Los Alamos National Laboratory W76 Pit Tube Lifetime Study

USDOE National Nuclear Security Administration (NNSA)、Terri Abeln2012-04-03OpenAlex

A metallurgical study was requested as part of the Los Alamos National Laboratory (LANL) W76-1 life-extension program (LEP) involving a lifetime analysis of type 304 stainless steel pit tubes subject to repeat bending loads during assembly and disassembly operations at BWXT/Pantex. This initial test phase was complete…

Elaboration de vitrocéramiques piézoélectriques texturées : Influence des caractéristiques des verres sur la cinétique de cristallisation et la microstructure

N. Maury、Maurice Gonon、F. Cambier2012-04-03ORBi UMONS

Actuellement, les matériaux piézoélectriques les plus couramment rencontrés sont des céramiques polycristallines ferroélectriques (essentiellement de type perovskite). L'inconvénient majeur de ces matériaux est le risque de dépolarisation, d'une part dans le temps et d'autre part, avec la température puisque au-delà d…

Etude acoustique de matériaux céramique poreux : structure isotrope et anisotrope

Dominique Hautcoeur、A Leriche、Maurice Gonon 等 5 位作者2012-04-03ORBi UMONS

Les méthodes traditionnelles de synthèse de matériaux céramiques poreux (méthode sacrificielle, moussage direct,...) conduisent à l'obtention de matériaux macroscopiquement isotropes. Cependant, la possibilité de produire des matériaux à porosité fortement orientée présente un fort intérêt par l'anisotropie des propri…

Landau-Ginzburg theory for the nematic superconductor state

Rafael de Vasconcellos Clarim2012-04-03LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

O objetivo geral deste projeto é propor um modelo bidimensional que descreva o novo estado supercondutor, que apresenta simetria de cristal líquido, chamado de supercondutor nemático. O estudo começa com uma introdução sobre a teoria de Landau-Ginzburg das transições de fase, onde são discutidos conceitos como parâmet…

The magnetic anisotropy induced by oxidation and thermal annealing : From structure to magnetism

H. Garad2012-04-03theses.fr (ABES)

Dans le domaine des couches minces (épaisseur~Å) associant un métal magnétique (Fe, Co, Ni) et un élément non magnétique (essentiellement métallique ou isolant), de remarquables propriétés physiques (aimantation, transport) nécessitent des caractérisations structurales fines. En particulier, citons le cas de jonctions…

Caractérisation des interactions entre mobile et milieu absorbant pour la dosimétrie non-invasive

Aycine Bellaouel、Azeddine Gati、David Lautru 等 5 位作者2012-04-03HAL (Le Centre pour la Communication Scientifique Directe)

Ce papier porte sur les méthodes de caractérisation des téléphones mobiles près de la tête. Le but est d'élaborer des méthodes non-invasives pour la dosimétrie de l'exposition. Pour cela, ce papier présente l'influence de la distance entre un mobile et un fantôme représentant une tête humaine sur la puissance rayonnée…

Considerations for contractile electroactive materials and actuators

Lenore Rasmussen、L. Meixler、Charles Gentile2012-04-03Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE

Electroactive polymers (EAPs) that bend, swell, ripple (first generation materials), and now contract with low electric input (new development) have been produced. The mechanism of contraction is not well understood. Radionuclide-labeled experiments, molecular modeling, electrolyte experiments, pH experiments, and an…

Kinetic resolution of racemates under chiral catalysis: connecting the dots

Sosale Chandrasekhar、Sosale Chandrasekhar2012-04-03Nature Precedings

The current theory of the titled phenomenon is apparently based on an inconsistent use of concentration units, as employed in the derivation of the fundamental equations. Thus, manifestly, whilst the relation between extent of conversion and e.e. is derived with mole fractions, the succeeding kinetic equations employ…
