The composition-dependent basal-spacing of the mixed-alkali layered perovskites Cs x Rb 1 x Ca 2 Nb 3 O 10 , has been measured over the range, 0 ≤ x ≤ 1 using high resolution X-ray diffraction and is compared with previous results on other layered solids. The perovskite results are ...
The generalized softening of the phonon frequencies when moving from the AFM to the FM phase is indeed consistent with a phase transition volume expansion of ≈ 0.4% at ain = 3.92 Å. Taken these effects alone, however, the thermal conductivity of the FM phase should be the ...

Sintering and crystallization behaviour of a glass powder and block with a composition of anorthite and the microstructure dependence of its thermal expansion Two kinds of glass specimens were prepared in the form of powders and blocks with anorthite compositions, and an examination was made of the ...
studying the effects of gasoline contamination on the geotechnical properties of this soil type becomes very crucial. Hence, in case of further expansion of these constructions and the occurrence of oil pollution, geotechnical engineers could consider the results of this study before the project and ...
The corn pericarp was obtained from byproduct of nixtamalization process which contains water, calcium hydroxide, soluble solids, and pericarp. The studied parameters were temperature (120–140°C), moisture (200–400 g/kg), and corn pericarp (200–400 g/kg); the responses were expansion ...
Anharmonic effects in the thermodynamic properties of solids III. A liquid gallium immersion dilatometer for the range 50-700 °C: thermal expansivities of Hg, Ga, NaCl and KCl A liquid gallium immersion dilatometer has been developed which is suitable for measuring thermal expansion coefficients ...
Effect of partial denervation and terminal field expansion on neuromuscular transmitter release and nerve terminal structure The efficacy of evoked release by intact and newly sprouted terminals in response to partial denervation and expansion of the motor neuron terminal field w...
