China, reported the first synthesis of hollow rare-earth-containing high-entropy carbides via a one-pot electroreduction process in molten salt at 800 °C. Simply changing the carbon source tailors the architecture from solid to hollow. In 1.0 M KOH, the dual-rare-earth carbide (HfNbTaTiZrCeY)C delivers an overpotential of 167 mV at 10 mA·cm-2, a Tafel slope of 58.8 mV·dec-1 and a charge-transfer resistance of 2.7 Ω, outperforming its single-rare-earth counterparts. This work provides a novel strategy for the design of high-performance non-noble metal-based catalysts.
The simultaneous achievement of ultra-high quality factor (Q×f) and near-zero temperature coefficient of resonant frequency (τf) remains a critical challenge for microwave dielectric ceramics in 5G/6G systems. Rare-earth vanadate zircon (AVO₄) ceramics are promising for high-frequency applications owing to their intrinsically low dielectric constant, and chemical stability. This work resolves the persistent dilemma between high Q×f and thermal stability in microwave dielectric ceramics, offering a reliable design framework and laying the essential material foundation for advanced microwave components in 5G and 6G networks.
