The crystal structure of mixture was collapsed into a disordered structure, which increased with increasing grinding time.
A notable change can be observed in the diffraction peak intensity of the mixtures between un-milled samples and samples milled for 30h, as a consequence of the loss of crystal structure produced by the distortion and accumulation of defects in the structure.
The crystal structure of Li2CO3 and Nb2O5 was collapsed into a disordered structure, which increased with increasing grinding time.

The main chain of polyimide molecule generally contains benzene ring and imide ring structure.
According to the design idea, We designed a synthesis method of diamine containing photosensitive chalcone structure.
Diamines containing chalcone structure are the main raw materials for preparing photosensitive polyimide.

With the surface roughness and topography, the surface chemistry plays an important role for osseointegration.
This result is consistent with previous report showing that the nano-structured calcium-incorporated surfaces enhance ossteointegration [12,13].

To obtain fine powders, we used an operation known in solid phase chemistry: doping of nickel formate with the cations of other metals.
The product synthesized by us corresponded to the anhydrous modification with orthorhombic structure.
For instance, electron microscopic images provide evidence that the initial oxohydroxobismuth (III) nitrate trihydrate is composed of rather coarse crystals with the indices of block structure, with a size 30-60 μm in the basis plane and about 10 μm thick.

Introduction Nowadays, the electrochemical performance of lithium-ion battery cathode materials mainly depends on the anionic polymer lithium ion battery cathode material[1], the monoclinic structure of Li3V2(PO4)3 has good structural stability and safety performance is widely used and attractive more and more attention.
Compared with other cathode materials, the prominent advantage of Li3V2(PO4)3 with NASICON structure is high energy in the process of charging, discharging redox potential of high thermal stability and good cycling performance.

Requirements for chelating agents in silicon wafer process Manifold applications exist for chelating agents in science and technology and plenty of literature is available about complex chemistry.
Patri[3] emphasized molecular structure of some chelating agents such as different functional groups, the length of the carbon chain and the relative positions of different functional groups.
Ethylene diamine tetra acetic acid (EDTA) is the most common chelating agent in complex chemistry.

This could be due to the building block of rubber structures that is resistive towards deformation.
The peaks around 1500 - 1400 cm-1 indicate the presence of aromatic ring C=C stretch, from which CA demonstrates a sharp peak signifying a development of graphitic structure [10].

The importance of the structure of the supporting materials for dispersion of the catalyst has been concerned.
These peaks indicated that the Pt was present in the face-centered cubic (fcc) structure.

Since this indicates an increase of the silicate interlayer distance, it should represent the progressive formation of an intercalated structure.
At the die no peak can be identified, thus exfoliated silicate layers could also have been formed simultaneously with the intercalated structures.
