pH matters: The influence of the catalyst ink on the oxygen reduction activity determined in thin film rotating disk electrode measurements
Inaba, Masanori; Quinson, Jonathan; Arenz, Matthias
We investigated the influence of the ink properties of proton exchange membrane fuel cell (PEMFC) catalysts on the oxygen reduction reaction (ORR) activity determined in thin film rotating disk electrode (TF-RDE) measurements. It was found that the adaption of a previously reported ink recipe to home-made catalysts does not lead…
POSS Moieties with PEG Vertex Groups as Diluent in Polyurethane Elastomers: Morphology and Phase Separation
Koutsoumpis, Stefanos; Raftopoulos, Konstantinos N.; Jancia, Małgorzata; Pagacz, Joanna; Hebda, Edyta; Papadakis, Christine M.; Pielichowski, Krzysztof; Pissis, Polycarpos
Polyhedral oligomeric silsesquioxane moieties with poly(ethylene glycol) groups attached on the cage (PEG–POSS) were blended with an elastomeric polyurethane matrix, in contents up to 10 wt %. Several experimental techniques in agreement with each other show that the PEG–POSS moieties disperse well on the molecular level and act as diluents…

Effect of cholesterol on the molecular structure and transitions in a clinical-grade lung surfactant extract
Andersson, Jenny Marie; Grey, Carl; Larsson, Marcus; Ferreira, Tiago Mendes; Sparr, Emma
The lipid–protein film covering the interface of the lung alveolar in mammals is vital for proper lung function and its deficiency is related to a range of diseases. Here we present a molecular-level characterization of a clinical-grade porcine lung surfactant extract using a multitechnique approach consisting of H1H1
From evaporation-induced self-assembly to shear-induced alignment
Srikantharajah, R.; Schindler, T.; Landwehr, I.; Romeis, S.; Unruh, T.; Peukert, W.
The functionality of compact nanostructured thin films depends critically on the degree of order and hence on the underlying ordering mechanisms during film formation. For dip coating of rigid nanorods the counteracting mechanisms, evaporation-induced self-assembly (EISA) and shear-induced alignment (SIA) have recently been identified as competing ordering mechanisms. Here, we…
Strong Ligand–Block Copolymer Interactions for Incorporation of Relatively Large Nanoparticles in Ordered Composites
Gai, Yue; Lin, Ying; Song, Dong-Po; Yavitt, Benjamin M.; Watkins, James J.
For well-ordered block copolymer (BCP) nanocomposites containing nanoparticles (NPs), the ratio of NP core diameter (dcore) and BCP domain width (L) has been generally limited with dcore/L < 0.3 when NP/BCP interactions are relatively neutral or weak. Here, we systematically investigate the spatial distribution of gold nanoparticles (NP) ranging in…

Big Effect of Small Nanoparticles: A Shift in Paradigm for Polymer Nanocomposites
Cheng, Shiwang; Xie, Shi-Jie; Carrillo, Jan-Michael Y.; Carroll, Bobby; Martin, Halie; Cao, Peng-Fei; Dadmun, Mark D.; Sumpter, Bobby G.; Novikov, Vladimir N.; Schweizer, Kenneth S.; Sokolov, Alexei P.
Polymer nanocomposites (PNCs) are important materials that are widely used in many current technologies and potentially have broader applications in the future due to their excellent property tunability, light weight, and low cost. However, expanding the limits in property enhancement remains a fundamental scientific challenge. Here, we demonstrate that well-dispersed,…
