Abstract Scope |
Nanomaterials have garnered significant interest in enhancing the performance of energy harvesting systems, biomedical devices, and high-strength composites. Despite advances in fabricating elaborate and heterogeneous nanostructures, and characterizing them using TEM tomography, challenges still remain in achieving straightforward 3D visualization, due to complex fabrication processes, agglomeration issues, and non-uniform outputs. Here, we propose an in situ synthesis approach for fabricating complex, hierarchically-assembled ZnS nanostructures which comprise nanowire cores and nanoparticles catalyzed by Ag2S.This study marks the first successful synthesis of a heterogeneous nanostructure, utilizing the phase transformation mechanisms of vapor-liquid-solid for nanowires and vapor-solid for nanoparticles through precise temperature control. The resulting hierarchically-assembled ZnS nanostructures were characterized and their growth mechanisms were elucidated using the advanced TEM techniques. The electron tomography and 3D printing techniques allowed visualization of the nanostructures. This collaborative work is expected to open avenues for fabricating advanced and sophisticated nanostructures with potential applications in diverse fields. |
