Golden Opportunities: Gold Nanoparticles for Biomedical Applications
13 Jan 2020 | | Contributor(s):: Catherine J. Murphy
In this talk I will discuss how these nanoparticles are prepared, how their surface chemistry can be tuned, how apparent cytotoxicity can be traced back to reagents in the synthesis rather than the particles per se, how protein orientation can be controlled on their surfaces, how cells respond...

MCW07 Conductance Switching in Fluorene/TiO2 Molecular Heterojunctions
13 Sep 2007 | | Contributor(s):: Richard L.McCreery
Molecular junctions consisting of a monolayer of fluorene and 10 nm of TiO2 between conducting contacts exhibit a memory effect upon positive polarization of the of the TiO2 for a few milliseconds. The junction conductance increases for a period of several minutes, but can be “erased” by a...

MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach
05 Sep 2007 | | Contributor(s):: Jeffrey B. Neaton
Most recent theoretical studies of electron transport in single-molecule junctions rely on a Landauer approach, simplified to treat electron-electron interactions at a mean-field level within density functional theory (DFT). While this framework has proven relatively accurate for certain systems,...
