Metal Distribution and Characterization of Cultivable Lead-Resistant Bacteria in Shooting Range Soils

Shooting ranges represent about 10% of polluted sites in Switzerland. This pollution, mainly consisting of lead (Pb) and antimony (Sb), can spread into the local groundwater, wildlife and plants. In this study, shooting range stop butt soils (elevated soil ...

Improving Heterogeneous Catalyst Stability for Liquid-phase Biomass Conversion and Reforming

Jeremy Luterbacher, Florent Emmanuel Héroguel, Bartosz Rozmyslowicz

Biomass is a possible renewable alternative to fossil carbon sources. Today, many bio-resources can be converted to direct substitutes or suitable alternatives to fossil-based fuels and chemicals. However, catalyst deactivation under the harsh, often liqui ...

Evaluation of Protective Coatings for SOFC Interconnects

Jan Van Herle, Michele Bianco

Chromium poisoning is a widely recognized degradation process in solid oxide fuel cells (SOFC). Stainless steel interconnect plates, in direct contact with the cathode, have been identified as the major chromium source, raising a need for electrically cond ...

Visualizing phosphodiester-bond hydrolysis by an endonuclease

The enzymatic hydrolysis of DNA phosphodiester bonds has been widely studied, but the chemical reaction has not yet been observed. Here we follow the generation of a DNA double-strand break (DSB) by the Desulfurococcus mobilis homing endonuclease I-DmoI, t ...

A general mechanism for intracellular toxicity of metal-containing nanoparticles

Francesco Stellacci, Randy Patrick Carney

The assessment of the risks exerted by nanoparticles is a key challenge for academic, industrial, and regulatory communities worldwide. Experimental evidence points towards significant toxicity for a range of nanoparticles both in vitro and in vivo. Worldw ...

The role of nanominerals and mineral nanoparticles in the transport of toxic trace metals: Field-flow fractionation and analytical TEM analyses after nanoparticle isolation and density separation

Nanominerals and mineral nanoparticles from a mining-contaminated river system were examined to determine their potential to co-transport toxic trace metals. A recent large-scale dam removal project on the Clark Fork River in western Montana (USA) has rele ...

Inertisation of heavy metals in municipal solid waste incineration fly ash by means of colloidal silica – a synchrotron X-ray diffraction and absorption study

Rudolf Paul Wilhelm Jozef Struis

Many efforts have been undertaken in past decades to minimize pollution from municipal solid waste incineration fly ash (MSWI FA). This residue is toxic, because of its high concentration of heavy metals, mainly Pb and Zn. A new method for heavy metals ent ...

Assessing metal bioaccumulation from estuarine sediments: comparative experimental results for the polychaete Arenicola marina

The purpose of this paper is to compare three approaches for providing information on the bioaccumulation potential of metals from contaminated sediments to the deposit-feeding polychaete Arenicola marina. We present metal (Ag, As, Cd, Cu, Pb and Zn) bioac ...
