Development of a microfluidics biosensor for agarose-bead immobilized Escherichia coli bioreporter cells for arsenite detection in aqueous samples
Philippe Renaud, Harald Van Lintel, Nina Buffi
Contamination with arsenic is a recurring problem in both industrialized and developing countries. Drinking water supplies for large populations can have concentrations much higher than the permissible levels (for most European countries and the United Sta ...
2011Spectroscopic Studies on Iron-Chalcogenide Superconductors
Superconductivity in F-doped LaFeAsO, Tc= 26 K was first reported by Kamihara et al in 2008. Following that, more iron-based superconductors, e.g., (Ba,K)Fe2As2, LiFeAs, and Fe1+yTe1-xSex were discovered. The new class of high Tc superconductors have attra ...
EPFL2011Valence band structure of the Si(331)-(12 × 1) surface reconstruction
Corsin Battaglia, Philipp Aebi
Using angle-resolved photoelectron spectroscopy we investigate the electronic valence band structure of the Si(331)-(12 × 1) surface reconstruction for which we recently proposed a structural model containing silicon pentamers as elementary structural buil ...
2011LPCVD ZnO-based intermediate reflector for micromorph tandem solar cells
Christophe Ballif, Matthieu Despeisse, Sylvain Nicolay, Grégory Bugnon, Laura Ding, Thomas Söderström
The use of zinc oxide (ZnO) based intermediate reflector (ZIR) in micromorph solar cells using low pressure chemical vapor deposition (LPCVD) was investigated. The influences of deposition temperature and dopant gas concentration on grain size and lateral ...
2011Localized Ion Implantation Through Micro/Nanostencil Masks
Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Cristina Martin Olmos, Philippe Langlet, Oscar Vazquez Mena
A method is presented that allows the definition of micrometer- and submicrometer-sized implanted structures in silicon without using photoresist patterning. The process is based on the use of stencils as masks in a conventional ion implanter, and is tested ...
Institute of Electrical and Electronics Engineers2011Development of a bacterial biosensor for arsenite detection
In order to provide an alternative measurement tool for arsenic contamination, we are developing a sensor that uses agarose beads containing a genetically engineered Escherichia coli strain producing a fluorescent signal in response to arsenite. Beads with ...
2010Synthesis of Nanosized Mn-Doped ZnO by Low Temperature Decomposition of Hydrozincite Precursors
László Forró, Arnaud Magrez, Duncan Thomas Lindsay Alexander, Andrzej Sienkiewicz, Marijana Mionic Ebersold, Zlatko Mickovic
Transition-metal-doped ZnO is considered a promising candidate for applications in spintronics. Here, we developed it novel and versatile synthetic route for obtaining impurity-free Mn-doped zinc oxide (Zn1-xMnxO) materials witha well-controlled content of ...
2010Biochip with E. coli bacteria for detection of arsenic in drinking water
Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Jan Roelof van der Meer, Joël Theytaz
Arsenic and other pollutants are often present in trace amounts in drinking water in a number of countries. In aqueous solutions the sensitivity of arsenic- responsive bacterial bioreporters is far better than the performance of chemical field test kits. H ...

2009The biouptake and toxicity of arsenic species on the green microalga Chlorella salina in seawater
The present study focuses on the biouptake, biotransformations, and toxicity of arsenic species on the marine green alga Chlorella salina in seawater from the Bulgarian Black Sea coast. Exposure to equal concentrations of As(III) or As(V) led to equivalent ...
