Iron minerals within specific microfossil morphospecies of the 1.88 Ga Gunflint Formation

Kevin Lepot, Ahmed Addad, Andrew H. Knoll, Jian Wang, David Troadec, Armand Béché, Emmanuelle J. Javaux

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities...

Ambipolar spin diffusion in p-type GaAs: A case where spin diffuses more than charge

Fabian Cadiz, V. Notot, J. Filipovic, D. Paget, C. Weber, L. Martinelli, A. Rowe, S. Arscott

We investigate the diffusion of charge and spin at 15 K in p-type GaAs, combining transient-grating and energy-resolved microluminescence measurements to cover a broad range of photoelectron density. At very low optical power, in a unipolar nondegenerate regime, charge and spin diffuse at the same...

Passive UHF RFID system evaluation in a retail environment

Hadi Farhat, Plamen Iliev, Philippe Mariage, Nathalie Rolland

The work in this paper presents the study of the influence of a particular environment on the performances of passive UHF RFID tags attached to products presented in a retail store. The effects of the near-field environment and of the far field environment are successively and separately...

Non destructive evaluation of bi-material structures: a case study

Lynda Chehami, Nico F. Declercq, Paul Lohmuller, Pascal Pomarede, Boris Pitrowski, Fodil Meraghni, Esam Ahmed Mohamed, Othmane Ez-Zahraouy

Due to their specific elastic properties (high stiffness to mass ratio), regular microstructure materials (architectural materials), are widely used in industry. This work deals with nondestructive evaluation of a 3D bi-material structure made of an architectural ABS polymer embedded in an Epoxy...

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling...

An ultra broadband 0.5-18 GHz BPSK modulator

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5 - 18 GHz frequency bandwidth. Experimental results...

Advancements on the molecular design of nanoantibiotics: current level of development and future challenges

Roxana Jijie, Alexandre Barras, Florina Teodorescu, Rabah Boukherroub, Sabine Szunerits

Numerous antimicrobial drugs have been developed and commercialized to kill and inhibit the growth of pathogenic microbes. The therapeutic efficiency of these drugs has however become often inadequate for the treatment of microbial infections, the reasons being multiple. Oral administration results...

A comprehensive study of magnetic exchanges in the layered oxychalcogenides Sr3Fe2O5Cu2Q2 (Q = S, Se)

Minfeng Lü, Olivier Mentre, Elijah E. Gordon, Myung-Hwan Whangbo, Alain Wattiaux, Mathieu Duttine, Nicolas Tiercelin, Houria Kabbour

The layered oxysulfide Sr3Fe2O5Cu2S2 was prepared, and its crystal structure and magnetic properties were characterized by synchrotron X-ray diffraction (XRD), powder neutron diffraction (PND), Mössbauer spectroscopy measurements and by density functional theory (DFT) calculations. In addition, the...
