Scattering on plasmonic nanostructures arrays modeled with a surface integral formulation

Olivier Martin, Benjamin Gallinet

The surface integral formulation is a flexible, multiscale and accurate tool to simulate light scattering on nanostructures. Its generalization to periodic arrays is introduced in this paper. The general electromagnetic scattering problem is reduced to a d ...

Micrometeorological and morphological observations of surface hoar dynamics on a mountain snow cover

Michael Lehning, Charles Fierz

The formation, growth, and destruction of surface hoar crystals is an important feature of mountain snow covers as buried surface hoar layers are a frequent weak layer leading to unstable snowpacks. The energy and mass exchange associated with surface hoar ...

Image potential states as a quantum probe of graphene interfaces

Klaus Kern

Image potential states (IPSs) are electronic states localized in front of a surface in a potential well, formed by the surface projected bulk band gap on one side and the image potential barrier on the other. In the limit of a two-dimensional solid, a doub ...

Method for recovering silicon from sawing waste

Patrik Willi Hoffmann

A method for separating and recovering silicon debris from sawing waste is characterized in that it comprises the following steps: - treating the sawing waste so as to deoxidize the silicon debris in a manner that reduces their surface energy, - applying t ...

Magnetism of individual atoms adsorbed on surfaces

Harald Brune, Pietro Gambardella

Magnetic impurities in solids cause manifold changes in their macroscopic properties, such as anomalous low temperature resistance due to Kondo screening, reduction of the superconducting transition temperature due to local suppression of the order paramet ...

Tailoring band gaps of insulators by adsorption at surface defects: Benzoic acids on NaCl surfaces

Wei Chen

The adsorption of benzoic acid and its OH-substituted derivatives, namely, salicylic acid (SA) and parasalicylic acid on various NaCl surfaces has been investigated by density-functional theory with hybrid exchange-correlation functional. The ideal NaCl (1 ...

The covalent attachment of adhesion molecules to silicone membranes for cell stretching applications

Jean-Jacques Meister, Hicham Majd, Boris Hinz, Lara Buscemi Estefanell, Pierre Jean Arnould Wipff

Strain devices with expandable polydimethylsiloxane (PDMS) culture membranes are frequently used to stretch cells in vitro, mimicking mechanically dynamic tissue environments. To immobilize cell-adhesive molecules to the otherwise non-adhesive PDMS substra ...

The influence of surface tension gradients on drop coalescence

John Bush

We present the results of a combined experimental and numerical investigation of the coalescence of a drop with a liquid reservoir of a miscible but distinct fluid. Particular attention is given to elucidating the influence on the coalescence process of a ...
