The peaks of ZF ferrite presented at 18.37°, 30.34°, 35.52°, 43.17°, 53.70°, 57.14°, and 62.76° in Fig. 1(g) are indexed as a spinel structure with the reflections of the Fd3m cubic group (JCPDS no. 22-1086).
It can be seen from Fig. 2(c, f) that the typical layer structure of EG is kept well in ZF/EG composites, and the spherical ZF particles grow in the interlayer of EG to form intercalation compounds, and their average size is smaller than that of pure ZF particles due to restriction of the interspace.

Synthesis and properties of 1,4-bis(2'-aryl-1',3',4'-oxadiazole)-1,3-butadiene and its analogues Yiping Qian*, Xionglu Zhang*, Yuanyan Li, Xiaolin Fan Key Laboratory of Organo-pharmaceutic Chemistry of Jiangxi Province, Gannan Normal University, 341000, Ganzhou, China E-mail: qyp511@yahoo.com.cn, x.i.o.g@126.com Keywords: Oxadiazoles, fluorescence, electronic transmissions Abstract. 1,3,4-oxadiazole (OXD) and its derivatives have excellent thermal stability and oxidation resistance and strong blue fluorescence emission.
Six novel compounds have been designed and synthesized, and their structures were confirmed by 1HNMR, FT-IR and MS.
A series of oxadiazole ring containing 1,3-butadiene compounds were synthesized, using 1H NMR, FT-IR, MS to verify their structures, and studied their UV-visible absorption spectroscopy, fluorescence spectroscopy and electrochemical properties.
The results indicated that 5a-5f could launch a strong blue fluorescence. we have seen that the largest emission wavelength of a benzene ring has electron-donating (or electron-withdrawing) substituent are bathochromic shift, this phenomenon is mainly due to these compounds are a class of plane symmetric rigid molecular structure, so its molecular polarity is very small.
The data can make the electrode materials and luminescent materials and carrier transport materials between the sub-band matching, which can provides an idea theoretical basis for optimizing the device structure and improving device efficiency.

The influence of biologically active Mg and Sr addition on HAp crystalline structure and thermal behavior was assessed.
Thus, the main goal of this work was to evaluate the effect of Sr and Mg (up to 3.50 wt%) on crystalline structure and thermal behavior of nanocrystalline HAp synthesized through modified wet precipitation method close to 0 oC.
Molecular structure of the as-synthesized and calcined products was studied using Fourier transformation infrared spectroscopy (FT-IR, Varian 800) in the attenuated total reflectance (ATR) mode.
Consequently, the ability of the elements to substitute for Ca in the HAp structure depends on the difference in atomic size, i.e., the greater the difference the more difficult is substitution.
All of the data represent the evidence that chemical modification with 3.6 ± 0.4 wt% of Sr or 2.8 ± 0.3 wt% of Mg played a critical role in tailoring crystalline structure of the products.

The article analyses the application of a composite material based on magnesite cement and red mud for the production of high-resistant materials and structures.
The advantage of this direction is that the composite material created on the basis of “red mud” has increased strength and water resistance; also, it has the structure of a homogeneous monolithic stone.
The main difficulties here are related to the features of red mud as a poor raw material compared to conventional ores, significant fluctuations in the chemical analysis, as well as its fine heterogeneous structure.
Red mud is a plate material [1] Red mud is a highly toxic waste product containing more than 6.0 kg of alkali in 1 ton of pulp of red mud [2] Red mud can be used as an inexpensive and common option compared to other components, for example, bentonite (Al2[Si4O10](ОH)2·nH2О), for hardening of iron ore agglomerates and pellets The liquid-solid ratio in red mud is normally 3:1, directly in the production process [7] Red mud is able to prevent polymorphy of bicalcium silicate located in the structure of agglomerates, which reduces the internal stresses that destroy them.[1] Red mud is a multicomponent substance harmful to the environment due to improper recycling and deliberate release into rivers and lakes [8] Redmud has a sweetening ability in contact with poultry and livestock organic waste and effluents [1] Red mud is an environmental threat to the territories adjacent to the mud storage facilities.[2] Red mud is characterized by high sorption capacity when nitrogen and sulfur compounds
