“…The as‐made nanoribbons had a main diffraction peak at 23.3°, attributed to (010) in WO x (FigureS1, Supporting Information). [ 10 ] The low‐magnification transmission electron microscopy (TEM) images ( Figure a; Figures S2 and S3, Supporting Information) of the WO x nanoribbons revealed that they were ≈50 nm long and ≈5 nm wide. The atomic‐resolution aberration‐corrected high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM) images of a few nanoribbons (Figure 1b,c; Figures S4 and S5, Supporting Information) illustrated that the thickness of the nanoribbons was mainly distributed at 0.9–1.1 nm.…”

The repair of bone defects in diabetes remains a major challenge in the field of biomedicine because of the disturbance of bone immune homeostasis and the susceptibility of exposed wounds to bacterial infection. Clinically, immunoregulation by removing excessive reactive oxygen species (ROS) effectively promotes diabetic bone defect repair. However, aggressive ROS clearance can disrupt ROS homeostasis, making ROS‐mediated polarization of M2 macrophages in the process of tissue healing of diabetes be difficult. Herein, an ultrathin defective tungsten oxide (WOx) nanoribbon with high oxygen vacancies to simultaneously achieve moderate scavenging of ROS and high broad‐spectrum photothermal antibacterial activity to promote diabetic bone defect repair is reported. It is demonstrated that the moderate ROS clearance ability of WOx nanoribbons can remodel metabolic patterns for achieving 86.3% M2 macrophage induction in a high glucose microenvironment. This high induction efficiency combined with excellent photothermal antibacterial ability of WOx nanoribbons markedly alleviated the inflammatory reaction and efficiently facilitated the repair of bone defects infected with methicillin‐resistant Staphylococcus aureus (S. aureus) in C57BLKS/J (BKS)‐diabetic (BKS‐db) mice.

The ring-opening polymerization lays the foundation for synthesizing polypropylene glycol (PPG). Nevertheless, homogeneous alkali catalysts generally necessitate intricate posttreatments, hampering green synthesis and ensuring environmental sustainability. Here, we develop a heterogeneous epoxide polymerization method based on a P123-modified nanocomposite layered double oxide (CoMgAl-LDO (P123)). Benefiting from the designable and self-assembled P123 micelles, CoMgAl-LDO (P123) yields intergranular gaps and consistent mesoporous channels for effective catalysis. Consequently, CoMgAl-LDO (P123) has a large surface-to-volume ratio of 190.0 m2 g− 1 and a pore volume of 1.0 cm3 g− 1. More importantly, the epoxide catalytic conversion approaches 96.3%, which is higher than the 92% conversion of other solid catalysts. Our strategy addresses the trade-off issue that alkali catalysts face in terms of sustainability and operational complexity, holding great promise in green chemistry.
