Nonlinear saturation of resistive tearing modes in a cylindrical tokamak with and without solving the dynamics

We show that the saturation of resistive tearing modes in a cylindrical tokamak, as well as the corresponding island width, can be directly calculated with a magnetohydrodynamics (MHD) equilibrium code without solving the dynamics and without considering r ...

Probing Water Dissociation and Oxygen Replacement on Partially Oxygen-Covered Cu(111) by Reflection Absorption Infrared Spectroscopy

Rainer Beck, Mateusz Suchodol, Harmina Vejayan

The presence of chemisorbed oxygen on the Cu(111) surface is known to strongly reduce the activation barrier for water dissociation as compared to bare Cu(111). Here, we present direct experimental evidence for the hydrogen abstraction mechanism responsibl ...

Genomic consequences of colonisation, migration and genetic drift in barn owl insular populations of the eastern Mediterranean

Nicolas Jean Philippe Guex, Eléonore Lavanchy

The study of insular populations was key in the development of evolutionary theory. The successful colonisation of an island depends on the geographic context, and specific characteristics of the organism and the island, but also on stochastic processes. A ...

Assessing Subaquatic Mass Movement Hazards: an Integrated Observational and Hydrodynamic Modelling Approach

Damien Bouffard, Nathalie Dubois

High-resolution lake and reservoir bathymetric surveys can pinpoint locations that may experience underwater landslides (subaquatic sedimentary mass movements). These can pose a risk to underwater and shoreline infrastructure. This paper outlines an approa ...

Recycling Plastic and Marine Debris: What Can Be Done about Bottle Caps?

When will the weight of all fish in the ocean equal the weight of plastic discards in the ocean? These plastic discards in the water impacts birds and sea life around the world. Just as the canary in the coal mine forewarns of danger, the Laysan or Pacific ...

Rare Earth and Bimetallic Transition Metal Islands at Surfaces

Dimitrios Mousadakos

This thesis reports on the growth and on the magnetic characterization of nanostructures made of 3d-4d transition metals and rare earths. In all the experiments the nanostructures have been grown by atomic beam epitaxy (ABE) in ultra high vacuum conditions ...

Types and concentration of microplastics found on remote island beaches during the Race for Water Odyssey

Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca, Clément Levasseur

Initiated in 2015 by the Race for Water Foundation, the Race for Water Odyssey is an environmental expedition which sailed across Atlantic, Pacific & Indian Oceans. It has 3 main goals: i) analyse plastic pollution on beaches of remote islands; ii) raise a ...

Race For Water Odyssey: Quantitative and Qualitative Assessment of Marine Plastic Debris Collected on Shorelines

Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca, Clément Levasseur

With the help of the local people we met during the course of the 2015 Odyssey, the main objective, obtaining a collection of comparable data about marine plastic pollution using the NOAA internationally recognized protocol, has been achieved. It cannot be ...

Response of the topological surface state to surface disorder in TlBiSe2

Jan Hugo Dil, Stefan Peter Muff

Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile Tl atoms at room temperature. No ...

Self-organized ordered silver nanoparticle arrays obtained by solid state dewetting

Fabien Sorin, Arthur Le Bris

Spontaneous dewetting of a silver layer on a templated silica substrate is proposed as a promising low-cost process to produce self-organized metallic nanostructures. Periodic gratings with inverted pyramid pattern and periods ranging from 200 to 1000 nm a ...
