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.…

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…
