Abstract:

Sous irradiation, les flux de particules (neutrons, ions, électrons) créent des défauts ponctuels (lacunes et interstitiels) qui génèrent des défauts étendus (boucles de dislocation, cavités) responsables de la fragilisation des matériaux. L'aluminium est un matériau de faible masse et de faible énergie seuil de déplacement (Ed=16-19 eV) ce qui permet de créer les nanodéfauts étendus directement sous irradiation aux électrons dans un microscope électronique à transmission haute résolution (HRMET).

Aberration corrected transmission electron microscopy is a powerful tool for the structural characterisation of materials at the atomic scale, but the passage of high velocity electrons through the material can often induce structural changes via the transfer of large amounts of energy from the beam.

Chemical sanitizers have been extensively used in the industry for decontamination of fresh produce. However, they are ineffective in certain commodities and under certain processing conditions, necessitating the evaluation of alternative technologies. Electron beam irradiated sliced cantaloupe were tested for 21 days of storage for total aerobic bacterial counts, texture, color and sensory parameters as a function of irradiation doses 0, 0.7 and 1.4 kGy an

Abstract:

Carbon nanotubes (CNT) have extraordinary properties, such as exceptional strength, which are derived from their unique structure. However, the weak Van der Waals (VdW) interactions between adjacent CNTs produce bundled axial properties significantly lower than isolated nanotubes. The VdW interactions lead to low shear strength in bundles which significantly reduces the commercial application of CNTs. The impact of the VdW interactions can be overcome and shear strength improved via irradiation-induced intertube bonds. However, irradiation also produces non beneficial modifications to nanotube
