Low-temperature (LT) scanning tunneling microscopy (STM) can resolve both, the local atomic structure and the superimposed charge density modulation.
Fig. 1 The basic structure of NbSe3 [11].
Subsurface contributions to the LT STM images are of crucial importance in cases like NbSe3 and the related structures.
Finally, the origin of the unusual CDW ordering in NbSe3 and the few related compounds is in their specific structures.

Facile Solid State Method Route Synthesis and Enhance Visible Light Activities of BiVO4 by Doping Co Chen Haifeng, Hu Jingling and Xu Bing Department of Materials & Chemistry, Huzhou Teachers College, P.
Crystal structures of these samples were characterized by X-ray diffraction (XRD).
The photocatalytic property of BiVO4 was strongly depended on its crystal structure.
Among these structures, scheelite-monoclinic phase has higher photocatalytic effect.
Different structures could be obtained by distinct preparation.

After modification, the silica aerogels have a spongy nano porous structure with larger pore and skeleton sizes.
This different structure can attribute to the condensation reaction of modification agent TMCS and silanol group on the silica surface.
Moreover, the controllable structure and hydrophobic properties of silica aerogels result in wilder applications.
The large oil adsorptive capacity of aerogels can be explained from surface chemistry.
The result shows that surface modification plays an important part on chemical properties and structures of silica aerogels.

The SEM micrographs showed the visual structure changes of this progress.
The pretreatment process breaks the structure of the raw biomass, destroys the amorphous region so as to increase the activity of enzyme.
The absorption bands in 1431cm-1 and 1164cm-1 are the characterized absorption peaks of cellulose structure, there are no much differences between the raw material and treated materials, which means thatalkaline solution has a little impact on the cellulose structure.
It makes a significant change in cellulose region, such as degree of crystallinity, microcrystalline size and crystal transfer.SEM micrographs offer visual expressions including the structure of raw material and changes of different pretreatments.

For anatase and rutile structure, they are required to be potentially active materials for various applications.
A slight shift of the peak position indicates the change of structure with incorporation of Co on anatase lattice of TiO2.
The crystal structure of undoped sample showed the presence of tetragonal anatase phase of TiO2.
However, the crystallinity of Co-doped TiO2 samples is obstructed and deterioration of local structure of TiO2 was existed.

The microstructure observation for the Nb-35Ti-20Al-10Cr/Al2O3 composites demonstrated that it was still retained the layer structure characteristics of the preform.
After the porous Al2O3 ceramic body infiltrated with Nb-35Ti-20Al-10Cr alloy, the spatial structure of the composite is still retained the layer structure characteristics of the preform.
Therefore, the composite structure can be designed by adjusting the slurry concentration, the cooling rate, the sintering temperature and other processing parameters.
The Nb-35Ti-20Al-10Cr/Al2O3 composites prepared by pressureless infiltration was retained the layer structure characteristics of the preform.
