NO2 adsorption on BaO/Al2O3: The nature of nitrate species

Article Abstract:

The nature of the nitrate species formed on Al2O3 and BaO/Al2O3 NOx storage/reduction materials is characterized using temperature programmed desorption, infrared spectroscopy, and (super 15)N solid state NMR spectroscopy. It found two nitrate species, the surface nitrates that are associated with a monolayer BaO on the alumina support, and a bulk-like nitrate that forms on this thin BaO layer.

Enhanced fluorescence of Cy5-labeled oligonucleotides near silver island films: A distance effect study using single molecule spectroscopy

Article Abstract:

Study is conducted on the fluorescence enhancements and lifetime reductions of Cy5 probe molecules at various distances from the deposited silver island film surface using single molecule spectroscopic methods. Varied brightness of fluorophores with distances from metal structures as well with reduced blinking in the presence of silver island films are observed dramatically.
