Nanoclusters self-organize into centimeter-scale hierarchical assemblies

Phys.org  April 22, 2022 An international team of researchers (USA – Cornell University, Rochester Institute of Technology, Canada) has created synthetic nanoclusters from an organic–inorganic mesophase composed of monodisperse Cd37S18 magic-size cluster building blocks. The process produced “magic-size clusters” of 57 atoms, about 1.5 nanometers in length. Each of these nanoparticles had a shell of ligands that could interact with each other in such a way that they formed filaments several microns long and hundreds of nanometers wide. The filaments were periodically decorated with the magic-size clusters with perfect spacing between them. Enhanced patterning was achieved by controlling processing conditions, […]
