Graphene oxide (GO) is an oxidized nano-sheets of graphite with a 2D planar structure.
These multiple-folds and wrinkle-like structures are due to the alteration of sp2 planar structure into sp3 tetrahedral structure caused by carbon oxidation.
Oxygenated functionalities could be used for chemical linkage by various methods such as carbodiimide chemistry (EDC/NHS), glutaraldehyde, amidic bond, aminophenyl boronic acid, and biotin-streptavidin interactions [26].
SEM images confirmed the exfoliation of graphene sheets and their flake-like structure.

This integral structure has excellent performance of easy installation and good maintenance, effectively avoiding scratching strip surface.
Collecting Ring of the Detecting Roll The role of collecting ring is achieving static output of the original shape signals of the high-speed rotation sensor, and its structure significantly affects stability and accurate of the shape signals [8], as shown in Fig. 5.
So the detecting roll is usually machined as hollow cylindrical structure to reduce the rotational inertia.

The surface morphology and chemical structure of each films were studied by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR), respectively.
Characterization of biocomposite films The chemical structure is one of parameters which affected to physical properties of biocomposite films.
Therefore, we started to investigate the chemical structure of PLA, CF and biocomposites by using FT-IR technique, scanned in the range wavenumber 4000 cm-1 - 400 cm-1 (model FT/IR-4600, Jasco, Japan).
This behavior possibility due to the CF has hydrophilicity because of the hydroxyl groups within its structure.
This is probably due to the effect of functionality of chemical structure of CF that has hydrophilic property.

SAXS technique from synchrotron radiation source was used to evaluate the hybrid PVA/TEOS/GA structure at the nano-order level.
Vector q (A -1) assuming a semi-crystalline structure of PVA polymer sample.
Hydrogen bonds are very important on stabilizing polymer structures.
Such trend is assumed to be caused by breaking most nano-ordered tri-dimensional organic structured previously found in the PVA sample.

Introduction The asphalt pavement as a no juncture of continuous type pavement, have good mechanical strength, good endurance, driving smoothly and comfortable without dust, no vibration, low noise and the mechanical construction, it has become the principal forms of the road surface structure form in China today, according to statistics about 95% of the highway for asphalt pavement.
The typical structure of pavement is shown in table 1: Various pavement damages take places since Huaijiang highway was completed and open to traffic in November 2000.

The first is the quality problems of aggregate, on the choice of aggregate must consider the chemistry between the aggregate and asphalt and have good gradation composed; the second is the content of asphalt is too high; The third is the porosity of asphalt mixture is too large; the fourth is overloaded phenomena exists; the fifth is the influence of the environment and climate, this district is located in the Yangtze river, the summer time long, much rain, the high temperature; the sixth is the quality of construction, especially compaction degree can not meet the design demand.

And the influence of anodizing duration on the structure and anti-corrosion performance of anodized film of AZ31 magnesium alloy was also investigated.
The film anodized for 5 min has a micro-porous structure with small cracks as shown in Fig. 2(a).
The micro-porous structure is the result of the contraction of the anodizing film when the molten oxides formed in anodizing process are cooled by electrolyte.
The reason is that the structure of anodizing film is destroyed by the devastating sparks in late stage of anodizing.
Then the corrosion resistance of film decreases when anodized in the forth stage, in which the structure of anodized film is destroyed by the devastating sparks.

Since the chemistry of TPF and TAM steels was the same, the difference of the microstructure was due to an additional austenitizing and oil quenching step.
According to the research by Law et al [9], when martensitic structure was re-heated to the intercritical temperature, the acicular austenite (γa) formed between martensite laths, and granular austenite (γg) formed at prior-austenite grain boundaries and the packet boundaries of the lath martensite.
The blue areas were FCC structure which referred to retained austenite in this paper, and the grey areas were BCC structure.
We could also be observed in the EBSD morphology that, there were many dark regions which were block structures containing martensite or bainite formed from block intercritical austenite.
