A novel high temperature oxidation precipitation method for synthesizing high-purity nano-sized ferric phosphate was proposed. We systematically investigated the impact of reaction temperature on the properties of the ferric phosphate product and its slurry. The study found that the FePO₄ obtained by the high-temperature precipitation method consisted of amorphous nanoparticles with a narrow size distribution around 30 nm. Increasing the reaction temperature did not affect the purity or crystal structure of the particles, but it reduced the viscosity and solid content of the slurry, beneficial for improving the solid-liquid separation efficiency in subsequent production processes. Characterization of products obtained at different reaction temperatures using FTIR, XPS, and ICP-OES revealed that elevated temperatures decreased the content of hydroxyl groups on the surface of the ferric phosphate particles, weakening the adsorption of metal ion impurities on the particle surface and the interaction between particles. The LiFePO₄@C material synthesized using the nano FePO₄ product obtained by the high-temperature oxidative precipitation method as a precursor exhibited good rate performance (137.1 mAh g⁻¹ at 5 C). This high-temperature oxidative precipitation method might enable controllable, continuous, and easily scalable production of nano-sized FePO₄ production.

提出了一种高温氧化沉淀法合成高纯度纳米磷酸铁的新方法。系统地研究了反应温度对磷酸铁产品及其浆料性能的影响。研究发现，高温沉淀法制备的FePO4由非晶纳米颗粒组成，粒径分布在30 nm左右。提高反应温度不影响颗粒的纯度和晶体结构，但降低了料浆的粘度和固含量，有利于在后续生产工艺中提高固液分离效率。利用FTIR、XPS和ICP-OES对不同反应温度下得到的产物进行表征，发现温度升高降低了磷酸铁颗粒表面羟基的含量，减弱了金属离子杂质在颗粒表面的吸附和颗粒间的相互作用。以高温氧化沉淀法得到的纳米FePO4产物为前驱体合成的LiFePO4@C材料具有良好的速率性能（5℃时为137.1 mAh g−1）。这种高温氧化沉淀法可以实现可控、连续和易于扩展的纳米FePO4生产。

O3-type layered oxides are among the most promising cathode candidates for sodium-ion batteries, yet their practical use is constrained by irreversible oxygen redox at high voltages, parasitic side reactions, and pronounced moisture sensitivity. Here, we propose a one-step H₃BO₃ treatment that introduces an in-situ boride complex, enabling near-surface B doping and the formation of a conformal sodium borate interphase. The dual modification operates synergistically: B incorporation reinforces the layered framework and suppresses oxygen redox above 4.0 V, while the sodium borate layer, endowed with high Na⁺ conductivity, functions as a robust interfacial barrier. These effects collectively suppress transition-metal dissolution, mitigate electrolyte decomposition, and promote rapid Na⁺ transport. Benefiting from this design, the optimized cathode delivers 160.5 mAh g⁻¹ at 0.1C and retains 85.3 % capacity after 200 cycles at 1C. Moreover, the sodium borate coating effectively blocks H⁺/H₂O ingress, conferring exceptional air stability. After 150 cycles, 3-days-aged pristine cathode retains 4.7 % of the fresh capacity, whereas optimized cathode maintains nearly pristine cycling stability. Even after seven days of exposure, only trace Na₂CO₃ impurities are detected. This work establishes in situ boride complexes as a viable strategy to achieve electrochemically robust and moisture-tolerant sodium-ion cathodes for grid-scale energy storage.

o3型层状氧化物是钠离子电池最有前途的阴极候选材料之一，但其实际应用受到高压下不可逆氧氧化还原、寄生副反应和明显的水分敏感性的限制。在这里，我们提出了一步H3BO3处理，引入原位硼化物配合物，使近表面B掺杂和形成保形硼酸钠界面相。这两种修饰协同作用：B的掺入强化了层状框架并抑制4.0 V以上的氧氧化还原，而硼酸钠层具有高Na+导电性，可作为坚固的界面屏障。这些效应共同抑制过渡金属溶解，减缓电解质分解，促进Na+快速运输。得益于这种设计，优化后的阴极在0.1C时提供160.5 mAh g - 1，在1C下循环200次后保持85.3%的容量。此外，硼酸钠涂层有效地阻止H+/H2O的进入，赋予卓越的空气稳定性。经过150次循环后，3天老化的原始阴极保留了4.7%的新容量，而优化后的阴极保持了近乎原始的循环稳定性。即使在暴露7天后，也只检测到微量的Na2CO3杂质。这项工作建立了原位硼化物复合物作为一种可行的策略，以实现电化学稳健和耐湿的钠离子阴极，用于电网规模的储能。

