Synthesis and characterization of LiNi0.4Co0.2Mn0.4O2 cathode material via urea co-precipitation method ZHONG Sheng-kui1,2,a, XU Yue-bin1,b, LI Yan-wei1,c, LIU Chang-jiu1,d ,LI Yan-hong3,e (1 College of Chemistry and Bioengineering, Guilin University of Technology, Guilin 541004, P.
The XRD, SEM and electrochemical measurements were used to examine the structure,morphology and electrochemical characteristics, respectively.
It’s hard to prepare LiNiO2 and the crystal structure will change during the charge-discharge process, resulting in much attenuation of its capacity[4].
LiMnO2 with layered structure has high theoretical specific capacity of 285 mAh·g-1.
However, during the process of charging and discharging, the structure easily change to the spinel structure, resulting in capacity’s fast attenuation[5].

Structure and Properties of Irradiation Crosslinked UHMWPE Han Lin1,a, Limin Dong2,b *, Chen Wang1, Tongxiang Liang2, Jiemo Tian2 1State Key Lab of New Ceramics and Fine Processing, Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing 100084, China 2Beijing Key Lab of Fine Ceramics, Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing 100084, China a492174178@qq.com, bdonglm@mail.tsinghua.edu.cn Keywords: UHMWPE, γ-rays, cross-link, mechanical properties Abstract.
To analyze the structural change of UHMWPE, the author used Fourier infrared spectrum analyzer to test the nature of the samples and internal chemical combination, to analyze the samples of crosslinking, and to study the effect of structure on performance.
After irradiation, Macromolecular chain was interrupted into active free radicals; these free radicals form crosslinking with each other, which changed the UHMWPE to 3D mesh structure.
Conclusions With the increase of radiation doze, the impact properties decline gradually; which means UHMWPE become harder and more brittle.We can see that, through the infrared spectrum, chain structure of the material are destroyed and reform the mesh structure.

Intimate Heterojunction Structure between Titania and Polythiocyanogen and Its Photovoltaic Effect Min-Hye Kima , Ji Man Kim b and Young-Uk Kwon c,* Department of Chemistry and BK-21 School of Molecular Science, Sungkyunkwan University, Suwon 440-746, Korea a morning204@skku.edu, bjimankim@skku.edu, cywkwon@skku.edu Keywords: mesoporous titania, electrodeposition, conducting polymer, heterojunction, solar cell, thin film Abstract A heterojunction structure between a cubic structured mesoporous titania thin film and polythiocyanogen inside the pores was prepared by electrodeposition technique.
In addition, this heterojunction structure was fabricated into a photovoltaic cell and the cell performance was tested.
This appears to match well with the electronic structure of titania for conversion of photon into electricity.

The 31P MAS NMR and Raman spectra show that at all glass series with the replacement of PbO by Li2O the ratio of Q 2/Q 1 units, present in the structure, slightly increase.
Our recent studies of K2O-PbO-B2O3-P2O5 [1] and Na2O-PbO-B2O3-P2O5 [2] glasses revealed substantial changes in their structure and properties with compositional changes.
The reason for the decrease of VM is the gradual crosslinking of network structure by BO4 and BO3 borate groups interconnecting phosphate chains.
This shift gives evidence for the dominant function of Q 2 groups in the structure of 50Li2O-10B2O3- 40P2O5.glass.
