Crystal Structure The crystal structure of NNSH was solved by X-ray single crystal diffraction method.
From crystal chemistry viewpoint, a high ionic radii of metal cations {R(M+)} and {R(M´2+)}, low numbers of crystal water molecules are favorable for crystallization of M2SO4·M´SO4·nH2O double salts.
NNSH crystal is four water structure while the others are six water structure.

Influence of ultrasonic energy on pore structure of Ni-P ultra-black films produced by a novel blackening process Yongzhong Jin1, 2, a, *, Kui Yang1, b, Xianguang Zen1, 2, c, Panpan Yue1, Guoqing Zeng 1 1 Department of Materials and Chemistry Engineering, Sichuan University of Science and Engineering, Zigong 643000, P.
Blackened treatment of Ni-P deposits is industrially carried out by chemistry etching, for example in nitric acid solution, which can not meet the demands of ultra-black materials with the expected porosity and structure.
Here, ultrasonic oscillation was purposely introduced into the blacking system in order to optimize the structure and distribution of etching pores.
An etched film with surface porous structure was formed.
However, it is surprising that there is a completely different pore structure on the etching surface in Fig.1c and 1d, in contrast with Fig.1e and 1f.

Their structure and properties were characterized by scanning electron microscopy, Raman microscopy and mechanical testing.
SEM photos were used to investigate the structure of GO/PAM (figure 1b, c).

Synthesis of LaMnO3 via a Mechanochemical Activated Process Hao Wu 1, Qiming Xu 1, Qiang Li2, Cheng Zhang3 and Danyu Jiang1 1 Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai, China 2 Department of Chemistry, East China Normal University, Shanghai, China 3 Department of Materials Engineering, Shanghai Institute of Technology, Shanghai, China Keywords: LaMnO3, mechanochemical Abstract.
LaMnO3-based perovskite oxides are typical functional materials applicable to various devices for its chemistry and physics properties.
It is well known that the structure and properties of the materials depend on their synthesis process.
Since the solid-state reaction method has some drawbacks of high reaction temperature, large particle size and limited degree of chemical homogeneity, many soft chemistry methods have been developed to synthesize LaMnO3 perovskide materials, such as sol-gel, polymeric gel, amorphous citrate and coprecipitation [7-9].

Clay mortars have been used for a long time in the construction and restoration of historical and cultural structures.Currently, Italian dry lime mortars (MAPE ANTIQUE) are imported to the Republic of Armenia for use in the rehabilitation of structures.

However, the structure is still limited to the keggin structure, and there are few reports of HPCs with other structures (such as the Dawson structure) [12-13].
Moreover, the oxidation method meets the needs of contemporary green chemistry and is a new Mo-based heteropoly compounds reaction system methods for efficient synthesis of AA.
