The research then focused on materials in which some atoms only weakly bound to the others in the crystal structure.
This might be due to the sluggish kinetic factor of the components for such a complex crystal structure during reactions.
The increase of S with increasing temperature, even sign-changing, corresponds sensitively to the band structure of materials.
This indicates that the substitution can change significantly the electronic band structure, which is also reflected by the temperature dependent Seebeck coefficient.

The higher temperature of heat treatment caused the change of crystalline structure and the increase of the crystallinity of ZrOxNy.
While, the crystal structure of ZrOxNy changed at around 500 oC.
Therefore, the change of temperature dependence of ORR current density was probably caused by the change of crystal structure.
This means that the crystal structure might have a large effect on the electrocatalytic activity for ORR.

This decrease is accompanied by a lessening of intensity of the high-momentum emission of the annihilation radiation thus bringing in a direct evidence of a multi-vacancy structure of the vacancy-group-V-impurity atom complexes after n-pconversion; the electron density was found to be affected by the localized deep acceptor states related to these centers.
The electron structure of the ion core of As5+ closely resembles that of Ge4+ ion core whose subvalent shells are capable of interpenetrating thus affecting the overlapping of the positron and core electrons wave functions.5 Similarity of electron structure of As5+ and Ge4+ ion cores makes for increasing of the electron density around the positron due to relaxation effects.6 Electron Density Beyond Ion Cores in DV Complexes (Materials Before n-p-Conversion).

The selected CNC equipment adopts an open structure and an oblique base.
In the consideration of the ease of mobility and the human nature of operation, the external structure of traditional CNC machine is improved from the following aspects: both the left and the right side are changed into open structure to facilitate the transmission of products on the equipment; the base adopts the oblique type, getting an angle of 53 degree from the horizontal plane; rollers are installed on the table along the two directions, so the automatic positioning and transmission of products can be realized

Preparation and Properties of Chitosan-Tranexamic Acid Salts Zhang Hua*, Yaqi Qinb, Sitong Luc, Churu Huangd and Zekun Chene School of Chemistry and Environmental Science, Guangdong Ocean University, Zhanjiang 524088, Guangdong, China ahuzhangqyx@126.com, b2516927675@qq.com, csmelilst@163.com, d983621355@qq.com, e2452723438@qq.com Keywords: chitosan, tranexamic acid, salts, hemostasis Abstract.
The physical properties including water solubility and stability of the prepared samples were tested, and their structures were characterized by Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD).
The physical properties and chemical structure of chitosan-tranexamic acid salts were determined, and the preliminary hemostatic activity was evaluated in vitro as well.
The chemical structure analysis of chitosan-tranexamic acid salts was conducted by FTIR as shown in Figure 1.

The Electrosynthesis and Characterization of Thienyl-group-bearing Acrylic Polymer as Precursor for Electrochemical Reaction of Thiophene Side-chain Lu Hana, Yongluo Qiao, Weiqiang Zhou, Liang Shenb*, Jingkun Xuc* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University, Nanchang 330013, P.
The structure, electrochemical, optical, thermal properties and morphology of as-formed electropolymer were systematically investigated by FT-IR, cyclic voltammetry, UV-vis, thermogravimetry and scanning electron microscopy.
With the continuous development of conducting polymers during the latest decades, the interest in settling the problem about poor processability, including poor film-forming ability, poor solubility and thermal tractability, induced by the stiff polyconjugation structure drives intensely several workers to combine the thiophene ring with a conventional insulating polymer, which can increase the solubility of the resulting block or graft copolymers[8].
In general, the lower potential is beneficial to get high-quality film while, under the high potential, it can easily result in peroxidation accompanied with side reactions, which produces conducting polymers with poor properties, even to destroy the their structures[15].

X-Ray diffraction spectra showed that the crystal structure of NiZnFe2O4/SiO2 has a mixed cubic spinel structure.
Results and Discussion Crystal Structure Figure 3.
XRD shows that the crystal structure of NiZnFe2O4/SiO2 is a mixed cubic spinel structure, due to NiFe2O4 with inverse spinel structure and ZnFe2O4 a normal spinel structure.
NiZnFe2O4/SiO2 has a mixed cubic crystal structure, with the highest particle size of 9.6 nm.

Alternative methods to fabricate dense HA-ZrO2 composites should be introduced by changing the structure of HA, intrinsically.

Calculation of PEC from measured concentrations and the comparison of this value to the usespecific quality criteria is a good solution for surface waters or subsurface water-bases, but the solid phase containing environmental elements, the soil and sediment, are more complicate structures, than the water.
