The capacity of nodulating bacteria to survive in soil containing various heavy metal elements has been investigated with the aim of promoting the revegetation of mining sites with Medicago sp. Soil samples were collected from three different mining sites and one agricultural site at a location north of Tunisia. Heavy metal composition analysis showed that(More)
We report the preparation of a new type of nanocomposite containing cobalt and silver nanoparticles organized in parallel layers with a well controlled separation. This arrangement allows the observation of an enhanced low-frequency Raman signal at the vibration frequency of cobalt nanoparticles excited through the surface plasmons of silver nanoparticles.(More)
INTRODUCTION Scientific report According to project objectives, namely to grow and to evaluate the structural, electrical and optical properties of nanostructures in the Si-Ge-C system and to gain insight into fundamental physics of these structures, and to improve the luminescence efficiency of these structures, and according to the work plan for the(More)
