Long-term biodegradation of crude oil in high-arctic backshore sediments: The Baffin Island Oil Spill (BIOS) after nearly four decades

With an on-going disproportional warming of the Arctic Ocean and the reduction of the sea ice cover, the risk of an accidental oil spill from ships or future oil exploration is increasing. It is hence important to know how crude oil weathers in this enviro ...

Natural slicks on Lake Geneva: From small-scale effects to large-scale formation and distribution

Mehrshad Foroughan

Low wind speeds (< 4 m/s) are ubiquitous in many water bodies, yet the physical processes occurring at the air-water interface in this range are poorly understood. A notable example is smooth patches on the water surface, known as natural slicks, formed wh ...

Monodisperse Selectively Permeable Hydrogel Capsules Made from Single Emulsion Drops

Esther Amstad, Alexandre Louis André Persat, Huachuan Du, Mathias Steinacher, Alice Cont

Capsules are often used to protect chemical and biological entities from the environment, to control the timing and location of their release, or to facilitate the collection of waste. Their performance depends on the thickness and composition of their she ...

A Closing Window of Opportunity to Save a Unique Marine Ecosystem

Anders Meibom, Maoz Fine

Five years in the making, a massive oil spill of 1 million barrels is imminent in the Red Sea off the coast of Yemen. Emergent action must be taken by the United Nations and its International Maritime Organization (IMO) to remove the oil, despite regional ...

Mitigation of impact of a major benzene spill into a river through flow control and in-situ activated carbon absorption

David Andrew Barry, Yue Yang

Benzene is a toxic contaminant and can harm many aquatic species and cause serious damages to the river eco-system, if released to rivers. In 2012, a major spill accident occurred on the Huaihe River in Eastern China with 3 tons of benzene released to the ...

Measurement of the muon flux from 400 GeV/c protons interacting in a thick molybdenum/tungsten target

Lesya Shchutska, Aurelio Bay, Guido Haefeli, Elena Graverini, Mikhail Chapochnikov, Alexey Boyarsky, Federico Leo Redi, Maria Elena Stramaglia, Inar Timiryasov, Alexandre Emmanuel Grandchamp

The SHiP experiment is proposed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. About 1011muons per spill will be produced in the dump. To design the experiment s ...

Cost and benefits of climate change in Switzerland

Philippe Thalmann, Marc Vielle, Frank Vöhringer, Boris Thurm, Dario Stocker, Wolfgang Knoke, Anita Frehner

Understanding the economic magnitude of climate change impacts is a prerequisite for developing adequate adaptation strategies. In Switzerland, despite new climate scenarios and impact studies, only few impacts have been monetized. Our objective is to asse ...

Microscale physico-chemical interactions between hydrodynamically confined liquids and immersed biological surfaces

David Philipp Taylor

In contrast to conventional microfluidics, where liquids are typically manipulated within closed channels, open-space microfluidics has emerged as a new class of techniques that are well suited for ver-satile interaction with biological substrates. In part ...

Hydration mediated interfacial transitions on mixed hydrophobic/hydrophilic nanodroplet interfaces

Sylvie Roke, Halil Ibrahim Okur, Nikolay Smolentsev, Rüdiger Scheu, Filip Kovacik

Interfacial phase transitions are of fundamental importance for climate, industry, and biological processes. In this work, we observe a hydration mediated surface transition in supercooled oil nanodroplets in aqueous solutions using second harmonic and sum ...

Comparison of methylisoborneol and geosmin abatement in surface water by conventional ozonation and an electro-peroxone process

Urs von Gunten, Gang Yu, Yan Wang, Chao Chen

In this study methylisoborneol (MIB) and geosmin abatement in a surface water by conventional ozonation and the electro-peroxone (E-peroxone) process was compared. Batch tests with addition of ozone (03) stock solutions and semi-batch tests with continuous ...
