Nanophotonics—the science and technology of confining, guiding, making photons interact with matter at the nanoscale—is an active research field. By varying geometry constituent materials, nanostructures allow precise control scattering incident light tailoring emitted light. In this Tutorial, we outline use Maxwell equations to model optical response nanostructures. This electromagnetic optics...

Mounting evidence reveals that selenium is a dietary constituent with anticarcinogenic and antitumorigenic properties. Various forms of selenium appear to be effective in bringing about these effects, although preclinical studies suggest that differences may arise as the quantity provided is reduced. The literature also documents the greater sensitivity of neoplastic cells to selenium than thei...

RATIONALE Isotope ratio mass spectrometry (IRMS) is used extensively to reconstruct general attributes of prehistoric and modern diets in both humans and animals. In order to apply these methods to the accurate determination of specific intakes of foods/nutrients of interest, the isotopic signature of individually consumed foods must be constrained. For example, 86% of the calories consumed in ...

Thèse présentée pour l'obtention du grade légal de Docteur en Sciences Directeur de thèse : D r Claude Semay Membres du jury : Remerciements Bientôt 4 ans depuis mon arrivéè a l'université de Mons-Hainaut, la thèse se termine et une page se tourne. L'entrée dans l'univers de la recherche n'est pas une tâche aisée et cette aventure, loin d'ˆ etre terminée (je l'espère !), n'aurait pas commencé s...
