The alloy properties fundamentally depend on their composition and structure [3-5].
One can clearly see the transformation of the crystalline structure to amorphous one related to the increasing tungsten content in the alloy coating.

Abstract.
Previously reported structures determined by using x-ray and neutron diffraction on hydrides show differences in bond lengths and atomic coordination.
At low temperature, the compound crystallizes in the orthorhombic structure with space group Pnm21 and gradually transforms to a high temperature disordered tetragonal structure with space group I/4mm at about 225K.
The crystal structure of BH3NH3 has been investigated using x-ray diffraction [10-14] and neutron diffraction(ND)[15].
Klooster et al.,[15] have reported an orthorhombic structure based on single crystal neutron diffraction at 200K.

The structure, morphology and absorption properties of samples were characterized by XRD, SEM and UV spectrophotometer.
The crystal structure of samples were characterized by X-ray diffraction (DX-2500 diffractomter, Cu Kα λ=0.15405nm).
It could be seen that there is no obvious diffraction peak that indicates the crystal structure is amorphous.
To the samples at 60 and 80min, the crystal structure is the standard anatase phase.

From the real 3D data, one can create a concentration profile from any arbitrary starting point in any direction intended (or even along a curved structure) off-side of any GBs/TJs, along a TJ/GB, or perpendicular to the GB (Fig. 1.).
Owing to these properties, TAP is the ideal tool in localizing tiny 1D structures such as dislocations [14] or triple junctions [2,13] embedded in a matrix.
Experiments: triple junction diffusion and segregation TJs are line-shaped topological subunits of the GB structure, which are formed by merging of three GBs.
In studying the chemistry of such linear defects, a TAP is the ideal tool since one can identify and quantitatively investigate the composition field of these objects owing to a projection-free reconstruction.
So in the case of the Cu/Ni interface there appears a considerable shrinkage in interface thickness even though the chemistry of the system suggests further broadening by interdiffusion.

Base materials, foamed nickel and copper (Cubic crystal structure), make slight impact on homogeneous nucleation.
Fig.2 Miller index in HCP structure. β-Co(OH)2 belongs to Hexagonal, P3m1.
The main categories of Co(OH)2 are showed that α-Co(OH)2 has a structure of similar hydrotalcite which is a typical structure of the layered double hydroxide composite metal oxides, and β-Co(OH)2 has a brucite structure with octahedral structural layer in where hydroxyl ions is hexagonal close-packed and cations fills in all octahedral voids, which between each two adjacent hydroxyl ions.
Compared to the situation of the sample grows on nickel foam, the sample on Cu sheet is corroded lightly, which indicates that copper structure is firmer than the network structure of nickel foam.
