Here, the effects of Ru and ball-milling on the mechanical properties of WC–10Co-cemented carbide were investigated using systematic characterisation and microstructure analysis. It was found that with an increase in the Ru content, the WC grain morphology and grain size did not change; however, the values of density and coercivity, Co magnetism, hardness, and fracture toughness of cemented carbide were changed. When the Ru content was 4%, compared with the alloy without Ru, the toughness increased from 16.8 to 24.2 (MPa. m1/2) and the hardness increased from 1290 to 1330 (HV30). Meanwhile, the analysis of the mixing process shows that the optimal ball-milling time is determined by the performance combination of the obtained alloy.

To improve the electrochemical performance of CF x for lithium primary batteries , a ball milling treatment of CF x and urea with various mass ratios is carried out in this paper. It is shows that the weight ratio of urea/CF x significantly affects the electrochemical performance of the ball-milled CF x . Electrochemical tests show that the modified CF x material exhibits excellent electrochemical performance with much enhanced rate capacity, improved discharge platform, and lowered initial potential delay compared with the untreated CF x . In detail, when the weight ratio of urea/CF x is 5, the material delivers a discharge capacity of 550.6 mAh g −1 with a high power density of 10309 W kg −1 (at 5000 mA g −1 and 25 °C) and exhibits an excellent electrochemical stability at low temperature of 5 °C (power density up to 5922.5 W kg −1 at 3000 mA g −1 ). The outstanding electrochemical performance is mainly due to the synergistic effect of enlarged interlayer distance , decreased particle size, and increased surface area, which resulting in improved the electrochemical reaction activity, decreased reaction resistance, and facilitated lithium ions diffusion.

Two-dimensional MXenes (such as Ti 2 C, V 2 C, Nb 2 C, Ti 3 C 2 , and Nb 4 C 3 ) have shown enormous potential in lithium ion storage, and the exploration of new and/or high- performance MXene-based lithium ion storage materials is an active field. This present work demonstrates the synthesis of two-dimensional vanadium carbide V 4 C 3 MXene by selectively etching Al layers from V 4 AlC 3 in hydrofluoric acid at 55 °C. Large specific surface (∼52.1 m 2 g −1 ) and interlayer spacing (∼0.466 nm) can be obtained in V 4 C 3 MXene via adding sufficient ball-milling treatment on precursor V 4 AlC 3 , which is benefit for lithium ion storage. As an anode material for lithium ion batteries, it shows high capacity as well as good rate capability and cycling performance. More specifically, V 4 C 3 delivers a high specific capacity of 225 mAh g −1 after 300 charge/discharge cycles at a current density of 0.1 A g −1 , and 125 mAh g −1 at 1 A g −1 . This work provides another potential MXene-based lithium ion storage material and is expected to inspire more explorations of high-performance MXene-based electrode materials for lithium ion batteries and capacitors.

Ball milling was used on synthesized Cr 2 AlC powders, and dense Cr 2 AlC bulk ceramics with almost pure phase were fabricated by hot pressing these ball milled Cr 2 AlC powders at 1300 °C for 2 h under 30 MPa. The phase compositions and the microstructures of powders and bulk ceramics were characterized. The mechanical properties and dislocation analysis of bulk ceramics were also investigated. Our results indicated that the grain size of powders became uniform and smaller after ball milling, which was also inherited in the bulk ceramics. Moreover, the mechanical properties of hot pressed Cr 2 AlC ceramics, including flexural strength , fracture toughness, and Vickers hardness , significantly increased by using ball milled powders treated at speed 200 rpm. The organization of hexagonal dislocation networks during hot pressing and reduction of grain size both had a positive effect on improving mechanical properties.

