Summary: The study investigated the effect of ball-milling on the absorption behaviors of flaky carbonyl iron powders (F-CIPs) and found that ball-milled F-CIPs exhibited better absorption ability than raw spherical CIPs. The sample milled at 200 r/min for 12 h and the sample milled at 300 r/min for 8 h showed remarkable electromagnetic parameters, with a minimum reflection loss peak of -14.04 dB and a maximum bandwidth of 8.43 GHz. These findings support the potential of ball-milled flaky CIPs for microwave absorption.

Summary: This study investigated the influence of La2O3-Y2O3 co-doped ZrO2 on its phase transformation behavior, phase stability, and microstructure. It was found that replacing part of Y2O3 with La2O3 increases the tetragonal and cubic phase of zirconia powder, enhancing the fracture strength of the subsequent synthesized materials. Additionally, the stability of zirconia stabilized with La2O3 doping is significantly improved compared to that of Y2O3 alone. The optimal doping amount was found to be 2.8Y0.2La, which exhibited the best phase composition, stability, particle size distribution, and dispersion degree.

Summary: This work investigates the impact of varying milling times on the structural and mechanical properties of Ti-Nb-Mo alloy. The study found that the quantity of beta-Ti phase increased with the milling time. The structural evolution and morphological changes of the milled alloys depended on the duration of milling. As the milling time increased, the grain size decreased, resulting in an increase in density, microhardness, and elastic modulus. The Ti-25Nb-25Mo alloy exhibited good anti-wear ability and higher resistance to plastic deformation.

Summary: Efforts to generate organomanganese reagents under ball-milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. This unique reactivity can also be translated to solution, but pre-milling of the manganese is required for this transformation.

Summary: A rapid and high-yield method based on a microfluidization technique is developed to obtain exfoliated BNNS with a record high aspect ratio of approximate to 1500 and low degree of defects. The composite film made of BNNS and poly(vinyl alcohol) (PVA) matrix exhibits an in-plane thermal conductivity of 67.6 W m(-1) K-1 at a BNNS loading of 83 wt %, leading to a record high value of thermal conductivity enhancement (approximate to 35,500). This provides a practical route to produce electrically insulating polymer composites with high thermal conductivity for thermal management applications in modern electronic devices.

Summary: In this work, microstructure observation and thermo-mechanical property characterization of ion-irradiated Zr-0.5Sn-0.5Nb-0.3Fe-0.015Si alloys were investigated. Experimental results showed that the addition of solute elements facilitated the formation of second phase particles and their transformation from crystalline to amorphous state during irradiation. The actual irradiation depth exceeded the predicted value. The influence of irradiation-induced defects on the macroscopic mechanical behaviors of Zr alloys was studied through nano-indentation tests.

Summary: A green and efficient method was proposed to prepare stable aqueous dispersions of carbon nanotubes. Functionalized carbon nanotubes (CNTs@CMC-Na) were prepared using a microwave-assisted ball milling apparatus. The resulting CNTs@CMC-Na exhibited excellent dispersibility and increased the thermal conductivity of pure water. Tribological tests showed that CNTs@CMC-Na had protective, mending, and cooling effects at the friction interface, reducing friction coefficient, wear width, and temperature of the interface.

Summary: In this study, the effects of different isothermal annealing temperatures on the microstructure and uniaxial compression properties of Cu45Zr45Ag7Al3 amorphous alloy were investigated. It was found that different phases precipitated successively from the amorphous alloy matrix with the increase of annealing temperature, resulting in changes in fracture strength and plastic strain. The presence of a nanocrystalline Cu10Zr7 phase at an annealing temperature of 741 K improved the fracture strength, while higher temperatures led to decreased strength and increased plasticity.

Summary: A 3D + 1D model was used to study the impact of liquid water in cathode channels on oxygen transportation. The presence of liquid water was found to hinder the transport of oxygen towards catalyst layers. Factors such as droplet numbers, volumes, contact angles, and liquid regimes influenced the water coverage, which in turn affected oxygen transportation. The study also revealed varying decreases in current densities depending on droplet characteristics and increases in current densities for the film regime with specific water volumes.

Summary: In this article, Cu45Zr45Ag7Al3 amorphous alloys were prepared using the copper mold suction casting method, and its three-point-bending fatigue performance was studied. The structural characteristics of the alloy were analyzed using X-ray diffraction (XRD), and the fatigue fracture morphology was analyzed using scanning electron microscopy (SEM). The results showed that the three-point-bending fatigue fracture surface morphology mainly consisted of three regions: the fatigue crack initiation region, the steady-state crack propagation region with typical fatigue stripes, and the final rapidly fracture region. The fatigue crack source was micropores ranging in size from 30 to 50 μm, where numerous shear bands formed. The fatigue limit of amorphous alloys was 410MPa, which was higher than the four-point-bending fatigue limit.

Summary: Phosphorus is a potential anode material for potassium-ion batteries due to its high specific capacity and low operation plateau. However, the actual reversible capacities of phosphorus-based anodes are much lower than the theoretical capacity. In this study, high-resolution solid-state 31P NMR, XRD measurements, and density functional theory calculations were performed to understand the (de)potassiation reaction mechanism of phosphorus anodes. The results revealed an asymmetrical nanocrystalline-to-amorphous transition process, as well as the existence of various complicated K-P alloy species, which contribute to the lower capacity of phosphorus-based anodes.
