China agaojian@spu.edu.cn Keywords: nickelII complex, photosystem II, electrostatic interaction, supramolecular structure Abstract.
Adjacent complex link to each other via hydrogen bonds forming the three-dimensional supramolecular structure.
In order to mimic the manganese cluster, a series of manganese complexes have been synthesized,among which some crystal structures revealed the existence of significant electrostatic interaction between the Mn atom and the ligand(Nie et al., 2001;Hu et al., 2002; Liu & Xu, 2003).And the structure of the nickelII complex, provides a new example of this electrostatic interaction in an NiII complex.

All peaks can be well indexed based on the a-NaFeO2 structure, space group Rm.
This gives rise to disordering in the structure.
The structure contracts can prevent the transfer of Li ions.

Aqueous Synthesis of Highly Luminescent CdTe/CdS/ZnS Core-shell-shell Quantum Dots with Biocompatibility Huaiqing Huanga, Jinling Liu, Baofu Han and Shukun Xu*b Department of Chemistry, University of Northeast, Liaoning, Shenyang, 110819, China ahuanghuang97@sina.com, bxushukun46@126.com Keywords: CdTe/CdS/ZnS Core-Shell-Shell Quantum Dots, Aqueous Synthesis, Yeast, Biocompatibility.
These results also prove the formation of a CdTe/CdS/ZnS core-shell-shell structure rather than an alloy structure, otherwise the larger band gap energy of alloyed nanoparticles than that of bare CdTe QDs will lead to a blue shift in the absorption and PL spectra [7,8].
The CSS structure of the as-prepared CdTe/CdS/ZnS CSS QDs was proved by fluorescence spectra and TEM.

The surface of A-ACFs was also clean as that of V-ACF, indicating that the acid treatment introduced polar functional groups without severe destruction of surface structures.
In case of A-ACFs, it can be seen that pore structures are somewhat decreased around 8% (1308 m 2/g) and the fraction of micropore areas is also little bit diminished from 99.65 to 99.54% [5,6,11].
It was found that all ACFs showed higher adsorption capacity than that of coconut-based ACs, which is attributed to the micropore structures in the ACFs.

Self-assembly of Alkali Lignin in Tetrahydrofuran Hao Li1a, Yonghong Deng2b, Kai Huang3c 1,2,3,4School of Chemistry & Chemical Engineering, South China University of Technology, 381 Wushan Road, Guangzhou, 510640, China alihaojz@163.com, byhdeng@scut.edu.cn,c53423729@qq.com Keywords: Alkali lignin; Aggregation; Self-assembly Abstract: Alkali lignin (AL) was used as a polyanion to form layer-by-layer self-assembled film with PDAC as a polycation.
Its structure in wood was visualized as being branched with linear chains crosslinked by a variety of interchain covalent bonds[2].
However, lignin has a very complex the structure and easily form the assemble structure.

The thin film was annealed at 300°C to modify from amorphous to the anatase structure.
The anatase nanoparticles were also observed to have structures of bipyramidal and pseudocubic.
This was due to the better charge transfer between the pandan dye molecule and the TiO2 surface which was related to the dye structure.
