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."
Asynchronous dual-comb generated in single laser cavity offer potent tools for simplified coherent measurements, owing to the common mode rejection which spares the sophisticated locking systems. However, the limited dimensional inhomogeneity in monolithic cavity induces relatively small repetition-rate-difference, hindering high-speed measurements. In a recent research, a monolithic linear fiber laser with integrated multifunctional device employing polarization multiplexing is proposed and demonstrated for dual-comb acquisition speed enhancement. By tuning the inherent the integrated device, controllable asynchronous harmonic mode-locking gets boosted, which enables the multiplication of the equivalent repetition-rate-difference and produces more temporal interferograms via least common multiple principles. Harmonic-repetition-rate up to 2.3 GHz and acquisition speed over 244 kHz are obtained in experiments, faster by 2 orders of magnitudes than previous single-fiber-cavity dual-combs.
A new study reveals that a region in China’s Turpan-Hami Basin served as a refugium, or “Life oasis” for terrestrial plants during the end-Permian mass extinction, the most severe biological crisis since the Cambrian period.
