Chiral inorganic nanomaterials hold significant promise for various applications, including enantioselective catalysis, polarization-controlling optical devices, metamaterials, and molecular sensors. In our previous work, we presented a method synthesizing chiral Au 432 helicoid III (Au helicoids) from peptides amino acids, where helical gaps are intricately arranged with symmetry within single cubic nanoparticles. this study, have achieved the fabrication of silica molds through etching...
Enzymes in nature efficiently catalyze chiral organic molecules by elaborately tuning the geometrical arrangement of atoms active site. However, enantioselective oxidation heterogeneous electrocatalysts is challenging because difficulty controlling asymmetric structures sites on electrodes. Here, we show that distribution kink high-index facets can be precisely manipulated even single gold nanoparticles; and this enabled stereoselective hydroxyl groups various sugar molecules. We...
Abstract Anisotropic gold nanoplates (NPLs) have raised the interesting possibility that their reduced geometrical symmetry allows fine tuning of optical properties associated with excitation localized surface plasmon resonances (LSPRs). Recent developments greatly improved LSPR tunability by utilizing spatial distribution modes. However, nanoscale interplay between defect‐induced mechanical strain and variation modes remains poorly understood. In this work, combination high spatial‐...
Characterizing the spatial distribution of electromagnetic fields a plasmonic nanoparticle is crucial for exploiting its strong light-matter interaction optoelectronic and catalytic applications. However, observing near-fields in three dimensions with high resolution still challenging. To realize efficient three-dimensional (3D) nanoscale mapping nanoparticles complex shapes, this work established autoencoder-embedded electron energy loss spectroscopy (EELS) tomography. A 432-symmetric...
Developing robust anodes for the electrochemical chlorine evolution reaction (CER) is critical producing chlorine, an essential commodity various industries. Dimensionally stable (DSAs), typically composed of Ti substrates and mixed metal oxide catalysts such as IrO2–RuO2–TiO2, are current state-of-the-art industrial CER anodes. To achieve high stability DSAs, designing catalytic systems based on understanding failure mechanism a crucial strategy. This study investigates mechanisms...
