| 1 | Floc structure and membrane fouling affected by sodium alginate interaction with Al species as model organic pollutants显示文摘Membrane filtration combined with pre-coagulation has advantages in advanced wastewater treatment. As a model of a microbial polysaccharide, research on the effect of sodium alginate(SA) on alum hydrolysis has been rare; therefore, it is necessary to gain insight into the interface interaction between SA molecules and Al species, and the role SA plays during floc formation. In this study, the interaction mechanism between SA and Al species has been investigated, by evaluating the effect of SA on floc characteristics and membrane fouling during coagulation–ultrafiltration with different Al species coagulants(AlCl3 and preformed Al13). Al 2 p X-ray photoelectron spectroscopy(XPS) confirmed that the complexation of ligands and Al species strongly affects the reaction pathways for Al hydrolysis and the final nature of the flocs, as Al13 can be decomposed into octahedral precipitates when SA is added. The presence of SA can affect floc properties, which have important impacts on the characteristics of the cake layer and membrane fouling. Due to the bridging ability of SA, the floc strength increased by about 50% using Ala, which was much better than preformed Al13, with a percentage increase of only about 6%. Moreover,the recovery factor of HA-flocs was decreased from 96% to 43% with SA addition of 0.5 mg/L.It was concluded that SA can affect the characteristics of the cake layer and membrane fouling through participating in the formation of primary flocs and altering the Al hydrolysis pathway. | Xuejun Xiong Hui Xu Beiping Zhang Xiaohui Wu Hongyan Sun Dongsheng Wang Zhengyang Wang | 2019 | Journal of Environmental Sciences2019，31，8： | 3 |
| 2 | Particles in composite polymer electrolyte for solid-state lithium batteries:A review显示文摘Solid-state lithium batteries(SSLBs)have been identified as one kind of the most promising energy conversion and storage devices because of their safety,high energy density,and long cycling life.The development of solid-state electrolyte is vital to commercialize SSLBs.Composite polymer electrolyte(CPE),derived by compositing inorganic particles into solid polymer electrolyte has become the most practical species for SSLBs because it inherits the advantages of polymer electrolyte and simultaneously achieves enhanced ionic conductivity and mechanical properties.The characteristics of inorganic particles and their interaction with polymers strongly impact the performance of CPE,improving its ionic conductivity,mechanical properties,thermal and electrochemical stability,as well as interface compatibility with both electrodes.In this review,the effects of particle characteristics including its species,size,proportion,morphology on the ionic conductivity and mechanical properties of CPE are reviewed.Meanwhile,some novel composite strategies are also introduced including surface modification,hybridization,and alignment of particles in polymer matrices,as well as some new preparation methods of CPE.The interactions between particles and other components in CPE including polymer matrices or lithium salt are particularly focused herein to reveal the lithium conductive mechanism.Finally,a perspective on the direction of future CPE development for SSLBs is presented. | Nan Meng Xiaogang Zhu Fang Lian | 2022 | Particuology2022，20，1： | 3 |
| 3 | Numerical study on shock-accelerated heavy gas cylinderswith diffusive interfaces显示文摘Interactions of shock wave and heavy gas cylinders with different diffusive interfaces are numerically investigated. Comparisons among these interfaces are made in terms of cylinder morphology, wave system evolution, fluids mixing, and circulation generation. Navier-Stokes equations are solved in the present work to simulate the complex multi-fluid flow. The fifth-order weighted essentially non-oscillatory scheme is used to compute the numerical flux. The influence of interface diffusion is revealed by the numerical results. The cylinders with similar geometric scale but different diffusion interface have great similarities in the hydrodynamic characteristics, including the interface morphology, shock focusing and molecular mixing, as well as circulation deposition. For the cases with more serious interface diffusion, the cylinder develops into more regular vortex pairs. The diffusive interface greatly mitigates the strength of the reflected shock wave and weakens the shock focusing capability. Some interface structural features are also recorded and analyzed. The diffusive interface brings about slower molecular mixing and less circulation generation. The circulation deposition on different interfaces is quantitatively investigated and compared with the theoretical models. The theoretical models are found to be applicable to the scenarios of diffusive interfaces. | Dongdong Li Ben Guan Ge Wang | 2019 | Acta Mechanica Sinica2019，35，4： | 2 |
