This novel work presents the investigation of functionally graded lattice structures (FGLS) based on polylactic acid (PLA) and wood-reinforced PLA (WPLA) composite. The synergistic effect of a multi-material system and hybridization of two different primitive lattices (Gyroid and Schwarz primitive (SP)) on compressive strength, specific energy absorption (SEA) and stiffness was studied. The findings of the study revealed that the hybrid FGLS fabricated combining the Gyroid lattice of PLA and SP lattice of WPLA (PLA-G/WPLA-SP) exhibits the highest values of stiffness, SEA, and compressive strength.

Lithium-sulfur batteries face significant challenges due to the dissolution of lithium polysulfides (LiPSs), commonly known as the shuttle effect, which leads to a loss in charge capacity. This study uses density functional theory (DFT) calculations, with van der Waals corrections, to investigate the polysulfide anchoring potential of a boron-doped germanene monolayer (B-2DGe). The results show that the adsorption energies of LiPSs on B-2DGe range from 1.46 to 3.39 eV. Furthermore, all LiPSs on B-2DGe exhibit conductive behavior. These findings suggest that B-2DGe, as a LiPS substrate, reduces the shuttle effect and prevents polysulfide agglomeration at electrodes, improving the performance of Li-S batteries.
由于锂多硫化物（LiPSs）的溶解（通常称为穿梭效应）会导致电荷容量的损失，因此锂硫电池面临着巨大的挑战。本研究利用密度泛函理论（DFT）计算和范德华修正，研究了掺硼锗烯单层（B-2DGe）的多硫化物锚定势。结果表明，B-2DGe 上的锂多硫化物吸附能介于 1.46 至 3.39 eV 之间。此外，B-2DGe 上的所有锂离子电池都表现出导电性。这些研究结果表明，B-2DGe 作为锂离子电池基底可减少穿梭效应，防止多硫化物在电极上聚集，从而提高锂离子电池的性能。

This study investigates the tool wear and surface characteristics of TiAlN/AlCrN-coated inserts during high-speed turning of aluminium alloy and grey cast iron (GCI) in engine blocks. Cutting performance was evaluated at a constant speed of 1,130.4 m/min and a feed rate of 0.18 mm/rev over 300 shots (the number of intermittent cuts). SEM-EDX and roughness analysis revealed abrasion and adhesion as the main wear mechanisms, with a maximum flank wear of 1.14 mm, primarily due to GCI’s abrasive nature. Surface roughness measurements for aluminium HD2 and GCI were 7.09 µm and 9.15 µm, respectively. The results highlight the effectiveness of TiAlN/AlCrN coatings but show eventual breakdown under GCI, offering insights for improving tool design in bimetal machining.

Metallic coatings sprayed on ductile substrates play a crucial role in various industries by enhancing tribological properties and extending component durability, particularly in the automotive and aerospace sectors. Quasicrystalline coatings are notable for improving mechanical strength, wear resistance, and corrosion resistance. This study focuses on decagonal-symmetry quasicrystalline coatings produced from Al65Co18Cu17 powder using high-velocity oxygen fuel (HVOF) thermal spraying. The main objective was to achieve a coating predominantly composed of the decagonal-D quasicrystalline phase, as icosahedral-phase quasicrystals often decompose during thermal processing, necessitating costly additional treatments. The results showed that the coatings were mainly composed of the decagonal-D phase, with minor traces of m-Al13Co4 and B2-Al(Co,Cu) phases, eliminating the need for post-spray treatments. This advancement enhances cost-effectiveness and efficiency while maintaining the desirable properties of quasicrystals, such as high hardness and wear and corrosion resistance. The research concludes that AlCoCu (D) coatings are promising for harsh environments, offering a viable and high-performance alternative for industrial protection.

