Sculpting the plasmonic responses of nanoparticles by directed electron beam irradiation
Kevin M. Roccapriore, Shin-Hum Cho, Andrew R. Lupini +2
Spatial confinement of matter in functional nanostructures has propelled these systems to the forefront of nanoscience, both as a playground for exotic physics and quantum phenomen…
Effects of linker flexibility on phase behavior and structure of linked colloidal gels
Michael P. Howard, Zachary M. Sherman, Adithya N Sreenivasan +4
Colloidal nanocrystal gels can be assembled using a difunctional "linker" molecule to mediate bonding between nanocrystals. The conditions for gelation and the structure of the gel…
Wertheim's thermodynamic perturbation theory with double-bond association and its application to colloid-linker mixtures
Michael P. Howard, Zachary M. Sherman, Delia J. Milliron +1
We extend Wertheim's thermodynamic perturbation theory to derive the association free energy of a multicomponent mixture for which double bonds can form between any two pairs of th…
Universal Gelation of Metal Oxide Nanocrystals via Depletion Attractions
Camila A. Saez Cabezas, Zachary M. Sherman, Michael P. Howard +6
Nanocrystal gelation provides a powerful framework to translate nanoscale properties into bulk materials and to engineer emergent properties through the assembled microstructure. H…
Structure and phase behavior of polymer-linked colloidal gels
Michael P. Howard, Ryan B. Jadrich, Beth A. Lindquist +4
Low-density "equilibrium" gels that consist of a percolated, kinetically arrested network of colloidal particles and are resilient to aging can be fabricated by restricting the num…
Intrinsic Optical and Electronic Properties from Quantitative Analysis of Plasmonic Semiconductor Nanocrystal Ensemble Optical Extinction
Stephen L. Gibbs, Corey M. Staller, Ankit Agrawal +3
The optical extinction spectra arising from localized surface plasmon resonance in doped semiconductor nanocrystals (NCs) have intensities and lineshapes determined by free charge…
