Traditional analysis of reactions catalyzed by supported metals involves the structure of the metallic particles. However, we report here that for the class of nanostructured gold- or platinum-cerium oxide catalysts, which are active for the water-gas shift reaction, metal nanoparticles do not participate in the reaction. Nonmetallic gold or platinum species strongly associated with surface cer...

According to UV-visible spectroscopy, X-ray diffraction spectrometry, dynamic light scattering, Fourier transform infrared spectroscopy, electron paramagnetic resonance spectroscopy, transmission electron microscopy, scanning electron microscopy and X-ray photoelectron spectroscopy, nano-sized manganese oxides are proposed as active catalysts for water oxidation in the reaction of some manganes...

Doğal biyolojik polimer olan ahşap malzemenin, diğer yapı malzemelerine kıyasla önemli avantajları bulunmaktadır. Ancak malzeme, dış ortam koşullarında dayanıklı bir yapıya sahip olmadığı için mutlaka emprenye edilerek veya çeşitli üst yüzey işlemleri yapılarak kullanılmalıdır. Bu çalışmada, sarıçam (Pinus sylvestris L.) örnekleri %0,1; %0,2; %0,5; %0,7; %1; %2; %3; %4 ve %5 konsantrasyonda nan...

The silicon–cerium oxide interface is studied using x-ray photoelectron spectroscopy. The oxidation and reduction of species at the interface are examined as a function of annealing temperature both in vacuum and oxygen ambient, in order to determine their relative stabilities. By depositing a very thin CeO2 film ~;30 Å!, the cerium and silicon core level peaks can be monitored simultaneously. ...

The aims of our experiment were to evaluate the uptake and translocation of cerium and titanium oxide nanoparticles and to verify their effects on the growth cycle of barley (Hordeum vulgare L.). Barley plants were grown to physiological maturity in soil enriched with either 0, 500 or 1000 mg · kg(-1) cerium oxide nanoparticles (nCeO₂) or titanium oxide nanoparticles (nTiO₂) and their combinati...
