FTIR and XRD characterized the structure of the PANI/Au composite microwires and microspheres.
However, when the molar ratio of Au to aniline was higher than 1.0 mg/mL, no sphere-like structures of PANI/Au composites were formed.
It was found that wire-like structures formed.
The molecular structure of the resulting PANI/Au composites was characterized by Fourier-transform infrared (FTIR) spectroscopy and X-Ray diffraction patterns (XRD).

Introduction Materials science research under strong gravitational field (1-10)×105 G (where 1G=9.8 m/s2) is still remained an unexplored area in physics whereas microgravitational environment has been excessively used in chemistry and life science research.
This series even exhibits metal-insulator transitions (MIT) due to the change in lattice structure [9,10].
Composition and structure were investigated with an electron probe microanalyzer (EPMA).
This formation of a graded structure is the consequence of the strong gravity acceleration on the specimen.

As shown in Fig.1, the fibers of the pretreated samples were visibly separated from the initially connected structure, and the pretreatment altered bamboo structure significantly.
In this study, the FTIR spectra were measured to study the differences in their chemical structure.
The band intensity is strongly influenced by the structures bordering the aromatic nuclei.
The SEM pictures of the pretreated samples indicated that the biomass structure is deformed and its fibers are exposed by the pretreatment.

[SiO4], the glass structure becomes loose and the density decreases [16].
(2) When the B2O3 content is too high, the boron-oxygen triangle [BO3] increases, the boron-oxygen tetrahedron [BO4] decreases, and the broken bonds in the glass structure increase, because the volume of the boron-oxygen tetrahedron [BO4] is larger than that of the silicon-oxygen tetrahedron [SiO4], this makes the glass structure loose

Infrared spectroscopy of alkali-free aluminoborosilicate glass structure.

The observed ground state structures for each pure element M are listed in Tables 1.
In this paper, we report the enthalpies of formation of Hafnium binary compounds HfM( M=Co, Ir, Os, Pt, Rh, Ru) at CsCl type structure (B2) with tow atoms at the primitive cell (0 0 0), (½½ ½).
Table 1: Stable crystal structures of pure elements at room temperature [29].
For each of these compounds, lattice parameters in its equilibrium structure (B2) and enthalpies of formation of compounds are calculated and compared with available data.

The structure and surface morphology of APS-MMT were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetry, scanning electron microscopy, and contact angle analysis.
A hybrid material prepared thus would exhibit a much higher chemical stability, as the guest species would be irreversibly bound to the structure.
Silylated MMT exhibits promising properties due to the combination of the pillared interlayer nanostructure with the rich surface chemistry of the functional groups that are covalently linked to the MMT surface.
The mean contact angle for the droplets on the surface of APS-MMT is 55.1°±0.3°, consistent with that for the amphiphilic modification of an inorganic structure[7].
The prolonged release of RSV was ascribed to the release of the intercalated RSV, whose diffusion was substantially retarded by the cross-linked structure of MMT[7, 16].

Polymer microcapsule is a kind of functional material with unique structure.
In recent years, polymer microcapsules have drawn broad attention in academic research and practical application owing to their unique structures and functions.
Hollow structure then occurs.
The morphologies and structures of PMMA microcapsules were determined by TEM on a Hitachi-7650 instrument (Japan).
It should be noted that some of these microcapsules have “hemisphere” or “bowl” structure, which resulting from the collapse in the process of sampling or testing.

The crystalline structure of the extracted cellulose fibers was observed by XRD.
XRD technique was used to evaluate the crystal structures of cellulose.
All samples revealed two crystalline peaks at 2 thetas around 16o and 23o, as representing for the cellulose I structure [12].
The sharpest crystalline peak of bleached fibers indicated the highest crystallinity due to the reduction of the amorphous structure of hemicellulose and lignin content.

Luteolin Imprinted Polymer with Selective Recognition and Adsorption Performance Ping-rui Menga , Liang-bo Li b Department of Chemistry, University of Jinan, Jinan, Shandong 250022, China aE-Mail:chm_mengpr@ujn.edu.cn, bE-Mail:chm_lilb@ujn.edu.cn Keywords: Molecular imprinting, Molecular recognition, Adsorbent, Luteolin Abstract.
The results showed that the cavities matching with the template molecules in size and structure were present in the LMIP.
Quercetin Scheme3.)was used as the competitive recognition molecule, which had a molecular structure similar to that of luteolin Scheme2.).
This is because the structure of the pores of the LMIP matched with the size and shape of the luteolin molecule.
In contrast, non-template molecules could not be recognized by functional groups because their structures and size did not match with the cavities of the LMIP.

The antibacterial materials are divided into organic group and inorganic group according to their structure.
From Fig.3 (a), we can see that there are many pores with the size of tens of nanometer in the structure of raw Medical stone.
After containing copper and Zinc ions, as shown in Fig.3 (b), the structure of the antibacterial agent, relatively speaking, exhibits a significant decrease in pore size.
The SEM result indicates that Cu 2+ and Zn 2+ had been entered the structure of Medical stone by the role of ion-exchange or adsorption.
