Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti, Evgeniy Ponomarev

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Co-precipitation of oppositely charged nanoparticles: the case of mixed ligand nanoparticles

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti, Evgeniy Ponomarev, Maxime Tomasz Szybowski

Colloid stability is of high importance in a multitude of fields ranging from food science to biotechnology. There is strong interest in studying the stability of small particles (of a size of a few nanometres) with complex surface structures, that make th ...

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, Mauro Moglianetti, Marta Mameli, Kellen Michael Harkness

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 ...

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

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

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 ...
