Sc and Zn were introduced into O3-NaMn_0.5Ni_0.5O₂ (NaMN) using the combination of solution combustion and solid-state method. The effect of Sc and Zn dual-substitution on Na⁺ diffusion dynamics and structural stability of NaMN was investigated. The physicochemical characterizations suggest that the introduction of Sc and Zn broaden Na⁺ diffusion channels and weaken the Na—O bonds, thereby facilitating the diffusion of sodium ions. Simulations indicate that the Sc and Zn dual-substitution decreases the diffusion barrier of Na-ions and improves the conductivity of the material. The dual-substituted NaMn_0.5Ni_0.4Sc_0.04Zn_0.04O₂ (NaMNSZ44) cathode delivers impressive cycle stability with capacity retention of 71.2 % after 200 cycles at 1C and 54.8% after 400 cycles at 5C. Additionally, the full cell paired with hard carbon anode exhibits a remarkable long-term cycling stability, showing capacity retention of 64.1% after 250 cycles at 1C. These results demonstrate that Sc and Zn dual-substitution is an effective strategy to improve the Na⁺ diffusion dynamics and structural stability of NaMN.

采用溶液燃烧法和固态法相结合的方法在 O3-NaMn0.5Ni0.5O2 (NaMN) 中引入了 Sc 和 Zn。研究了 Sc 和 Zn 双取代对 Na+ 扩散动力学和 NaMN 结构稳定性的影响。理化性质表明，Sc 和 Zn 的引入拓宽了 Na+ 扩散通道，削弱了 Na-O 键，从而促进了钠离子的扩散。模拟结果表明，Sc 和 Zn 的双重取代降低了 Na 离子的扩散障碍，提高了材料的导电性。双取代 NaMn0.5Ni0.4Sc0.04Zn0.04O2 (NaMNSZ44) 阴极具有令人印象深刻的循环稳定性，在 1C 温度下循环 200 次后容量保持率为 71.2%，在 5C 温度下循环 400 次后容量保持率为 54.8%。此外，与硬碳阳极配对的全电池也表现出显著的长期循环稳定性，在 1C 下循环 250 次后容量保持率为 64.1%。这些结果表明，Sc 和 Zn 双替代是改善 NaMN 的 Na+ 扩散动力学和结构稳定性的有效策略。

Ti₂AlNb-based alloy was joined in a continuous drive friction welding machine under different rotational rates (500, 1000 and 1500 r/min). The microstructure and mechanical properties of the joints were investigated. It is shown that the weld zone (WZ) is fully composed of recrystallized B2 phase, and the grain size decreases with increasing rotational rate. The thermo-mechanically affected zone (TMAZ) suffers severe deformation during welding, due to which most of original precipitation phase is dissolved and streamlines are present. In the heat affected zone (HAZ), only the fine O phase is dissolved. The as-welded joint produced using 1000 r/min has the best mechanical properties, whose strength and elongation are both close to those of the base metal, while the as-welded joint obtained using 500 r/min exhibits the worst mechanical properties. Post-weld annealing treatment annihilates the deformation microstructure and fine O phase precipitates in the joints, consequently improving the mechanical properties significantly. Decomposed α₂ phase is a weakness for the mechanical performance of the joint since microcracks are apt to form in it in the tensile test.

在不同转速（500、1000 和 1500 r/min）下，用连续驱动摩擦焊接机焊接了 Ti2AlNb 基合金。对接头的微观结构和机械性能进行了研究。结果表明，焊接区（WZ）完全由再结晶的 B2 相组成，且晶粒尺寸随转速的增加而减小。热机械影响区（TMAZ）在焊接过程中发生严重变形，大部分原始析出相被溶解，并出现流线。在热影响区（HAZ），只有细小的 O 相被溶解。使用 1000 转/分钟生产的焊接接头具有最好的机械性能，其强度和伸长率都接近母材，而使用 500 转/分钟生产的焊接接头的机械性能最差。焊后退火处理消除了变形微观结构和接头中的细小 O 相析出物，从而显著改善了机械性能。分解的 α2 相是接头机械性能的一个薄弱环节，因为在拉伸试验中它很容易形成微裂纹。