In particle systems, understanding mechanical interactions between particles is fundamental for accurately predicting material behavior under various conditions, especially when cohesive forces play a critical role. The Discrete Element Method (DEM) is able to model these interactions based on material as well as contact properties. This paper evaluates the accuracy of DEM in predicting material behavior, for which a cost-effective cohesion model is implemented within an in-house DEM code. Simulations of wooden particles in a shear cell, with and without grease coating, are able to replicate the corresponding experimental results. The addition of the cohesion model results in a negligible increase in computational effort, which is of key importance for its application to larger systems.

It is evident that oxygen carriers play a pivotal role in the chemical looping combustion. Although the majority of studies have concentrated on enhancing the high-temperature thermal stability and reactivity of oxygen carriers, it is imperative to study the attrition behaviors of oxygen carriers precisely. In this work, a micro fluidized bed thermogravimetric analysis (MFB-TGA) was developed to obtain the attrition properties through real-time measurement of weight changes during the redox reactions. Ilmenite, iron ore, and laterite ore were selected as the oxygen carriers, and the contributions of mechanical, thermal, and chemical stresses to oxygen carrier attrition were investigated. It was found that ilmenite and iron ore started stable attrition just after the 20th and 5th cycles due to the activation phenomenon. Laterite ore suffered a fast attrition stage with a rate of 0.37 % h⁻¹ before the 20th cycle, after that, the attrition rate changed to be slow. At the end of activation, ilmenite and iron ore attrition was led by mechanical stress with the proportion of ∼40 %, while chemical stress was the predominant factor of laterite ore attrition with the proportion of ∼57.6 %. The proposed micro fluidized bed thermogravimetric method provides an effective and convenient pathway to determine, evaluate, and compare the attrition behavior of oxygen carriers in laboratory.

可见，氧载体在化学环燃烧中起着举足轻重的作用。虽然大多数研究都集中在提高氧载体的高温热稳定性和反应性上，但对氧载体的磨损行为进行精确的研究是势在必行的。本文采用微流化床热重分析（MFB-TGA）技术，实时测量氧化还原反应过程中重量的变化，从而获得材料的磨损特性。选取钛铁矿、铁矿和红土矿作为氧载体，研究了机械应力、热应力和化学应力对氧载体磨损的影响。在第20和第5次循环后，钛铁矿和铁矿由于活化现象开始稳定磨耗。第20循环前，红土矿进入快速磨矿阶段，磨矿速率为0.37% h−1，之后磨矿速率逐渐变缓。活化结束时，钛铁矿和铁矿的磨损以机械应力为主，占比约为40%，而红土矿的磨损以化学应力为主，占比约为57.6%。所提出的微流化床热重法为实验室中氧载体的磨损行为的测定、评价和比较提供了一种有效、便捷的途径。

The Discrete Element Method (DEM) stands out as an effective computational tool for modeling complex mechanical wear processes such as solid particle erosion. The DEM method offers significant advantages in terms of providing realistic results, particularly when it comes to examining particle and surface interactions over time and predicting surface deformations. In this study, the effectiveness of DEM in determining the solid particle erosion wear behavior was evaluated by comparing it with experimental data. In the experimental phase, aluminum oxide (Al₂O₃) particles were impacted onto St37 structural steel samples at different impact angles (30°, 60°, 90°) and different quantities (1, 2, 3 kg) to calculate erosion rates. DEM based simulation analyses were performed using the same parameters, and surface deformations were modelled. When compared with experimental data, the simulation results showed high convergence, particularly at high impact angles such as 60° and 90° (5–15 % deviation). However, deviations increased at low impact angles such as 30°. While DEM analyses can successfully predict surface embedment deformations, they have not been able to adequately reflect damage caused by ductile behavior such as sliding. The surface embedment effect has shown a similarity of around 5 % at high impact angles compared to experimental data. In addition, ANOVA tests were applied to the erosion rates found in experiments and simulations to statistically evaluate the results. The test results statistically revealed that the most effective variable on the erosion rate was the angle of impact (p < 0.0001). The results demonstrate that the discrete element method is a reliable approach for modeling solid particle erosion wear behavior and, when used in conjunction with experimental data, can provide effective solutions for predicting and preventing erosion-induced damage during the design phase in systems such as jet engine turbines, space applications, and dust particle interaction engineering problems.