Herein, a 413-type high-entropy (Mo 0.2 Cr 0.2 Nb 0.2 Ti 0.2 V 0.2 ) 4 AlC 3 MAX phase was successfully prepared. To elucidate the influence of high-energy ball milling on microwave absorption performance, the microstructural evolution and electromagnetic characteristics of materials subjected to varying milling durations were comprehensively investigated. Via the ball-milling process, multiple reflections, polarization loss and conductive loss are largely improved due to particle size refinement, formation of thin flakes and increased shape anisotropy. Comparative analysis revealed substantial performance enhancement in samples milled for 1 h (M1) and 3 h (M3). The unmilled powders (M0) demonstrated a minimum reflection loss (RL min ) of -23.1 dB at 4.5 mm thickness and an effective absorption bandwidth (EAB) of 2.6 GHz at 5.0 mm. In contrast, M1 achieved a RL min low to -51.8 dB at 2.3 mm, while M3 exhibited an optimal EAB of 4.1 GHz at 1.06 mm. However, extending the milling duration to 6 h resulted in diminished absorption performance compared to M1 and M3, primarily due to compromised impedance matching characteristics. Therefore, via a proper ball-milling process, microwave absorption performance of high-entropy MAX phase powders can be remarkably boosted, providing a straightforward and effective approach for performance optimization in electromagnetic wave absorption applications.

Ball milling treatment could affect the microstructures, improve the emulsification properties of curdlan (CL) and regulate the emulsion gel properties of CL based emulsion gel in two-ways. With increasing ball milling time (1 h–8 h), the particle size first decreased and then increased, the relative crystallinity decreased, and the contact angle increased. Ball milled curdlan (BMCL)-6 h showed the best emulsifying property and stability, which was the combined effects of decreased particle size and increased hydrophobic property. Ball milling 1 h and 2 h significantly improved the hardness and chewiness of CL-based emulsion gels, while, ball milling 4 h–8 h could make the emulsion gels much softer and ice cream-like. When the emulsion gels were heated twice consecutively, the visual appearance and texture properties did not change significantly, indicating the excellent thermal stability of these emulsion gels. The BMCL based emulsion gel with adjustable gel properties and good thermal stability has a wide range of uses in the food system.

Barium titanate was successfully synthesized through both the solid-state method and the oxalate thermal decomposition method. The differences in tetragonality and particle size between the two methods were discussed using X-ray diffraction, scanning electron microscopy, and the laser diffraction method. The elemental content of the impurities ws characterized by an inductively coupled plasma optical emission spectrometer. Meanwhile, the influence of process parameters such as sintering temperature, aging time, and ball milling treatment on the morphology and size of powders was investigated. The results revealed that the oxalate thermal decomposition method could fabricate the BaTiO 3 with a narrow particle size distribution and high tetragonality. Additionally, ball milling treatment offered a significant advantage in reducing particle agglomeration caused by high sintering temperatures and in producing homogeneous BaTiO 3 , which was suitable for industrial production.

Due to the innate recalcitrancy caused by robust hydrogen bonding interaction, cellulose cannot be easily processed into high-valued materials or chemicals. Herein, a solvent-free ball milling treatment was conducted to activate microcrystalline cellulose (MCC). The research results demonstrated that ball milling treatment rapidly reduced the average particle size (Ð) and crystalline index (CrI) of MCC. Ball milling treatment for 1 h resulted in the Ð and CrI of MCC decreasing from 48 μm and 84.5 % to 23.3 μm and 25.4 %, respectively. Further prolonging the ball milling time from 1 h to 4 h slightly reduced the Ð and CrI of cellulose but led to the degradation of cellulose. Furthermore, the ball milling-activated cellulose (BMC) was chemically modified for preparing polylactic acid (PLA)/modified cellulose (m-BMC) composite films. Benefitting from the decreased Ð and valid surface modification of BMC, the tensile strength and elongation at break of the achieved PLA/m-BMC improved by 77.2 % and 189.3 % compared with the PLA/MCC, respectively. Besides, ball milling for 1 h improved the relative contents of saccharides in the pyrolysis products of cellulose from 33.2 % to 60.4 %. This work provided some basic understanding of ball milling activation of cellulose for further efficient surface modification and pyrolysis.

