High-Resolution Scanning Tunneling Microscopy Characterization of Mixed Monolayer Protected Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Javier Reguera Gomez, Kellen Michael Harkness, Mauro Moglianetti

Gold nanoparticles protected by a binary mixture of thiolate molecules have a ligand shell that can spontaneously separate into nanoscale domains. Complex morphologies arise in such ligand shells, including striped, patchy, and Janus domains. Characterizat ...

Reversible Microscale Assembly of Nanoparticles Driven by the Phase Transition of a Thermotropic Liquid Crystal

Francesco Stellacci, Holger Frauenrath, Paulo Henrique Jacob Silva, Stephen Schrettl, Kellen Michael Harkness

The arrangement of nanoscale building blocks into patternswithmicroscale periodicity is challenging to achieve via self-assemblyprocesses. Here, we report on the phase-transition-driven collectiveassembly of gold nanoparticles in a thermotropic liquid crys ...

Scanning tunneling microscopy and small angle neutron scattering study of mixed monolayer protected gold nanoparticles in organic solvents

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez, Kellen Michael Harkness, Mauro Moglianetti, Marta Mameli

When a binary mixture of ligand molecules is used to coat gold nanoparticles, stripe-like domains can occur. These nanodomains confer nanoparticles unique structure-dependent properties. The domain structure has been characterized primarily using scanning ...
