The homogeneous Cu-ZnO and heterogeneous Ag/ZnO nanorods were synthesized by controlling the ionic radius of Cu and Ag with lattice of ZnO. The structure of Cu-ZnO and Ag/ZnO was investigated by a series of methods. The study of the photoelectric properties suggested both of the homogeneously...

Goldschmidt, particularly as the radius always appeared doubtful. The reference is simply a clerical error. Prof. Goldschmidt's letter does, however, raise a point of some importance. While it is true that copper lies between nickel and zinc in the Periodic Table, it is far from true to ...

The radius of the ionic aggregate in PI–xNa is approximately 0.96 nm irrespective of the neutralization level (Fig. 2b). This type of consistency is generally observed for ionomers because the aggregation of neutralized and unneutralized carboxyl groups is limited by steric interactions between...
All models can be inspected at any orientation and zoom level and with a choice of the drawing radius for the ionic spheres. For any given ion, a “clipping sphere” can be defined that highlights the local surroundings of that ion and hides the remaining structure. Distances between ions ca...

(ion radius of 2.20 Å); this value is probably at the lower limit since we have considered the ideal migration path normal to the unit cell face. In addition, neutron diffraction55and quasielastic neutron scattering23studies confirm a high level of orientational motion of the CH3NH3+ion...
