Des voies d'évolution pour les matériaux utilisés dans le matériel roulant SNCF
MATEC Web of Conferences, 2013 La recherche de la performance a été, dès les débuts du chemin de fer, une forte motivation des techniciens et ingénieurs. Si les premiers matériels étaient essentiellement en bois, l'introduction de matériaux métalliques dans les structures a permis des

Non destructive investigation of defects in composite structures by fullfield measurement methods [PDF]
, 2013 This paper presents different interests of non destructive full-field measurement. More precisely, it focuses on the characterization and the comparison of the X-ray tomography and two methods of infrared thermography in order to define the defect ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Laser-assisted guiding of electric discharges around objects [PDF]
, 2015 Electric breakdown in air occurs for electric fields exceeding 34 kV/cm and results in a large current surge that propagates along unpredictable trajectories.

Macromolecular Materials and Engineering, EarlyView.Hybrid networks combining natural and synthetic polymers into one network may result in networks with good bioactivity, suitable mechanical properties, and high control over degradation. This study shows that phase‐separated networks are obtained with the collagen phase acting as multifunctional crosslinks.

Overview of the theoretical relations between necking and strain localization criteria. [PDF]
, 2013 Many criteria have been developed during last decades to predict diffuse or localized necking and shear banding. The lack of confrontation of these models with each other on relevant applications makes their choice difficult for the designer.

From Molecule to Material: How Support Changes Heterobimetallic Catalysts in Lactide Polymerization
Macromolecular Rapid Communications, EarlyView.Silica‐supported heterobimetallic alkoxide complexes were developed as catalysts for lactide ring‐opening polymerization. Grafting iron‐based ate complexes onto SiO2‐700 produced well‐defined active sites, enabling controlled polymerization with predictable molar masses, narrow dispersities, and recyclability.
