The effect of ageing on YBa2Cu3O7-x obtained by the photoacoustic method
(Belgrade : International Institute for the Science of Sintering, 2003)
Thermal diffusivity and electric transport properties of fourteen years old superconducting YBa2Cu3O7-x pellets were obtained using the photoacoustic transmission technique and then compared with freshly made superconducting ...
Influence of solvent on the structural and morphological properties of AgI particles prepared using ultrasonic spray pyrolysis
(Materials Chemistry and Physics, 2008)
Silver iodide particles were synthesized in the process of ultrasonic spray pyrolysis using aqueous solutions of thermodynamically stable silver iodide clusters as precursor. The AgI particles were collected in solvents ...
Effect of ageing on optical and thermal properties of YBa2Cu3O7–δ
(International Journal of Materials Research, 2007)
Photoacoustic phase and amplitude spectra of YBa 2 Cu 3 O 7 – δ samples synthesised 18 years ago were measured and numerically analysed. The value of thermal diffusivity obtained on the aged samples was lower than the ...
