Origine des microplastiques en eau douce

Microplastics in freshwater are becoming of emerging concerns. In Switzerland, some recent studies reveals the microplastics pollution of Swiss lakes and rivers. The aim of the present study is to improve the understanding of the origins of this pollution. ...

Probability of observable flaw initiation at high cycle fatigue

Vasileios Grigoriou

Fatigue evolution during the flaw initiation phase and under high cycle fatigue conditions is described at the level of the representative volume element by the probability that this element fails in a given period of time under given stimulus. This probab ...

Bidirectional Transfer Study of Polystyrene Nanoparticles across the Placental Barrier in an ex Vivo Human Placental Perfusion Model

Lionel André Maurizi

BACKGROUND: Nanoparticle exposure in utero might not be a major concern yet, but it could become more important with the increasing application of nanomaterials in consumer and medical products. Several epidemiologic and invitro studies have shown that nan ...

Pollution plastique dans les eaux suisses: caractérisation et quantification de leurs micropolluants

Colin Demars

Numerous researches showing various environmental impacts are done on marine plastic pollution. In turn the situation for superficial fresh water is poorly known. In order to measure this pollution in Switzerland three different lake samples (lake Geneva, ...

Fatigue Response of Solvent-Based Self-Healing Smart Materials

Véronique Michaud, Sam Neuser

We investigated the healing of epoxy resins with embedded ethyl phenylacetate (EPA) solvent loaded capsules and shape memory alloy (SMA) wires under fatigue loading in tapered double cantilever beam (TDCB) mode. Under cyclic loading, the kinetics of solven ...

An evaluation of surface micro and meso plastic pollution in pelagic ecosystems of western Mediterranean Sea

Luiz Felippe De Alencastro, Florian Faure, Pascal Hagmann

In the 90’s, the discovery of high concentrations of plastic debris in the oceans generated interest and concern of general public as well as scientific community. Since, the accumulation of plastic debris in the North Pacific and North Atlantic gyres has ...

Microstructure and deformation mechanisms in nanocrystalline Ni-Fe. Part II. In situ testing during X-ray diffraction

Helena Van Swygenhoven, Steven Van Petegem

Deformation mechanisms in nanocrystalline electrodeposited Ni (26 nm) and Ni-Fe (12 nm) are studied by strain rate sensitivity experiments and in situ mechanical testing during X-ray diffraction. We find a relatively low strength for Ni-Fe, which may be as ...

A microfluidic approach to synthesizing high-performance microfibers with tunable anhydrous proton conductivity

Philippe Renaud, Arnaud Bertsch, Mohammad Mahdi Hasani-Sadrabadi, Fatemeh Sadat Majedi, Jules John Vandersarl

Here, we demonstrate a new approach for the synthesis of ion exchange microfibers with finely tuned anhydrous conductivity. This work presents microfluidics as a system to control the size and phosphoric acid (PA) doping level of the polybenzimidazole (PBI ...
