Valleytronics, which uses the valley degree of freedom of electrons to encode information, offers a promising route toward next-generation low-power electronic and optoelectronic devices. Researchers from Xiamen University have now shown that introducing graphene into a WS₂/CrBr₃ van der Waals heterostructure can dramatically accelerate interlayer spin-charge transfer, leading to giant valley polarization splitting and markedly improved circularly polarized light detection.

The design of unique fluorescent probes is of paramount importance for boosting the signal-to-noise ratio (SNR) and improving the sensitivity toward target analytes. Herein, researchers from the Xinjiang Technical Institute of Physics and Chemistry, Chinese Academy of Sciences have reported a hydrogen-bond-driven self-assembled sensing system (CdSe/ZnS QDs@FNAC) composed of quantum dots (QDs) capped with 3-mercaptopropionic acid (CdSe/ZnS QDs@MPA) and a naphthol-based molecular probe (FNAC). This system enables a ratiometric fluorescent dual-signal response toward KMnO₄ based on the synergistic mechanism of photoinduced electron transfer (PET) and twisted intramolecular charge transfer (TICT), featuring excellent sensing performance including a fast response speed (1 s), high sensitivity (4.80 nM), a favorable SNR, and negligible interference from other oxidants. The practicality of CdSe/ZnS QDs@FNAC was further verified by integrating a CdSe/ZnS QDs@FNAC-embedded hydrogel-based sensing chip into a portable detector, which enabled the on-site identification of ng-level KMnO₄ particles with high selectivity.

With the rapid development of electronic communication, aerospace, military and medical equipment, the demand for high‑performance electromagnetic interference (EMI) shielding materials has grown dramatically. A review article led by Prof. Ming‑Guo Ma from Beijing Forestry University systematically summarizes the latest progress in MXene/nanocellulose composites for EMI shielding. The work focuses on three key aspects: preparation strategies, toughening mechanisms (physical, chemical and synergistic), and multidimensional structural design (1D fibers, 2D layered films and 3D networks). The review also analyses current technological limitations and proposes future research directions, offering a roadmap for the rational design of high‑performance, flexible and lightweight EMI shielding composites.

A key challenge in transdermal delivery is maintaining consistent performance under dynamic conditions created by everyday user activities, such as skin bending, stretching, and movement. Addressing these real-world conditions is essential for both reliable drug delivery and user convenience. The bioinspired suction-activated nanofiber patch developed in this study achieves robust skin adhesion and consistent, enhanced transdermal delivery even under dynamic skin environments. By combining strong interfacial stability with user-friendly applications, this platform highlights a promising new direction for next-generation transdermal drug delivery systems.

Tanshinones—the bioactive compounds responsible for the cardiovascular benefits of the traditional Chinese medicinal herb Salvia miltiorrhiza—accumulate at relatively low levels in the plant, limiting their therapeutic and commercial potential. 

Bone repair depends on skeletal progenitor cells (SPCs) moving to injured areas and developing into bone-forming cells, but how these cells respond to their surroundings remains unclear. A study published in the International Journal of Oral Science shows that two collagen receptors, β1 integrin and DDR2, work together to regulate SPC migration, proliferation, and differentiation during cranial bone regeneration. The findings reveal a cooperative mechanism that could guide strategies to enhance bone repair.

Digital pathology relies on high-resolution imaging for accurate cancer diagnosis, yet high-magnification systems remain slow and costly for large-scale screening. Meanwhile, standard AI super-resolution often generates hallucinated cellular artifacts that risk diagnostic accuracy. To overcome this, researchers developed a hybrid bright-dark field computational framework using fast LED illumination to provide physical guidance. This physics-guided approach doubles spatial resolution, reduces reconstruction artifacts by 84%, and boosts AI cancer screening sensitivity by 11.14%.
