Flotation is an efficient pre-treatment technology for oily water.In this work,the interaction process between the moving oil droplet and the gas bubble was studied by high-speed camera and Bassset-Boussinesq-Oseen(BBO)theoretical model,and the experimental and simulation results of the oil droplet trajectory were compared.Moreover,the micro-particle image velocimetry system was utilized to observe the flow inside and outside of the moving oil droplet.The results show that the BBO model with the mobile bubble’s surface can reflect the velocity change trend of the oil droplet during the interaction process between the moving oil droplet and the gas bubble,but there are some significant differences between the experimental and simulation results.While the oil droplet is moving on the bubble’s surface,the velocity of the area near the contact point of oil droplet–gas bubble is less than that of the other areas inside the oil droplet.Meanwhile,the flow of water above the oil drop is more biased towards the gas bubble.

Lithium-sulfur batteries(LSBs) are regarded as a competitive next-generation energy storage device.However, their practical performance is seriously restricted due to the undesired polysulfides shuttling.Herein, a multifunctional interlayer composed of paper-derived carbon(PC) scaffold, Fe3O4 nanoparticles,graphene, and graphite sheets is designed for applications in LSBs. The porous PC skeleton formed by the interweaving long-fibers not only facilitates fast transfer of Li ions and electrons but also provides a physical barrier for the polysulfide shuttling. The secondary Fe3O4@graphene component can reduce the polarization, boost the attachment of polysulfides, and promote the charging-discharging kinetics. The outer graphitic sheets layers benefit the interfacial electrochemistry and the utilization of S-containing species.The efficient obstruction of polysulfides diffusion is further witnessed via in situ ultraviolet-visible characterization and first-principles simulations. When 73% sulfur/commercial acetylene black is used as the cathode, the cell exhibits excellent capacity retention with high capacities at 0.5 C for 1000 cycles and even up to 10 C for 500 cycles, an ultrahigh rate capability up to 10 C(478 m Ah g-1), and a high arealsulfur loading of 8.05 mg cm-2. The strategy paves the way for developing multifunctional composites for LSBs with superior performance.

Effectively capturing volatile radioiodine generated during the nuclear fission process is considered to be a safe way to the utilization of nuclear power. Here we report a new two-dimensional covalent organic framework(2D COF), ETTA-PyTTA-COF, as a highly efficient iodine adsorbent, which is constructed through the condensation reaction between 4,4’,4’’,4’’’-(ethene-1,1,2,2-tetrayl)-tetrabenzaldehyde(ETTA) and 1,3,6,8-tetrakis(4-aminophenyl)pyrene(PyTTA). The ETTA-PyTTA-COF possesses a permanent 1D channel porous structure with a high Brunauer-Emmet-Teller(BET) surface area of 1519 m2/g and excellent chemical and thermal stability. It shows ultrahigh iodine adsorption capability, which can reach up to 4.6 g/g in vapor owing to its high BET surface area, large π-conjugated structure and plenty of imine groups in the skeleton of the COF as effective iodine sorption sites.

Counterfeit leather products infringe the intellectual property rights of the business,cause enormous economic loss,and negatively influence the business enthusiasm for innovation.However,traditional anti-counterfeiting materials for leather products suffer from complicated fabrication procedures,photobleaching,and high volatile organic com-pound(VOC)emissions.Here,a sustainable and invisible anti-counterfeiting ink composed of waterborne polyure-thane and water-dispersible lanthanide-doped upconversion nanoparticles(UCNPs)featuring ease of preparation,high photostability,non-toxicity,low VOC emissions,and strong adhesion strength for leather products is designed and synthesized.After decorating on the surface of leather products,the obtained patterns are invisible under normal light conditions.Upon irradiation at 808 nm,the invisible patterns can be observed by naked eyes due to the visible light emitted by 808 nm excited UCNPs.Our approach described here opens a new pathway to realize the long-term,stable anti-counterfeiting function of leather products.

SnAgCu solder system with the addition of rare earth Ce, which has better thermo-mechanical properties compared to those of SnPb solder, is regarded as one of the promising candidates for electronic assembly. Moreover, the SnAgCuCe solder alloys can provide good quality joints with Cu substrates. However, there is few report of the constitutive model for SnAgCu solder bearing micro-amounts rare earth Ce. In this paper, the unified viscoplastic constitutive model, Anand equations, is used to represent the inelastic deformation behavior for SnAgCu and SnAgCuCe solders. In order to obtain the acquired data for the fitting of the material parameters of this unified model, a series of experiments of constant strain rate test were conducted under isothermal conditions at different temperatures. The Anand parameters of the constitutive equations for SnAgCu and SnAgCuCe solder were determined from separated constitutive relations and experimental results. Nonlinear least-square fitting was selected to determine the model constants. And the simulated results were then compared with experimental measurements of the stress-inelastic strain curves： excellent agreement was found. The model accurately predicted the overall trend of steady-state stress-strain behavior of SnAgCu and SnAgCuCe solders for the temperature ranges from 25℃ to 150 ℃, and the strain rate ranges from 0.01 s^-1 to 0.001 s ^-1. It is concluded that the Anand model can be applied for representing the inelastic deformation behavior of solders at high homologous temperature and can be recommended for finite element simulation of the stress-strain response of lead free soldered joints. Based on the Anand model, the investigations of thermo-mechanical of SnAgCu and SnAgCuCe soldered joints in fine pitch quad flat package by finite element code were done under thermal cyclic loading, it is found that the reliability of SnAgCu soldered joints can be improved remarkably with addition of rare earth Ce. The results may provide a theory guide for developing constitu

For the high temperature coefficient of resistivity (TCR) of VO_x thin films,the preparation process including the heat-treating and the application of seed layer,has been investigated.When the films were prepared without a seed layer, heated in air for 2 h,and then in N_2 for 2 h at 470℃,the TCR of about 1.07% K^(-1) (3.75% K^(-1) at 45℃～65℃) was gained.The R_(20℃)/R_(100℃) was about 28.75,while the R_(20℃)/R_(100℃) of the thin films prepared on a seed layer was 5.5.The X-ray diffraction (XRD) showed that better heating conditions led to less phase compositions and higher V_2O_5 diffraction peak,which led to higher TCR.The experiment results showed that the optimum heating condition was at 470℃for 4 h.

南通植物园温室整体建筑造型优雅、轻盈,结构体系为扭转空间刚架结构。通过采用MIDAS/Gen软件对扭转空间刚架结构进行整体空间分析,并对屋面复杂关键节点进行细致有限元分析,给节点设计提供分析数据依据。因建筑造型需要,刚架纵向无法设置交叉支撑,将屋面幕墙系统设计为结构纵向传力体系,为刚架提供纵向刚度,同时使得结构具有更好的抗震性能。多榀刚架因杆件尺寸各不相同,同时空间角度扭转,施工吊装存在一定的风险,通过施工工况验算,给出吊装时注意事项,对现场刚架吊装工况提出指导性意见,保证工程顺利安装完成。
