The research team led by Professor Jun He from Wuhan University has developed a universal metal-assisted epitaxy strategy to produce wafer-scale monolayer MoS₂ films with specific substitutional doping on commercial insulator substrates of c-plane sapphire. By precisely introducing dopants, the carrier types of monolayer MoS₂ films can be effectively modulated, evidenced by the theory calculations and multi-scale characterizations. Consequently, transistors with high mobility (≈ 71.2 cm²V⁻¹s⁻¹) and on/off current ratio (≈ 10⁸), as well as low-power inverters, are obtained. Finally, we developed a standard gate-last process for integrating hundreds of thousands of gate level modulation-doped MoS₂ array devices on a 4-inch wafer, and demonstrated their applications in digital logic circuits such as data selector, 3-to-8 decoder and full adder. These results advance the development of controllable synthesis technology for wafer-scale 2D modulation-doped semiconductors and pave the way for their practical applications in integrated electronics.

Recent theoretical research suggests that charmed baryon decays may exhibit unexpectedly large CP violation, potentially offering new clues to the matter-antimatter asymmetry in the universe. Based on the final-state re-scattering, the study predicts CP violation to be an order of magnitude larger than previous estimates. These findings highlight promising opportunities for experimental verification at current facilities like BESIII, LHCb, and Belle II, as well as the upcoming Super Tau-Charm Facility (STCF).

Single-atom nanozymes (SAzymes) hold significant potential for tumor catalytic therapy, but their effectiveness is often compromised by low catalytic efficiency within tumor microenvironment. This efficiency is mainly influenced by key factors including hydrogen peroxide (H₂O₂) availability, acidity, and temperature. Simultaneous optimization of these key factors presents a significant challenge for tumor catalytic therapy. In this study, we developed a comprehensive strategy to refine single-atom catalytic kinetics for enhancing tumor catalytic therapy through dual-enzyme-driven cascade reactions. Iridium (Ir) SAzymes with high catalytic activity and natural enzyme glucose oxidase (GOx) were utilized to construct the cascade reaction system. GOx was loaded by Ir SAzymes due to its large surface area. Then, the dual-enzyme-driven cascade reaction system was modified by cancer cell membranes for improving biocompatibility and achieving tumor homologous targeting ability. GOx catalysis reaction could produce abundant H₂O₂ and lower the local pH, thereby optimizing key reaction-limiting factors. Additionally, upon laser irradiation, Ir SAzymes could raise local temperature, further enhancing the catalytic efficiency of dual-enzyme system. This comprehensive optimization maximized the performance of Ir SAzymes, significantly improving the efficiency of catalytic therapy. Our findings present a strategy of refining single-atom catalytic kinetics for tumor homologous-targeted catalytic therapy.

A team led by Professor Wang Tao at Tianjin University’s School of Life Sciences has uncovered how the Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) suppresses host cell apoptosis, enabling its replication. Their study, published in Science Bulletin, reveals that SFTSV exploits the MDM2-p53 signaling pathway to inhibit the formation of apoptotic complexes, a mechanism countered by the anticancer drug RG7388 (Idasanutlin). By blocking MDM2, RG7388 restores apoptotic sensitivity in infected cells, curbing viral propagation during early infection. The findings also illuminate broader therapeutic strategies for related viral threats.
