Electrostatic Superlattices beyond 1:1 Stoichiometry
Binay P. Nayak, Prapti Kakkar, Wesley P. Korba +5
Exotic nanoparticle superstructures can be accessed by harnessing nanoparticle softness and charge regulation, features often viewed as obstacles to structural control. Here, we sh…
Electrostatically Assembled Open Square and Checkerboard Superlattices
Binay P. Nayak, Wenjie Wang, Honghu Zhang +4
Programmable assembly of nanoparticles into structures other than hexagonal lattices remains challenging. Assembling an open checkerboard or square lattice is harder to achieve com…
Extending the capillary wave model to include the effect of bending rigidity: X-ray reflectivity and diffuse scattering
Chen Shen, Honghu Zhang, Beate Klösgen +1
The surface roughness of a thin film at a liquid interface exhibits contributions of thermally excited fluctuations. This thermal roughness depends on temperature (T), surface tens…
Effect of Grafting Density on the Two-dimensional Assembly of Nanoparticles
Binay P. Nayak, James Ethan Batey, Hyeong Jin Kim +5
Employing grazing-incidence small-angle X-ray scattering (GISAXS) and X-ray reflectivity (XRR), we demonstrate that films composed of polyethylene glycol (PEG)-grafted silver nanop…
