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 ...

Phytoextraction of zinc, zinc oxide, copper and copper oxide in hydroponic solution with gibberellic acid and EDDS amendments by Lolium perenne

Flore Alice Margot Dupuich

This work was focused on the phytoextraction of zinc, copper, zinc oxide and copper oxide by Lolium perenne cultivated in hydroponic conditions, with gibberellic acid (GA) and ethylenediamine-N,N’-disuccinic acid (EDDS) amendments tested separately and in ...

Bioavailable copper modulates oxidative phosphorylation and growth of tumors

Johan Auwerx, Douglas Hanahan, Pénélope Andreux, Carole Poitry-Yamate, Seiko Ishida

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper ...

A new model for biomineralization and trace-element signatures of Foraminifera tests

Anders Meibom

The Mg/Ca ratio of Foraminifera calcium carbonate tests is used as proxy for seawater temperature and widely applied to reconstruct global paleo-climatic changes. However, the mechanisms involved in the carbonate biomineralization process are poorly unders ...

Radioactive Europium-Chelate-Based Silica Nanoparticles as a Probe for Stability, Incorporation Efficiency and Trace Analysis

Marinella Mazzanti

Two luminescent terbium and europium lanthanide chelates were efficiently embedded into silica nanoparticles by using a reverse microemulsion process. The incorporation was achieved without covalent bonding between the lanthanide chelates and the silica ma ...

Skeletal growth dynamics linked to trace-element composition in the scleractinian coral Pocillopora damicornis

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon, Christophe Kopp

The micro-and ultra-structural skeletal growth dynamics of the scleractinian coral Pocillopora damicornis (Linnaeus 1758) was studied with pulsed Sr-86-labeling and high spatial resolution NanoSIMS isotopic imaging. Average extension rates for the two basi ...

Development and Application of Devices for Online Trace Element Analysis of Thermal Process Gases from Woody Feedstocks

Marco Wellinger

When using natural or waste wood in thermo-chemical conversion processes, the presence of a number of heteroatoms (e.g. sulfur, chlorine, potassium and sodium or heavy metals) may hinder the processes themselves as well as pose a threat to equipment and/or ...

Utilization of Silicate Minerals for pH Control during In Situ Bioremediation of Chlorinated Solvents

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Background/Objectives. Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater due to their extensive use in industrial processes. In situ bioremediation (ISB) is an attractive techno ...

Simulation tool for variably saturated flow with comprehensive geochemical reactions in two and three-dimensional domains

David Andrew Barry, Laurin Wissmeier

We present a software tool for simulations of flow and multi-species solute transport in two and three-dimensional domains in combination with comprehensive intra-phase and inter-phase geochemistry. The software uses IPhreeqc, the coupling version of the g ...

Interfacial Energy Anisotropy and Growth Morphologies in Aluminium-Zinc Alloys

Jonathan Friedli

This thesis presents an investigation aimed at the understanding of the effect of interfacial energy anisotropy on growth morphologies in Al-Zn alloys. Most low alloyed metals form dendritic structures that grow along directions that correspond to low inde ...
