Synthesis, crystal structure, and properties of a new zinc coordination polymer [Zn(PMP)₂Cl] _n

Journal of Coordination Chemistry (2009)

Rui‐Bo Xu Xing‐You Xu Yuhe Yin Mingyan Wang Xujie Yang

A new coordination polymer [Zn(PMP)2Cl] n (PMP = 1-phenyl-3-methyl-5-pyrazolone) has been prepared by the reaction of zinc chloride and PMP, and characterized by elemental analysis, IR, UV, and fluorescence spectra, TG/DTA, and electrochemical analysis. Single crystal X-ray diffraction revealed that the complex is monoclinic, space group P 2(1)/n, with a = 10.850(17), b = 17.578(2), c = 10.997(18) Å, β = 104.999(3)°, V = 2025.8(5) Å3, Z = 4, Dc = 1.470 mg m−3, F(000) = 920, goodness-of-fit = 0.905, and R 1 = 0.0441. The complex is a 1-D coordination polymer, and the coordination geometry of Zn(II) is a distorted tetrahedron.

Finite element analysis of pulsed wire deformation in the small gap of permanent magnetic device

Dianji yu kongzhi xuebao (2011)

Mingyan Wang

It is always a problem of the magnetic field measurement in small via hole of a long magnet device,because the size,sometimes less than 0.5mm,is too limited for the magnetic probe.The infromation of magnetic field can be obtained from the deformation of a current wire in it.In this paper,instead of analytical deduction,a wire analysis method based on finite element analysis(FEA) was proposed to build the relationship between the wire deformation and the magnet parameter,e.g.the magnet size and the distribution etc.The coupled analysis theory of electric,magnetic and stress field using FEA is discussed,the basic models of different shape magnet are built,and the simulation results were presented.It shows that the relationship between magnet parameters and wire deformation could be built by this platform,and this method could be used for the improvement of magnet design and magnetic field distribution.

Statistical behaviour of interfaces subjected to curvature flow and torque effects applied to microstructural evolutions

arXiv (Cornell University) (2021)

Sebastian Florez Karen Alvarado Brayan Murgas Nathalie Bozzolo D. Chatain

The movement of grain boundaries in pure metals and alloys with a low concentration of dislocations has been historically proved to follow curvature flow behavior. This mechanism is typically known as grain growth (GG). However, recent 3D in-situ experimental results tend to question this global picture concerning the influence of the curvature on the kinetics of interface migration. This article explains, thanks to 2D anisotropic full-field simulations, how the torque effects can complexify these discussions. It is then illustrated that neglecting torque effects in full-field formulations remains potentially a strong hypothesis. The apparent mobility can be much more complex than expected without necessarily questioning the influence of the curvature on the local kinetic equation.

Hydrodynamic characteristics of vertical V type otter board

JOURNAL OF FISHERIES OF CHINA (2004)

Mingyan Wang

This study inspected the effects of main structure parameters of otter board on the hydrodynamic characteristics of vertical V type otter board by the orthogonal design and appending the simulated sea bottom, based on the test of model in the wind tunnel. The test results indicated as follows: 1. one of the most important factors to influence the hydrodynamic characteristics of otter board was dihedral angle, followed by aspect ratio and sweepback angle. When the curvature on surface of otter board is 14%, the dihedral angle of the optimal match was 12°, aspect ratio was 1.60 and sweepback angle was 10°. The lift coefficient was 1.68 and higher than tested other boards when attack angle was 25° and 28°. 2. the critical angle of attack of the optimized otter board is reduced from 28° to 25° after appending the simulated sea bottom. It was obvious that the attack angle of vertical V type otter board on bottom was less than that in middle water. 3. the lift coefficient of the optimized otter board was obviously raised in the range of the commonly used attack angle after appending the simulated sea bottom. Meanwhile the lift to drag ratio also rose slightly. However, the lift to drag ratio held the line at attack angle of 20°. 4. in the front of the critical attack angle the moment coefficient of the optimized otter board rose slightly after appending the simulated sea bottom and it was favorable for the stabilization of otter board in practical operation.