离散元法（DEM）作为模拟复杂机械磨损过程（如固体颗粒侵蚀）的有效计算工具而脱颖而出。DEM方法在提供逼真的结果方面具有显著的优势，特别是在检测颗粒和表面相互作用以及预测表面变形时。在本研究中，通过与实验数据的对比，评估了DEM在确定固体颗粒冲蚀磨损行为方面的有效性。在实验阶段，氧化铝（Al2O3）颗粒以不同的冲击角度（30°、60°、90°）和不同的数量（1、2、3 kg）冲击St37结构钢样品，计算侵蚀速率。使用相同的参数进行基于DEM的仿真分析，并对表面变形进行建模。与实验数据相比，仿真结果具有较高的收敛性，特别是在大冲击角（如60°和90°）（偏差5 - 15%）时。然而，在低冲击角度（如30°）时，偏差增加。虽然DEM分析可以成功地预测表面嵌入变形，但它们不能充分反映由滑动等延性行为引起的损伤。在大冲击角下，表面嵌入效应与实验数据的相似性约为5%。此外，对实验和模拟得到的侵蚀速率进行了方差分析，对结果进行了统计评价。试验结果统计显示，对冲蚀率影响最大的变量是冲击角（p < 0.0001）。结果表明，离散元方法是模拟固体颗粒侵蚀磨损行为的可靠方法，当与实验数据结合使用时，可以为喷气发动机涡轮、空间应用和粉尘颗粒相互作用工程等系统的设计阶段预测和预防侵蚀引起的损伤提供有效的解决方案。

This study investigates the asymmetrical arching phenomenon in inclined granular deposits by performing the DEM simulations of trapdoor tests. The results indicate that the weakest arching effect occurs at deposit inclination angles of 30° ∼ 45°, evidenced by the highest arching ratio on the trapdoor, largest deposit settlement, and lowest fabric anisotropy intensity. The asymmetrical arching effect is manifested by lower arching ratios, greater deposit settlements and larger fabric anisotropy magnitudes on the left part beside the trapdoor compared to the right part. The arching asymmetry depends on the angle Ψ formed between the potential failure plane's orientation and the deposit inclination direction, and this angle (Ψ_L) for region L is on average lower than that (Ψ_R) for region R. A larger Ψ_R leads to a more notable inter-particle locking effect and a higher resistance to deformation for region R, which further causes larger arching ratios and less remarkable deposit settlements. Moreover, the arching asymmetry degree is positively correlated with the discrepancy between Ψ_L and Ψ_R. The disparity of mechanical responses between regions L and R aggravates with increasing Ψ_R – Ψ_L, and the strongest asymmetrical arching effect occurs around θ = 30°, where Ψ_R – Ψ_L takes the maximum value.

通过活动门试验的DEM模拟，研究了倾斜粒状矿床中的不对称拱拱现象。结果表明，沉积物倾角为30°~ 45°时，成拱效应最弱，活动门上的成拱率最高，沉积物沉降量最大，织物各向异性强度最低。不对称拱拱效应表现为：活板门左侧拱拱比较低，沉降量较大，织物各向异性量级较大。拱起不对称性取决于潜在破坏面方向与沉积物倾斜方向之间形成的夹角Ψ，其中L区（ΨL）平均小于R区（ΨR）。ΨR越大，R区颗粒间锁紧效应越显著，抗变形能力越强，从而导致拱起比越大，沉积物沉降不显著。弓形不对称程度与ΨL和ΨR的差异呈正相关。随着ΨR ~ ΨL的增大，L区域和R区域之间的力学响应差异增大，不对称拱效应在θ = 30°附近最强，ΨR ~ ΨL处最大。

