The drawback of conventionally produced Fe 21Cr 5,5Al materials is the relatively low mechanical strength that the ferritic structure offers at high temperature.
The transport properties and over all oxide growth rate is however a result of many parameters including details in the chemistry of the alloy and the surface chemistry of the oxide [5,6,7].
A fine-grained recrystallised structure is maintained for long times at high temperatures without significant grain growth.

In Situ Rapid Dechlorination by Microwave-Assisted Catalytic Reduction of Chlorobenzene and 1,4-Dichlorobenzene on Raney Ni-Al Alloy Catalyst Baoying Lu1,a, and Xuhe Hou1,a* 1Guangxi University of Science and Technology, Chemistry Department, 545000, Liuzhou, China a*Corresponding author: 100000778@gxust.edu.cn Keywords: Microwave-assisted catalytic reductive, Dechlorination, Raney Ni-Al alloy catalyst Abstract.
Moreover, Raney Ni skeleton structure can be obtained, which improves the efficiency of catalysis for rapid dechlorination reaction.
The dechlorination experiments were carried out on the microwave digestion system (MDS-6, 400W, Sineo Microwave Chemistry Technology Co., LTD, China).
The surface area of Raney Ni-Al alloy could not be measured because it was not in porous structure.

Introduction Since the carbon nanotube (CNTs) was discovered, nano/micro-structured carbon materials have obtained more and more attention because their unique physical and chemical properties provide various potential applications.
Morphology observation and structure characterization.
The nanocomposite prepared suspension was casted on the interdigital electrodes of Au on flexible PET substrate, after drying, the photoconductivity response to visible light (20-25 W) and 808 nm laser with low-power were determined with LK2000A Electrochemical Work Station from LANLIKE Chemistry and Electron High Technology Co., Ltd (China).

Research showed that in the chemical structure of the saponins, CH2OH at the C-4 position of bayogenin and the carboxyl group at C-17 of the agylcone seem crucial for acute anti-inflammatory effect[5].
The basic idea is that different indicators are sorted by the importance and an orderly hierarchical structure was established.

The Alkaline Activation of Calcium Oxide on Phosphorous Slag Powder Cementing Material in Autoclaved Curing Jianxin Caoa, Lin Yangb, Qian Linc, Guangshan Baid and Fei Liue School of Chemistry and Chemical Engineering, Guizhou University, Guiyang, Guizhou, 550003, China ajxcao@gzu.edu.cn, bce.lyang@gzu.edu.cn, ccelinqian@126.com, dbaiguangshan001@ 163.com, ece.feiliu@gzu.edu.cn Key words: Autoclaved Curing, Calcium Oxide, Phosphorous Slag Powder Cementing Material, Hydration Products.
The chemical contents of the phosphorous slag powder were analyzed by the method of GB/T 176-2008 (Analytic technique for cement chemistry).
The structure which is formed from unhydrated phosphorous slag powder due to the weak existence on the interface binding domain results in the decrease of the strength of hydration products.
The hydrone would be destroyed and dissociated to produce very strong H+ and OH-[7] when the temperature reaches over 100˚C so that the hydrone in steam could enter into the structure of new material in different forms.

Characterization of Low- and High-Calcium Pond Ashes and their Applicability for the Preparation of Alkali-Activated Pastes Jadambaa Temuujin1,a, Uyat Bayarzul2,b 1CITI University, Denver Street 34, Ulaanbaatar 14190, Mongolia 2Institute of Chemistry and Chemical Technology, Mongolian Academy of Sciences, Ulaanbaatar, Mongolia a,*temuujin.jadamba@citi.edu.mn, bbayarzulu@mas.ac.mn Keywords: Coal types, Pond ashes, Chemical and Mineralogical composition, Microstructure, Alkali-activated paste, Mechanical properties Abstract.
Adsorption-desorption isotherms of both pond ashes reveal the almost non-porous structure of the Erdenet pond ash.
Although SEM and Surface area data show the non-porous structure of the Erdenet pond ash, the high magnification micrograph reveals surface dissolution occurs also in Erdenet pond ash.
Therefore, we suggest that the sluggish reaction of the solution chemistry in pond ash is the main reason for the low mechanical properties of the pond ash-based alkali-activated materials.

The main difficulty of the process is the need for preliminary synthesis of a N,P,B-containing organosilicon component with a developed structure.
In this case, using appropriate catalysts for hydrolysis, it is possible to initiate a given polycondensation mechanism and obtain a pre-planned gel structure. 2.
It is shown that the elasticity of the fibers and the surface coverage depends on its surface chemistry and is maximal when the minimum number of base centers of Lewis (Lb), the acid centers of Bronsted (Ba), and the base centers of Bronsted (Bb) are on the coating surface.

It has received significant attention as a main constituent components of blend film [10] and widely used in medicines, dentistry, food processing chemistry, biotechnology, agriculture and environmental protection [11].
This interaction may have caused embrittlement of network structure and hence decreasing film tensile strength [23].
It is conformational a high crystallinity indexes causes the change of film structure.
