Summary: Hollow mesoporous silica nanospheres were synthesized using pentablock copolymer templates under acidic aqueous conditions, with tetraethyl orthosilicate as the silica precursor. The structure could be tuned by using different length pentablock copolymer templates, resulting in variations in pore structure and morphology. The samples demonstrated hydrothermal stability and the formation of hollow mesopore structures under room temperature conditions.

Summary: This study presents a facile method for the synthesis of unconventional amorphous hollow-silica nanostructures with controllable surface curvatures, symmetries, and interior architectures. The key role of transiently in situ crystallized metal coordination complexes as a template is identified for the differential silica growth that produces different nanostructures. Furthermore, crystal-like well-defined polygonal h-SiNSs can be assembled into highly ordered mesoscale materials with customizable cavities and nanospaces, which differ from conventionally assembled materials.

Summary: In this study, hollow-structured hydroxy vanadium oxide (VOOH) was constructed, and VOOH@MXene composite material was prepared through electrostatic self-assembly. The composites have effective attenuation and absorption of electromagnetic waves. The excellent conductivity of MXene compensates for the low conductivity of VOOH, and the hollow structure of VOOH prevents the stacking of MXene sheet layers and improves the impedance matching problem. The VOM_10 composite exhibits good microwave absorption performance with a minimum reflection loss of -34.9 dB and a maximum effective absorption bandwidth of 4.08 GHz. The preparation of VOOH@MXene composites using electrostatic self-assembly and the construction of a hollow structure provide a new idea for the study of lightweight and high-performance wave absorption materials.

Summary: Hollow mesoporous silica microspheres (HMSN) were used as carriers to store 2-aminino-5-mercato-1,3,4-thiadizole (ATM) in this experiment. The synthesised microspheres were uniformly dispersed with a diameter of approximately 500 nm, as confirmed by scanning electron microscopy. HMSN, as excellent nanocarriers, were employed to encapsulate ATM with a loading rate of 19 wt%. The addition of 18 wt% HMSN loaded with ATM to the coating improved the self-healing ability of the coating. Electrochemical impedance spectroscopy and scanning Kelvin probes were utilized to investigate the corrosion resistance of the coating.
