Characterisation of dispersive systems using a coherer
(Belgrade : International Institute for the Science of Sintering, 2002)
The possibility of characterization of aluminium powders using a horizontal coherer has been considered. Al powders of known dimension were treated with a high frequency electromagnetic field or with a DC electric field, ...
Far-infrared spectroscopy of PbTe doped with iron
(Belgrade: Serbian Chemical Society, 2002)
Far infrared reflection spectra, at room and liquid nitrogen temperature, of PbTe single crystals doped with iron are presented. Plasma minima were observed at about 160 cm–1 and 180 cm–1 for room and liquid nitrogen ...
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 ...
