Kinetic Criticality in Linker-Mediated Colloidal Aggregation
Alexei V. Tkachenko, Soojung Lee, Zohar A. Arnon +1
Linker-mediated aggregation plays an important role in modern nanoscience. We demonstrate that it departs sharply from classical Smoluchowski kinetics because cluster reactivity ev…
Structural and Compositional Complexities of Hierarchical Self-Assembly: a Hypergraph Approach
Alexei V. Tkachenko
Programmable self-assembly enables the construction of complex molecular, supramolecular, and crystalline architectures from well-designed building blocks. We introduce a hypergrap…
Universality in diffusion-controlled nucleation and growth
Alexei V. Tkachenko
Nucleation and growth is studied in a system undergoing diffusion-controlled condensation under gradual changes in parameters, such as cooling. It is demonstrated that when Gibbs-T…
Symmetry-specific characterization of bond orientation order in DNA-assembled nanoparticle lattices
Jack A. Logan, Aaron Michelson, Ajith Pattammattel +3
Bond-orientational order in DNA-assembled nanoparticle lattices is explored with the help of recently introduced Symmetry-specific Bond Order Parameters (SymBOPs). This approach pr…
