Introduction
Exploring the new nano-structure has become one focus topic in recent years in physics, chemistry, materials science, biology and other research fields.
And this new nano-structure has attracted wide attention.
The octahedral [Al (OH)n (H2O)6-n](3-n)+ in solution can only form of AlOOH structure.
And two-dimensional sheet structure will be generated.
Crystal surface structure and its growth units of anionic coordination polyhedra [J].

The structure of extracts from CDLR was characterized by using IR.
The heavy oils and asphaltenes of CDLR have the basic structure unit of raw coal.
Sizes of anions and cations of magnetic ILs are large, but the structures are asymmetry.
Molecules of ILs will get into CDLR to expand the reticular structures of CDLR, releasing more small molecules; Besides, the organic cations of ILs are ring structures having heterocyclic atoms, such as nitrogen atoms.

This model, based on contemporary understanding
of microstructure evolution and the interaction of dislocations with microstructure essentials, gives
a reasonable description of the hardening behaviour and accounts adequately for changes of material
chemistry, in particular for age-hardened alloys.
The cast billet shows a dendritic structure with large grains with a mean size of 80µm and mainly primary Mg2Si and AlFeSi precipitations.
Remarkable is the change of the precipitation structure.
The grain structure shows large grains, extending the EBSD-image, which could be some hundred microns long, and smaller grains also showing elongated structure.
The quenched sample exhibits a distinct subgrain structure with high stored deformation energy, coarse elongated grains and small subgrains whereas the air cooled sample shows a coarsened subgrain structure and new formed high angle grain boundaries during static recrystallization.

Methods
Structure Preparation.
The H243L mutant of Bacillus subtilis levansucrase (LSH243L) structure file was made from its wild-type (LSWT) crystal structure (PDB code: 1OYG [15]).
This process modeled all the missing atoms present in the LSWT structure file.
The conformation of the docked sucrose also highly resembles the crystal structure.

The compound has an orthorhombic perovskite structure and a fine and homogeneous grain size distribution, with a mean value of 0.4 mm.
The partial substitution of the tetravalent Ce4+-site by trivalent cations generates oxygen vacancies into the perovskite structure by charge compensation.
This partitioning is accompanied by some barium oxide evaporation at high temperatures, ensuring that the overall Ba/Ce mole ratio in the perovskite structure remains close to 1.
Many studies have been conducted to understand the structure, defect chemistry and conductivity of doped barium cerates.

In this regard, the fire protection of existing wooden structures and products is relevant today [1–3].
This is due to the release of physically bound water from the structures of aluminosilicate paint bases.

Cubic structure of all has been confirmed by XRD.
Alloys having a uniform internal structure are homogeneous alloys, and if compositions and structures are varied, are gradient alloys.
For all three samples cubic structure is observed.

., point, step, and groove) were examined in terms of interaction energy, morphology and structure.
It has been shown experimentally that surface defects of metal oxide substrates, such as vacancies (point defects), steps, grooves and kinks, significantly affect the adsorption and final structure of deposited metal clusters [6-9].
It was believed that these point defects could strongly influence the morphology of deposited particles and the surface chemistry of TiO2 [1].
Their corresponding defect structures have about 1.2 and 2.0 Å in depth.
The aggregation induced by such network structure was also observed in our experiment.

Increasing concerns about negative environmental impacts of building structures call for higher demands on the design of environmental friendly buildings.
The fundamentals anchored in ISO standards and SETAC are well structured, therefore generally applicable in industry.
The horizontal structures were realized as reinforced concrete ceiling with EPS-based thermal insulation above the ground floor.
The roof structure is flat with gravel ballast layering.
Horizontal structures are entirely wooden.

It was shown that the solidification structure was refined with the addition of Ti element.
The solidification structure of Zn-11Al-3Mg alloy consisted of dendritic Al-rich phase, white granular or strip-shaped Zn-rich phase, gray hexagonal MgZn2 phase and Zn/Al/MgZn2 ternary eutectic structure, as shown in Fig. 1 (a).
The entire dendrite was petal-like and the dendritic phase was dispersed in the solidified structure.
The SEM photos of the solidification structure of the alloys with different Sb contents are shown in Fig. 2 (c-f).
