Summary: A novel visible-light-driven SnIn4S8 nanosheet/TiO2 hollow sphere heterojunction with intimate contact structure was successfully constructed by hydrothermal process. The SISTOHS heterostructures exhibited outstanding photocatalytic performance and the optimized sample SISTOHS2 showed the highest photodegradation and photoreduction efficiencies. The rate constants of photodegradation and photoreduction over SISTOHS2 were significantly higher than those of the control samples. The systemic characterizations revealed that the improvement of photocatalytic performance was attributed to the double-shell interface, which enhanced the interaction between SnIn4S8 and TiO2, as well as the increased visible light harvesting ability and abundant reactive sites.

Summary: Yolk-shell structures are widely used in catalysis and energy storage. In this study, Mn2+ doped hierarchical CuS yolk-shell microspheres were synthesized and the influence of reaction time on their structure and morphology was investigated. A rational phenomenological approach was proposed to describe the formation mechanism of the yolk-shell structures, and it was found that Mn2+ doping improved the photoreduction performance.

Summary: Chiral metal-organic frameworks (MOFs) are a promising candidate as new chiral stationary phases (CSPs) for usage in HPLC due to their uniform and adjustable cavities, abundant chiral active sites and excellent chemical stability. In this study, monodisperse homochiral MOF [Co-2(D-cam)(2)(TMDP3)]@SiO2 core-shell composites were prepared using an in-situ growth method, showing improved column efficiency and chiral resolution ability compared to conventional MOF columns. This approach provides a promising platform for the practical applications of chiral MOFs in chiral separation.

Summary: A high-quality and large-sized hexagonal boron nitride (hBN) crystal was successfully grown in Ni-Cr solution at 1550°C by using a specially designed cooling protocol, reducing the total growth time. The study showed that the grown hBN film had a thickness of 300μm and achieved an area of up to 24mm² on a mechanically exfoliated hBN film. X-ray diffraction and Raman spectroscopy confirmed the high crystalline quality of the hBN crystal.

Summary: Core-shell particles consisting of poly-2-methylaniline (PMAN) and carbonyl iron (CI) were successfully prepared through dispersion polymerization. The surface of CI particles was modified using dopamine as a chemical grafting agent to enhance the affinity between PMAN particles and pure CI particles. The morphology, crystalline structure, magnetic behaviors, and sedimentation stability of the prepared PMAN/CI particles were studied, and the dispersion stability was found to be better than that of pure CI particles. The characteristics of the PMAN/CI particle-based magnetorheological fluid were measured using a rheometer.
