(5) The dissolution mechanism involves the structure and bonding mechanism of cyanide and oxygen adsorbed on palladium atom.

Since the difference of molecular structures between sodium oleate and sodium stearate, the entirely different distributions of products were obtained.

Utilization of XPS analysis for the characterization of mechanochemical activation in polymer-cement composite materials Lukáš Kalina1,a, David Matoušek1,b and František Šoukal1,c 1 Brno University of Technology, Faculty of Chemistry, Materials Research Centre Purkyňova 118, 612 00 Brno, Czech Republic akalina@fch.vutbr.cz, bxcmatousekd@fch.vutbr.cz, csoukal@fch.vutbr.cz Keywords: X-ray photoelectron spectroscopy (XPS), mechanochemical activation, polymer-cement composite Abstract.
However, the studies on the chemistry and the microstructure of the calcium aluminate MDF materials recognized the chemical reactions occurring between the polymer (the polyvinyl alcohol/acetate) and the inorganic ions produced when the cement dissolved in water [4].
The spectrum of calcium Ca 2p shows two different chemical states which is consistent with the structure of this phase [8].
Fig. 2 C 1s and Al 2p curve fitted XPS spectra of mechanochemicaly activated phases Conclusion The XPS analysis provides very successful method for the study of the composition and interphase structure of surface layers at the molecular level.

Low-temperature self-mixing combustion synthesis of spinel LiMn2O4: effect of igniting temperatures Guiyang Liu1, a, Junming Guo2, Baosen Wang1, Ying He1, Zhang LiLi1 1College of Science, Honghe University, Mengzi Yunnan, China 661100 2Key Laboratory of Ethnic Medicine Resource Chemistry，State Ethnic Affairs Commission & Ministry of Education，Yunnan University of Nationalities, Kunming Yunnan, China 650031 aliuguiyang@tsinghua.org.cn Keywords: Low-temperature self-mixing combustion synthesis, lithium ion batteries, spinel Abstract.
The possible reasons are generally believed to originate from the Jahn-Teller distortion of the cubic spinel structure of LiMn2O4 during discharging with increasing Mn3+ in the structure, the gradually dissolution of Mn3+ to electrolyte via disproportionation reaction and the decomposition of organic solvent at higher potentials [3].

Moreover, SAED image reveals unsatisfied crystalline structure.
Conclusions In this work, different structures of CoO and Co3O4 nanoparticles have been prepared by a simple salt-assisted combustion method.

Obviously, the concentration factor has a significant influence on the chemical composition, structure and properties of the products of synthesis.

Every year, many new technologies were reported in green and sustainable chemistry, which were regarded as a major scientific discipline [7-8].
Fig. 4a showed a diffuse diffraction pattern, without the sharp diffraction peak of crystalline SiO2, only at a 2θ (22°) there was a wide diffraction peaks, which indicated that the sample was mainly amorphous structure.
Comparing the XRD pattern of silica power and crystal silica showed that the sample was amorphous silica powder structure.
