    Notes: Abstract Epitaxial multilayer thin films of “infinite-layer” (Sr, Ca)CuO2 and perovskite (Sr, Ca)RuO3 have been prepared on (100) SrTiO3 substrates by multitarget rf magnetron sputtering. X-ray diffraction analyses revealed that the multilayer structure of (Sr, Ca)CuO3/(Sr, Ca)RuO3 was successfully fabricated with a minimum layer thickness of 20 Å. Transmission electron microscopy measurements of the multilayers indicated that there was no dislocation which normally exists in single-layer films with an infinite-layer structure. Resistivities of multilayer films at room temperature ranged from 1 to 10 mΩ cm and showed semiconductor-like dependence against the temperature.

    Notes: Abstract The behavior of lattice oxygen species of the ferroelectric material during methane oxidation was investigated using a nonthermal plasma reactor packed with BaTiO 3 pellets. Lattice oxygen species in BaTiO 3 play an important role in the formation of N 2 O and the oxidation of CH 4 . The oxidation products such as CO and CO 2 were formed from independent reaction pathways. Lattice oxygen species were able to preferentially oxidize the carbon species deposited on the pellet surface into CO. Also, N 2 O and NO x were independently formed in the N 2–O 2 reaction, suggesting that different oxygen species give N 2 O and NO x. N 2 O was produced by the oxidation of molecular nitrogen with lattice oxygen species.
