This thesis focuses on the study of the optical band gap dependence and the determination of the band-gap bowing parameter of the ternary AlGaN, BGaN and BAlN alloys, which are respectively formed by the combination of GaN-AlN, GaN-BN and AlN-BN syst

Water pollution by heavy metals has become a real ecological, societal and public healthproblem. Reliable and fast detection of very low concentrations of heavy ions requires the developmentand design of miniaturized analytical devices, which are non

Lignin pyrolysis produces oxygenated bio-oils with poor fuel efficiency. Hence, they are upgraded through hydrodeoxygenation (HDO) leading to the production of oxygen-free molecules and water as by-product. Our objective is to elaborate new catalysts

Complex metallic alloys (CMAs) are intermetallics with a unit cell characterized by a large number of atoms and a substructure of atomic clusters of high symmetry. Quasicrystals and their periodic approximants are part of this class of materials. Her

Commonly used density functionals have encountered a spectacular success in the modelling of physical, chemical or biological systems. However, they have proven to be unsuitable to describe some situations, such as London’s dispersion forces or str
