Since the morphology of nanoparticles directly influences many their properties, accurately determining shape is crucial for targeted applications. In this work, we focus on nanoprisms due to widespread use and limitations direct imaging techniques in describing polygonal cross section. Specifically, introduce a new tool small-angle scattering (SAS) analysis that requires minimal computation time compared with all-atom simulations other form factor analyses. A key innovation work...
Multicomponent self-assembly has been explored to create novel metamaterials from nanoparticles of different sizes and compositions, but the assembly with complementary shapes remains rare.Recent binary assemblies were mediated by DNA base pairing or induced solvent evaporation.Here, we introduce depletion-induced (DISA) as a approach for constructing tunable lattices.In situ structural analysis in real reciprocal spaces demonstrates DISA mixture octahedra tetrahedra into extended...
Supercrystals, extended lattices of closely packed nanoparticles (NPs), present exciting possibilities for various applications. Under high pressures, typically in the gigapascal (GPa) range, supercrystals undergo significant structural changes, including adjustable interparticle distances, phase transformations, and formation new nanostructures through coalescence. While prior research has focused on ligand engineering's impact supercrystal mechanical response, influence NP shape remains...
Solar-driven plasmonic photocatalysis has emerged as a powerful tool to enhance chemical reactivity, improving the efficiency and selectivity in large number of transformations. Plasmonic nanoparticles are often implemented colloidal dispersions but they face issues related reduced photoactivation metallic surface concentrated solutions poor long-term stability. To overcome these limitations, we introduce 3D supercrystals created through depletion- evaporation-induced self-assembly metal...
