Checking the Dark Matter Origin of a 3.53 keV Line with the Milky Way Center

We detect a line at 3.539 +/- 0.011 keV in the deep exposure data set of the Galactic center region, observed with the x-ray multi-mirror mission Newton. The dark matter interpretation of the signal observed in the Perseus galaxy cluster, the Andromeda gal ...

Coupling between high-frequency ultrasound and solar photo-Fenton at pilot scale for the treatment of organic contaminants: An initial approach

César Pulgarin, Stefanos Papoutsakis

This study aims to evaluate the performance of a novel pilot-scale coupled system consisting of a high frequency ultrasonic reactor (400 kHz) and a compound parabolic collector (CPC). The benefits of the concurrent application of ultrasound and the photo-F ...

Computational Design of Strain in Core-Shell Nanoparticles for Optimizing Catalytic Activity

William Curtin, Philip Arthur Moseley

Surface strains in core–shell nanoparticles modify catalytic activity. Here, a continuum-based strategy enables accurate surface-strain-based screening and design of core–shell systems using minimal input as a means to enhance catalytic activity. The appro ...

Observation of the cosmic-ray shadow of the Moon with IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on the observation of a significant deficit of cosmic rays from the direction of the Moon with the IceCube detector. The study of this "Moon shadow" is used to characterize the angular resolution and absolute pointing capabilities of the detector ...

Insertion of Nanoparticle Clusters into Vesicle Bilayers

Rudolf Hovius, Davide Demurtas, Alke Fink

A major contemporary concern in developing eective liposomeÀnanoparticle hybrids is the present inclusion size limitation of nanoparticles between vesicle bilayers, which is considered to be around 6.5 nm in diameter. In this article, we present experimen ...

Hollow cylinder simulation experiments of galleries in Boom Clay formation

Vincent Labiouse, Claire Sauthier, Shuang You

In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) induced by the construction of galleries in the Boom Clay formation. For this purpose, thick-wall ...

“With-me-ness”: A gaze-measure for students’ attention in MOOCs

Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma

We propose a gaze-based indicator of students’ attention in a MOOC video lecture. We report the results from an eye-tracking study during a MOOC lecture. We define the gaze- based indicator of students’ attention as “with-me-ness”. This answers a question ...

Slip Fronts at Frictional Interfaces

David Simon Kammer

Even though friction affects everyday life in many ways, it is still one of the biggest mysteries of physics. Friction is a truly multi-scale phenomenon with a large variety of processes acting at various length and time scales. In recent years, much atten ...

Control of groundwater pH during bioremediation: Improvement and validation of a geochemical model to assess the buffering potential of ground silicate minerals

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. The use of ground silicate minerals mixed with groundwater is an appealing buffering strategy as silicate minerals may act as long-term s ...
