1. Engineered Nanostructures and Thermoelectric Nanomaterials
Abstract : This thesis deals with novel aspects of Nanomaterials,Nanoscience and Nanotechnology. On the materials side, novelmethods were developed for the fabrication of nano-sizedbuilding blocks, such as nanoparticles, nanorods and nanowireswith defined structures and high homogeneity. Nanoparticleswere consolidated to nanostructured materials. READ MORE
