Amongst the family of conducting polymers, polyaniline is unique due to ease of synthesis, environmental stability, simple doping/dedoping chemistry and relatively inexpensive cost.
As a result, polyaniline can distribute stably in polyaniline membrane to produce stable structure and preferable performance.
It has been widely investigated and has major application in chemistry, physics, material science and engineering.
The aim of this study is to investigate the performance and structure of polymeric membrane when blended with PANI nanoparticles.
PANI can exist in blend membranes stably, thus produce membrane with stable structure and preferable performance.

Using BP neural network method, we calculate and analyze the molecular structure of aromatic hydrocarbons.
Nowadays, QSAR is widely used in fields of Pharmaceutical Chemistry [3], Food Chemistry [4], Environmental Chemistry [5] and Toxicology [6].
We also analyze the effect of the space structure and the electronic structure of aromatic hydrocarbons molecular on its toxicity.
We construct the BP neutral network model with the structure of 4-2-1.

By physical method, the oxides powder with diameter of several nanometers could be obtained, and the nano particles have large and clean surfaces, but broad particle size distribution and serious accumulation. 2.2 Chemical synthesis method These methods include wet chemistry methods and dry chemistry methods.
Dry chemistry methods include self–propagation high–temperature synthesis (SHS) method, chemical vapor deposition (CVD)method, solid state reaction method, and so on.
Compared with the dry chemistry methods, there are more wet chemistry methods among synthesis of nano materials, such as coprecipitation method, sol-gel method, metal alkoxides hydrolysis method, spray pyrolysis method, hydrothermal method, as well as the recently developed sonochemical reaction method, microemulsion method, template method and self-assembly method.
This metastable rocksalt structure, which had been observed previously only under high pressure was observed.
Because of its stable conjugate structure, benzene is a good candidate in solvothermal synthesis.

It has been identified that a spherical, fcc structure, 100nm β-Co powders was synthesized. 1.
Introduction Cobalt powders have special structures and properties as others transition metals, from beginning of twentieth century, many material scientists had paid high attention to it.
Cobalt has two crystal structures, β-Co (fcc) and α-Co (hcp).
So it can be concluded that the final products using this study were fcc structure β-Co powders. it can be seen tha the grain size increased obviously at 550℃.

Syntheses and Characterizations of New Eu-Ce Codoped LaSrSiO3N Phosphors for LEDs Decai Huanga, Youfu Zhoub*, Chao Quan and Wentao Xu Key Laboratory of Optoelectronic Materials Chemistry and Physics, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Fuzhou 350002, P.
The structures of these discovered phosphors were non-existent in any of the commonly available crystallographic databases such as that of the International Centre for Diffraction Data (ICDD) and the Inorganic Crystal Structure Database (ICSD).
The starting materials were high purity SrCO3 (Aladdin Chemistry, 99.99%), α-Si3N4 (Aladdin Chemistry, 99.9%), SiO2 (Sinopharm Chemical Reagent, 99.5%), La2O3 (Aladdin Chemistry, 99.99%), CeO2 (Aladdin Chemistry, 99.99%) and Eu2O3 (Aladdin Chemistry, 99.99%).
As shown in the XRD spectra of Fig.1, the LaSrSiO3N: (Ce3+, Eu2+) phosphors have a Pnma orthorhombic structure that is similar to that of LaEuSiO3N, and have the same crystal structure as that of SrSiO4 [13].
By virtue of having the same crystal structure, even if La-N moieties are substituted for some of the Sr-O in SrSiO4, it may be assumed that the crystal structure is stable.
