This offers the possibilities of providing synthesis of OC with a priori given structure.
The progress of aircraft since 1930, increase of capacity and working rate of machines caused the growing demand for metal structures and mechanisms.
The released H by dissolution of steel crystal structure bonded with dissolved O2 and its content in anolyte decreased, which permits photomertric determination of H evolved in anolyte.
Heating for 8 h at 470 K results in effective desorption of H, but 5-6 mL H2/100 g of manganese steel is enclosed in defects of crystal structure mainly as gas.

Introduction Zeolites are a large group of crystalline, porous materials with a broad diversity of structure, porosity and chemical composition.
This new structure can be interpreted as a foam structure.
By using a special type of synthesis mixtures (clear solutions with low viscosity) it is even possible to synthesis homogeneous zeolite layers on microcellular structures with a cell size in the µm-range [34].

It implies disorientation of cellulose structure in the surface after modification with GMA.
These results were also reported [11] that GMA-grafted cellulose nanocrystals (CNC) showed a loss of CNC crystal structure after grafting which resulted in changes to the NC crystal structure and reduced peak intensity in GMA-grafted CNC.
The 20% GMA grafted cellulose sample experienced two stages of weight loss, where the first stage occurs at a temperature of 30-1000C caused by water loss in the grafting cellulose structure.
The second stage occurs at a temperature of 240-4800C, experiencing thermal degradation of the grafted cellulose structure.
XRD data shows that GMA grafted cellulose experienced a slight decrease in crystallinity which implies GMA only slightly affects the cellulose structure, although disorientation of the cellulose structure occurs.

This result indicates that the Cu-Mn based catalyst made by pure NaOH precipitator shows strong physical structure, whereas the sample made by KOH precipitator has weak structure.
The dried Cu-Mn sample precipitated by the pure KOH only consists of the hydrate basic copper sulfate, Cu4SO4(OH)6·H2O (JCPDS 20-0364) with a typical layer-structure[4].
It is interesting that the all dried samples were transferred to the spinel structured Cu1.5Mn1.5O4 after calcining at 550℃ (Fig.2-b) no matter what precipitator were used.
Conclusions Precipitating agents, KOH and NaOH, are important parameters to affect phase structure and texture of the Cu-Mn based WGS catalyst, especially the activity and stability of copper-manganese WGS catalyst.
This is a structure weak material and was transferred to low surface area, and low intensity of solid solution, Cu1.5Mn1.5O4 and then to microcrystalline Cu and MnO, which resulted in poor catalyst activity.

Beading is a common phenomenon which causes electrospun fibrils to form a chain-like structured fibre with irregularly sized “beads”.
This opens up new avenues for applications which require the maximum specific surface area possible, which may only be obtained within nano-scale structures.

The experimental steps are reduced and the temperature is lowered which are conducive to the formation of porous structure[8,9].
As the electron pair center of both donor and acceptor, ZnCl2 can react with hydroxyl groups of cellulose complex, leading to cleavage of the chemical bonds between cellulose molecules and formation of chain-like cellulose molecules which is easily cyclized to form condensed benzene planar structure.Thus the condensed carbon structure of microporous or mesoporous generates.
Analysis of hydrolysis and preparation process Formic acid is a small organic molecule with flat structure.
Consequently, formic acid molecules with total bond lengths less than 0.224 nm are easy to enter sugar based spatial structure and break the hydrogen bond structure existing in molecular chain.The holocellulose dissolved in acid solution gradually along with more and more formic acid molecules get in and the β-1,4-glucosidic bonds break because of the catalytic hydrolysis by H+,thus, the hydrolysis reaction occurs.

The advantage of traditional anodizing is the ability to form oxide layers with a regular structure and a controlled length of the pores [3].
We use such approach to obtain WO3 – MWO4 oxide structures (M = Fe, Cu, Ni, Mn, Zn) on titanium.
In the absence of acetonitrile, catalytically active leaf-like structures with high concentration of Mn (46.0 at. %) grow on the surface of PEO-coatings (Fig. 2a, b, d).

In general, crystal structure of PLA shows the WAXD pattern of a (110)/(200) reflection and a (203) reflection [8].
This suggested the PLA sheet consisted of mainly amorphous structure without an alignment.
This hinted that crystal structure of PLA was nucleated but randomly dispersed in the sheet sample.
Moreover, a two-point SAXS pattern was observed along machine direction, indicating arrangement of lamellar structure with a long period of 25 nm.

It was found earlier that electrolytes with a submicrometer- or nanometer-scaled structure can have an improved charge transport performance [4].
Therefore, it would be reasonable to prepare fully dense YSZ ceramics with a submicrometerscaled structure and analyze their electrochemical properties.
The LSM powder of the second type (LSM2) had the composition La0.7Sr0.3MnO3 and was prepared by pyrolysis of a polymer-salt mixture (polyvinyl alcohol and nitrate salts) at the Institute of Chemistry of Solids of the Ural Branch RAS (Ekaterinburg).
This image shows that the structure was characterized by developed infrastructure of irregular channels with the linear dimensions of pores from 1 to 5 microns.
LSM grains in this structure represented consolidated aggregates up to tens micrometers in size with a great number of necks.

The mechanical properties of gray iron primarily depend on the matrix structures, while matrix structures are chiefly decided by chemical constitution.
The gray iron structures do not contain free cementite because of about 2% silicon in gray iron.
Reducing carbon equivalent can refine graphite, but easily appear white iron structure and apt to D-type graphite as abnormal inoculation [1].
When the content of antimony is between 0.02% and 0.06%, the structure of matrix is pearlite mostly.
