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.

Highly Conductive Semitransparent Graphene Circuits Screen-Printed from Water-Based Graphene Oxide Ink
Marc H. Overgaard,Martin Kühnel,Rasmus Hvidsten,Søren Petersen,Tom Vosch,Kasper Nørgaard,Bo W. Laursen +6 more
TL;DR: A scalable water-based graphene oxide ink is reported that can be screen-printed on flexible plastic substrates and subsequently reduced using a 1:1 mixture of trifluoroacetic acid and hydroiodic acid, thereby creating an electric circuit as discussed by the authors.

Soluble and immobilized graphene oxide activates complement system differently dependent on surface oxidation state.
TL;DR: GO solutions, at concentrations below complement activating threshold, did not induce IL-6 release from human blood leukocytes, and further dampened lipopolysaccharide-induced IL- 6 release in the whole blood, and the latter effect became more profound with GO's having higher oxygen content.

Pollution-Induced Community Tolerance (PICT) in coastal phytoplankton communities exposure to copper
Kim Gustavson,Søren Petersen,B.M. Pedersen,Frank Stuer-Lauridsen,Stig A. Schack Pedersen,Sten-Åke Wängberg +5 more
TL;DR: The studies indicate that the PICT methodology is sensitive enough to detect even minor effects of copper on phytoplankton communities, and effects from concentrations as low as 1 μg Cu l-1 in highly eutrophic coastal areas, where the bioavailability of copper is assumed to be low.

Direct Toxic Effects of TBT on Natural Enclosed Phytoplankton at Ambient TBT Concentrations of Coastal Waters
Søren Petersen,Kim Gustavson +1 more
TL;DR: In this article, no effect concentrations (NEC) for tri-butyl-tin (TBT) were found in phytoplankton in the lower pico molar (pM) range as indicated by increased TBT tolerance, changes in taxonomic composition, decreased primary production and in the chlorophyll a (chl. a) concentration.
