Phosphine (PH3) is a deadly industrial byproduct that poses a severe threat to human health and the environment. A research team from Yunnan Minzu University and Kunming University of Science and Technology has developed a sustainable "waste-to-wealth" strategy that captures toxic PH3 tail gas and transforms it in situ into a robust Ni2P/Ni5P4 heterostructure electrocatalyst. This innovative approach not only achieves high-efficiency gas purification but also provides a low-cost, high-performance solution for green hydrogen production, bridging the gap between pollution control and clean energy.
Professor Zhang Yuxin's team from Chongqing University, specializing in new silicon algae material innovation, used natural diatom (DE) as the base to in-situ grow layered hierarchical SZIF-8 carriers, loaded sodium molybdate corrosion inhibitor to construct Na₂MoO₄@SZIF-8-DE intelligent filler, and combined with E51 epoxy resin to prepare an adaptive anti-corrosion coating.
Flexible thermoelectric generators offer a promising route to harvest body heat for wearable electronics, but balancing high output, mechanical flexibility, and long-term stability remains challenging. A research team has developed Bi2Te3/HPMC@paper-based flexible thermoelectric generators with planar and multilayer-stacked architectures, achieving enhanced flexibility and thermoelectric performance. The Level-III stacked device delivered a device-level Seebeck coefficient of 11,330.25 μV·K-1 and a maximum output power of 617.4 nW, demonstrating potential for wearable thermal energy harvesting.
The reverse water-gas shift (RWGS) reaction converts CO2 and H2 into CO, an important feedstock for fuels and chemicals, but its broader use is limited by low-temperature conversion, competing methanation and high-temperature energy demand. The comprehensive review organizes recent progress in Pt-based catalysts around five structural design strategies and links them with in-situ and operando characterization and theoretical modeling, providing a unified framework for identifying working-state active sites and guiding catalyst design.
Our findings demonstrate that hnRNPA2B1-dependent m6A modification of circSMAD6 accelerates aerobic glycolysis and metastasis of HCC cells by regulating miR-30d-3p/CNPY2 axis, and may provide a potential therapeutic target for HCC.