To obtain high-performance Zr-based ultra-high-temperature composites, Zr-based ultra-high-temperature gradient composites were prepared by changing the laying method of the infiltrant via reactive melt infiltration. The effects of different infiltrant laying methods on the microstructure and ablative properties of Zr-based ultrahigh-temperature gradient composites were investigated. The results showed that the gradient structure of the Zr-based ultrahigh-temperature gradient composites differed when the composition ratio of the infiltrant was changed. When the thicknesses of the Zr/Mo/Si layers were 6/4/12 mm and 8/2/12 mm, the SiMoZrC solid solution content in the samples increased and decreased along the infiltration direction, respectively. The gradient samples were ablated in an oxyacetylene flame at 3000 °C for 40 s. The ablation resistance of the sample was the highest when the infiltrant was a powder and the thickness of the Zr/Mo/Si layer was 6/4/12 mm.

为了获得高性能的 Zr 基超高温复合材料，通过反应熔体渗透改变浸润剂的铺设方法制备了 Zr 基超高温梯度复合材料。研究了不同浸润剂铺设方法对 Zr 基超高温梯度复合材料微观结构和烧蚀性能的影响。结果表明，当浸润剂的成分比例改变时，锆基超高温梯度复合材料的梯度结构也不同。当 Zr/Mo/Si 层的厚度分别为 6/4/12 mm 和 8/2/12 mm 时，样品中 SiMoZrC 固溶体的含量分别沿渗透方向增加和减少。梯度样品在 3000 °C 的氧乙炔焰中烧蚀 40 秒。当浸润剂为粉末且 Zr/Mo/Si 层厚度为 6/4/12 mm 时，样品的烧蚀阻力最大。

The development of efficient nonprecious bifunctional electrocatalysts for water electrolysis is crucial to enhance the sluggish kinetics of the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). A self-supporting, multiscale porous NiFeZn/NiZn-Ni catalyst with a triple interface heterojunction on nickel foam (NF) (NiFeZn/NiZn-Ni/NF) was in-situ fabricated using an electroplating−annealing−etching strategy. The unique multi- interface engineering and three-dimensional porous scaffold significantly modify the mass transport and electron interaction, resulting in superior bifunctional electrocatalytic performance for water splitting. The NiFeZn/NiZn-Ni/NF catalyst demonstrates low overpotentials of 187 mV for HER and 320 mV for OER at a current density of 600 mA/cm², along with high durability over 150 h in alkaline solution. Furthermore, an electrolytic cell assembled with NiFeZn/NiZn-Ni/NF as both the cathode and anode achieves the current densities of 600 and 1000 mA/cm² at cell voltages of 1.796 and 1.901 V, respectively, maintaining the high stability at 50 mA/cm² for over 100 h. These findings highlight the potential of NiFeZn/NiZn-Ni/NF as a cost-effective and highly efficient bifunctional electrocatalyst for overall water splitting.

开发用于水电解的高效非贵金属双功能电催化剂对于提高氧进化反应（OER）和氢进化反应（HER）的缓慢动力学至关重要。我们采用电镀-退火-蚀刻策略，在泡沫镍（NF）上原位制备了具有三界面异质结合的自支撑多尺度多孔镍铁锌/镍锌镍催化剂（NiFeZn/NiZn-Ni/NF）。独特的多界面工程和三维多孔支架极大地改变了质量传输和电子相互作用，从而实现了卓越的双功能水分离电催化性能。NiFeZn/NiZn-Ni/NF 催化剂在 600 mA/cm² 的电流密度下，HER 和 OER 的过电位分别为 187 mV 和 320 mV，而且在碱性溶液中可持续 150 小时。此外，以 NiFeZn/NiZn-Ni/NF 为阴极和阳极组装的电解池在 1.796 V 和 1.901 V 的电池电压下分别达到了 600 mA/cm2 和 1000 mA/cm2 的电流密度，并在 50 mA/cm2 的条件下保持了 100 小时以上的高稳定性。这些发现凸显了 NiFeZn/NiZn-Ni/NF 作为一种经济高效的双功能电催化剂在整体水分离方面的潜力。

