Quantum dots coordinated with conjugated organic ligands: new nanomaterials with novel photophysics

open access: yesNanoscale Research Letters, 2007
CdSe quantum dots functionalized with oligo-(phenylene vinylene) (OPV) ligands (CdSe-OPV nanostructures) represent a new class of composite nanomaterials with significantly modified photophysics relative to bulk blends or isolated components.

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

open access: yesAdvanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

UPS spectra of lithium doped carbon nanostructures: quantum-chemical simulations

open access: yes, 2005
We present a quantum chemical study on the effect of lithium doping in hydrogen rich carbon nanostructures. To model the hydrogen rich carbon nanostructure we selected hexa-peri-hexabenzocoronene, a wellknown polycyclic aromatic hydrocarbon whose UPS ...
