On March 11, 2025, at the China Collective Stand of the London Book Fair, Tsinghua University Press (TUP) and the University of Toronto Press (UTP) sign a licensing agreement for the English version of Harnessing Data for Improved Productivity: Managing the Full Life Cycle of Data.
Traffic congestion and its inherent stochasticity continue to challenge urban mobility worldwide. To address this, researchers have introduced a groundbreaking framework for modeling the Stochastic Fundamental Diagram (SFD) from microscopic interactions. It not only deepens our understanding of stochasticity in traffic flow, but also paves the way for advanced longitudinal control strategies in connected and automated vehicles (CAVs) to minimize the stochasticity and enhance the overall traffic.
High Curie temperature and high piezoelectric constant are challenges that most piezoelectric ceramics difficult to be achieved simultaneously. Bismuth-layered CaBi4Ti4O15 (CBT) piezoelectric ceramics exhibit a high Curie temperature (790°C), but the piezoelectric constant is only 8 pC/N. This work uses WCo/Mn ions co-doping to modify CBT piezoelectric ceramics: by designing B-site composite ions to induce [TiO6] structural distortion, reduce the domain size, and enhance the domain switching under low electric fields. The CBTWC-0.1Mn ceramic achieves a high piezoelectric coefficient of 27.3 pC/N, and the piezoelectric constant remains largely unchanged after high-temperature annealing, demonstrating significant advantages in the field of high-temperature piezoelectric applications.
A research team from Southern University of Science and Technology discovered a small polaron effect induced by a giant deformation potential in Dion-Jacobson phase two-dimensional (2D) lead halide perovskites. The study provides direct evidence of the interplay between charge carriers and the lattice, showing up to a tenfold increase in spin lifetime, significantly improving optoelectronic properties. This discovery offers new insights into the design of high-performance materials and devices for next-generation optoelectronics.
A team of researchers led by Dr. Chengzhou Zhu at Central China Normal University has made a significant breakthrough in the field of photoelectrochemical (PEC) sensing by developing a novel p-n junction with atomic-level doping. The study, published in National Science Review, demonstrates how the deliberate modulation of interfacial chemical bonds can significantly enhance charge transfer and photoelectric response, paving the way for advanced biosensing applications.
A research team led by Prof. Liangliang Dai of Northwestern Polytechnical University (NWPU) has launched a platelets-based drug delivery system. The study was published in Science Bulletin.
Metastasis and heterogeneity pose major challenges in cancer treatment. Although chemoimmunotherapy shows promising efficacy, its therapeutic impact is limited by off-target effects and differences in the delivery sites of chemotherapeutic drugs and immunosuppressants. To overcome the limitation, the research team proposed an engineered platelets (Pts)-based nano-aircraft, Pts@DOX/HANGs@Gal, was constructed with an internally loaded chemotherapeutic drug, doxorubicin, and externally grafted reduction-responsive hyaluronidase-cross-linked nanospheroids loaded with the immunosuppressant galunisertib for precise tumor chemo-immunotherapy.
A study in Reproductive and Developmental Medicine links elevated levels of the KLF12 protein to impaired placental development, a major cause of unexplained miscarriages affecting 15% of pregnancies. Researchers found higher KLF12 levels in miscarriage cases, which inhibit the GCM1 gene critical for placental cell fusion. KLF12 could serve as a biomarker for miscarriage risk, and targeting its regulation may improve placental function and reduce miscarriages.
Researchers from the University of Science and Technology of China have uncovered the electrodissolution mechanism of zinc electrodes in aqueous zinc-based batteries, providing new insights for improving zinc electrode reversibility. The findings were published in Science Bulletin under the title "Electrodissolution-Driven Enhancement in Zn Electrode Reversibility."