This paper introduces the advanced MP-PIC-VOF model tailored for dense particle-laden flows with free surface, which has been developed and extensively tested across a set of validation cases found in literature and original bulk particle water entry case. A distinctive feature of the MP-PIC method is its demonstrated ability to accurately capture the behavior of closely packed particles in a fluid, even in the absence of direct pairwise particle-particle interactions. At a closed packed limit, the MP-PIC method achieves the accurate representation of the state through the resolved mean particle velocity field and implementation of the velocity limiter in the inter-particle stress force. The new model integrates a trilinear interpolation technique, specifically adapted for unstructured hexahedral meshes, and a weighted least squares method for efficient gradient computation that operates at a sub-cell level, enabling more accurate calculation of inter-particle stress gradients. Other key contributions include the integration of hydrostatic pressure adaptation in the momentum equation and a volume-conservative alpha transport equation that ensures mass conservation during the transfer of the solid phase between distinct fluid phases. The coupling framework includes a range of coupled fluid-particle forces important for particles immersed in liquid, including a dense virtual mass force. The model's validation against experimental data and CFD-DEM-VOF results focuses on key flow parameters, specifically particle velocity, dispersion profile, and cavity evolution during bulk particle water entry. The model is shown to accurately simulate complex solid-liquid-gas interactions, demonstrating its potential for optimizing a wide range of complex industrial processes such as liquid fluidized beds, solid-liquid stirred tanks, and clarifiers.

本文介绍了先进的MP-PIC-VOF模型，该模型专为自由表面的密集颗粒负载流量身定制，该模型已经开发并在一系列文献中发现的验证案例和原始的大块颗粒水进入案例中进行了广泛的测试。MP-PIC方法的一个显著特点是，即使在没有直接成对粒子-粒子相互作用的情况下，它也能准确捕捉流体中紧密堆积的粒子的行为。在封闭填充极限下，MP-PIC方法通过解析平均粒子速度场和在粒子间应力中实施速度限制器来实现状态的精确表示。新模型集成了专门适用于非结构化六面体网格的三线性插值技术，以及在亚单元水平上进行有效梯度计算的加权最小二乘法，从而可以更准确地计算颗粒间应力梯度。其他重要贡献包括在动量方程中整合静水压力适应，以及一个体积保守的α输运方程，该方程确保了固体相在不同流体相之间传递过程中的质量守恒。耦合框架包括一系列对浸入液体中的粒子很重要的耦合流体-颗粒力，包括密集的虚质量力。根据实验数据和CFD-DEM-VOF结果对模型进行验证，重点关注关键流动参数，特别是颗粒速度、分散剖面和大颗粒水进入过程中的空腔演化。该模型被证明可以准确地模拟复杂的固液气相互作用，展示了其优化各种复杂工业过程的潜力，如液体流化床，固液搅拌槽和澄清器。

At a closed packed limit, the MP-PIC method achieves the accurate representation of the state through the resolved mean particle velocity field and implementation of the velocity limiter in the inter-particle stress force.

Particle size distribution effects on angle of repose measurements remain insufficiently quantified despite their industrial importance. This study systematically investigates friction–polydispersity interactions using PyBullet DEM simulations with factorial design and statistical analysis. Three friction levels (0.3, 0.5, 0.7) and five coefficients of variation (0–100 %) were examined in 750 simulations. Results show that friction is the overwhelmingly dominant factor, explaining 97.7 % of the variance, whereas polydispersity plays a minor but friction-dependent role. Low-friction systems are highly sensitive to size variability, with even modest heterogeneity leading to unstable heaps. In contrast, high-friction systems remain robust, tolerating broad distributions without significant precision loss. The simulated high-friction angles also agree well with theoretical and experimental benchmarks, supporting the model's predictive capability. Overall, the findings establish friction-dependent tolerance criteria for particle size heterogeneity and highlight that accurate friction determination is far more predictive than exhaustive size characterization. These insights provide evidence-based guidelines for granular material handling and quality control in industrial practice.

