The bond between two atomics of carbon is modeled as beam structure.
Fig. 2 shows the three possible orientations of CNTs structure.
Three possible structure orientation of SWCNTs. 3.
Atomistic vs Continuum To establish a linkage between the microscopic chemistry and the macroscopic mechanics, covalent bonds between carbon atoms is represented by a force filed as a function of bond lengths and bond angles.

As an example, poly(glycerol-succinic) acid dendrimers are based on polyester structures.
Chemical formula and structure of the magnetite and maghemite iron oxides [167].
As previously mentioned, CNTs are one of the most interesting compounds in materials science and medicinal chemistry, but they are insoluble and hardly dispersible in any type of organic solvent or aqueous solution, which makes their use in biology or medicinal chemistry a possible problem.
This research area joins chemistry, materials science and biology.

These include bath chemistry, particle characterization, operating conditions, also the thickness of the coating and particle size.
The SEM micrograph analyses of in-situ deposited structure are shown in Fig. 10.
Ferrite containing Ba, Za, Co, Fe and having a hexagonal structure produces large microwave magnetic losses.
The structure of the EL coatings “as coated” was amorphous.
Coatings attain an equilibrium crystalline structure of Ni and Ni3P after heat-treatment (4000C, 1h).

The results suggested that the SAM can
induce the formation of the nano-HA coating with a network and microporous structure.
The crystal structure of the coatings on Ti surface after calcium phosphate deposition was characterized using thin film X-ray diffraction (TF-XRD, X'Pert Pro MPD, Philips, Netherlands).
After the Ti plates with HDA-SAM were immerse in SBF for 7 days, typical globular Ca-P precipitates with a network and micropours structure formed on the Ti surface as shown in Fig.6.
The HDA-SAM on the Ti surface can induce Ca-P nucleating to form the nano-HA coating with network and microporous structure which is helpful for growth of bone tissue.

Their identical properties such as high surface porosity and perfectly patterned pore structure, which is combined with mechanical strength make them ideal for many applications such as microorganism removal, blood filtration and protein purification.
Material and Methods 2.1 Fabrication of Polymeric Micro/nanofilters For fabrication of polymeric microfilters, we employed SU-8 (MicroChem corp., Newton, MA) which is a high contrast, epoxy-based photo-resist with suitable chemical and mechanical properties, capable of developing thick and multi-level micro-structures in multiple photo-lithographic steps [9-13].
SEM image of the membrane′s structure is shown in figure 2(c).
The high-resolution spectrum of the C 1s region in figure 5 (i.e. close-up) displays the changes in the surface chemistry after plasma O2 treatment.
It is expected that the fouling is primarily due to physical deposition of the clay particles on the membrane surfaces, which is not strongly dependent on the membrane surface chemistry [19].

Conclusions From the analytic results of the characteristics including FE-SEM, XRD and ESCA, it is known that the prepared TiO2/ITO photocatalysts have uniform structure, with grain size at about 20 nm, and the type of crystallization is mainly Anatase.
