The results show that the TiO2 thin film is in monolayer with nanometer level, the deposition is the anatase structure.
Special physical chemical properties can be attained by a kind of specific group is adhibitted into interspace of the alkyl chains because the molecular structure and surface structure of group can be selected.
The TiO2 thin film calcined at 723 K for 2 h constructs with copoint or coedge tetrahedrons (Fig. 6) that its structure is analogous to that of anatase.
This characteristic can be explained by the structure of silane coupler [15].

In the structure of sepiolite, three forms of water exist, namely: adsorbed water, crystal water and hydroxyl water.
However, desorption of crystal water does not destroy the framework of sepiolite structure completely.

The chemical structure of the OACh was characterized by FT-IR, 1H and 13C NMR.
Some progresses have been reported in the preparation of water-soluble chitosan derivatives, such as N-lauryl-N-methylene phosphonic chitosan, N-carboxymethylated chitosan, N-acetylchitosan, N-trimethyl chitosan chloride, N-methylated chitosans and N-phthaloylcarboxymethylchitosan. [3-6] As reported, long-chain fatty acids, including the oleic acid, linoleic acid and palmitic acid, have been used as a hydrophobic moiety for the formation of chitosan micelles.[7] Chitosan fatty acid conjugates can be formed the nanomicelles with a hydrophobic core and hydrophilic shell structure in aqueous solution.
The structure of oleoyl acetyl chitosan was characterized by FT-IR and NMR.

The effect of the mechanical alloying and nitriding time on the structure and properties of Sm-Fe-N alloys were studied in the course of the research.
The investigation of the obtained alloys structure was carried out using the Mira Tescan scanning electron microscope.
In reference with the above, it should be noted that mechanical alloying modes were selected to obtain a powder with a partially amorphous structure (the shaded area).
It allowed getting almost a single-phase fine-grained structure Sm2Fe17 (Fig. 2b).

More importantly, the rich intercalation chemistry of clay silicate can be used to facilitate exfoliation of silicate nanolayers into the polymer network.
The bulk structure of ENR-50 containing 3% MMT shows pore structure with aerogel appearance where the nanoclays have partially interacted with the ENR-50.
In the hybrid structure containing 3% MMT, a similar structure is observed, however the extent of exfoliation differs.

- Polymer nanocomposites are materials in which at least one of the phases has at least one dimension of the order of nanometers, or structures having nano-scale repeat distances between the different phases that make up the material.
Several researchers in fields of Polymer physic, chemistry and engineering show great interest for developing high-performance of polymer micro and nanocomposites systems i.e. : improved barrier properties, fire resistance, strength… The Conference on Multiphase Polymers and Polymer Composites Systems: Macro to Nano Scales was organized at Paris-Est Créteil University, France on June 7-10, 2011.
The content of the conference was unique since a particular attention was focused to the different length scales (macro, micro and nano) relevant for a deep understanding of the structure-property relationships of nanocomposite materials.

The special structures and properties of boron and boron-rich borides are attributed to their original three-center electron-deficient bonds.
It is useful and meaningful to investigate the effects of sputtering power on the structure and properties of B films.
Influence of sputtering power on structure, surface topography and chemical composition of B films were studied and discussed.

The outer layer presents a porous blocky structure for Clinocardium californiense shell and a layered structure for Veined rapa whelk shell.
In 1972, Taylor and Layman [1] divided the microstructures of shells into 8 main kinds with individual characteristics, including simple prismatic structure, composite prismatic structure, sheet nacreous structure, lenticular nacreous structure, foliated structure, crossed-lamellar structure, complex crossed-lamellar structure and homogeneous structure.
In short, the inner and middle layers of both shells exhibit a cross-lamellar structure, but there are some differences in the morphology and dimension between those structures, whereas the major difference in the structure of these two shells comes from the outer layer, i.e., a porous and blocky structure for Clinocardium californiense shell, and a layered structure for Veined rapa whelk shell.
(1) Both shells present a hierarchical structure, and their inner and middle layers exhibit cross-lamellar structures.
