Applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 177-192页

This paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrotactic microorganisms towards a curved oscillatory surface. The influence of magnetic fields is also inspected in terms of their physical characteristics. To depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and homogeneous chemical reactions are also incorporated. Utilizing a curvilinear coordinate system, the flow problem is formulated as partial differential equations(PDEs)for momentum, concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAM).The effects of significant flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and temperature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and temperature fields are enhanced as the values of the solid volume fraction variables *** is also verified that the concentration rate field decreases as the values of the homogeneous reaction strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous reaction strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

Constructing nitrided aluminum metal skeleton to improve the reversibility and cyclicity of Si film electrode

引用

Progress in Natural Science:Materials International 2023年第6期33卷 789-796页

作者： Jiali Tong Tingfeng Guan Qilin Tong Yan Cheng Zhaozhe Yu Guilin University of Electronic technology Guangxi Key Laboratory of manufacturing Systems and advanced manufacturing technology

Silicon is a promising anode material for lithium-ion batteries(LIBs) due to its high theoretical capacity, low discharge potential, environmental friendliness and cost-effectiveness. However, its low conductivity, high volume variation and poor cycling performance hamper its practical application. Herein, we prepare Si-Al(Al N)composite film anodes containing a nitrided aluminum metal conductive skeleton. The Al(Al N) creates a multiphase interface, buffers the volume expansion of the electrode, and also plays a role in conducting electricity and supporting the electrode structure. As a result, the Si-Al(Al N) electrode exhibits excellent performance with a high initial coulombic efficiency of 86 %, an outstanding cycling stability of roughly 1955 m Ah g-1after 200 cycles at420 m A g-1and retains 916 m Ah g-1after 300 cycles even at 4200 m A g-1(the capacity retention rate of 83 %).This work provides an effective method for adjusting anode performance with greater freedom.

Unraveling the impacts of intermolecular interaction on morphology evolution for highly efficient organic solar cells and modules

Understanding the effect of intermolecular interaction on the growth dynamic of active layers is critical for advancing organic solar cells(OSCs). However, the diverse structure of donors and acceptors makes the research challenging. Additives with customizable structures and properties could simplify this complexity. Herein, we meticulously tailor two additives of 3,4-ethylenedioxythiophene(EDOT) and 2,5-dibromo-3,4-ethylenedioxythiophene(DBEDOT), possessing distinct intermolecular interaction features to elaborate the inherent relationship. It is found that varied interaction strengths can alter film formation processes. The enhanced intermolecular interaction between the DBEDOT and non-fullerene acceptor BTP-e C9-4F results in pre-aggregation and longer crystallization duration of BTP-e C9-4F, facilitating the formation of films with compact molecular packing and decent phase separation. Thus, exciton dissociation and charge transport become more efficient. Finally, devices processed with DBEDOT exhibit a remarkable power conversion efficiency of 19.35% in small-area OSCs and 14.11% in bladecoated 5 cm × 5 cm organic solar mini-modules. Especially, OSCs can maintain 80% of their initial efficiency after continuous annealing at 85 °C for over 2,100 h.

Effect of pre-recovery on microstructure and properties of rolled Al-12.18Zn-3.31Mg-1.43Cu-0.20Zr-0.04Sr aluminum alloy

引用

International Journal of Minerals,Metallurgy and Materials 2019年第2期26卷 241-250页

作者： Cheng-bin Cai Xiao-jing Xu Jin-dong Huang Shi-hao Ju Qing Ding Cheng-song Wang Engineering Institute of advanced manufacturing and Modern Equipment technology Jiangsu University

The independently designed and manufactured ultra-high-strength aluminum alloy Al-12.18 Zn-3.31 Mg-1.43 Cu-0.20 Zr-0.04 Sr was investigated via scanning electron microscopy observations, X-ray diffraction analysis, hardness tests, electrical conductivity tests, tensile tests, intergranular corrosion tests, and exfoliation corrosion tests. The effect of pre-recovery on the microstructure and mechanical properties of this aluminum alloy was also studied. The results show that the pre-recovery heat treatment releases deformation energy, inhibits recrystallization, and decreases the dislocation density. Although the pre-recovery heat treatment has little effect on the hardness, electrical conductivity, and elongation of this aluminum alloy, it can dramatically improve the alloy's tensile strength(the maximum tensile strength increased from 785.0 MPa to 809.2 MPa). Moreover, the tensile properties of this aluminum alloy have a certain degree of isotropy, and the pre-recovery heat treatment does not affect this property. In addition, the rolled aluminum alloy exhibits good corrosion resistance, but the effect of the pre-recovery heat treatment on the alloy's resistance to intergranular and exfoliation corrosion is negligible.

Inventory control model based on external and interior reverse logistics

引用

Journal of Harbin Institute of technology(New Series) 2009年第5期16卷 717-722页

作者：董景峰王刚吕民高国安 advanced manufacturing technology Center Harbin Institute of Technology

To improve the inventory control strategy for enterprise and optimize inventory control parameters of existing external and interior reverse logistics, a multi-resource inventory control model is proposed to better simulate the logistics fact, which is aimed at periodic inventory checking and pull mode of inventory control strategy, based on the return product arrival time obeying Poisson distribution, the return product employing lotsize process and the nonzero lead time of manufaeturinge/remanufacturing. The rational cost function with multiple constraints is employed to describe the inventory model. The genetic algorithm is employed to solve the inventory cost function to obtain the optimal solution of inventory checking periods, safe inventory point, product lot-sizes and process lot-sizes of return product. An example is presented to prove the feasibility and validity of the proposed method. Moreover, the influence of manufacturing/remanufacturing lead time and reuse rate of return production on the inventory control strategy of enterprise is analyzed.
