In this study, a combined experimental, numerical and theoretical investigation is conducted on the penetration of semi-infinite 4340 steel targets by a homogeneous 93 W rod and two types of jacketed rods with striking velocities of 0.9-3.3 km/s. The results show that the jacketed rods produced typical“co-erosion” damage at all test velocities, except for the 93 W/1060 Al jacketed rod, which switched from an early “bi-erosion” damage to later “co-erosion” damage at a striking velocity of 936 m/s. However, the homogeneous 93 W rod always forms a large mushroom head during the penetration process. The damage mechanisms of these two types of jacketed rods differ for striking velocities of 0.9-2.0 km/s, but this difference gradually decreases with increased striking velocity. For velocities of 2.0-3.3 km/s, all three types of projectiles exhibit typical hydrodynamic penetration characteristics, and the damage mechanisms of the two types of jacketed rods are almost identical. For the same initial kinetic energy, the penetration performance of the jacketed rods is distinctly superior to that of the homogeneous 93 W *** with jacket density, jacket strength shows a more significant influence on the damage mechanism and penetration performance of the jacketed rod. Finally, an existing theoretical prediction model of the penetration depth of jacketed rods on semi-infinite targets in the co-erosion mode is modified. It transpires that-in terms of penetration depth-the modified theoretical model is in good agreement with the experimental and numerical observations for 93 W/TC4 and 93 W/1060 Al jacketed rods penetrating semi-infinite 4340 steel targets.

Heavy ion-induced single event upset sensitivity evaluation of 3D integrated static random access memory

Nuclear Science and Techniques 2018年第3期29卷 31-41页

Heavy ion-induced single event upsets(SEUs)of static random access memory(SRAM), integrated with three-dimensional integrated circuit technology, are evaluated using a Monte Carlo simulation method based on the Geant4 simulation toolkit. The SEU cross sections and multiple cell upset(MCU) susceptibility of 3D SRAM are explored using different types and energies of heavy *** the simulations, the sensitivities of different dies of 3D SRAM show noticeable discrepancies for low linear energy transfers(LETs). The average percentage of MCUs of 3D SRAM increases from 17.2 to 32.95%, followed by the energy of ^(209)Bi decreasing from 71.77 to 38.28 MeV/u. For a specific LET, the percentage of MCUs presents a notable difference between the face-to-face and back-toface structures. In the back-to-face structure, the percentage of MCUs increases with a deeper die, compared with the face-to-face structure. The simulation method and process are verified by comparing the SEU cross sections of planar SRAM with experimental data. The upset cross sections of the planar process and 3D integrated SRAM are analyzed. The results demonstrate that the 3D SRAM sensitivity is not greater than that of the planar SRAM. The 3D process technology has the potential to be applied to the aerospace and military fields.

为加深对爆炸复合界面微观性能的理解,采用自主研发的爆炸焊接技术制备钽箔/钢板复合试样,通过不同的表征方法对其界面显微组织和力学性能进行研究。结果表明,钽/钢界面呈现波长和波幅分布均匀的波形结构。熔化区主要位于涡旋内部,只有少量分布在结合界面处,其形成原因是由于两种金属强烈的机械混合。电子背散射实验揭示了钽/钢界面存在多样性的晶体结构,在钽中形成高度弯曲和细长晶粒,而钢中形成细小的等轴晶和柱状晶粒。在钢中发现了多条由小等轴晶组成的绝热剪切带,这是由于应力波集中在狭窄的路径中,导致该区域内的材料发生再结晶过程。纳米压痕结果揭示了结合区域不均匀的力学性能,很好地证明了碰撞诱导的显微组织和化学成分变化。

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

Journal of Energy Chemistry 2025年第1期100卷 770-778页

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
