There exists a huge number of unequivocally proven evidences in such direction in areas of science as different as heat conduction, magnetism, plasticity and solution chemistry to name just a few [6-13].
For this reasons, the physics and chemistry of nanometer-sized systems are commonly regarded as a new subject of scientific investigation [6-13].
Such particular regime of motion originates a dynamical structure showing a relatively high degree of order on the short range, but no order in the long range.

The results indicated that the as-prepared sample was in the keggin -type structure and the optimal parameters under the reaction conditions were as follows: 0.5 g of catalyst, reacted at 80 ◦C for 5 h.
The results indicated that the as-prepared sample was in the Keggin-type molecular structure of H3PW12O40 [6].
The SEM micrograph reveals that the HPW obtained was in the non-regular large bulk macro-structure (Fig. 2).
The bulk structure was responsible for the low surface area (1 m2/g). 31P NMR spectrum of as-prepared HPW displayed a characteristic peak at -14.75 ppm, which was consistent with that of H3PW12O40 reported in literature [7].
The results indicated that the prepared sample was in the keggin-type structure, and the optimal reaction parameters were as follows: 0.5 g of HPW, reacted at 80 ◦C for 5 h.

The structure of MWNT/PAN composite film was characterized by WAXD and FT-IR.
Fig. 2 WAXD patterns of MWNT , PAN, MWNT/PAN composites From Fig.2 it can be seen that the crystalline characteristic peak of PAN at 2θ=17° are maintained in all composites, which means that low content MWNT does not affect the packing structure of PAN.
It is observed that the rare MWNT phase dispersed as network structure embodying the enriched PAN phase.
The network structure of MWNT in PAN matrix should be responsible to flame retardant performance and high conductivity.

XRD patterns show that the Gd-doped film maintains the hexagonal wurtzite structure with the (002) preferred c-axis orientation.
The quenching of UV emissions in AlN: Tm appears related to the thermal activation of the excitons bound to the RE structure isovalent charge trap.
The crystal structure of the product can be determined as hexagonal AlN and is in good agreement with that reported in ICDD-PDF65-0891, indicating a c-axis texture normal to the film plane.
Secondly, from the XRD patterns samples with different Gd concentration, only Gd concentration of 1.5% sample deposited on (111) shows clear AlN (002) peak, while other content doped samples are non-crystalline structure.
From the results, it was seen that the product shows hexagonal AlN crystal structure with Gd content of 1.5 at. %.

Investigation of Factors Influencing the Formation of Tungstate-Based Inorganic-Organic Hybrid Nanobelts/Nanotubes Deliang Chen and Yoshiyuki Sugahara Department of Applied Chemistry, School of Science and Engineering, Waseda University, Shinjuku-ku, Tokyo 169-8555, Japan ys6546@waseda.jp (Y.
Results and Discussion Typical Morphology and Structures.
It is clear that the filamentous structures are nanobelts, most of which are scrolled to make nanotubes with apparent diameters of 200−500 nm.
The high-resolution TEM image at point A of Fig. 1c is shown as Fig. 1d, which indicates that the nanobelt/nanotube has a lamellar structure along its length.
Its XRD pattern suggests that the interlayer distance of the lamellar structure is 2.59(1) nm.