For a highly efficient recycling of a wastewater containing a high concentration of MgCl₂, Al(III) and P507 were scheduled to be removed in advance. In this study, the in-situ removal of Al(III) and P507 from a high concentration MgCl₂ solution at different pH values and Al/P molar ratios was investigated. The results showed that P507 formed organic complexes of Al_x(OH)^z+_y-P507 at pH of 2.0−4.0. At pH of 4.0−5.0, Al(III) precipitated and transferred into Al(OH)₃ with a flocculent amorphous morphology. Active sites on the Al(OH)₃ surface enhanced the removal efficiency of P507. At pH of 6.0−6.5, Al(III) and Mg(II) formed layered crystalline Al(OH)₃ and MgAl₂(OH)₈ with small pore channels and fewer active sites, resulting in a reduced removal efficiency of P507. When the Al/P molar ratio exceeded 13 and the pH was between 4.0 and 5.0, the removal rates of both Al(III) and P507 were higher than 98%, while the concentration loss of Mg(II) was only 0.2%−0.9%.

为了高效回收含有高浓度氯化镁的废水，计划提前去除 Al（III）和 P507。本研究考察了在不同 pH 值和 Al/P 摩尔比条件下原位去除高浓度氯化镁溶液中的 Al(III) 和 P507 的情况。结果表明，在 pH 值为 2.0-4.0 时，P507 与 Alx(OH)z+y-P507 形成有机络合物。在 pH 值为 4.0-5.0 时，Al(III)沉淀并转化为 Al(OH)3，呈现絮状无定形形态。Al(OH)3 表面的活性位点提高了 P507 的去除效率。当 pH 值为 6.0-6.5 时，Al(III) 和 Mg(II) 形成了层状结晶 Al(OH)3 和 MgAl2(OH)8，孔道较小，活性位点较少，导致 P507 的去除效率降低。当 Al/P 摩尔比超过 13 且 pH 值在 4.0 至 5.0 之间时，Al(III) 和 P507 的去除率均高于 98%，而 Mg(II) 的浓度损失仅为 0.2% 至 0.9%。

The damping properties were improved by preparing Al matrix composites reinforced with glass cenospheres through the pressure infiltration method. Transmission electron microscopy and scanning electron microscopy were employed to characterize the microstructure of the composites. The low-frequency damping properties were examined by using a dynamic mechanical thermal analyzer, aiming at exploring the changing trend of damping capacity with strain, temperature, and frequency. The findings demonstrated that the damping value rose as temperature and strain increased, with a maximum value of 0.15. Additionally, the damping value decreased when the frequency increased. Dislocation damping under strain and interfacial damping under temperature served as the two primary damping mechanisms. The increase in the density of dislocation strong pinning points following heat treatment reduced the damping value, which was attributed to the heat treatment enhancement of the interfacial bonding force of the composites.

The interfacial reaction behavior of Al and Ti₃AlC₂ at different pouring temperatures and its effect on the microstructure and mechanical properties of the composites were investigated. The results show that the addition of 3.0 wt.% Ti₃AlC₂ refines the average grain size of α(Al) in the composite by 50.1% compared to Al6061 alloy. Morphological analyses indicate that an in-situ Al₃Ti transition layer of ~180 nm in thickness is generated around the edge of Ti₃AlC₂ at 720 °C, forming a well-bonded Al−Al₃Ti interface. At this processing temperature, the ultimate tensile strength of Al6061−3.0 wt.%Ti₃AlC₂ composite is 199.2 MPa, an improvement of 41.5% over the Al6061 matrix. Mechanism analyses further elucidate that 720 °C is favourable for forming the nano-sized transition layer at the Ti₃AlC₂ edges. And, the thermal mismatch strengthening plays a dominant role in this state, with a strengthening contribution of about 74.8%.

研究了不同浇注温度下 Al 和 Ti3AlC2 的界面反应行为及其对复合材料微观结构和机械性能的影响。结果表明，与 Al6061 合金相比，添加 3.0 wt.% Ti3AlC2 可使复合材料中 α(Al)的平均晶粒尺寸细化 50.1%。形态学分析表明，在 720 °C 时，Ti3AlC2 边缘周围产生了厚度约为 180 nm 的原位 Al3Ti 过渡层，形成了结合良好的 Al-Al3Ti 界面。在此加工温度下，Al6061-3.0 wt.%Ti3AlC2 复合材料的极限拉伸强度为 199.2 MPa，比 Al6061 基体提高了 41.5%。机理分析进一步阐明了 720 °C 有利于在 Ti3AlC2 边缘形成纳米级过渡层。而且，热错配强化在这种状态下起着主导作用，强化贡献率约为 74.8%。

