2. 1. Cerium Oxide Nanoparticles and Gadolinium Integration : Synthesis, Characterization and Biomedical Applications

   Author : Peter Eriksson; Kajsa Uvdal; Caroline Brommesson; Xuanjun Zhang; Zhang-Jun Hu; Duncan Sutherland; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   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.

4. 2. Porous Cerium Dioxide for Catalytic Applications

   Author : Mats Lundberg; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Materiallära; Material technology; catalysis; transmission electron microscopy; macroporous; mesoporous; cerium dioxide; zirconium dioxide;

   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.

5. 3. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

   Author : Magali Ferrandon; KTH; []
   Keywords : wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

   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

6. 4. Low temperature CO oxidation over Pt/CeO2

   Author : Noemi Bosio; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heterogeneous catalysis; Cerium oxide; CO oxidation; kinetic Monte Carlo; density functional theory;

   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

7. 5. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection

   Author : Thirza Poot; Kajsa Uvdal; Linnéa Selegård; Zhang-Jun Hu; Mats Eriksson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. READ MORE