Facile Construction of Cu/ZnO Heterojunctions for Enhanced Photocatalytic Performance

NANO (2022)

Hong Peng Zhao Zhenghua Du Diandian Liu Yijian Lai Tao Yang

The design and construction of semiconductor–metal heterojunctions are being considered to be an effective way to overcome the limited visible-light absorption of semiconductors. Herein, a facile and scale approach is reported for the first time to synthesize Cu/ZnO heterojunctions by one-step galvanic replacement between Zn and cuprous solution reaction. Two kinds of morphologies Cu/ZnO heterojunctions could be obtained by changing cuprous salt anion such as Br − , Cl − and I − . A flower-like Cu/ZnO heterostructured is chosen as a representative to demonstrate the facility and enhanced photocatalytic performance toward Rhodamine B degradation under visible-light irradiation. Results showed flower-like Cu/ZnO heterojunctions have higher photocatalytic performance than the other two morphologies. The galvanic replacement growth mechanism of Cu/ZnO heterojunctions was also further investigated. It is found that Cu/ZnO heterojunctions formed from Zn and Cu 2 O at an acid solution and room condition. This work indicates that galvanic replacement reaction at room temperature is an excellent technique to grow Cu/ZnO heterojunctions and demonstrates that the hole and electron transfer between Cu and ZnO can efficiently enhance their photocatalytic performance. This general method can also be further explored to guide the design of metal/metal oxide heterostructured on other substrates, such as Zn, Ni and Cu foils.

Fabrication and characterisation of MnOOH and β-MnO₂nanorods with rectangular cross-sections

Journal of Experimental Nanoscience (2012)

Dongen Zhang Qing Xie AiMei Chen Mingyan Wang Xiaobo Zhang

MnOOH nanorods with rectangular cross-sections have been successfully prepared in high yield via a hydrothermal reduction process at a low temperature. After the subsequent heat treatment of the as-prepared MnOOH nanorods at 350°C for 6 h in air, β-MnO2 nanorods with rectangular cross-section that retained the similar morphologies of MnOOH nanorods were obtained. The products were characterised by powder X-ray diffraction and field-emission scanning electron microscopy. The influences of different degrees of pH on the morphology and phase of the final products under hydrothermal conditions are discussed.

Reducing the Flocculation of Milk Tea Using Different Stabilizers to Regulate Tea Proteins

Foods (2023)

Yuqi Song Xiaosen Wang Haixi Luo Mingyan Wang Jian Chen

The regulation of flocs derived from polyphenol-protein formation in milk tea has not been fully explored. In this study, the flocculation of milk tea was regulated by adding 10 kinds of stabilizers with different characteristics. The stability coefficient and centrifugal precipitation rate were used as indexes. The optimal concentration ratio of the complex stabilizer was identified using the response surface methodology (RSM), being 0.04% for Arabic gum, 0.02% for β-cyclodextrin and 0.03% for Agar. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to analyze the characteristics of different stabilizers in milk tea, and our findings were as follows: (1) The relative strength of the peaks in different stable systems was different. The absorption peaks were mainly near the wave numbers 3376 cm-1, 2928 cm-1, 1655 cm-1, 1542 cm-1, 1408 cm-1, 1047 cm-1 and 925 cm-1. (2) The milk tea system was an amorphous structure. The diffraction peak of the composite system was observed to be about 20°. The crystallinity of the milk tea in the compound group was 33.16%, which was higher than that of the blank group (9.67%). (3) The compound stabilizer reduced flocculation, and the stabilizing agents improved the surface order of milk tea. These results indicate that the combination of polysaccharide stabilizers (Arabic gum and agar) and oligosaccharide stabilizers (β-CD) in certain proportions can regulate the flocculation of milk tea and improve its stability. The potential research avenues involving polyphenol-protein complex instability systems and their applications in food development are expanded by this work.
