Phosphorous doping and drawing effects on the Raman spectroscopic properties of O=P bond in silica-based fiber and preform.

2012

International audience; We report an experimental study of the doping and drawing effects on the Raman activities of phosphorus (P)-doped silica-based optical fiber and its related preform. Our data reveal a high sensitivity level in the full width at half maximum value of the 1330 cm−1 (O = P) Raman band to the P-doping level. Its increase with the P doping level does not clash with an increase in the disorder of the O = P surrendering matrix. In addition, we observe that in the central core region of the sample (higher doping level), the drawing process decreases the relative band amplitude. We tentatively suggest that this phenomenon is due to the change in the first derivate of the bond…

Comparative theoretical study of the Ag–MgO (100) and (110) interfaces

1999

We have calculated the atomic and electronic structures of Ag–MgO(100) and (110) interfaces using a periodic (slab) model and an ab initio Hartree–Fock approach with a posteriori electron correlation corrections. The electronic structure information includes interatomic bond populations, effective charges, and multipole moments of ions. This information is analyzed in conjunction with the interface binding energy and the equilibrium distances for both interfaces for various coverages. There are significant differences between partly covered surfaces and surfaces with several layers of metal, and these can be understood in terms of electrostatics and the electron density changes. For complet…

Actions différentielles de xéno-hormones alimentaires sur les organes reproducteurs, le foie et le tissu adipeux chez le rat femelle : aspects endocr…

2007

Differential actions of dietary xenohormones on the reproductive organs, the liver and the adipose tissue in the female rat : endocrine, metabolic and morphogenetic aspects regarding the carcinogenic process. Over the past décades, the incidence of hormone-dependent cancers has dramatically increased in Western countries as compared to Asian countries. Environmental and dietary compounds able to mimic and interfère with endogenous hormones, especially reproductive ones, may be involved and among these xenohormones. xenoestrogens (XE) are particularly pointed at. The objective of this thesis was to détermine the conséquences of chronic dietary exposure to phytoestrogens and chemical xenoestr…
