Medium-sized structures vertical

Fig. 7 Cubic perovskite crystal structure of high-symmetry parent compound KZnFa. Large spheres are cations, K+, medium-size dark spheres are anions, F, and small black spheres are metal ions, Zn. Metal-ligand octahedra share common vertices. (From [18])...

Figure 7.18 The anion-centred polyhedron (rhombic dodecahedron) found in the cubic closest-packed structure (a) oriented with respect to cubic axes, the c-axis is vertical (b) oriented with [111] vertical (c) cation positions occupied in the halite, NaCl, structure (d) cation positions occupied in the zinc blende (sphalerite), ZnS, structure (e, f) the two anion-centred polyhedra needed to create the spinel, MgAl204, structure. Cations in tetrahedral sites are small and cations in octahedral sites are medium-sized. Adapted from E. W. Gorter, Int. Cong, for Pure and Applied Chemistry, Munich, 1959, Butterworths, London, 1960, p 303...

This section successively reviews four cases of nuclear new build in different market structures first, the US nuclear merchant South Texas Project of the NRG Energy group second, the consumers consortium project of Okililuoto in Finland third, the large vertical company nuclear project (EDF s Elamanville EPR) and fourth, some hypothetical projects from oligopolisitic medium-sized vertically integrated companies such as are likely to occur in the UK. 

Another potential vertical medium is not a continuous thin film, but rather an assembly of metal particles deposited in well defined pores in an alumina film on Al [109-117]. The shape anisotropy of the particles gives the desired vertical anisotropy. In producing such structures, the proper conditions for the anodization of the Al disk and for the subsequent control of pore size are as important as the conditions of metal deposition. The structures of such disks are discussed in detail below.
