Secondly, changing the reaction time, the structure and size of graphene oxide were analyzed using X-ray diffraction(XRD) and Malvern Zeta-Size Analyzer, and the effects of different reaction conditions on the XRD patterns of graphene oxide were discussed.
Eda believes that, graphene oxide has sp3/sp2 hybrid two- dimensional network structure, this unique atomic and electronic structure afford some conditions for its new performance, and the isolated sp2 clusters existing in the carbon-oxygen sp3 matrix lead to electron-hole pairs positioned, so as to promote the radiation of small clusters restructure [12].
This results show that the extension of the medium temperature reaction times is favor to obtain the graphene oxide with good structure.

These structures are characterized also with paramagnetic properties- by method of ESR the free radicals are discovered in the transformed regions of polymers.
First of all these changes are expressed in excitation of macromolecules with consequent formation of free radicals and the systems of conjugated double bonds with linear or cyclic structures [5,6].

When Shape memory alloy (SMA) wires are embedded in the composite structure with a specific volume fraction, the properties of the resulting hybrid composite structure, which is called SMA-reinforced composite structure, will be reinforced.
It has been proved that SMA wires embedded in the composite structure with a specific volume fraction may reinforce the structure [1].
The resulting hybrid composite structure is called SMA-reinforced composite structure.
It can be used to sense information of surrounding product and environment such as temperature, moisture, optics, chemistry [4,5,6], and send this state information to the counting unit wirelessly.
The structure of the system is shown in Fig. 1.

Preparation of a novel red long lasting phosphorescent material CaAl2Si2O8:Mn2+ and investigation of its luminescent properties Bisang Chen Zishan Zheng* Yanmei Lin Guoliang Chen Liang Zhou Hongxu Guo Lingfeng Huang Department of Chemistry & Environmental Science, Zhangzhou Normal University, Zhangzhou 36300, Fujian, P.R.China Corresponding author: Prof.
X-ray diffractometer(XRD) and fluorescence spectrometer were used to characterize the structure and photoluminescence of the persistent phosphors, respectively.
The main diffraction peaks are all consistent with the standard data for CaAl2Si2O8 spinel phase (PDF 41-1486), indicating that the doped ion Mn2+ do not cause any significant change in the host structure.

Ti-based I-phase alloy was considered as one of the most promising hydrogen storage materials due to thermodynamical stability, suitable chemistry affinity and low cost.
The local structures of Ti-based I-phase alloys are believed to be related to the Bergman two-shell atomic cluster, which contains 20 tetrahedral interstitials within its inner shell, 120 between its inner and outer shells [11].
Ti-based alloys containing I-phase have more advantages compared with other icosahedral quasicrystalline alloys, such as, thermodynamical stability and suitable chemistry affinity [6-9].
Higher discharge capacity may be ascribed to the composite structure.
It is pomising that the discharge capacity of I-phase composite alloy electrode are higher than that of commercial AB5 alloy electrode due to particular quasicrystalline structure containing lots of octahedral site hydrogen atom prefers to.
