Summary: Hierarchical superstructured carbons (HSCs) assembled by low-dimensional fibers or sheets have great potential in energy applications due to their stable intersecting carbon network, large accessible surface area, and optimized ion transfer. A novel HSC is developed based on constructing sandwich-type alternate layered carbon/Zn2SiO4 composite by an intercalation growth strategy, featuring ultrathin graphene-like carbon nanosheets with a thickness less than 1 nm and a rigid and stable 3D network structure. The as-prepared HSC demonstrates superior performance in electronic double-layer capacitor with a combination of large accessible surface area and optimized nanostructure for ion transfer and electron immigration.

Summary: Zinc oxide arrays with various microscopic morphologies are grown on fluorine-doped tin oxide substrates using a hydrothermal method, with the relationship between microscopic morphologies and reaction conditions studied in depth. The concentration of free Zn2+ ions in the solution is found to be the key factor affecting microstructures. The competition between kinetic control and thermodynamic control during crystal growth is determined by the concentration of the free Zn2+ ions, leading to the formation of different microscopic morphologies.

Summary: The morphological properties of ZnO nanostructures such as nanorods, nanowires, and nanotubes can significantly affect their photocatalytic performance. In this study, the physical properties (optical and shape) of different 1-D ZnO nanostructures were evaluated in relation to their photocatalytic efficiency. ZnO nanorods transformed into nanowires under reduced seeding precursor concentration and into nanotubes with prolonged incubation time. The highest photocatalytic efficiency was observed in ZnO nanotubes, followed by ZnO nanowires and nanorods. The enhanced efficiency of ZnO nanotubes was attributed to their large polar face, high UV absorption, and large photocurrent density.

Summary: Based on dendrimers, a series of polyphenol compounds (P1, P2, and P3) were coordinated with iron (III) (Fe3+) to investigate the effect of polyphenol structures on their T1 contrast performance. These new Fe3+-based complexes, featuring regular amplification of their phenolic hydroxyl groups, exhibit enhanced longitudinal relaxivity (r1) due to proton exchange facilitated by a hydrogen-bonding network. Furthermore, these designed Fe3+-based complexes demonstrate good T1 contrast effect in vitro and in vivo. Modifying the coordination structure of Fe3+-based contrast agents can potentially improve their relaxivity properties and facilitate the development of excellent magnetic resonance imaging agents for disease diagnosis.

Summary: In this study, a synchronous nucleation pseudopyrolysis method was used to confine Fe/FeOx ultrafine nanoparticles (UNPs) in intact porous carbon nanorods (IPCNs). The strong physical and chemical confinement effects between UNPs and carbon were achieved through moderate thermal kinetics and abundant oxygen defects. This strong confinement greatly benefited subsequent chemical transformations and resulted in different Fe-based UNPs with excellent electrochemical performance. As a proof of concept, FeSe UNPs in IPCNs exhibited superior lithium storage performance with an ultrahigh and stable capacity of 815.1 mAh g-1 at 0.1 A g -1 and 379.7 mAh g-1 at 5 A g-1 for 1000 cycles.

Summary: The misuse of antibiotics has led to the emergence of drug-resistant bacteria, posing a serious public health threat. Antibacterial photodynamic therapy (aPDT) serves as a promising strategy to combat drug-resistant microbes. However, conventional photosensitizers have limited efficacy due to the complex bacterial infectious microenvironment (BIME). In this study, a BIME-triggered nanoplatform, HA-CY, was developed to enhance aPDT efficacy by exploiting the specific conditions of BIME.

Summary: The Cu2SnTe3 (CST) nano-reagent is able to effectively inhibit tumor growth through a strong synergetic effect in chemodynamic therapy (CDT), photodynamic therapy (PDT), and photothermal therapy. CST nanoparticles convert H2O2 into *OH and generate O-1(2) through surface-catalyzed reactions and light irradiation-induced electron pair separation, leading to oxidative stress accumulation in tumor cells. The nanoparticles also possess catalase-like activity, enhancing O-2 levels within hypoxic tumors and the production efficiency of O-1(2) by PDT.