Research of Nb3Sn superconducting radio-frequency (SRF) cavities was carried out at the Institute of High Energy Physics Chinese Academy of Sciences (IHEP), in order to improve the intrinsic quality factor (Q0) and accelerating gradient (Eacc). Various recipes of coating were attempted at SRF cavities and samples made of Nb, which resulted in different Sn content. It was found that the Sn content, namely the ratio of Nb/Sn, had great influences on the performance of Nb3Sn SRF cavities. When the ratio of Nb/Sn was slightly higher than 3, the Nb3Sn SRF cavities showed the best performance during the vertical test. Q0 of 1.3 GHz 1-cell Nb3Sn SRF cavity (the ratio of Nb/Sn ≈ 3.16) reached 3.0 × 1010 (@ 4.2 K) and 1.0 × 1011 (@ 2.0 K) at low RF field. This study could provide insights on the effects of Sn content on the performance of Nb3Sn SRF cavities, which be referenced by the SRF community.

Fracture of rocks and biominerals on the microscopic scale under bending was examined. Eggs of some birds were used in the study because an eggshell is biomineral consisted of 90% of calcium carbonate of the biological genesis. Cracking in the model materials was studied in optical microscopes including in situ bending of eggshell samples. It was shown that despite brittle deformation behavior on the macroscopic scale and brittle transgranular fracture as fracture mode, the morphology of cracking of model materials looks like cracks in the neck of aluminum under tension.

Revealing the relationship between structure and optical properties of multi-peak emissive carbon dots (CDs) is important. Three types of multi-peak emission CDs were synthesized by one-step hydrothermal method with phenylenediamine (PD) isomers (o/m/p) and maleic anhydride serving as precursors. During the synthesis process, three PDs exhibited different microstructural and chemical states, resulting in various fluorescence emission centers. The multi-peak emission behavior of o-CDs and m-CDs is composed of molecular fluorophores and carbon core states, while that of p-CDs consists of surface states and carbon core states. These different fluorescence centers lead to diverse fluorescence behaviors of the CDs in different solvents and environments. This work inspires the clarification of the relationship between the structural and optical properties of multi-peak emissive CDs.

This study examines the dynamic mechanical properties of composites made via continuous filament fabrication, an additive manufacturing (AM) technique. Four Nylon/Kevlar samples with varying fiber orientations were produced, each with a 0.1 mm layer height and 3 mm total thickness, resulting in a fiber volume fraction of 15.71 % to 18.44 %. Dynamic mechanical analysis (DMA) was used to assess viscoelastic behavior, focusing on storage modulus, loss modulus, and damping factor (tan delta). The specimen F_NK1 exhibited the highest initial storage modulus, with gradual stiffness loss at higher settling temperatures (Ts), while F_NK2 showed a steeper decline, and F_NK3 and F_NK4 had lower initial moduli and greater temperature sensitivity.

The effects of melt-pool geometry on grain structure evolution in the multilayer laser metal deposition of a single-crystal superalloy are analyzed. The spatiotemporal variations in geometrical features not only affect the grain growth patterns in each layer but also lead to different overlapping behaviors and resultant substrate conditions. The initial melt pool with a large depth-to-height ratio generally contributes to sustaining the continual epitaxial growth; otherwise, a triangle-shaped columnar region with grain orientation alternatively changed can be formed.

The containing Ti-Mg-Ca-O composite particles were innovatively used to achieve microstructure refinement and properties improvement of hot-rolled seamless steel pipes, and compared with conventional steel (C# steel). The results show that the C# steel mainly consisted of parallel lath martensite after on-line quenching. Under the same rolling and heat treatment conditions, dominant Ti-Mg-Ca-O composite particles in modified steel (M# steel) were effective nucleation sites of acicular ferrite, dividing the prior austenite grains and refining microstructures. The strength values of the both steels were at the same level, however, the impact energy of M# steel was significantly higher than C# steel, increasing by 28%. This study provides an effective method for further microstructure refinement of hot-rolled seamless steel tubes.
