Improved stability of La0.5Sr0.5FeO3 by Ta-doping for oxygen separation membrane application

Jan Van Herle, Stefan Diethelm, Defne Bayraktar

(La,Sr)FeO3 mixed conducting perovskites are considered as interesting candidates for oxygen separation membranes but they suffer from limited structural stability in a large oxygen partial pressure (pO2) gradient, because of their propensity for chemical ...

Metal Ion Implantation for the Fabrication of Stretchable Electrodes on Elastomers

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on low-energy metal ion implantation by filtered cathodic vacuum arc to create highly deformable electrodes on polydimethylsiloxane (PDMS) membranes. Implantation leads to the creation of nanometer-size clusters in the first 50 nm below the surfa ...

Separation properties of supported ionic liquid-polydimethylsiloxane membrane in pervaporation process

Zhaofu Fei

Pervaporation separation properties of water-butan-l-of binary mixtures were measured with the use of three supported liquid membranes at 37 C, namely PDMS, 1-ethenyl-3-ethyl-imidazolium hexafluorophosphate-PDMS, and tetrapropyl-ammonium tetracyanoborate-P ...

In-situ determination of trace metal species in surface waters of Black Sea coastal area: comparison to bioavailability by green microalgae

Trace metal speciation in seawater from the Bulgarian Black Sea coast was studied in situ by hollow fiber permeation liquid membrane (HF-PLM) and by diffusion gradients in thin- film gels (DGT). The concentrations of Cd, Cu, Ni, and Pb determined by HF- ...

Single-molecule motions of oligoarginine transporter conjugates on the plasma membrane of Chinese hamster ovary cells

Hui Wang

To explore the real-time dynamic behavior of molecular transporters of the cell-penetrating-peptide (CPP) type on a biological membrane, single fluorescently labeled oligoarginine conjugates were imaged interacting with the plasma membrane of Chinese hamst ...

Towards a LED based on a photonic crystal nanocavity for single photon sources at telecom wavelength

Romuald Houdré, Laurent Balet, Nicolas Le Thomas, Blandine Alloing, Carl Zinoni

A fundamental step towards achieving an "on demand" single photon source would be the possibility of electrical pumping for a single QD and thus the integration of such a device in an opto-electronic circuit. In this work we describe the fabrication proces ...

In situ fabrication of a polyacrylamide membrane in a microfluidic channel

Martinus Gijs, Virendra Kumar Parashar, Jean-Baptiste Robert Orhan

We present a novel technological approach for the in situ realization of a micron-thin poly-acrylamide membrane in the center of a microfluidic channel. The membrane is formed by interfacial polymerization of an inner stream of monomer solution in between ...

Spontaneous $ Na ^{ + } $ Transients in Individual Mitochondria of Intact Astrocytes

Michaël Unser, Dimitri Nestor Alice Van De Ville, Jean-Yves Chatton

Mitochondria in intact cells maintain low

Na ^{ + }

levels despite the large electrochemical gradient favoring cation influx into the matrix. In addition, they display individual spontaneous transient depolarizations. We report here that individual mit ...

Recent knowledge and innovations related to hexofuranosides: structure, synthesis and applications

Ronan Euzen

Hexofuranosides are widely spread in nature, and notably in numerous pathogenic microorganisms. This particular five-membered ring for hexosides leads to novel biological properties and, as usual in glycochemistry, to completely different reactivity and se ...
