Collective modes in flux line liquids

Tanatar, Bilal; Oral, A. (IOP, 2000)

We study the collective modes of flux line liquids such as occur in the type-II superconductors of recent interest composed of two-dimensional layered structures. Starting from the vortex-vortex interaction and employing ...
Direct evidence for the instability and deactivation of mixed-oxide systems: influence of surface segregation and subsurface diffusion

Emmez, E.; Vovk, E. I.; Bukhtiyarov V. I.; Ozensoy, E. (2011)

In the current contribution, we provide a direct demonstration of the thermally induced surface structural transformations of an alkaline-earth oxide/transition metal oxide interface that is detrimental to the essential ...
Nature of the Ti-Ba interactions on the BaO/TiO2/Al 2O3 NOx storage system

Andonova, S. M.; Şentürk, G. S.; Kayhan, E.; Ozensoy, E. (2009)

A ternary oxide-based NO* storage material in the form of BaOZTiO2Zy-Al2O3 was synthesized and characterized. Thermally induced structural changes occurring on the surfaces of the TiO2Zy-Al2O3 and BaOZ TiO 2Zy-Al2O3 systems ...
