The purity and structure of the intermediate were also measured by GC-MS.
The IR spectra and 1H NMR spectrum were in agreement with the proposed structures.
The structures of the synthesized intermediate and final products were determined by means of IR and 1H NMR.

It is possible that this simple process can be carried out in fabrication of more complicated structures, which are potentially useful in many applications such as nanoelectronic, photonic and SERS.
For the purpose, various self-assembly techniques have been developed to assembly several kinds of nanowires into regular structures [5-7].

The ATRP of N-isopropylacrylamide (NIPAM) was carried out in DMF/water at 60 °C to afford a novel linear end-functionalized poly(N-isopropylacrylamide) with acetylated β-CD (AcCD-PNIPAM) and the structures of the products were characterized.
Cyclodextrins (CDs) have a specific steric structure of truncated conical shape and possess a hydrophilic exterior surface and a hydrophobic interior cavity, which can accommodate a variety of molecules as guests [3-8].

The structure of the novel borate ester formed by reacting boric acid and lauryl alcohol and with diethanol amine was established by 11B, 1H NMR spectroscopy and IR spectrum.
From 1H NMR spectroscopy, the detection of a 3.65ppm shows existence of -B-OCH2-.The structure of -N(CH2CH2O)2B group is supported by the observation of two resonances for the at δ H=2.82ppm and 11.02ppm in the 11B NMR spectrum in accordance with the result of Fig.2. 6 4 2 0 chemical shifts[ppm] 3.923.71 3.65 2.82 1.55 1.26 0.88 75 50 25 0 -25 -50 Chemical shifts[ppm] 11.02 Fig.3 The 1H-NMR of LNB Fig.4 The 11B-NMR of LNB Hydrolytic stability Table 1 Hydrolytic stability in paraffin oil of the borate esters Borate esters Code Hydrolytic stability(h) C12H25OB(OH)2 LB <12h HN (CH2CH2O)2BOC12H25 LNB >144h The experimental results for hydrolytic stability of borate esters are shown in Table 1.

A novel β-cyclodextrin (β-CD) grafted titanium dioxide (TiO2/β-CD) was synthesized through photo-induced self assembly methods, and its structure was characterized.
As presented in Fig. 3, there was no change in the lattice structure of TiO2 after β-CD modification.

Effect of Selenium on Structure and Electrical Property for Bi0.4Sb1.6Se3xTe3(1-x) Novel Hexagonal Rods A.
The X-ray diffraction results indicate that the powders (0.0≤x≤0.8) can be indexed as the rhombohedral phase, whereas the sample with x=1.0 has an orthorhombic phase structure.
XRD experiments were carried out to determine the structure of the powder samples, and the results are shown in Figs. 2(a) and (b).
The alloying of Se in Bi0.4Sb1.6Te3 changed the crystal structure from rhombohedral (0.0≤x≤0.8) to orthorhombic (x=1.0).

There was no indication of porous structure with sintering time of 1h, while clear and ordered porous structure could be seen in figure 3(b) with sintering time of 6h.
Though the sample sintered for 12h showed porous structure as a whole (figure 3(c)), ordered structure had been disrupted and ZnO crystal rods were formed.
As a result, the ordered structure of inverse opal was destroyed by long ZnO crystal rods.
Well-ordered porous structure was observed when 12ml HCl was used.
