Oxygen transport in La0.5Sr0.5Fe1−yTiyO3−δ (y=0.0, 0.2) membranes

Jan Van Herle, Stefan Diethelm, Defne Bayraktar

The influence of partial substitution of Fe with Ti on the oxygen transport properties of La1−xSrxFeO3 membranes was investigated in view of their application for oxygen separation. Samples of composition La0.5Sr0.5Fe1−yTiyO3−δ(y=0, 0.2) were prepared and ...

Influence of cationic and anionic additives on the electrical properties of ionophore-based ion-selective membranes

Nico de Rooij

The steady-state electrical behavior of cation-selective ionophore membranes with different kinds of ionic additives was studied on a theoretical basis. Membranes with both mobile and fixed anionic sites exhibit nonlinear current-voltage curves, which is i ...

Biomechanical properties of decellularized porcine common carotid arteries

Nikolaos Stergiopoulos, Sylvain Roy, Paolo Silacci

To analyze the effects of decellularization on the biomechanical properties of porcine common carotid arteries, decellularization was performed by a detergent-enzymatic procedure that preserves extracellular matrix scaffold. Internal diameter, external dia ...

Importin alpha associates with membranes and participates in nuclear envelope assembly in vitro

Importin alpha is well known as an adaptor that functions with Importin beta in the nuclear import of proteins containing specific nuclear localization signals (NLSs). We show here that either an excess or a lack of Importin alpha blocks nuclear envelope ( ...

Oxygen permeation and stability of La0.4Ca0.6Fe1 - xCoxO3-delta (x=0, 0.25, 0.5) membranes

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Peter Hugh Middleton

Three perovskite-type compounds of composition La0.4Ca0.6Fe1-xCoxO3-d (x=o, o.25 and 0.5) were investigated for use as oxygen separation membranes for the partial oxidation (POX) of methane to syngas. Special attention was given to the question of their st ...

Ligand Binding to G Protein-Coupled Receptors in Tethered Cell Membranes

Horst Vogel, Rudolf Hovius, Bruno Meyer

G protein-coupled receptors (GPCRs) constitute a large class of seven transmembrane proteins, which bind selectively agonists or antagonists with important consequences for cellular signaling and function. Comprehension of the mol. details of ligand bindin ...

Glycoprotein-associated amino acid exchangers: broadening the range of transport specificity

Lukas Kühn

Members of the newly discovered glycoprotein-associated amino acid transporter family (gpaAT-family) share a similar primary structure with >40% identity, a predicted 12-transmembrane segment topology and the requirement for association with a glycoprot ...

Incorporation of Rhodopsin in Laterally Structured Supported Membranes: Observation of Transducin Activation with Spatially and Time-Resolved Surface Plasmon Resonance

Horst Vogel, Klaus Peter Hofmann

Rhodopsin-transducin coupling was used as an assay to investigate a laterally patterned membrane reconstituted with a receptor and its G protein. It served as a model system to show the feasibility to immobilize G protein-coupled receptors on solid support ...
