Structural disordering of de-alloyed Pt bimetallic nanocatalysts: the effect on oxygen reduction reaction activity and stability
Spanos, Ioannis; Dideriksen, Knud; Kirkensgaard, Jacob J. K.; Jelavic, Stanislav; Arenz, Matthias
Platinum bimetallic alloys are well-known for their ability to catalyze the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). PtxCo1−x colloidal nanoparticles were synthesized with varying initial Pt:Co ratios, but constant size to investigate how the initial metal composition affects their electrocatalytic performance. The results show that…
Self-assembly of designed coiled coil peptides studied by small-angle X-ray scattering and analytical ultracentrifugation
Malik, Leila; Nygaard, Jesper; Christensen, Niels J.; Streicher, Werner W.; Thulstrup, Peter W.; Arleth, Lise; Jensen, Knud J.
α-Helical coiled coil structures, which are noncovalently associated heptad repeat peptide sequences, are ubiquitous in nature. Similar amphipathic repeat sequences have also been found in helix-containing proteins and have played a central role in de novo design of proteins. In addition, they are promising tools for the construction of nanomaterials.…
Simultaneous Enhancement of Solar Cell Efficiency and Stability by Reducing the Side Chain Density on Fluorinated PCPDTQx Copolymers
Verstappen, Pieter; Kesters, Jurgen; D’Olieslaeger, Lien; Drijkoningen, Jeroen; Cardinaletti, Ilaria; Vangerven, Tim; Bruijnaers, Bardo J.; Willems, Robin EM; D’Haen, Jan; Manca, Jean V.; others
The performance of polymer solar cells is strongly dependent on the morphology of the photoactive layer, which can be optimized by tuning the polymer side chain pattern. Whereas most studies focus on length and bulkiness, the side chain density receives much less attention. In this work, the effect of the…

Ion Distribution in Quaternary-Ammonium-Functionalized Aromatic Polymers: Effects on the Ionic Clustering and Conductivity of Anion-Exchange Membranes
Weiber, E. Annika; Jannasch, Patric
A series of copoly(arylene ether sulfone)s that have precisely two, three, or four quaternary ammonium (QA) groups clus- tered directly on single phenylene rings along the backbone are studied as anion-exchange membranes. The copolymers are synthesized by condensation polymerizations that involve either di-, tri-, or tetramethylhydroquinone followed by virtual- ly…
Highly proton conducting electrolyte membranes based on poly (arylene sulfone) s with tetrasulfonated segments
Weiber, E. Annika; Takamuku, Shogo; Jannasch, Patric
A series of fully aromatic polymers having only sulfone bridges linking the aromatic rings have been synthesized via polycondensations and studied as proton-exchange membranes. Mixtures of tetrasulfonated 4,4′-bis-1,1′-biphenyl (BCPSBP), non-sulfonated BCPSBP, and 4,4′-thiobisbenzenethiol were copolymerized by nucleophilic aromatic substitution reactions to obtain…
