Adsorptive Removal of Dibenzothiophene in Diesel Fuel on an Adsorbent from Rice Hull Activated by Phosphoric Acid Guo-Xian Yu1,2*, Jing Sun2 , Xiao-Ming Hou2* , Xiao-Long Zhou2, Cheng-Lie Li2, Lifang Chen3* , Jin-An Wang 3 1 School of Chemistry and Environmental Engineering, Jianghan University, Wuhan 430056, China 2 School of Chemical Engineering, East China University of Science & Technology, Shanghai 200237, China 3 ESIQIE, Instituto Politécnico Nacional, Av.
Recently, much attention has been paid to the carbon-based adsorbents for adsorptive desulfurization because of their higher surface area, satisfactory porous structure and the abilities for surface chemical property modification.
The effect of the silica removal from the adsorbent on the combination of textural structures, surface acid properties and adsorption behaviors for DBTs will also be concerned. 2 Experimental 2.1.
Textual structures and surface acid properties of adsorbents Textural structures of the phosphoric acid-functionalized RH samples were listed in Table 2.

Thirdly, colloidal microspheres are removed by high temperature with an ordered macroporous structure left, consisting of periodic structure of air voids in a solid-state matrix.
There are large area of single crystal structure shown in figure 2(a).The high magnification image of inversed opals structure in figure2 (b) indicates that the structure is the precise inverse structure of the colloidal crystal templates.
Periodic structure like this is easy to form band gap structure.
(b)Smooth surface; (c) hierarchical structure of the ZnO surface.

The phase structures of samples were investigated by using X-ray spectrum and steady-state fluorescence spectrometer.
We systematically investigated the effect of different sintering temperatures on the crystal structure and optical properties of Cs3Cu2I5 powder.
The crystal structures of the Cs3Cu2I5 powder phosphors were determined by powder X-ray diffractometer (Panalytical).
The samples can form an orthogonal structure of Cs3Cu2I5 phase at a sintering temperature of 100-400℃, and the space group is pnma.

A Composite Scales Heavy Anti-corrosion Coatings use in the Marine Structural Facilities Su Manrong1,a ,Huang Fuchuan1,Tang Xingzhong2,b ,Lan Minxing2 , Xiao Youcheng2,Liang Hui2,Li Sheng2, c 1 School of Chemistry & Chemical Engineering of Guangxi University, Guangxi Key Laboratory of Petrochemical Resource Processing and process intensification Technology, Nanning 530004, China. 2 School of Chemistry & Chemical Engineering of Guangxi University, Guangxi Key Laboratory of Petrochemical Resource Processing and process intensification Technology, Nanning 530004, China.
Known from research process: build in marine engineering, where conditions is very harsh , structures requiring protection for a long time; actual seawater corrosion conditions shows, most serious corrosion in marine structures with - Inflatablemore areas.
Therefore, marine structures, facilities are required to used heavy anti-corrosion coatings in various structural parts.
Where in the most important class of a bisphenol A type epoxy resin, its molecular structure is between the reactive epoxy groups is characterized by a molecular bond, an epoxy group may be located at the molecular chain end, the middle or annularly structure.
(2).Composite scales heavy anti-corrosion coatings adhesion is strong, excellent corrosion protection, ease to marine engineering, field conditions to use,it can be protect metal structure, also protect non-metallic structure.

Sulfide Fe1-xS has loose structure, and it is easy to fall off.
Steel structures in coastal muck soil free of industrial pollutants is unlikely to corrode in this way.
Because the muck soil regions in the sea are hypoxic, the oxygen-absorbing corrosion of steel structures in coastal muck soil stops at cathode polarization.
The SRB in the soil impose corrosion risk to the steel structures(steel pipe piles and concrete pipe pile joints) in hypoxic environment.

This structure exhibited the smallest particles size, which is 83 nm.
The Co nanoparticles prepared in other concentrations were irregular structure without flakes.
All the pure Co microstructure exhibited the irregular morphology structure.
The alignment of dendritic in such a manner will form the snowflake-like structure.

It was found that as-sprayed sensor tubes have a lamellar structure.
After sintering, the lamellar microstructure changed into granular-type structure.
These phases are dependent upon feedstock chemistry, thermal histories of the particles, solidification rates and temperature of the deposit.
It was found that as-sprayed sensor tubes have a lamellar structure.
After firing, the lamellar microstructure changed into granular-type (equiaxed grains) structure.

This was due to the PDMDAAC spatial structure, which was not complicate.
The modified bentonite structure had changed as the interplanar distance was different.
The raw bentonite structure was amorphous, the particle close together, the layer structure was not obvious.
The modified bentonite was a kind of space grid structure.
