Introduction In recent years, with the increase in demands for global environmental conservation, green or environment-friendly materials are being actively developed.
However, as the materials with low surface tension such as resin materials have a good wetting and spreading characteristics on the surface of both metal and resin, it has been known that it is impossible to obtain the self-alignment capability with them.
Material properties of resin materials diluted with BCA (Butyl Carbitol Acetate) were shown in Table 1.
Generally, the liquid resin materials have considerably high viscosity (several Pa⋅s ~ several hundred Pa⋅s) comparing that of molten solder (about ��× 10-3 Pa⋅s).

Synthesis and Crystal analysis of nano Metal-organic frameworks MIL-53(Cr)1 TAN Hai-yan, LIU Cheng (Faculty of Material Science and Chemical Engineering , China University of Geosciences(wu han); Sustainable Energy Laboratory , China University of Geosciences (Wuhan).
Introduction Metal organic framework materials (metal-organic frameworks, MOFs) are a new kind of nano-porous materials over the past decade by the widespread concern in the academic community.
It is the framework material of the organic ligand with a metal ion having a periodic network structure formed by the self-assembly process[1].Because of their processability, flexibility, structural diversity and geometrial control, MOFs have broader application prospects than other porous materials,Such as adsorption separation, catalysts[2-4], magnetic materials and optical materials, battery materials[5,6].
In the above-described materials, terephthalic acid(H2BDC) is one of the earlier, commonly used carboxylic acid organic ligand.Serrc[7] with H2BDC ligands by hydrothermal synthesis method has synthesized the metal organic framework compound MIL-53(Cr).

Materials and methods Sediment traps The study site and the sampling stations are as shown in Fig. 1.
Sediment samples All sediment from the trap was transferred to sealable plastic bags very carefully to avoid any external material adding into the sample or to avoid any portion of the sample being excluded.
