In this study, Computational Fluid Dynamics–Discrete Element Method (CFD − DEM) was employed to establish a polydisperse particle system model containing 0.5 mm fine particles and 2.0 mm coarse particles. The particle flow characteristics, dynamic behavior, and wear mechanisms inside the pump were systematically investigated under five different mixing ratios. The reliability of the numerical simulation was verified through high-speed photography experiments and elbow erosion experiments. Particle trajectory analysis reveals distinct dynamic behaviors: coarse particles follow complex paths with long residence times, while fine particles demonstrate strong fluid-following ability but tend to recirculate near the volute tongue. Collision frequency and energy dissipation analysis indicate that coarse particles dominate the dissipation process, with the shear work on the volute surface exceeding that of other components by about one order of magnitude. The wear severity of the components ranks as volute > blades > hub > shroud, and the wear regions show clear spatial migration as the proportion of coarse particles increases. When the coarse particle fraction increases to 2:1, the buffering effect of the particle layer slows the wear rate. The particle size effects and wear mechanisms revealed in this study provide important insights for advancing powder transport technology.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"37 2","pages":"Article 105163"},"PeriodicalIF":4.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145922472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key challenge in advancing this system is the development of active electrode material that combine strong photoactivity and highly reversible capacity. Herein, the hierarchical CuS nanoflower (H-CuS-NF) with reversible copper-ion storage and photo-responsive properties is demonstrated as a promising photo-cathode material for aqueous copper ion battery. Compared to the dark condition as well as CuS nanosheet (CuS-NS), the H-CuS-NF cathode delivers a higher discharge capacity of 662.0 mAh/g at 600 mA/g and a superior rate retention of 87.6 % when the current density increases from 600 to 1800 mA/g under illuminated condition. The enhanced performance is attributed to a more robust photo-assisted charge–discharge process, as confirmed by electronic structure analysis and theoretical simulations, which effectively facilitates the CuS-Cu<sub>2</sub>S conversion. Furthermore, the photo-assisted H-CuS-NF//Zn hybrid battery exhibits an expanded operating voltage of 1.15 V, exceptional discharge capacity of 694.6 mAh/g, and photo-charging capability of 104.2 mAh/g (after lighting 4 h), showing its significant potential for commercial applications.

Electrostatic adsorption can cause the sliding speed of particles to slow down or even lead to blockage. This study enhances the point charge model by accounting for polarization-induced electrostatic effects, improving the accuracy of discrete element simulations for the electrostatic force of cluster particles. The multiple relationships between the polarization effect model and the point charge model are examined under varying relative permittivity, surface charge densities, and particle sizes. The polarization effect model yields a stronger electrostatic attractive force. The inclination angle calculated using the polarization effect model has an error of only 4.9% compared with the inclination angle experimental results, which is smaller than 24.4% of the point charge model. Furthermore, the polarization effect model successfully simulates the adsorption of charged particles onto uncharged particles and onto small like charged particles. Discrete element simulation results indicate that, during sliding, the polarization effect model results in greater electrostatic adsorption of particles onto the metal chute. This helps guide the process conditions through discrete element simulation to prevent the occurrence of blockage caused by the electrostatic adsorption of particles.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"37 2","pages":"Article 105187"},"PeriodicalIF":4.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146170349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, processability of copper alloys remain challenging due to the high laser reflectivity and thermal conductivity. The aim of this work is to develop a cost-effective process for producing near defect-free parts from CuCrZr alloy via the laser powder directed energy deposition (LP-DED) technique. For this purpose, a thermal coating procedure was established and implemented in order to increase the laser absorptivity of this alloy by forming an absorptive layer around the powder particles, as well as increasing their surface roughness. The results showed that the combination of oxidation and nitriding procedures formed a stable and thick layer around the powder particles that can effectively improve the processability of this copper alloy and increase the density of the bulk specimens by increasing the melt pool stability. The optimized process parameters successfully resulted in near-fully dense bulk parts without using excessive input heat that could have damaged the optics and nozzle.

The TiO<sub>2</sub>@In<sub>2</sub>S<sub>3</sub>/MIL-101(Cr) composite exhibited outstanding photocatalytic and adsorptive properties, achieving complete removal of PSMPs (500 mg L<sup>−</sup>1) within 90 min and 97% removal of TC (30 mg L<sup>−</sup>1) within 210 min under visible-light irradiation. In a binary pollutant system, the composite enabled full elimination of both PSMPs and TC within 240 min, with PSMPs reaching 100% removal at 180 min and TC at 240 min. The superior performance was attributed to enhanced charge carrier separation and the suppression of electron–hole recombination, facilitated by the engineered heterojunction structure. Reusability tests confirmed the material’s stability, with over 94% removal efficiency retained after four consecutive cycles. Moreover, adsorption experiments revealed a pronounced pH dependence, with optimal removal efficiency observed at pH 5.
