Considering these results, we hypothesized that low-dimensional structures could retard the electron-hole recombination, creating structures that show high activity for water splitting.
Therefore, we focused our research on a low-dimensional structure photocatalyst.
Summary Ln-doped CaZnGe2O6 was synthesized in a monoclinic structure by a solid-state reaction.

A highly porous fibrous structure is used as a case study.
Introduction X-ray computed tomography (CT) has become, over the past few years, a widespread and quite effective technique for estimating the internal structure of porous materials with complex architecture.
Following X-ray acquisition, the CT datasets were filter-backprojected to produce series of 2D gray-scale images (slices) of the network's internal structure.
Ultra high resolution scanners (synchrotrons or nano focus desktop CT scanners) are often required to accurately capture the fine microstructural characteristics of the aforementioned structures.

The structure of samples was identified by XRD analysis and the particle surface morphology was examined by SEM.
The results of XRD showed that the LiMnPO4 sample sintered at 700℃ for 20h had single ordered olivine structure.
At present, LiCoO2 with layered structure has been used as the main commercial positive material of lithium ion batteries.
It illustrates that all LiMnPO4 samples sintered at a temperature range from 600 to 800℃ were pure single phase with ordered olivine structure indexed by orthorhombic Pnmb.
The results illustrate that the LiMnPO4 samples sintered at 700℃ for 20h have single pure phase with ordered olivine structure and spherical particles distributed uniformly can be observed from the SEM pattern.

Physical characterization results obtained from various analytical techniques exhibit the well crystallinity phase of cubic β-In2S3 and wurtzite ZnO structure from XRD patterns.
However, In2S3 shows drastically low SBET value, thus when the In2S3 content, it might be the penetration of In2S3 into ZnO structure and collapse caused the destruction of ZnO hexagonal structure [16].
Herein, figure 3(c), the 35% IZ nanocomposite clearly shows that the coupling between ZnO and β-In2S3 nanoparticles are successful because of embedded ZnO particles into β-In2S3 structure [20].

The energy bands calculated for the k points along the high symmetry lines are shown in figure 2 The figure shows the energy band structure of CeS for two independent fully relativistic spin-polarized band structure calculations treated the 4f elec-trons as: (1) itinerant electrons using the local spin-density approximation assciated with the modified Becke-Johnson scheme and (2) partly localized using the LSDA+U approximation with Ueff=0.44 Bohrs.
In the LSDA+U band structure, the bands are slightly shifted upward, the amount of shift is due to the inclusion of the onsite Coulomb potential.
These compounds have valence band densities of states qualitatively similar to the band structures.

Synthesis and Characterization of Coordination Nano-material containing Vanadium with Helical Stracture Fengli Bei and Yanmei Li Key Laboratory for Soft Chemistry and Functional Materials (Nanjing University of Science and Technology), Ministry of Education, Nanjing 210094, China beifl@mail.njust.edu.cn Keywords: helical structure, 2,3-Diaminephenazine, vanadium pentoxide and coordination nanomaterials.
Recently, nanostructured V2O5 including nanotubes [11-12], nanobelts [13-14], nanorods [15], and nanowires [16,17] has been extensively investigated to improve its electrochemical properties, but few works about the helical structure of V2O5 has been reported.
The molecular structure of 2,3-DAP In the NMR spectrum, the peaks in 2.93 ppm, 2.76 ppm and 8.05 ppm, which are the solvent peaks, are seperately attributed to the 1H in two methyls and the 1H in formylphenyl of DMF.
The peak at small angle indicates that the complex is composed of layered structure, which is consistent with TEM images.
In a high resolution TEM (HRTEM) image taken from the edge of a nanoflakes in Figure 3b, it is clear that the microscopy of V2O5 nanohelixes is layered-structure.
