The SEM-EDS image showed that activated carbon have many porous structure and the strong peak of C was 92.7 %.
The surface chemistry of the activated carbon after chemical activation underwent some changes.
It can be seen that activated carbon have many porous structure.
The commercial of activated carbon normally has a very porous structure with a large surface area ranging 300-3500 m2/g [20].

Usually, metal phosphate with layered structure can be obtained by hydro-thermal or solvent-thermal method or solid-state reaction.
Conclusions Solid-state reaction at low temperature can be used to prepare NaZnPO4·H2O with plate or layered structure.

Synthesis and Crystal Structure of a new Ni2+ Complex1 Yinzhi JIANG1, a, Yang ZOU1, b and Lianqun ZHANG1, c 1Department of Chemistry, Zhejiang Sci-Tech University, Hangzhou 310018, China ajiangyinzhi2003@yahoo.com.cn (corresponding author), bnjuzyang@163.com, czhejianglujun@sohu.com Keywords: Schiff base; Synthesis; Decomposition; Mechanism; Crystal structure Abstract.
We reported herein the synthesis, characterization and crystal structure of the complex 2 (Scheme 1).
The structure was solved by direct methods (SHELX-97) and expanded with successive Fourier technique.
The molecular structure of the complex 2 with atom numbering scheme is shown in Fig.1.

To simulate pattern deformation during the drying process of wet cleaning, we created a FinFET model as a HAR structure.
In this study, we performed simulations of pattern collapse in water-placed FinFET structures to simulate the pattern deflection.

Synthesis and Spectroscopic Properties of Novel Chiral Amino Acid Tailed Porphyrins Jun Xuea, Yajun Wanga, Mingyi Raoa, Guotian Luoa,b* aCollege of Chemistry and Chemical Engineering, Gannan Normal University, Ganzhou, 341000 bKey Laboratory of Organ-pharmaceutical Chemistry , Jiangxi Province,Ganzhou, 341000 a,bemail: luogt@yahoo.com.cn Keywords: synthesis, amino acid ,porphyrin, spectral property.
Introduction Molecular recognition of amino acids and their derivatives has been one of most attractive objectives of host-guest chemistry 1,2.
The yield of amino acid tailed porphyrins was 16~50%.1H-NMR spectra are in complete accord with the proposed structures 2-7.
To confirm the molecular structures the IR spectra of the synthesized porphyrins were investigated.
Together with the NMR data they reliably prove proposed structures 2~7 in all cases.

These analyses deduce that some few complex idea fields, including structural stress, physics and chemistry field, with spatial and temporal evolution exist in the narrow friction zones, moreover, they viably regulate the nanoparticle distribution. 1.
(a) Densely individual nanoparticles arrange into nanoline (arrow showing) with intuitive direction and layering structure.
In microscopic structure field, Xypolias[21]suggested that there are three shear kinds, i.e. simple ,pure and general shear.
Thus we may look upon the deformed structure as the simple shear pattern rather than the rotational one. 4.

The surface and structure of PS layers were examined in terms of electrochemical/surface parameters.
The surface and structure of PS layers were studied by SEM and in-situ EIS techniques.
In all cases, similar sponge-like structure of PS layers was observed for both n(100) and n(111) with more interconnected and finer textures as seen in Fig. 2(b).
