Abstract
Calcium silicate was successfully synthesized using agricultural byproduct such as rice husk ash and shell of snail namely Pomacea canaliculata by solid state reaction.
The structure of the XRD pattern of calcium silicate was not changed with increasing the milling time.

And we can conclude that the structures of the new dye-polyether derivatives were confirmed.
From the point view of adsorption and molecule structure, YL207 and YL300 perform better than the two other dye-polyether derivatives.

Introduction
Acrylic gel fiber (AGF) is a kind of copolymer with network structure [1] inside.
Then Flory ion network structure theory is not applicable therefore and the absorption capacity of water and Cu2+ decreases to the minimum.

Now PM technology develops to multi-alloying and full density sintering, especially, for powder sintering structural steels, good structure and high density are foundation of which obtain high performance[4].
Because density and strength of hot-forging micro-structure is high, during dry sliding friction, the plastic deformation was unappeared or just small in the subsurface under lower load.

Introduction High dielectric constant materials with perovskite structure of A(Fe0.5B0.5)O3 where A= Sr, Ca, Pb; B= Nb, Ta, and Sb have been extensively investigated by reason of their potential for dielectric applications [1-4] Sr(Fe0.5Nb0.5)O3 (SFN) is another high dielectric material with orthorhombic crystal symmetry and with space group Pbnm(62) [5].
Further, there was no measurable change in the d-spacing for different sintering temperatures, indicating that the sintering temperature range in the present work (1400-1500 oC) had the same effect on the crystal structure of the sintered ceramics.

Consequently, heparin-like protein separation materials with negatively charged, such as cellulose derivatives, are worthy substitutes of heparin, which not only overcome disadvantages such as instability of heparin activity and easy to carry zoonotic pathogens, but also keep a uniform structure and the low price.
Effect of sulfonation time on static angle The chemical composition of the surface layer of nanofiber membranes samples was analyzed with ATR-FTIR spectroscopy (Fig 2), which has been widely used to follow chemistry changes on polymer surfaces.
It was found that platelet adherence on the membranes was strongly dependent on the chemical structure of the membrane surface.
