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: Mesoporous nanospheres are important in energy, catalysis, and sensor technology due to their multilevel architectures and tunable meso-structures. They can be obtained through aqueous polymer self-assembly and co-assembly-driven nanocomposite formation techniques using amphiphilic block copolymers and low-molecular-weight surfactants as soft templates.

Summary: The temperature-dependent bandgap in CsPbBr3 perovskites varies with material dimensionality, showing an initial blueshift followed by a redshift trend in 2D nanoplatelets. This shift is attributed to the larger contribution from electron-optical phonon interaction in nanoplatelets compared to nanocrystals, as indicated by the Bose-Einstein two-oscillator modeling. These findings provide valuable insights into the origin of temperature-dependent bandgap shifts in perovskite semiconductor materials.

Summary: Luminescent hollow micro- and nanocrystals were successfully obtained through self-assembly behavior and aggregation-induced emission enhancement properties. Utilizing oil-in-water droplets, spherical aggregates of about 200 or 50 nm with high stability were formed, emitting bright orange light. These crystals can also entrap hydrophobic drugs between alkyl chains, forming stable drug-loaded capsules in water.

Summary: The study demonstrates that eccentricity significantly influences the thermal stability of hollow nanoparticles, mainly due to the collapse caused by the irregular shell contour and thermal-activated diffusion process. At low temperature, the mechanism is mainly driven by the nucleation of stacking faults, gradually transitioning to amorphization as temperature increases, and some eccentric nanoparticles also undergo surface reconstruction process.

Summary: Graphene-assembled hollow nanospheres (GAHNs) have attracted much interest due to their outstanding multi-functional properties, including excellent compressive elasticity and plastic deformation characteristics. The morphology of force measurement tip plays a critical role in the compressive failure modes of GAHNs. With the increase of ambient temperature, the internal pressure of GAHN increases until a crack appears.