Biochars from Chinese medicine material residues and furfural residues at 300–600 °C (MBC300–MBC600 and FBC300–FBC600) were used as adsorbents for removing tetracycline (TC) from water. The influence of pH and co-existing of cations or low molecular weight organic acids (LMWOAs) was investigated on TC adsorption. Further, the bulk biochars were treated by ball milling into sub-micron particles, and their properties and adsorption performance toward TC were also characterized. For pristine biochars, TC adsorption was nonlinear and heterogeneous. Heterogeneity of biochars resulted in multiple sorption mechanisms, including H-bonding, π-π interaction, and pore filling. FBC300 and FBC600 had maximum sorption at pH 5–7. Electrostatic repulsion of positively charged biochar surfaces with TCH 3 + at pH < 3 or negatively charged biochar surfaces with TCH − and/or TC 2− at pH > 7 was not favorable for TC removal. TC sorption decreased with increasing Na + concentrations from 0 to 0.1 mol/L, and bivalent cations (Ca 2+ and Mg 2+ ) showed greater inhibiting effect relative to monovalent ones (Na + and K + ). The LMWOAs could combine with co-existing cations, thus reducing the inhibitory effect of cations and improving TC sorption. The ball milling caused remarkable size reduction of biochar particles, thus exposing more active surfaces to capture more TC molecules from water. This study provided low-cost and high-efficiency biochar absorbents to remove antibiotics from water and will benefit for understanding the relationship between TC sorption characteristics/mechanisms and biochar properties.

The dissolution and homogeneous processing of lignocellulosic biomass presents a significant challenge for advanced biorefineries. In this work, we firstly investigated the dissolution behavior of corn stover-based lignocellulose in 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU)/CO 2 /DMSO solvent system. The dissolution proportion reached 74.3 % via a two-step procedure, which involved pretreating of corn stover in DBU/DMSO solvent at 140 °C for 4 h, followed by dissolution at 50 °C for 6 h under 5 MPa CO 2 . Furthermore, the solubility of the corn stover can be improved by ball-milling treatment. Rheological behavior revealed that the solution viscosity and the intermolecular interactions decreased following ball-milling treatment. Subsequently, a small amount of wood pulp cellulose was incorporated to produce mechanically robust, fully UV-shielding, and all-biomass composite films. The tensile strength of the composite film containing 50 wt% wood pulp cellulose reached 47 MPa. This study provides significant insights into the development of green dissolution systems for lignocellulose and the development of lignocellulose-based advanced materials.

This work is focused on the modification of insoluble dietary fiber from pomelo ( Citrus grandis ) peel (PP-IDF) by ball milling. Ball milling intensified water and oil holding capacity and water swelling capacity by 43.7%, 65.1%, and 107.5%, respectively. Besides, 97.1% of taurocholic acid, 45.3% of glucose, and 9.3 μg/mg of NO 2 − were bound by milled insoluble dietary fibers (IDFs). The oil-in-water Pickering emulsions were successfully emulsified by ball-milled PP-IDFs. The ball-milled PP-IDF for 2.0 hr (PP-IDF-BM2h) exhibited higher stability after storage owing to its relative strong electrostatic and steric repulsions intensified by milling process. A simulated three-stage gastrointestinal tract (GIT) model was employed to explore the physical stability of emulsion in the digestive system. Ball milling contributed promotion on stability emulsion but ion strength in simulated liquids predominated in affecting ζ potential. Overall, ball milling extended green protocols for modification of properties for dietary fiber, providing a promising application in food industry. Practical applications For safety consideration, materials used for food processing should be in low toxicity with less employment of chemicals. Hence, it is essential to develop a green and renewable strategy to modify properties of dietary fiber (DF) in food applications. Ball milling is a simple and low cost strategy that can effectively improve or modify physicochemical properties including crystallinity, surface potential, water and oil holding capacities, and hydrophilic and hydrophobic properties. Importantly, ball milling can treat dietary fiber in batch processing with no waste and chemicals, which is suitable for industrial applications.

Ternary Cu 3 SbSe 4 thermoelectric material with a diamond-like structure exhibits good thermoelectric performance in the middle-temperature region. In this study, Cu 2.98 Co 0.02 SbSe 4 material with intrinsically low thermal conductivity was prepared by a melting–ball milling–hot pressing process. The maximum zT value for the Cu 2.98 Co 0.02 SbSe 4 sample was 0.7 at 650 K, which was about 190% higher than that of the pristine sample. The improvement in thermoelectric performance was ascribed to the realization of multi-scale features induced by ball milling. It was found that multiple scattering centers of phonons were formed via interfacial engineering, including dislocations, nano-holes and grain boundaries, which offers an applicable pathway for the reduction of lattice thermal conductivity.
