Highly reliable packaging interlayer materials are essential for utilizing the benefits of wide band-gap power devices. In this study, a two-dimensional mesh structure of Cu-10Ni (wt.%) alloy skeleton-reinforced SAC305 (Sn-3.0Ag-0.5Cu, wt.%) solder was employed to create solid-liquid interdiffusion (SLID) bonding connections on a Cu substrate at 250 °C and 0.03 MPa auxiliary pressure. The microstructural evolution and the mechanical property strengthening mechanisms of bonded joints with different composite solders were investigated. Due to the addition of Cu-10Ni alloy skeleton, the Cu-Ni atoms diffused into the Sn melt and acted as heterogeneous nucleation sites, contributing to the rapid nucleation and growth of (Cu,Ni)6Sn5 grains. The incorporation of Ni inhibited the merging and coarsening of intermetallic compound (IMC) grains, and the joint was composed of fine-grained (Cu,Ni)6Sn5 phase and interspersed Cu10Ni skeleton. Shear strength of the joint at soldering time 210 s reached 47.75 MPa, marking a 104.58% enhancement compared to the pristine SAC305 solder joint. The influence of grain refinement on the mechanical properties of the joint was discussed based on the Hall–Petch relationship. The grain boundary strengthening effect synergized with the toughening effect of the alloy skeleton, ultimately achieving highly reliable joints. © 2023, The Authors. All rights reserved.

The precise manipulation of thermal radiation in adaptive infrared thermal camouflage has emerged as a notable challenge, attracting widespread attention in both commercial and military applications. Here, we report a high-performance, dual-responsive device based on a VO2/SiO2/ITO multilayer structure for thermal camouflage. This device exhibits a maximum modulation capability of 0.61 in thermal emissivity, with robust stability over 3000 cycles. Theoretical simulations reveal that its exceptional infrared emissivity regulation originates from the Fabry-Pérot resonance within the VO2/SiO2/ITO configuration. Battery thermal-camouflage experiments validate the device's exceptional thermal camouflage performance with significant reduction in infrared temperature variation, outperforming traditional and passive VO2based systems. This dual-responsive design demonstrates promising potential in artificial infrared camouflage, thermal cloaking, and advanced thermo-optical systems. © 2025, The Authors. All rights reserved.

Effect of stress loading direction on microstructure evolution and age-hardening behavior of a stress-aged Mg-7Sn alloy

The effect of stress loading direction on microstructure evolution and age-hardening behavior of a stress-aged Mg-7Sn alloy with a compressed stress of 40 MPa at 160 °C was investigated in this paper. The compressive stress perpendicular to the c-axis effectively facilitated the formation of a high volume fraction of twins and Mg2Sn phases, thereby promoting a c-axis//ED texture. In contrast, the stress parallel to the c-axis resulted in the formation of small amounts of twins and Mg2Sn phases, which further reinforced the basal plane texture. The stress aging with compressive stress applied perpendicular to the c-axis significantly increased the peak hardness of the alloy and reduced the time reached the peak hardness, compared to compressive stress applied parallel to the c-axis. The compressive testing results indicated that the stress peak-aged alloy perpendicular to the c-axis exhibited excellent mechanical properties, whose compressive yield strength, ultimate compressive strength and compressive elongation were 191.3 MPa, 449.9 MPa and 12.6 %, respectively. The high compressive strengths of the peak-aged alloy at a compressive stress perpendicular to the c-axis was mainly attributed to the grain refinement and precipitation strengthening of Mg2Sn phase. © 2025 Elsevier B.V.

作者： Yu, Yongkun Gong, Minjian Dong, Chenxu Xu, Xu State Key Laboratory of Advanced Technology for Materials Synthesis and Processing International School of Materials Science and Engineering Wuhan University of Technology Hubei Wuhan 430070 China

Extensive efforts have been dedicated to improving the physical and (electro)chemical properties of solid electrolytes in pursuit of promising all-solid-state batteries (ASSBs). Nevertheless, increasing studies has demonstrated the critical impact of interface issues on battery performance. Hence, the primary focus of this review is on the utilization of thin-film deposition techniques (TFDTs) in surface and interface engineering of ASSBs. First, we explain the issues associated with solid-solid interfaces. Second, the working mechanism and advantages/disadvantages of TFDTs are briefly introduced. Third, we summarize the existing studies and highlight notable progress in the anode and cathode interfaces of ASSBs. The interface of all-solid-state thin-film batteries (ATFBs) is also discussed. Lastly, we conclude the relevant scientific problems of TFDTs application in ASSBs interface engineering, and provide future directions and prospects. © 2023 The Authors

Zero-Valent Iron Supported by Dendritic Mesoporous Silica Nanoparticles to Purify Dye Wastewater

The presence of different types of organic dyes in water stream will clearly give rise to unexceptional side effects on living organisms. Emerging physical or chemical methods have been developed for the treatment of dye-involving water, but the exploration for adequate design strategy and technique available is still ongoing. Here, the zero-valent iron (ZVI) was prepared by a liquid phase sodium borohydride reduction approach and then integrated with dendritic mesoporous silica nanoparticle (DMSN) to construct the Janus magnetic adsorbent (denoted as ZVI-DMSN), which could be employed to purify dye wastewater. The structure, magnetic properties and dye adsorption results of ZVI-DMSN were systematically investigated. The ZVI component can enable efficient solid-liquid separation through magnetic separation route, and, more importantly, provided additional binding sites for adsorption process to increase the adsorption capacity. The thermodynamic analysis of adsorption indicated that the adsorption of typical organic dyes was an irreversible, spontaneous and endothermic process. Moreover, ZVI-DMSN adsorbent was recyclable, showing a regeneration efficiency of more than 80% after 5 cycles. We believe that ZVI-DMSN, as an inexpensive adsorbent material with excellent adsorption properties, e.g., short time, high efficiency and large capacity, will host vast potential for removal of dyes in water bodies. © 2023, The Authors.

Understanding the Environmentally Driven Corrosion Behavior and Mechanism of Aln/Mo Functionally Graded materials Exposed to Li/Lif-Licl-Libr Vapor

SSRN

引用

SSRN 2022年

作者： Jia, Mingyong Chen, Fei He, Yaling Wu, Yueqi Shen, Qiang State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan430070 China State Key Laboratory of Advanced Electromagnetic Engineering and Technology Huazhong University of Science and Technology Wuhan430074 China

The environment temperature-driven corrosion behavior and mechanism of Li/LiF-LiCl-LiBr vapor on AlN/Mo functionally graded materials were investigated. It is shown that the corrosion failure of AlN/Mo FGMs driven by Li vapor begins at 650 ℃. Li vapor not only diffuses along the grain boundaries of AlN but also enters the interior of the adjacent AlN grains, leading to the disintegration of the AlN matrix. The 3D framework of Mo is hardly affected in Li/LiF-LiCl-LiBr vapor, preventing the cracking caused by inconsistent deformation inside the AlN/Mo sealing component. This work provides a reference for the operating temperature of liquid metal batteries. © 2022, The Authors. All rights reserved.
