In particular, the effect of La3+ and Al3+ codoping on the structure and electrochemical performance has been studied in detail.
The broad and diffuse peak, namely featureless appearance, is typical of amorphous structure.
To obtain further information on the structure of the prepared nickel hydroxides, Raman spectroscopy was performed.
This peak is related to the number of structure defects, include proton hole and nickel hole [6].

They have an open structure of three-dimensional tetrahedral unitsgenerating a network of pores and cavities that have molecular dimensions [2].
Therefore, to obtain zeolites composed of a single phase and with an organized structure, several strategies are used.
The energy released during combustion can affect the structure of the formed zeolite [8].

The composite polymer electrolyte materials has become an intersection of many disciplines including materials science, chemistry, physics, and the content may lead to the field of new energy materials, in particular, is a new technological revolution in the field of battery materials, which study of the problem will continue and in-depth.
Introduction Polymer electrolyte originated in 1973, PV Wright and reported that the poly (ethylene oxide) (PEO) polymer and alkali metal ions to form solid solutions with ionic conductivity, the structure of the PEO/LiClO4 electrolyte as shown in Figure1.2 as shown in.
PEO with helical structure of the oxygen atom with the lithium cation binding, the anion balance of the chain structure of polymer and LiClO4 can form different complexes.
X-ray diffraction (XRD) in the polymer electrolytes are widely used, there is some intrinsic link between crystal structure and diffraction pattern can be solved by analyzing the diffraction pattern of the phase composition of the polymer electrolyte, the degree of crystallinity and crystal a range of issues related to the structure.
Diffraction peaks characteristic of the sample by the XRD technique can be for the analysis of different filler content on the crystal structure and conductivity of great significance.

The structure of Pd-Au/4A zeolite catalyst was characterized by a combination of atomic absorption spectrometry (AAS), scanning electron microscopy (SEM) and X-ray diffraction (XRD).The AAS testing showed that Pd and Au supported rate were increased up to the maximum 93.88% and 90.22% respectively at the ratio of Pd/Au=1.16.
It is the aim of this work to prepare Pd-Au/4A zeolite catalyst by using Pd-Au bimetallic as active components and 4A zeolite as carrier and to describe the structure of Pd-Au/4A zeolite catalyst by AAS, SEM and XRD; in addition, the catalytic activity of the Pd-Au /4A zeolite catalyst was determined in vinyl acetate synthesis.

Effect of Heat treatment on the Structure and Morphology of Amorphous Steel Produced using Spray Metal Forming A.
However, the heat treatment at 700 o C showed some effect on the crystallization of the structure.
The chemistries of the spray metal formed alloy (DAR -35) were determined by a commercial vendor.
The as-sprayed chemistry was near the starting ingot / material nominal composition.
In addition, it appears that the fine structure follows a preferred crystallographic orientation.

The effects of temperature and time of hytrothermol process, and calcination temperature on the structure had been investigated via XRD,SEM,TEM.The results indicated it will be better hythrothermol treating 20h at 120℃ and then heat-treating 4h at 400℃.
Fig.9 the small angle XRD diffraction illustrates: there is a single diffraction peak（2θ=2~3°）exist in low angle area after calcination,indicating that the disordered mesoporous structure in nano particle as the calcination temperature rise up so that mesoporous peak move to wide angle,that is,value d in the equation cut down with the increasing temperature because of the further regularization of structure of mesoporous led by granulation of aperture and grown-up particle.It describes that appropriate calcination temperature will lift the order of structure of mesoporous.But mesoporous peak disappeared when tempertature heat up to 600℃,because the damage to the structure of mesoporous led by high temperature incineratiion results in turning TiO2 into crystal totally,and the weak interaction between grains caused by larger crystal size.It will result in the collapse in pore wall while they are not firm enough to support mesoporous.In this case, 600℃ is not desirable.
(1)The better suggestion to prepare anatase TiO2 microsphere material with structure of mesoporous is template removal and thermal treatment by 120℃ hydrothermal reaction for 20h and 400℃ calcination for 4h

The chemistry of the PEI-g-lentinan obtained were characterized.
Further studies have shown that the transfection efficiency and cytotoxicity of PEI/DNA formulations are highly dependent on the macromolecular structure (branched versus linear) and molecular weight of PEI [1], e.g., PEI (5 K) was reported to have lower cytotoxicity and show DNA transfection efficiency comparable to PEI (25 K)in vitro, but no in vivo results were reported [2].

Obviously, the smaller particle size are received on β compared with mordenite which may relate to different zeolitic structures.
It is clearly to see from the XRD patterns that the ultrasonic wash has little effect on the framework structure of the mordenite.
This is probably due to the differences of molecular sieves’ framework structures in topology and zeolite crystal dimensions.
(3) The molecular sieves maintain the intact structures after loading.
