Considering the rapidly growing research enthusiasm on this topic over the past several years, here the recent progress of WS_(2)/WSe_(2)@graphene nanocomposites in electrochemical energy storage applications is summarized. Furthermore, various methods for the synthesis of WS_(2)/WSe_(2)@graphene nanocomposites are reported and the relationships among these methods, nano/microstructures, and electrochemical performance are systematically summarized and discussed.

基于应力发光的应力传感技术因其独特的机械-光子转换性质在柔性电子、结构健康诊断、生物力学工程和自供电显示等领域显示出巨大的潜力.然而,应力发光传感技术面临的一大挑战是当施加的机械载荷超过其强度极限时,具有典型无机@有机结构的应力发光传感材料将被损坏,从而降低其传感系统的可靠性和耐久性.本文提出了一种自修复方法,即通过构建聚硼硅氧烷/聚二甲基硅氧烷(PBS/PDMS)双网络结构来解决传感材料的失效问题.PBS网络中的动态硼酸酯键提供自愈合能力,化学交联的PDMS网络使应力发光材料保持良好的弹性和结构稳定性.这种双网络结构材料的力学性能和应力发光性能即使在遭受致命的断裂后也能得到有效恢复,室温下修复10分钟后拉伸强度恢复率为75%,机械-光子转换效率恢复率近100%.这种自修复的应力发光材料可以极大地促进应力发光技术在复杂、高强度和柔性应力传感中的应用.

Designing electrocatalysts with superior performance is widely recognized as one of the main strategies to address the practical challenges faced by Li-O2 batteries. Elemental doping and vacancy engineering can alter the local electronic structure, thereby influencing the adsorption and catalytic activity of reaction products. This manipulation is critical for improving the overall performance of Li-O2 batteries. Nickel-doped cobalt phosphide with abundant phosphorus-vacancy were synthesized as electrocatalysts to enhance the electrochemical efficiency of Li-O2 batteries by increasing phosphorus vacancies. The resulting nanocomposites as the electrocatalysis in the non-aqueous Li-O2 batteries exhibited outstanding electrochemical performance, including low overpotential and impressive cycling stability up to 741 cycles at a current density of 500 mA g-1. What is more, with quasi-solid-state electrolytes, the assembled Li-O2 batteries still can work up to 91 cycles. This study demonstrates that the appropriate element doping and vacancy construction of transition-metal-phosphides could be a favorable approach to develop Li-O2 batteries. © 2024, The Authors.

Research on the cross-scale mapping mechanism of friction mechanical behavior of metal rubber based on topological interference: Material level friction strengthening phenomenon

Based on the digital forming method of metal rubber, the Global point topology model (GPTM) reflecting the spatial characteristics is established to realize the mapping relationship between the index hardening characteristics of metal rubber and the wire turn motion behavior under the macro scale. The research shows that, with the reduction of the allowable wire turn motion space and the increase of the wire turn surface roughness, the internal multi-regional wire turns successively appear the spatial motion interference phenomenon, that is, the generation of the hard friction region, which is often the main cause of the metal rubber index hardening characteristics. At the same time, two kinds of materials, SUS-304 and Nichrome, are introduced to establish a microscopic model of metal surface roughness with fractal characteristics, aiming at realizing the research on the cross-scale friction mechanical behavior of metal rubber from the material level (microscopic level). The results show that HCP increases 97.6 % and 13.9 % respectively when the material is plastically deformed. While increasing the hardness and strength, the extrusion friction at the contact interface is increased, which affects the friction mechanical properties of metal rubber. The metal rubber (ASS-MR) made of 304 stainless steel entered the plastic phase earlier than that made of Cr20Ni80 (NI-MR) and increased the strength by phase change and rapidly entered the index hardening. The difference of mechanical behavior in the soft phase is closely related to the change of HCP on the contact surface of wire turn in the sliding process. Through the bottom-up trans-scale analysis method, the multi-level mapping relationship of metal rubber from the bottom material to the space structure and then to the nonlinear mechanical behavior is realized, which provides a new idea for exploring the basic performance and mechanism of this kind of micro-pore topology materials.