In order to enhance the mechanical properties of the selective laser-melted (SLM) high-Mg content AlSiMg1.4 alloy, the Zr element was introduced. The influence of Zr alloying on the processability, microstructure, and mechanical properties of the alloy was systematically investigated through performing microstructure analysis and tensile testing. It was demonstrated that the SLM-fabricated AlSiMg1.4−Zr alloy exhibited high process stability with a relative density of over 99.5% at various process parameters. Besides, the strong grain refinement induced by the primary Al₃Zr particle during the melt solidification process simultaneously enhanced both the strength and plasticity of the alloy. The values for the yield strength, ultimate tensile strength, and elongation of the SLM-fabricated AlSiMg1.4−Zr were (343±3) MPa, (485±4) MPa, and (10.2±0.2)%, respectively, demonstrating good strength− plasticity synergy in comparison to the AlSiMg1.4 and other Al−Si-based alloys fabricated by SLM.

To clarify the precipitation of silica hydrate from the real desilication solutions of aluminosilicate solid wastes by adding seeds and improve integrated waste utilization, the seeded precipitation was studied using synthesized sodium silicate solution containing different inorganic salt impurities. The results show that sodium chloride, sodium sulfate, sodium carbonate, or calcium chloride can change the siloxy group structure. The number of high-polymeric siloxy groups decreases with increasing sodium chloride or sodium sulfate concentration, which is detrimental to seeded precipitation. Calcium chloride favors the polymerization of silicate ions, and even the chain groups precipitate with the precipitation of high-polymeric sheet and cage-like siloxy groups. The introduced sodium cations in sodium carbonate render a more open network structure of high-polymeric siloxy groups, although the carbonate ions favor the polymerization of siloxy groups. No matter how the four impurities affect the siloxy group structure, the precipitates are always amorphous opal-A silica hydrate.

为明确铝硅酸盐固体废弃物脱硅真溶液中通过添加种子沉淀水合二氧化硅的方法，提高废弃物的综合利用水平，利用含有不同无机盐杂质的合成硅酸钠溶液对种子沉淀进行了研究。结果表明，氯化钠、硫酸钠、碳酸钠或氯化钙可改变硅氧基团结构。高聚合硅氧基团的数量随着氯化钠或硫酸钠浓度的增加而减少，这不利于种子沉淀。氯化钙有利于硅酸根离子的聚合，甚至链状基团也会随着高聚合片状和笼状硅氧基团的沉淀而沉淀。虽然碳酸根离子有利于硅氧基团的聚合，但碳酸钠中引入的钠离子会使高聚合硅氧基团形成更开放的网络结构。无论四种杂质如何影响硅氧基团结构，沉淀物始终是无定形蛋白石-A 型二氧化硅水合物。

TA1 P-Ti/AA6061 composite plate was produced by oxidizing the surface of the titanium plate and adopting a cold roll bonding process. The results revealed that the oxide film (Ti₆O) prepared on the surface of TA1 pure titanium was easy to crack during the cold roll bonding, thereby promoting the formation of an effective mechanical interlock at the interface, which can effectively reduce the minimum reduction rate of the composite plates produced by cold rolling of titanium and aluminium plates. Moreover, the composite plate subjected to oxidation treatment exhibited high shear strength, particularly at a 43% reduction rate, achieving a commendable value of 117 MPa. Based on oxidation treatment and different reduction rates, the annealed composite plates at temperatures of 400, 450, and 500 °C displayed favorable resistance to interface delamination, highlighting their remarkable strength−plasticity compatibility as evidenced by a maximum elongation of 31.845%.

TA1 P-Ti/AA6061 复合板是通过氧化钛板表面并采用冷轧粘合工艺制成的。结果表明，TA1 纯钛表面制备的氧化膜（Ti6O）在冷轧粘接过程中容易开裂，从而促进界面形成有效的机械互锁，可有效降低钛铝板冷轧复合板的最小减薄率。此外，经过氧化处理的复合板具有很高的剪切强度，尤其是在减薄率为 43% 的情况下，剪切强度达到了 117 兆帕。根据氧化处理和不同的还原率，在 400、450 和 500 °C 温度下退火的复合板显示出良好的抗界面分层能力，突出了其显著的强度-塑性兼容性，最大伸长率为 31.845%。
