Effect of calcination temperature on the structural characteristics and catalytic activity for propene combustion of sol–gel derived lanthanum chromite perovskite

In Table 3, models are presented of carbon nitrides based on the melon structure (the linear form of carbon nitride) and the fully condensed gCN (the network structure) as well

Up to now, superconducting films have been prepared as-grown by an appropriate substrate temperature, or more classicaly, by annealing at high temperature after deposition on a

dination. The Bhatia-Thornton partial structure factors are then deduced. From the partial radial distribution functions the partial coordination numbers are calculated

The image contrast is dominated by photoelectric absorption and scattering is negligible ; thus the resolution is only limited by the wavelength and the energy dose in the

Figure 10: Total structure factors obtained by (a) neutron diffraction, (b) x-ray diffraction and (c) structure factor of first difference determined by anomalous x-ray diffraction

In this study we demonstrate that it is possible to trans- form thin, single-crystalline Y films into the dihydride phase and to unload them again without loss of order. We used
