Removal of pharmaceuticals from water: Using liquid-core microcapsules as a novel approach

In recent years ever-increasing amounts of pharmaceuticals are being detected in the aquatic environment and in some cases, they have even been discovered in drinking water. Their presence is attributed mainly to the inability of sewage treatment plants to ...

High resolution in situ magneto-optic Kerr effect and scanning tunneling microscopy setup with all optical components in UHV

Harald Brune, Stefano Rusponi, Philipp Buluschek, Nicolas Weiss, Anne Lehnert, Matthias Treier

A surface magneto-optic Kerr effect (MOKE) setup fully integrated in an ultrahigh vacuum chamber is presented. The system has been designed to combine in situ MOKE and scanning tunneling microscopy. Magnetic fields up to 0.3 T can be applied at any angle i ...

Algebraic turbulence modeling in adiabatic gas–liquid annular two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers algebraic turbulence modeling in adiabatic gas-liquid annular two-phase flow. After reviewing the existing literature, two new algebraic turbulence models are proposed for both the liquid film and the droplet laden gas core of annular t ...

Spin-Peierls instabilities of antiferromagnetic rings in a magnetic field

Frédéric Mila, Karlo Penc, Ioannis Rousochatzakis

Motivated by the intriguing properties of magnetic molecular wheels at field-induced level crossings, we investigate the spin-Peierls instability of antiferromagnetic rings in a field by exact diagonalizations of a microscopic spin model coupled to the lat ...

Mechanically tunable optofluidic distributed feedback dye laser

Demetri Psaltis

A continuously tunable optofluidic distributed feedback (DFB) dye laser was demonstrated on a monolithic replica molded poly(dimethylsiloxane) (PDMS) chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liqu ...

Rapid electron internal transport barrier formation during magnetic shear reversal in fully non-inductive TCV discharges

Olivier Sauter, Stefano Coda, Timothy Goodman, Antoine Pochelon, Yann Camenen, Emiliano Fable, Costanza Zucca, Petri Nikkola

The rapid formation of an electron internal transport barrier (eITB) is observed during a slow evolution (similar or equal to 200 ms) from a centrally peaked to a hollow current density profile, while all external actuators remain constant. The time consta ...

Rapid and localized electron internal-transport-barrier formation during shear inversion in fully noninductive TCV discharges

Olivier Sauter, Stefano Coda, Timothy Goodman, Antoine Pochelon, Yann Camenen, Petri Nikkola

Clear evidence is reported for the first time of a rapid localized reduction of core electron energy diffusivity during the formation of an electron internal-transport barrier. The transition occurs rapidly (similar or equal to3 ms), during a slow (similar ...

Osmium isotopic compositions of Os-rich platinum group element alloys from the Klamath and Siskiyou Mountains

Anders Meibom, Reto Frei

[1] We present new measurements of Os-186/Os-188 and Os-187/Os-188 in 10 Os-rich platinum group element (PGE) alloys from placer deposits formed by the mechanical erosion of peridotite-bearing ophiolites in the Klamath and Siskiyou Mountains in northern Ca ...

The Hadean upper mantle conundrum: Evidence for source depletion and enrichment from Sm-Nd, Re-Os, and Ph isotopic compositions in 3.71 Gy boninite-like metabasalts from the Isua Supracrustal Belt, Greenland

Anders Meibom, Reto Frei

Here we present Sm-Nd, Re-Os, and Pb isotopic data of carefully screened, least altered samples of boninite-like metabasalts from the Isua Supracrustal Belt (ISB, W Greenland)that characterize their mantle source at the time of their formation. The princip ...

Linear motor optimization using an analytical model

Yves Perriard, Marcel Jufer, Miroslav Markovic

This paper describes a linear motor optimization based on an analytical model. The studied motor, also called "ironless", consists of an iron core U shape with permanent magnets on each side, between which the coils can move. The glider which supports the ...
