Theoretical framework for modeling of intermixing in core-shell nanocrystals (NCs) with realistic kinetics

Solution-phase synthesis of metallic nanocrystals (NCs) can produce NCs with tailored non-equilibrium shapes, and e.g., core-shell compositional profiles for bimetallic NCs. These structures can be tailored to optimize properties for applications such as catalysis, but they are metastable and possible post-synthesis evolution would degrade properties.

Adaptive variational quantum computing approaches for response function calculations

Accurate simulations of Green’s functions and nonlinear susceptibilities for electron and spin systems are achieved with highly compressed circuits.

Tailored synthesis in nanoparticle permanent magnets (NPPMs)

CMI researchers from Ames National Laboratory conducted the activity for this highlight

Milled and unmilled: 1 GPa at 100C. ~50% density and XRD showed no change in lattice. Note that the milled powder heated much more quickly than the unmilled powder, indicating better interparticle connectivity due to reducing the large agglomerates.
