Electrochemical Co-Deposition of Gold and Carbon Nanocapsules from a Colloidal Suspension

Stefano Mischler

This paper shows the preparation of a gold suspension containing carbon nanocapsules and their co-deposition from the colloidal galvanic bath on a nickel electrode to obtain gold/nanocapsules composite coatings. The incorporation of the nanocapsules was co ...

Colloidal Size and Redox State of Uranium Species in the Porewater of a Pristine Mountain Wetland

Rizlan Bernier-Latmani, Barbora Bártová, Manon Frutschi, Gabrielle Dublet, Ashley Richards Brown, Giada Chantal Zünd

Uranium (U) speciation was investigated in anoxically preserved porewater samples of a natural mountain wetland in Gola di Lago, Ticino, Switzerland. U porewater concentrations ranged from less than 1 mu g/L to tens of mu g/L, challenging the available ana ...

Interplay of S and As in Mekong Delta sediments during redox oscillations

Rizlan Bernier-Latmani, Laurent Louis José Charlet

The cumulative effects of periodic redox cycling on the mobility of As, Fe, and S from alluvial sediment to groundwater were investigated in bioreactor experiments. Two particular sediments from the alluvial floodplain of the Mekong Delta River were invest ...

High-Resolution Data Sets Unravel the Effects of Sources and Meteorological Conditions on Nitrate and Its Gas-Particle Partitioning

Athanasios Nenes, Qianyu Zhao, Yan Feng

Nitrate is one of the most abundant inorganic water-soluble ions in fine particulate matter (PM2.5). However, the formation mechanism of nitrate in the ambient atmosphere, especially the impacts of its semivolatility and the various existing forms of nitro ...

Rheological behavior of colloidal suspension with long-range interactions

In this work, we study the constitutive behavior of interacting colloidal suspensions for moderate and high concentrations. Specifically, using a lattice Boltzmann solver, we numerically examine suspensions flowing through narrow channels, and explore the ...

Contributions to 3D differential microwave imaging

Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

This paper presents new contributions to forward and inverse problems in 3D differential microwave imaging. This technique is well suited to monitor a pathological evolution, for instance the brain stroke of a patient. The forward problem is solved using a ...

Dendrimer-Stabilized Titanate Nanowire Dispersions as Potential Nanocarriers

László Forró, Endre Horvath, Marko Pavlovic

The effect of poly(amido amine) (PAMAM) dendrimers of generations G2, G6, and G10 on the dispersion stability of titanate nanowires (TiONWs) as potential nanocarriers was clarified in order to develop biocompatible delivery systems. The PAMAMs adsorbed str ...
