Chijia Wang,Qianqian Yin,Shuyi Liu,Jianxin Wang,Weihao Fan,Zhanjian Liu,Fatang Liu,Yize Liu,Huaiyuan Wang 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.128 No.-
Coating technology is the most economical and efficient approach to retard metal corrosion, and newcomposite coatings prepared by adding monoatomic fillers to a polymer matrix have excellent corrosionresistance and good mechanical properties. The single-atom coating formed by the immobilization ofmetal atoms alone on the matrix or filler represents the maximum utilization of atoms at the presentstage, which has unique coordination properties, active sites, and synergistic effects with the support. Compared with traditional fillers, single-atom fillers not only have the advantages of supporting fillersbut can also provide monatomic metals to form passivation films, promote the progress of catalytic passivationreactions, and combine organic compounds to generate new composite materials. This paperfocuses on the preparation methods and mechanisms of single-atom coatings in the field of batteriesand catalysts as well as the application of composite materials prepared by combining single-atom materialswith polymer matrices in the field of metal protection. The preparation methods, application prospects,and coating characteristics of various single-atom composites were summarized. In addition,we discuss the potential applications of single-atom coatings in the design of future composite coatings.

Copper-based catalysts are widely used in methanol synthesis, selective catalytic reduction of NOx,hydrogenation, dehydrogenation and hydrogenolysis reactions. In this work, a series of Cux/Zn3 0.5xMg3 0.5xAl2O9 x catalysts were prepared via the controlled calcination and reduction ofhydrotalcite-like structured CuxZn3 0.5xMg3 0.5xAl2(OH)16CO3 precursors. The formation process of Cu2/Zn2Mg2Al2O7 from Cu2Zn2Mg2Al2(OH)16CO3 was characterized via several techniques. Characterizationsresults indicated that the dispersion of Cu in reduced Cu2/Zn2Mg2Al2O7 reached 79.3%, and it exhibitedexcellent activity for the dehydrogenation of 1,4-butanediol (1,4-BDO) to c-butyrolactone (GBL). Thedetected conversion of 1,4-BDO reached 99.2% with a 99.5% selectivity of GBL at 240 C, 0.1 MPa andLHSV 1 = 0.13 h, and the calculated productivity of GBL was 7.07 g-GBL/g-cat/h. And Cu2/Zn2Mg2Al2O7could maintain its activity within 50 h on stream.

Investigation lateral deformation and failure characteristics of strip coal pillar in deep mining
Chen, Shaojie,Qu, Xiao,Yin, Dawei,Liu, Xingquan,Ma, Hongfa,Wang, Huaiyuan Techno-Press 2018 Geomechanics & engineering Vol.14 No.5
In deep mining, the lateral deformation of strip coal pillar appears to be a new characteristic. In order to study the lateral deformation of coal-mass, a monitoring method and monitoring instrument were designed to investigate the lateral deformation of strip coal pillar in Tangkou Coalmine with the mining depth of over 1000 m. Because of without influence of repeated mining, the bedding sandstone roof is easy to break and the angle between maximum horizontal stress and the roadway is small, the maximum lateral deformation is only about 287 mm lower than the other pillars in the same coalmine. In deep mining, the energy accumulation and release cause a discontinuous damage in the heterogeneous coal-mass, and the lateral deformation of coal pillar shows discontinuity, step and mutation characters. These coal-masses not only show a higher plasticity but also the high brittleness at the same time, and its burst tendency is more obvious. According to the monitoring results and theoretical calculations, the yield zone of the coal pillar width is determined as 15.6 m. The monitoring results presented through this study are of great significance to the stability analysis and design of coal pillar.

Effects of Electric Filed on Electrospray Process: Experimental and Simulation Study
Xuan Dong,Yuansheng Zheng,Binjie Xin,Huaiyuan Liu,Lantian Lin 한국섬유공학회 2020 Fibers and polymers Vol.21 No.11
At present, there exists a widely-held view that electric field plays an extremely important role in the electrosprayprocess. Aimed at investigating into the effects of electric field distribution and intensity on the electrospray process andresultant microsphere diameter, a variety of necessary and relevant tests were performed in this study by inviting an auxiliaryelectrode ring. The three-dimensional electric fields of the electrospray system were simulated, in addition, high-speedphotography was adopted to recognize the electrospray modes. The results of a series of electrospray experiments demonstratedthat not only electrospray mode but also resultant microsphere diameters are influenced, to a considerable degree, by the electricfield. Such simulation results were verified by above-mentioned experiments that from higher electric field intensity comessmaller microsphere diameter, due to the fission caused by the surface charge, and besides, more uniform electric fielddistribution produces more uniform microsphere diameter.
