Quantitative chemical biosensing by bacterial chemotaxis in microfluidic chips
Harald Van Lintel, Jan Roelof van der Meer, Clémence Roggo
Whole-cell bacterial bioreporters are proposed asalternatives to chemical analysis of, for example, pol-lutants in environmental compartments. Commonlybased on reporter gene induction, bioreporters pro-duce a detectable signal within 30 min to a few hoursa ...
Wiley-Blackwell2018Evaluation of a full-scale wastewater treatment plant upgraded with ozonation and biological post-treatments: Abatement of micropollutants, formation of transformation products and oxidation by-products
Urs von Gunten, Hansruedi Siegrist
To protect the ecosystem and drinking water resources in Switzerland and in the countries of the downstream catchments, a new Swiss water protection act entered into force in 2016 aiming to reduce the discharge of micropollutants from wastewater treatment ...
2018Biporous Metal-Organic Framework with Tunable CO2/CH4 Separation Performance Facilitated by Intrinsic Flexibility
Berend Smit, Kyriakos Stylianou, Seyedmohamad Moosavi, Daniele Ongari, Peter George Boyd, Andrzej Gladysiak, Arunraj Chidambaram, Kathryn Suzanne Deeg, Kaili Yee Ordiz
In this work, we report the synthesis of SION-8, a novel metal-organic framework (MOF) based on Ca(II) and a tetracarboxylate ligand TBAPy(4-) endowed with two chemically distinct types of pores characterized by their hydrophobic and hydrophilic properties ...
2018Bacterial iron reduction and biogenic mineral formation for the stabilisation of corroded iron objects
Julien Maillard, Arnaud Michel Gelb
Exploiting bacterial metabolism for the stabilisation of corroded iron artefacts is a promising alternative to conventional conservation-restoration methods. Bacterial iron reduction coupled to biogenic mineral formation has been shown to promote the conve ...
2018Chelating agents as coating molecules for iron oxide nanoparticles
Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Marijana Mionic Ebersold, Débora Bonvin
Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...
RSC Publishing2017To what extend the dam dredging can influence the background level of metals in the Rhine River: using chemical and biological long-term monitoring to answer
Dredging generates remobilisation of sediments contaminated by non-degradable compounds such as metals, to which aquatic organisms can be exposed. This study aims at assessing the environmental impact of sediments remobilised in the Rhine River (France) du ...
Edp Sciences S A2017A Microfluidic Biodisplay
Sebastian Maerkl, Francesca Volpetti, Ekaterina Emilova Petrova
Synthetically engineered cells are powerful and potentially useful biosensors, but it remains problematic to deploy such systems due to practical difficulties and biosafety concerns. To overcome these hurdles, we developed a microfluidic device that serves ...
American Chemical Society2017On the bioavailability of trace metals in surface sediments: a combined geochemical and biological approach
The bioavailability of metals was estimated in three river sediments (Sens,e, Scarpe, and DeA >> le Rivers) impacted by different levels of Cu, Cd, Pb, and Zn (Northern France). For that, a combination of geochemistry and biological responses (bacteria and ...
Springer Heidelberg2016An automated microreactor for semi-continuous biosensor measurements
Philippe Renaud, Harald Van Lintel, Nina Buffi, Jan Roelof van der Meer
Living bacteria or yeast cells are frequently used as bioreporters for the detection of specific chemical analytes or conditions of sample toxicity. In particular, bacteria or yeast equipped with synthetic gene circuitry that allows the production of a rel ...
Royal Society of Chemistry2016Behaviour of composite sandwich decks at high temperatures
Structures made of FRP composites have been shown to provide efficient and economical applications in bridges and piers. They are being increasingly used due to their several advantages when compared to traditional materials, namely, the lightness, strengt ...
