Moreover, by adjusting the processing parameters, for example, the electrostatic spinning voltage, working distance and injection velocity of the solution, the electrostatic spinning method can easily control the structure of the fiber and further regulate drug loading’s efficiency, as well as can meet the requirements of the drug controlled release system[2].
The adding of PDLLA made the structure of the composite more complex, such as phase un-miscibility.

Most conventional adsorption uses activated carbon as an adsorbent, because it has a large surface area, micro structure, high adsorption capacity and high surface reactivity [10,11].
Furthermore, increasing temperature may produce a swelling effect within the internal structure of the adsorbent enabling large HA to penetrate further [1,21-24].

Essential differences are noticed in their structures: in the sample synthesized at nitrogen pressure of 0.1 atm the particles are characterized by evident faceting and triangular wedge-shaped sections which are likely to be the regions doped with nitrogen atoms.
It should be also noted that their size varies slightly within the range from 100 to 200 nm, and all of them possess approximately the same structure.

The durability of concrete structure was influenced greatly due to the action of freeze-thaw cycles.
The water conservancy projects in east-north, west-north of China, especially the concrete structures in the severe cold regions of east-north, all most 100% projects suffered from the damage of freeze-thaw cycles.
Durability of concrete the crossroad between chemistry and mechanics.

Some studies have proved that calcium phosphate ceramics with special structures could induce bone formation in soft tissue [2].
The chemistry of the ceramics was analyzed by X-ray diffraction (XRD).
The chemical composition and physical structure of ceramics are the major factors to initiate the osteoinduction of biomaterials and determine their osteoinductive capacity.

Distribution of Sulfur Forms in Low Temperature Pyrolysis of Coal Qiuxiang Yao1, a, Meili Du1, b, Shuili Wang1, Jing Liu1, Jianli Yang1, Haitao Shang1 1School of Chemistry and Chemical Engineering, Xi’an University of Science and Technology, Xi’an, Shaanxi 710054, China aqiuxiangy@yahoo.com.cn, bduml@xust.edu.cn Keywords: Low temperature pyrolysis; Sulfur forms; Distribution; Thiophenes Abstract.
Fig.4 Wiser bituminous coal model (2) Sulfur species in coal exist in the forms of organic compounds with aliphatic, aromatic or heterocyclic sulfur structures.
They tend to form H2S when heated or pyrolyzed, and sometimes are converted partly to the more stable compounds of heterocyclic structures [15].

The main reasons are that this product has lamellar structure to enhance its shielding protection effect, and micro-grade particle size is helpful to enlarge its active regions and improve its dispersibility.
The anticorrosive property of the title compound in alkyd paints is superior to that of commercial zinc phosphate because this product has lamellar structure to enhance its shielding protection effect, and micro-grade particle size is helpful to enlarge its active regions and improve its dispersibility.

ELECTROPHORETIC DEPOSITION OF NANOCRYSTALLINE BaTiO3 IN ETHANOL MEDIUM Aydin Dogan, Goktug Gunkaya, Ender Suvaci and Markus Niederberger* Materials Science and Engineering Department, Anadolu University, 26840 Eskisehir, Turkey *Max Planck Institute of Colloids and Interfaces, Colloid Chemistry, Research Campus Golm, 14424 Potsdam, Germany ABSTRACT Electrophoretic deposition technique is a versatile coating method.
By this method, altering the substrates morphology, structure, porosity as well as ion-dopants desired sensors can be tailored.
In this study the aim was not to prepare fully dense surfaces but create controlled porous network structure.

Fiber composite structures have become the most attractive candidate for civil engineering.
Glass fiber-reinforced composites replace the structure and shell body of the metal and pure plastic materials.
