China 2 College of Chemistry and Chemical Engineering, Shenzhen University, Shenzhen 518060, P.R.
Surface chemistry, crystalline and pore structures of the GCMs are characterized by scanning electron microscope, power X-ray diffraction and N2 adsorption respectively.
LANO having a similar structure with PAN was prepared by the laboratory.
The crystalline structure was obtained by X-ray diffraction (XRD) (D8 ADVANCE, Germany) using Cu Kα.
The influence of the carbonization temperature may focus on the rearrangement of the crystal structure.

And the structure of diblock polymer was investigated by FTIR.
One of the main method is to synthesize PCL macroinitiator and use click chemistry to obtain the block copolymer[7].

A case study including a detailed ground settlement analysis is made for a particular loess structure located in the city of Galati, Romania, in order to assess the interdependence of geo-environmental and anthropic settlement triggering factors in the urban system context.
An assessment of basic geotechnical parameters, as well as small-scale modeling of loess settlements at wetting under self-weight were conducted in order to select the most representative experimental area, from the point of view of specific soil structure behavior.
Introduction Loess deposits are considered at global scale as one of the major geo-hazards to built environment due to damage in engineering structures and infrastructures caused by large ground settlements [1, 2].
Collapsibility of loess has been attributed to its moisture sensitivity and to the volume changes induced by deformations in a metastable microstructure, linked to soil chemistry and mineralogy [3].
Collapse of loess structures can occur when internal stresses between soil particles or those due to external loads exceed structural strength upon saturation [4].

The change of A980 showed the variations of native starch crystal structure, while the change of A1022 showed the amorphous structure variations.
A980 / A1022 could quantitatively reflect the proportion of the crystal structure and amorphous structure in native starch.
Its native crystal structure was damaged in different degree.

Thus, in this study, a new structure was designed using nadic anhydride (NA) and trialkyl-borate-synthesized nadic dialkyl-ester.
To confirm the structure of the compounds, 1H-NMR spectra (250 MHz , CDCl3) Bruker Advance 250 MHz, FT-IR (DIGILAB-VARIAN, FTS-3100), and HPLC (Acme 9000) were used.

Graphite is made up of a multilayer structure of plate forming beehive-like hexagon rings of carbon elements.
Graphite is made up of a multilayer structure of plate forming beehive-like hexagon rings of carbon elements.
As for carbon nano-structure material, there are CNT, fluorine, and carbon nanocone [3, 4].
Following that, studies are actively conducted in the fields of mechanical property, chemistry, and metal synthesis.
In the result of implementation of network between ASJC, studies on mechanical property, condensation physics, surface coating, studies on physical chemistry and electric chemistry were found to be the center of the studies.
