Carbon can bond in different ways to construct structures with completely different properties.
Conclusion The near infrared spectroscopy provides information on the adsorption of water molecules by surfaces containing polar groups and can be employed to deduce the chemical structure of the sample surface.

Different ceramics have been produced by high-energy milling, which present homogeneous composition and structure [7-9].
It well known that the Ti presents an atomic radium of 1.45 Å (ionic and covalent radii of 1.32 and 0.60 Å, respectively) while that the Al is 1.43 Å (ionic and covalent radii of 1.25 and 0.45 Å, respectively), indicating that the Al atoms can be dissolved into the TiO2 structure with partial occupation of Ti sites and providing a moderate distortion at the TiO2 lattice.

High-temperature oxidation behavior of Cu-20Ni-75Co alloy Zhongqiu Cao, Fengchun Li and Ying Shen College of Chemistry and Life Science, Shenyang Normal University, Huanghe Northern Street 253, Shenyang, Liaoning Province, China Email: caozhongqiu6508@sina.com Keywords: Cu-Ni-Co alloy; adding Ni; high-temperature oxidation Abstract.
On the contrary, it formed complex oxide scale structure.
The general structure of the scales is rather uniform in planes parallel to the alloy surface, while their composition changes with distance from the alloy/scale interface.

HAp with the stoichiometric formula of Ca10(PO4)6(OH2) has similarity in structure and morphology to human bone [3] and its biocompatible nature making it is suitable for biomedical applications [4].
As the temperature of calcination increase, the size of HAp structures begin to increase and it was further increased until temperature 1100 °C.

Natural starch exists in a granular structure with about 15-45% crystallinity.
Conclusions As enforcement, sisal fiber could effectively improve the tensile strength, elastic modulus and thermal stability of TPS, because of their similarly chemical structure, making a good adhesion between starch and fiber.

In this last case, the pressure of the high concentrations of interstitials (fission products) produced by elastic collisions would cause a denser material, thus a more symmetrical structure of zirconia.
The development of a wrinkled surface can be observed at the interface between the pellet and the corrosion layer, linked with the high burn-up structure at the edge of the pellet.
