It is found that the formation of perovskite structure is directly related to the content of Mn and calcining temperature.
According to Goldschmidt's law of crystal chemistry, the left-hand side of (2) is called tolerance factor.
The calculated result indicates that SFMN is supposed to have a very stable double-perovskite structure.
The double-perovskite structure of SFMN is stable under both oxidizing and reducing atmosphere.

In this way, it belongs to the area of chemistry.
The wood extractives appear normally as a numerous mixture of compounds with similar or almost similar chemical structure, and therefore the analysis and the separation of individual compounds needs precautions and high carefulness in the methods used as well as in the purity of conditions during operations.
Extraction results indicate thermal degradation even in lignin, the strongest constituent of the cell structure, in ash more than in beech.
This paper belongs mostly to the area of chemistry, but partially also to the area of industrial applications.
The degradation appears to be mainly due to the opening of interfaces of the cell structure.

The structure of the defect complexes is determined.
In all cases their structure can be characterized as distorted rectangular pyramid (Fig.3).

Gold nanoparticles have excellent properties for tailoring size and shape to architect nanoscale structure, enhancing sensing and detection capacity by several magnitudes.
They are imperative nanomaterials with cylindrical structure with optical and mechanical properties for DNA detection and divided into single-walled nanotubes (SWNTs) and multiwalled nanotubes (MWNTs).
Conclusion Nano-structured materials have opened up a wide ranging choice for the ultrasensitive detection of DNA.

Scaling Mechanism of Heat Exchanger for Spent Sulfuric Acid Concentrating in Titania Production Lifen Yang 1, a, Bin Xiang2, b,Lianghui Ke3,c 1 College of Chemistry & Chemical Engineering, Chongqing University , China 2 College of Chemistry & Chemical Engineering, Chongqing University , China 3 Chongqing Titanium industry Co.LTD of Pangang Group,Chongqing, China aoylf.8898@163.com,bxiangbin@cqu.edu.cn,c kelhui@163.com Keywords:spent acid concentration; scaling mechanism; deposition Abstract.The component and contents of scale sample on the graphite heat exchanger were analyzed by ED-XRF( Energy dispersive X-ray fluorescence spectrometer) and the component and contents of spent acid unconcentrated and concentrated were measured by AAS(atomic absorption spectrometer).In addition, the phase structure of scale sample was tested by XRD(X-ray diffraction) and the simulation experiment of spent acid concentrating was carried out to study the scaling mechanism in the laboratory.
Experiments Component and structure of scale analysis.
A piece of powder scale sample obtained from graphite tube was tested by ED-XRF(Jordan Valley EX-Calibur) and XRD(shimadzu XRD6000X）, respectively, to determine its component and structure.

The overall porosity of the 3D structures is contributed by the presence of both pores-by-process (PBP) and pores-by-design (PBD).
This disables the measurement of the actual porosity as the mercury cannot penetrate into the entire structure.
