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: In this study, hexagonal boron nitride nanoparticulates and graphene nanoplatelets reinforced aluminum matrix composites were produced via powder metallurgy process. The mechanical properties, including density, hardness, and compressive strength, were significantly improved in composites with 1%BN and 0.15%graphene content. However, exceeding these contents resulted in decreased mechanical strength due to the aggregation of graphene nanoplatelets and nano-BN particles.

Summary: To address challenges in bacterial infection without using antibiotics, a new approach of ionic liquid (IL)-promoted simultaneous exfoliation and conjugation of boron nitride nanosheets (BNNSs) with ammonium dimolybdate (ADM) has been developed. The BNNS-IL-ADM provides sustained release of molybdenum ions, resulting in improved antibacterial efficiency against E. coli and S. aureus. The enhanced antibacterial performance is attributed to the synergistic effect between BN nanocarrier and bioactive ADM, as well as the nanoconfinement capability of BNNS-IL-ADM.

Summary: By studying the dynamics of polarization and evolution of domain structure in ferroelectric Al0.93B0.07N, it was found that applying negative unipolar and bipolar reverse curve waveforms led to surface feature changes and a decrease in electromechanical response, while positive biases did not cause surface changes. Stable polarization patterns were observed in a controlled atmosphere, but even in this environment, surface ions may still participate in polarization switching phenomena and ionic compensation.
