Shape retaining self-healing metal-coordinated hydrogels

Esther Amstad, Alvaro Lino Boris Charlet, Raffaele Mezzenga

Metal-coordinated hydrogels are physical hydrogels entirely crosslinked by complexes between ligand decorated polymers and metal ions. The mechanical properties of these hydrogels strongly depend on the density and dynamics of metal-coordinated interaction ...

Stainless steel-like FeCrNi nanostructures via electrodeposition into AAO templates using a mixed-solvent Cr(III)-based electrolyte

Enrico Bertero

Electrodeposition of stainless steel-like materials such as FeCrNi alloy into micro- and nanotemplates provides a sustainable framework for creating biomedical-oriented micro- and nanocomponents with outstanding characteristics. While Cr(III)-based electro ...

In Situ Biostimulation of Cr(VI) Reduction in a Fast-Flowing Oxic Aquifer

Rizlan Bernier-Latmani, Daniel Scott Alessi

Hexavalent chromium is among the most common and hazardous inorganic contaminants in soils and groundwater. A promising in situ bioremediation approach is the delivery of electron donors to stimulate microbially mediated Cr(VI) reduction, producing relativ ...

'Green' Cr(iii)-glycine electrolyte for the production of FeCrNi coatings: electrodeposition mechanisms and role of by-products in terms of coating composition and microstructure

Stefano Mischler, Johann Michler, Enrico Bertero

The electrodeposition of stainless steel-like FeCrNi alloys for miniaturised devices is appealing as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, biocompatibility) at low-cost. However, conventional baths oft ...

Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments

Rizlan Bernier-Latmani, Imrich Barak, Zuzana Chromiková

Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...

Chromate Resistance Mechanisms in Leucobacter chromiiresistens

Rizlan Bernier-Latmani, Elena Suvorova Buffat

Chromate is one of the major anthropogenic contaminants on Earth. Leucobacter chromiiresistens is a highly chromate-resistant strain, tolerating chromate concentrations in LB medium of up to 400 mM. In response to chromate stress, L. chromiiresistens forms ...

Fate of Cr(III) during ozonation of secondary municipal wastewater effluent

Urs von Gunten, Caroline Gachet Aquillon

In the present study, the fate of trivalent chromium (Cr(III)) during ozonation of ultrapurified water and wastewater effluent was investigated. In experiments conducted in phosphate buffered ultrapurified water, O3 alone in excess was inefficient to oxidi ...

Impact of Cable Twist Pitch on T-cs-Degradation and AC Loss in Nb3Sn Conductors for ITER Central Solenoids

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

The performance of tour Nb3Sn conductors for the ITER central solenoids was tested. The current sharing temperatures (T-cs) were measured over approximately 9000 electromagnetic cycles, including two or three thermal cycles between 4.2 K and room temperatu ...

Screen-printed electrochemical chromium (VI) sensing electrodes for effluent bioremediation monitoring

Thomas Maeder, Caroline Jacq

Simple, low-cost and acid-resistant carbon-based screen-printed electrodes (SPEs) addressed to detection of hexavalent chromium species, Cr(VI), in sulfuric acid at pH about 1, were prepared and characterized. Working and counter electrodes were prepared j ...

Cathode thickness-dependent tolerance to Cr-poisoning in solid oxide fuel cells

Christos Comninellis, Jan Van Herle, Aïcha Hessler-Wyser, Josef Andreas Schuler, Pietro Tanasini

This work aimed to set new guidelines for the quantification of Cr accumulation in solid oxide fuel cell cathodes after operation, and enabled to pinpoint a diffusion-controlled tolerance to Cr-poisoning for increased cathode thickness; the additional cath ...

Surface oxide in replicated microcellular aluminium and its influence on the plasticity size effect

Andreas Mortensen, Frédéric Diologent

The oxide film present along the interface between metal and pores in microcellular aluminium produced by replication depends on the leaching medium that is used to dissolve the NaCl preform: leaching in water produces a thick and irregular multilayered hy ...
