Designing laminated metal composites for tensile ductility

Andreas Mortensen, Amaël Maximilien Cohades, Arda Cetin

This contribution draws practical implications of a recently published estimation of the tensile ductility in laminated composites made of two ductile materials, typically metals or alloys, which harden as both the strain and the strain-rate increase. To t ...

Predicting Input Impedance and Efficiency of Graphene Reconfigurable Dipoles Using a Simple Circuit Model

Julien Perruisseau-Carrier, Michele Tamagnone

An analytical circuit model able to predict the input impedance of reconfigurable graphene plasmonic dipoles is presented. A suitable definition of plasmonic characteristic impedance, employing natural currents, is used to for consistent modeling of the an ...

Superconductivity-Induced Transparency in Terahertz Metamaterials

Odeta Limaj

A plasmonic analogue of electromagnetically induced transparancy is activated and tuned in the terahertz (THz) range in asymmetric metamaterials fabricated from high critical temperature (T-c) superconductor thin films. The asymmetric design provides a nea ...

Effect of a nm-sized interlayer on the Thermal Boundary Conductance between metals and diamond

Christian Monachon

Study the influence of adjunction of a dielectric or metallic interlayer on the Thermal Boundary Conductance (TBC) measurable between a metallic layer and a diamond substrate. An interlayer does not need to be thick to have a substantial influence influenc ...

Statistical distributions of trace metal concentrations in the northwestern Mediterranean atmospheric aerosol

Thomas Robin

The concentrations of 11 crustal and anthropogenic trace metals (Li, Al, V, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb) were measured from 2006 to 2008 in the atmospheric aerosol at a northwestern Mediterranean coast (station of Cap Ferrat, situated on the southeaster ...

Surface Plasmons on Graphene Sheets: Effect of Spatial Dispersion and Magnetostatic Bias

Juan Ramon Mosig, Julien Perruisseau-Carrier

We study the characteristics of surface plasmons propagating along graphene sheets, focusing on the effect of spatial dispersion and applied magnetostatic bias, and taking into account the influence of the surrounding media, applied electrostatic biasing f ...

Fano resonant plasmonic systems: Functioning principles and applications

Olivier Martin, Andrea Lovera, Benjamin Gallinet, Thomas Gerd Siegfried

Using a generalization of Fano formula that includes the intrinsic losses associated with metals, we retrieve the underlying modal structure that produces Fano resonances from the interference between a bright and a dark mode. This knowledge is used to det ...

Comparative evaluation of particle properties, formation of reactive oxygen species and genotoxic potential of tungsten carbide based nanoparticles in vitro

Kristin Schirmer

Tungsten carbide (WC) and cobalt (Co) are constituents of hard metals and are used for the production of extremely hard tools. Previous studies have identified greater cytotoxic potential of WC-based nanopartides if particles contained Co. The aim of this ...

Determination of trace metals accumulated and internalized by marine phytoplankton; interferences with colloidal organic matter

In the present work, we study the effects that aggregation of humic acids in seawater, and its adsorption to surfaces, can have on the determination of Cu and Pb accumulation by phytoplankton within the context of metal bioavailability studies, using the d ...

Propagation of hybrid TM-TE surface plasmons on magnetically-biased graphene sheets

Julien Perruisseau-Carrier

The propagation of plasmons on magnetically biased graphene sheets is addressed. The analysis is based on the transverse resonance method extended to handle the graphene conductivity tensor and allows easily accounting for substrate effects. A transcendent ...
