The technological advances in areas such as automotive and aerospace industries require materials capable of withstanding demanding conditions. Surface treatments are...

The adsorption of gases in micro/mesoporous materials and solubility of gases inliquids are physical phenomena well known. On the other hand, solubility of gases in...

Works done during this thesis split into two main themes, themselves subdivided in several projects. On the one hand, works have been led concerning the analysis and...

The research work presented in this report, concerns the synthesis and the study of the coordination properties of the 64Cu by new acyclic chelators for PET imaging.We...

The main objective of this work is to study the oxidation mechanisms of UV-A photocatalysis on TiO2 applied to the degradation of microorganisms and their effects on...

The aim of this thesis is to understand and improve the sulphidation of W-based hydrotreating catalysts by understanding and characterising each step of their...

This thesis concerns the design and implementation of novel auto-immolative spacers for use in probes for enzymatic activity in vivo.The first part relates the...

Superplasticizers are admixtures developed to give the cementitious materials greater fluidity for the same water to cement ratio (w/c), promoting the particles...

Understanding the function of RNA involved in biological processes requires a thorough knowledge of RNA structure. Traditional chemical and enzymatic reagents and...

This thesis investigates the catalytic steam reforming of methane with CO2 capture. The selected bi-functional catalysts consist of nickel, effective in steam...
