Fabrication of 2D gold nanowires by self-assembly of gold nanoparticles on water surfaces in the presence of surfactants
Tue Hassenkam,Kasper Nørgaard,Lars Iversen,Christopher J. Kiely,Mathias Brust,Thomas Bjørnholm +5 more
TL;DR: In this article, self-assembly of metallic nanostructures using 2D templates consisting of surfactant systems at the air/water interface is demonstrated, where the morphology of the resulting nanostructure can be partially controlled by adjusting parameters such as the molecular structure of the surfactants, the chemical properties of the assembly units, and the surface pressure.

Direct observation of oxygen configuration on individual graphene oxide sheets
Zilong Liu,Kasper Nørgaard,Marc H. Overgaard,Marcel Ceccato,David M. A. Mackenzie,Nicolas Stenger,Susan L. S. Stipp,Tue Hassenkam +7 more
TL;DR: In this article, the authors used a label free spectroscopic technique to map oxygen bonding on GO, with spatial resolution of nanometres and high chemical specificity, and proposed an updated structural model with C O on its edge and plane.

Solution‐Processed Ultrathin Chemically Derived Graphene Films as Soft Top Contacts for Solid‐State Molecular Electronic Junctions
Tao Li,Jonas Rahlf Hauptmann,Zhongming Wei,Søren Petersen,Nicolas Bovet,Tom Vosch,Jesper Nygård,Wenping Hu,Yunqi Liu,Thomas Bjørnholm,Kasper Nørgaard,Bo W. Laursen +11 more
TL;DR: A novel method using solution-processed ultrathin chemically derived graphene films as soft top contacts for the non-destructive fabrication of molecular junctions is demonstrated and it is believed this protocol will greatly enrich the solid-state test beds for molecular electronics due to its low-cost, easy-processing and flexible nature.

Langmuir−Blodgett Films of Alkane Chalcogenide (S,Se,Te) Stabilized Gold Nanoparticles
Mathias Brust,Nicolai Stuhr-Hansen,Kasper Nørgaard,Jørn B. Christensen,Lars K. Nielsen,Thomas Bjørnholm +5 more
TL;DR: In this article, the authors used the Langmuir films of thiolate and selenide-stabilized gold nanoparticles to obtain a core diameter of 2 nm and the stability of the particles under ambient conditions increased in the order Te < Se < S.

Graphene Oxide: A One- versus Two-Component Material.
Anton V. Naumov,Fabian Grote,Marc H. Overgaard,Alexandra Roth,Christian E. Halbig,Kasper Nørgaard,Dirk M. Guldi,Siegfried Eigler,Siegfried Eigler +8 more
TL;DR: Analysis of absorption and emission spectra as well as lifetime measurements reveal that properties of the combined system are distinctly different from those of GO, confirming structural models of GO as a separate oxygenated hexagonal carbon framework with optical properties governed by its internal structure rather than the presence of OD.