粒径分布对休止角测量的影响尽管在工业上具有重要意义，但仍然没有充分量化。本研究使用PyBullet DEM模拟、析因设计和统计分析系统地研究了摩擦-多分散性相互作用。在750次模拟中，研究了三种摩擦水平（0.3、0.5、0.7）和五种变化系数（0 - 100%）。结果表明，摩擦是绝大多数的主导因素，解释了97.7%的方差，而多分散性起了一个较小的作用，但依赖于摩擦。低摩擦系统对尺寸变化非常敏感，即使是适度的异质性也会导致不稳定的堆。相比之下，高摩擦系统仍然坚固，可以承受广泛的分布，而不会有明显的精度损失。模拟的高摩擦角与理论和实验基准吻合较好，支持了模型的预测能力。总的来说，研究结果建立了颗粒尺寸非均质性的摩擦相关容差标准，并强调准确的摩擦测定远比详尽的尺寸表征更具预测性。这些见解为工业实践中的颗粒物料处理和质量控制提供了循证指南。

The simultaneous unloading of double material heaps is a common occurrence in industrial workshops. This process causes dust escape to increase due to the interaction of entrained air between material heaps. In order to understand the coupling mechanism, a mathematical and physical model of the simultaneous unloading process of double material heaps is established in this paper. The DEM-CFD coupling method was validated using experimental data. The effects of material heap height, particle velocity and hopper outlet diameter on the entrained air characteristics of double material heap unloading process are analyzed. The “effective entrainment area” index was proposed for the first time to evaluate the coupling mechanism of entrained air between material heaps. The results indicate that: as the height of the material heap increases, the maximum velocity of the entrained air after collision of particles in different cross-sections gradually decreases from 1.4 to 1 m/s. With the increase in particle velocity and hopper outlet diameter, the maximum velocity of the entrained air generated between the material heaps increases. As the heap height, particle velocity, or hopper outlet diameter increases, the rate of change in entrained air velocity gradually decreases. The diameter of the hopper outlet has the greatest effect on the velocity of entrained air at the vertical axis between material heaps. The diameter of the hopper outlet has the most obvious effect on the height of the vortex core, with a maximum height difference of 33 mm. The effective entrainment area increases with heap height, particle velocity, or hopper outlet diameter, reaching a minimum of 568 mm² at 2 m/s and a maximum of 1884 mm² at 30 mm.

双料堆同时卸料是工业车间中常见的现象。由于物料堆之间夹带空气的相互作用，该过程导致粉尘逸出增加。为了理解这种耦合机理，本文建立了双料堆同时卸载过程的数学和物理模型。用实验数据对DEM-CFD耦合方法进行了验证。分析了料堆高度、颗粒速度和料斗出口直径对双料堆卸料过程夹带风特性的影响。首次提出了“有效夹带面积”指标来评价物料堆间夹带空气的耦合机理。结果表明：随着物料堆高度的增加，不同截面颗粒碰撞后夹带空气的最大速度从1.4 m/s逐渐减小到1 m/s。随着颗粒速度和料斗出口直径的增大，物料堆间产生的最大夹带气流速度增大。随着堆高、颗粒速度或料斗出口直径的增加，夹带气流速度的变化率逐渐减小。料斗出口直径对料堆间垂直轴上夹带气流的速度影响最大。料斗出口直径对涡芯高度的影响最为明显，最大高度差为33 mm。有效夹带面积随着堆高、颗粒速度或料斗出口直径的增加而增加，在2m /s时最小达到568 mm2，在30 mm时最大达到1884 mm2。

Spray dust suppression technology plays a critical role in controlling coal mine dust and has attracted growing attention in recent years. However, the diversity of research directions has made it difficult to clearly anticipate future developments in the field. To address this, the present study adopts a bibliometric approach, integrating visualization tools such as VOSviewer, CiteSpace, and Scimago with advanced deep learning models including BERTopic, Holt-Winters, Prophet, and Bi-LSTM. A comprehensive analysis was conducted on relevant publications indexed in the Web of Science Core Collection from 1994 to 2024 to identify research hotspots and forecast future trends. The findings reveal that spray dust suppression research has undergone three distinct phases: initial development, steady growth, and rapid expansion, with a marked increase in research activity after 2017. China, the United States, and Australia are the main contributors, with research concentrated in mining-focused universities and institutes. Keyword co-occurrence networks and BERTopic modeling indicate that current research centers on environmental pollution control, spray fluid dynamics simulation, the application of surfactants and charged mist, spray system optimization, and intelligent dust suppression technologies. By combining burst keyword analysis with multi-model forecasting, the study predicts that future research will emphasize the development of novel eco-friendly materials, multi-technology synergistic enhancements, and the construction of intelligent dust suppression systems. The “bibliometric analysis–topic modeling–trend prediction” methodological framework established in this study provides conceptual support for subsequent research.