| 4 | Transport diffuse interface model for simulation of solid-fluid interaction显示文摘For solid-fluid interaction, one of the phase-density equations in diffuse interface models is degenerated to a '0 = 0' equation when the volume fraction of a certain phase takes the value of zero or unity. This is because the conservative variables in phasedensity equations include volume fractions. The degeneracy can be avoided by adding an artificial quantity of another material into the pure phase. However, nonphysical waves,such as shear waves in fluids, are introduced by the artificial treatment. In this paper,a transport diffuse interface model, which is able to treat zero/unity volume fractions, is presented for solid-fluid interaction. In the proposed model, a new formulation for phase densities is derived, which is unrelated to volume fractions. Consequently, the new model is able to handle zero/unity volume fractions, and nonphysical waves caused by artificial volume fractions are prevented. One-dimensional and two-dimensional numerical tests demonstrate that more accurate results can be obtained by the proposed model. | Li LI Qian CHEN Baolin TIAN | 2019 | Applied Mathematics and Mechanics(English Edition)2019，40，3： | 1 |
| 5 | THE INTERACTION PROBLEM BETWEEN THE ELASTIC LINE INCLUSIONS显示文摘Using the engineering model of elastic line inclusion and the basic solutions of a single inclusion, the interaction problem between line inclusions in an elastic solid was investigated. A set of standard Cauchy-type singular equations of the problem was presented. The stress intensity factors at points of inclusions and the interface stresses of two sides of the inclusion were calculated. Several numerical examples were given. The results could be regarded as a reference to engineering. | 陶昉敏 张明焕 汤任基 | 2002 | Applied Mathematics and Mechanics(English Edition)2002，23，4： | 0 |

| 7 | Interface interaction and inter-osmosis effect of Fe_x (SiO_2)_(1-x) nanocomposite materials on magnetic properties显示文摘Fex(SiC2 )1 - x nanocomposites prepared by using mechanical alloying method were reported. The mi-crostructure character and magnetic properties of Fex (SiO2) 1 - x nanocomposite samples with different Fe content and different ball milling time were studied by using X-ray diffraction (XRD), transmission electron microscopy (TEM), Mossbauer spectroscopy, and Faraday magnetic balance in a wide temperature range. The results indicate that the mi-crostructure and magnetic properties are closely related to ball milling time and Fe content. When Fe content is less than 20 wt% , the sample after 80-h ball milling has very complex microstructure. Small α-Fe grains and Fe cluster are implanted in SiO2 matrix. And there are not only isolated α-Fe granular and Fe cluster, but also nanometer scaled sandwich network-like structure. Fex (SiO2) 1 - x nanocomposite samples display a rich variety of physical and chemical properties as a result of their unique nanostructure, strong interface interaction and | 熊永红 熊曹水 李铁 李玉芝 王德兴 | 1999 | Science China Mathematics1999，42，2： | 0 |

| 10 | Interaction behaviors between Zn-Al alloy and Al_2O_3p/6061Al composite with aid of ultrasonic vibration显示文摘Interactions between Zn-Al alloy and Al2O 3p/6061Al composite with the aid of ultrasonic vibration in air were investigated. For the composite without degassed treatment, the molten Zn-Al alloy cannot spread along the surface of the composite when the ultrasonic vibration amplitude is lower than 10μm. Instead, it undermines the substrate oxide layer and propagates along the substrate metal-substrate oxide interface, and penetrates into the composite at the same time. The penetration of the Zn-Al alloy into the composite makes the microstructure of the penetration zone unconsolidated. As the ultrasonic vibration amplitude increases, the spreading area of the molten Zn-Al alloy increases and the mass transfer at the interaction interface between the Zn-Al alloy and the composite intensifies. The porosity at the interaction interface results from the gas escaping from the base material by which the undermining phenomenon and the penetration of elements Zn, Cu into the composite is favoured. When the composite is degassed, the undermining zone and the penetration zone become significantly limited and the penetration zone remains consolidated. Only limited base metal melts during interaction, which is accompanied with fewer reinforcements and primary α-Al dendrites in the solidified Zn-Al alloy. | 许志武 闫久春 孔祥利 杨士勤 | 2005 | 中国有色金属学会会刊:英文版2005，15，S2： | 0 |
