Influence of oxide films on primary water stress corrosion cracking initiation of alloy 600 [PDF]

, 2006
In the present study alloy 600 was tested in simulated pressurised water reactor (PWR) primary water, at 360 °C, under an hydrogen partial pressure of 30 kPa. These testing conditions correspond to the maximum sensitivity of alloy 600 to crack initiation.

Ein Dithio‐Vinylthio‐C2‐Synthon, das kristalline und lumineszierende, schwefelhaltige Polymere ermöglicht

Angewandte Chemie, EarlyView.
Die Umsetzung von CaC2 zu einem modularen C2‐Baustein ermöglicht die Synthese eines α,ω‐Bis(vinylthio)‐Monomers sowie dessen Weiterumsetzung zu kristallinen, sequenzdefinierten, schwefelfunktionalisierten Polymere. Dichte Thioether‐Cluster induzieren nichtkonventionelle Lumineszenz und ermöglichen eine präzise Kontrolle der Struktur‐Eigenschafts ...

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

Exploiting the localized surface plasmon modes in gold triangular nanoparticles for sensing applications [PDF]

, 2012
In this study we investigate and exploit, for optical sensing, the surface plasmon excitation in gold triangular nanoparticles with high aspect ratios (i.e., the ratio of the edge length of the triangles with the height) prepared by nanosphere ...

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

Angewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.

Grain Boundaries in Graphene on SiC(000$\bar{1}$) Substrate

, 2014
Grain boundaries in epitaxial graphene on the SiC(000$\bar{1}$) substrate are studied using scanning tunneling microscopy and spectroscopy. All investigated small-angle grain boundaries show pronounced out-of-plane buckling induced by the strain fields ...

Effect of layer thickness on thermal properties of multilayer thin films produced by PVD [PDF]

, 2012
Cr/CrN/CrAlN, CrN/CrAlN and Cr/CrN thin layers were deposited by PVD (Physical Vapor Deposition). The multilayers were obtained from the combined deposition of different layers Cr, CrN and CrAlN thick films on on AISI4140 steel and silicon substrates at ...

Influence des paramètres matériaux sur le comportement des élastomères Influence of the material parameters on the mechanical properties of rubbers

MATEC Web of Conferences, 2013
Le comportement sous sollicitations cycliques des matériaux élastomères induit un adoucissement, une déformation rémanente et une anisotropie. Le travail présenté portera sur la caractérisation de ces phénomènes d'endommagements afin d'établir des liens ...
