thermal conductivitythermal diffusivityThe thermal conductivity of oxygen has been measured in a broad region around the critical point by means of Rayleigh light scattering. Measurements were made on two isochores and on the saturation boundary. The results are compared with current methods of ...
Measurements of the thermal conductivity (k) of solid oxygen doped with nonmagnetic impurities of N2 (0.34 and 0.94%) and Ar (1%) were made in the temperature range 1-35 K. It was shown that in the antiferromagnetic alpha phase doping with nonmagnetic impurities has a drastic effect on low...
The thermal conductivity of 99·99 per cent pure oxygen is measured in the conductivity column instrument in the temperature range of 400 to 1600 K from heat transfer data taken in the continuum regime. The results are represented by a cubic polynomial in temperature, viz. k(T)/(mW m-1 ...

Mean grain size increased, while lattice oxygen content decreased, and hence, thermal conductivity increased with decreasing ionic radius of the rare-earth element. In all cases, a marked change was observed in the order of ionic radius from La to Nd to Gd, and a little change was observed ...
Consequently, substantial differences in porosity, uranium-to-oxygen ratio, and, of course, impurities have an important influence on the thermal conductivity. The results on thermal conductivity measurements (some 300 publications) are compared with respect to both experimental conditions and condition ...
The thermal conductivity of nanostructures will also deviate from their bulk counterparts. Conductivity is found to depend significantly on multiple factors, including characteristic size and geometry, heating conditions, interfacial effects, stress, and electric fields. Various cases are considering for ...
