Introduction The heteropoly compounds with Keggin structure have been widely used in organic synthesis [1], pharmaceutical chemistry [2] and other fields for their unique structure and the excellent catalytic performance, and were used to treat wastewater as the catalyst by many experts [3].
The character peak of the heteropoly salts with Keggin structure appears fingerprint region at the range of the 700-1100cm-1[4].
Combined with FT-IR and UV spectra, it was sure that Na6[Mn(ZrMo11)O39]•19H2O possessed Keggin structure.
The results showed it possessed Keggin structure, regular crystal and had a good thermal stability.

Subtle variations in chemistry or processing methodology have been exercised to achieve the desired microstructure and properties.
The chemistry modification changed the structure to dual phase, austenite – ferrite structure, that responded to heat treatment by transformation of austenite to martensite.
This dual phase structure after tempering enhanced the strength and toughness by 25% and 60% respectively.
The new steel has dual phase (austenite and martensite) structure in hardened condition.
On cooling to room temperature a complete martensitic structure is obtained.

This paper reviews the process property observations between the growth conditions, the epitaxial wafer metrics and the variables critical for fabrication of optimal epitaxial structures.
As a means of assessing the epitaxial material's suitability for device fabrication simple Schottky structures have been fabricated by sputtering nickel contacts through shadow masks.
Figure 1 compares this data with other growths performed using silane and silane/HCl chemistries.
It is observed that ancillary downstream deposits are minimized with chlorosilane chemistries.
These results show that chlorosilane-based chemistries common to commercial silicon epitaxy are compatible with processes to deposit high quality SiC epitaxial layers suitable for device fabrication.

Abstract: The filling of carbon nanotubes with Fe-Mn oxide via wet chemistry was presented.
Excellent properties of carbon nanotubes including novel hollow-tube structure, nanometer, dimensions, high spscific surface area, conductivity, low resistivity, chemical stability make cnts nanoparticles promising for applications in supercapacitor[2].
Experimental Sections The multi-walled carbon nanotubes (MWCNTS), prepared by the natural gas catalytic decomposition over Ni-based catalyst, were gifts from Chengdu institute of Organic Chemistry (P R China),which had an inner diameter in the range 5~15 nm and an outer diameter in the range of 30~50 nm.
Except the peaks corresponding to the structure of purified MWCNTS( Fig.2a), some new peaks with comparatively visible diffraction broadening occurred in (Fig.2b), the peaks could be indexed as Fe2O3 and MnO2 (Joint Committee on Powder Diffraction Standards(JCPDS) card no.12-0720,13-0534).
