To develop high performance superconducting material, we must control the nano-scale structure.
These two results are quite different, and the differences may be related to the different lattice structure of two kinds of materials.
Based on this idea, especially in recent years, this idea has been widely used in the field of nanomaterials synthesis under the circumstance of the rapid development of bionics, colloid chemistry and surface science, physical, chemistry and other subjects.
Activated monomer polymerizes to form gelatin and then form gelatin with certain space structures.
This method plays an important role in soft chemistry and it is widely used in the preparation of nanoparticles, the most common of which is the use of alkoxide hydrolysis and organic complexation to get sol precursor.

Finally, 500 ps production run has been performed for analysis to obtain the structures and diffusion properties.

Thermal decomposition synthesis of MoO3 for application in electrochemical supercapacitors Xiaoping Zhou1, a, Lin Ma1, b, Xuyao Xu1 and Zongcai Feng1, c 1Institute of Physical Chemistry, School of Chemistry Science and Technology, Zhanjiang Normal University, Zhanjiang 524048, P R China azhouxp2014@126.com, bmalin3722@126.com, cfengzongcai921@163.com Keywords: Supercapacitors, MoO3, Specific capacitance Abstract.
The structure and surface morphology of the as-prepared MoO3 was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
Transiton metal oxides with layered structures are attractive materials for electrochemical supercapacitors due to their ability to intercalate ions in a wide range of sites [3-5].
The structure and surface morphology of the MoO3 was characterized by XRD, SEM.
The main diffraction peaks reflection agree with standard powder diffraction patterns of MoO3 with orthorhombic structure (JCPDS no.05-0508).

Cobalt Doped ZnO Nanorods Fabricated by Chemical Bath Deposition Technique Parameswar Hari1, a, Jared Seay2,b, Kevin Farmer3,c and Ken Roberts4,d 1Department of Physics, Keplinger Hall, 800 South Tucker Dr, Tulsa Oklahoma, USA 2Department of Physics, Keplinger Hall, 800 South Tucker Dr, Tulsa Oklahoma, USA 3Department of Chemistry, Keplinger Hall, 800 South Tucker Dr, Tulsa Oklahoma, USA 4Department of Chemistry, Keplinger Hall, 800 South Tucker Dr, Tulsa Oklahoma, USA ahari@utulsa.edu, bJared-seay@utulsa.edu, ckevin-afarmer@utulsa.edu, dkproberts@utulsa.edu Keywords: ZnO nanorods, Cobalt doping, Photoluminescence, Raman spectroscopy Abstract.
We will discuss details of ZnO-Cobalt structures using Raman spectroscopy on cobalt doped ZnO nanorod samples of 1 -20% doping concentration.
Cobalt atoms can also be introduced into ZnO with very little induced strain in the host ZnO lattice structure due to the similar ionic radii of Co2+ (58 pm) and Zn2+ (60 pm) ions.
Higher Co doping concentrations are introducing a significant number of defects into the ZnO wurtzite structure, as can be seen by the suppression of the UV emission peak at 20 at.% Co.

This article reviewed the research results of the microbiology diversity, community structure and distribution, function gene and special microbial carbon metabolism passway in the hot spring of YNP.
Their ecology processes influence almost the elements in the chemistry periodic table[1,2].
Principle and process of travertine deposition Springs emitting supersaturated water with respect to CaCO3 have the potential to create travertine structures that dramatically alter stream morphology.
These famous travertine geomorphological structures included the Mammoth hot spring of Yellowstone National Park, USA, Huanglong national scenic of Sichuan, China, Cascadas de Agua Azul of Mexco, and Havasu Creek of Supai reservation, Arizona, USA.

Also, in order to study the relationship between the exchange capacity and the pore water chemistry, pH measurements was performed on cured samples.
The CECp is defined as the cation exchange capacity (CEC) attributed to the permanent charges of the clay structure.
It was also clear that as the amount of stabilizer increased, the variation in pH value were more significant implying that the stabilizer content was predominantly controlling the pore water chemistry.
Whereas, the longer term strength development for acid treated samples was likely to be more reliant upon the slow weathering action of acid on the soil structure and the subsequent formation of reaction products.

The nanotubular structure of TiO2 was characterized by scanning electron microscope (SEM).
Furthermore, their tubular structures have prompted research into the physical and chemical properties of molecules confined in their inner nanospaces and eventually may lead to the mimicking of biological channels[3].Carbon nanotubes have been well studied since Iijima first discovered in 1991[4].
The studies developed an elecreochemical basis for the investigation of protein structure and mechanisms of redox transformations of protein molecules.
Actrully, enzymes adsorbed on the electrode surface are easy to loss their electrochemical activities and bioactivities and the active sites of enzyme are deeply buried in the molecules, so it is difficult to obtain the direct chemistry reaction of enzymes.

The structure of PANI prepared by this method was characterized by Fourier transform infrared spectroscopy (FT-IR), transmission electron microscope (TEM).
The morphology of the products was characterized by transmission electron microscope (TEM, Tecnai G2 F20).The electrochemistry performance of PANI was measured by electricity chemistry workstation (CHI600B).
The migration of two uinoid structure peaks was mainly because the SO32- had strong electronegativity.
Between these two redox peaks, there were two couples of peaks stemming from the transition of quinonimine structure.
