2. Electrochromic nanostructures based on tungsten trioxide for reflective displays
Abstract : Our lives are dominated by the usage of displays. Every day we spend hours looking at displays and our eyes are surely affected by them. Reflective displays have gained a lot of attention in recent years due to their lower impact on our eyes' health, very low power consumption, and high performance in sunlight. READ MORE

4. Nanostructures Studied by Atomic Force Microscopy : Ion Tracks and Nanotextured Films
Abstract : The work presented in this thesis concernes two sorts of nanostructures: energetic-ion-impact-induced surface tracks and gas-deposited WO3 nanoparticles. Our aims to characterise these nanostuctures and understand the physical principles behind their formation are of general interests for basic science as well as of the field of nanotechnology.
