Selective sodium removal from lithium chloride brine with novel inorganic ion exchanger Li1.4Al0.4Ti1.6 (PO4) 3 JianZhi SUN*, Yan Dong, ChunYan Kong Key Laboratory of Coordination Chemistry and Functional Materials in Universiities of Shandong, Dezhou University, Shandong Dezhou 253023, P.
LiTi2 (PO4) 3 possesses the NASICON-type (Sodium super ion conductor) structure, composed of both MO6 octahedra and PO4 tetrahedra which are linked by their corners to form a three-dimension (3D) network structure.
The resulted structure consists of Type I and Type II sites for the mobile Li ions to occupy.
The X-ray diffraction study clearly shows that Al3+ dopant did not affect the structure of the material [6].
In fact, bands in this region of the spectrum are often due to condensed phosphate groups such as P2O74− or extended polyphosphate structures.

From hot rolling to the finishing treatment the metal goes through a complex procedure including several cycles of rolling-annealing (straining-recrystallization) in which its structure and texture change substantially.
The strip consists of Fe–3% Si industrial alloy with single-phase ferrite structure (grain oriented electrical steel with copper nitride inhibition [5, 6]).
The large deformation caused by a certain state of stress leads to the appearance in the structure of a set of stable orientations [22].

The surface of AAO film formed possessed irregular structure with small pores.
The structure of pore was more circular with large opening.
The formation of AAO porous structure on the surface of AAO film was due to the dissolution of oxide layer.
The pores structure became more circular and uniform.

Through the CRISPR sequence structure and mechanism of performance are hot in research to study the thermophilic streptococcus [2, 3].
The study of CRISPR sequence structure of streptococcus thermophilic in dairy, provides the foundation platform for the construction of the phage resistant mutant strain and food safety for the development of wild thermophilic streptococcus phage resistant strains as well as reduces the losses due to pollution of phage that has major significance [7, 8].

Unfortunately, no matter applying THF or CH2Cl2 as solvent, the micro-/nanostructures are badly distributed, and moreover, they show a highly defective structure.
Compared with the well-defined nanocubes, the samples not going through a thermal annealing procedure have a much less regular and structured morphology.
As shown in Fig. 2a, b, when the experiment is carried out at 50oC, comb-like structures with smooth surfaces are gained.
The adjacent wires standing one-by-one in a line are occasionally fused together at the end of the slices leading to brush shapes structures, which have underlying trend to form a plate.

These building blocks are capable of producing of two-and three-dimensional structures (fig. 2).
Three – dimensional structure of geopolymers During synthesis of geopolymer the silicon and aluminum atoms form healthy, branched Si-O-Al-O, chains to which geopolymer do not step on the mechanical properties of natural stone.
According to Davidovits, the reaction of obtaining of geopolymers proceeds in three stages, (fig. 3): - First stage - performed dissolution of oxides of silicon and aluminum in alkaline environment - a concentrated aqueous solution of NaOH or KOH; - Second stage - the separation of natural polymeric structures of the monomers; Fig. 3.

Gold nanomaterials with various shapes from zero-dimensional (rods) to three-dimensional (nanostars, multipods, nanoflowers structures have been produced [6, 7].
The morphology and structure of the as-prepared SGNPs werecharacterized by SEM and TEM.
The structures of SGNPs produced at different concentration of hydroquinone were compared in Fig. 2A-2D.

The XRD-patterns of carbon fibers shown in figure 2 demonstrates that the fibers have carbon turbostratic structure. 8.00 µm Fig 1.
They are connected and distributed in whole structure.
The internal pores are correctly connected to external surface as complete structure of ACFs [1].
These surface oxygen complexes exhibit a broad range of chemical stabilities and because of this, the chemistry of these complexes is a function of temperature of formation and subsequent thermal treatments [8].
In general, the ACFs adsorb the vapors well if their structures are distributed mainly by internal micropores and mesopores which connected directly to surface.

The morphology and structure were examined with scanning electron microscopy (JSM-6510).
Fig. 1 Equilibrium phase diagram The cast structure of NiCr20TiAl superalloy was dendritic morphology.
When treated at 1140℃ for 8 hours, AC, the dendritic structure disappeared, and no carbide existed in the grain interior or along the grain boundary.
Fig. 5 shows the structure of NiCr20TiAl superalloy treated at different solid solution treatment temperature and then aged at 700℃ for 16 hours (T1~T5).

Introduction Compounds TlGaSe2, β-TlInS2 have a layered structure; therefore, we assume that it is more than likely that they have anisotropic optical properties.
It is said in [10, 11] that crystals of the TlInS2 type have a pseudotetragonal structure with a point group of Р21/m.
