Nanoparticle Assembly and Oriented Attachment: Correlating Controlling Factors to the Resulting Structures.
TL;DR: In this paper , the fundamental principles for understanding particle assembly and attachment processes, and the controlling factors and resulting structures are discussed, and a review of recent progress in the field via examples of both experiments and modeling is presented.

Spiers Memorial Lecture: Assembly-based pathways of crystallization.
TL;DR: In this paper , the relationship between interfacial structure, interparticle forces, and attachment dynamics, discuss the consequences of size dependent phase stability, and examine the impact of the ligand functionalization of primary particles.

TL;DR: This work develops a theoretical framework where interactions at the molecular and macroscopic scales are rigorously coupled based on colloidal theory and atomistic molecular dynamics simulations and integrates these interactions into a predictive coarse-grained model that captures the pH-dependent reversibility and accurately matches small-angle X-ray scattering experiments at collective scales.
