Enhance the durability of IrRuOx catalyst by inhibiting the migration of intra lattice oxygen.5%-Nb in lattice can strengthen Ir/Ru-O bond, increase oxygen migration barrier, keep catalyst stable.DEMS reveals that lattice-doped Nb suppresses the migration of bulk lattice oxygen to surface oxygen ...
Surfaces, interfaces and grain boundaries are classically known to be sinks of defects generated within the bulk lattice. Here, we report an inverse case by which the defects generated at the particle surface are continuously pumped into the bulk lattice
c, Comparison of the obtained lattice parameters (a and b) as a function of the pressure. Although both space groups can refine the data equally well, the refinement results using the orthorhombic Fmmm space group at higher pressures show that a and b merge together, indicating the symmetry ...

In contrast, calcium ion, of larger size, exhibit the same diffusion rate as nickel and cobalt ions in the lattice. However, the parameter D′α/D is one order of magnitude higher. This can be explained by a strong interface segregation of calcium. The case of chromium is particularly ...
In the following, the theory of hydrogen bulk diffusion in ferritic steels is summarized17,18,35,36, which is based on lattice diffusion and on the local equilibrium between lattice hydrogen and trapped hydrogen. Trapping sites are known to increase the saturation but to decrease the long-range...

Sphalerite always contains some Fe in the lattice, which determines the maximum possible Zn concentrate grade. Although galena and sphalerite (including marmatite, sphalerite with high Fe) are the major ore minerals, cerussite (PbCO3), anglesite (PbSO4), and smithsonite (ZnCO3) can also be ...
