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…
Valence-free open nanoparticle superlattices
Binay P. Nayak, Zinnia Mallick, Wenjie Wang +7
A cornerstone of advanced materials design is establishing a framework for assembling nanoparticle superstructures with tailored symmetries. A longstanding challenge has been assem…
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…
Facile Salt-Assisted Hydrothermal Synthesis of Nanodiamonds from CHO Precursors: Atomic-Scale Mechanistic Insights
Soumya Pratap Tripathy, Sayan Saha, Saurabh Kumar Gupta +14
Hydrothermal synthesis offers an economical and scalable way to produce nanodiamonds under relatively mild, low-pressure and low-temperature conditions. However,its sustainability…
Specific Iron Binding to Natural Sphingomyelin Membrane Induced by Non-Specific Co-Solutes
Wenjie Wang, Honghu Zhang, Binay P. Nayak +1
Hypothesis: Sphingomyelin (SPM), a crucial phospholipid in the myelin sheath, is vital in insulating nerve fibers. We hypothesize that iron ions selectively bind to the phosphatidy…
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…
