The development of new open shell systems is essential for advances in spin science. In this work, we report the synthesis and characterization of three nanostructured materials, namely SBA-15 silicas, periodic mesoporous organosilica (PMOs) and lamellar polysilsesquioxanes, all functionalized with the same diazene-based precursor of phenoxyl radic...
Nanostructures were built at the solid/liquid interface by self-assembly and/or coordination bonds. Metalloporphyrins bearing two external coordination sites and long alkyl chains allowed the self-assembly of the compounds on highly oriented pyrolitic graphite. After addition of a metal ion, long transition-metal linked porphyrin nanoribbons were o...
Low vulnerability gun propellants are energetic materials specifically designed to resist unintended initiation stimuli and aim at replacing the usual nitrocellulose (NC) based ones. As a result, low vulnerability gun propellants are more difficult to ignite than conventional propellants. In order to achieve efficient ignition, it is essential to s...

In Situ Chemical Oxidation (ISCO) can be applied to soils contaminated by polyaromatic hydrocarbons (PAHs). PAH degradation yields are often rather low, because of different obstacles not clearly understood. These include the low availability of PAHs, the type and age of soil organic matter and the carbonate content of the soil. The aim of this wor...
