1. Cerium Oxide Nanoparticles and Gadolinium Integration : Synthesis, Characterization and Biomedical Applications
Abstract : A challenging task, in the area of magnetic resonance imaging is to develop contrast enhancers with built-in antioxidant properties. Oxidative stress is considered to be involved in the onset and progression of several serious conditions such as Alzheimer’s and Parkinson’s disease, and the possibility to use cerium-contained nanoparticles to modulate such inflammatory response has gained a lot of interest lately.

2. Porous Cerium Dioxide for Catalytic Applications
Abstract : Mesoporous cerium dioxide with high crystallinity has been synthesized and studied by TEM, SEM, nitrogen adsorption, PXRD, AFM, and SAXS. The catalytic properties of the materials have been investigated The results of the catalysis experiments were correlated with high resolution TEM investigations of the corresponding material, and it was found that the exposed crystallographic facets play an important role in the conversion of carbon monoxide to carbon dioxide.

3. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide
Abstract : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. READ MORE

4. Low temperature CO oxidation over Pt/CeO2
Abstract : The oxidation of CO to CO2 is a widely studied reaction not only for its practical applications but also for its apparent simplicity. CO oxidation is, in fact, often used as a model reaction for other oxidation reactions. READ MORE

5. Lithium intercalation in tin oxide films : Physics and electrochemistry
Abstract : Tin oxide films were made by reactive rf magnetron sputtering under conditions that led to both electronic and ionic conductivity. It was found that a high sputter pressure promoted porosity and a high charge capacity. READ MORE
