Owing to uncontrolled and uneven electrodeposition and side reactions,Zn metal anodes inevitably suffer from issues such as dendrite growth,hydrogen evolution reactions,and surface *** paper proposes an efficient strategy to address these critical issues for realizing long-life and high-capacity aqueous zinc-ion hybrid supercapacitors(ZHSCs)by incorporating low-concentration(0.05 mol·L^(-1))redox RbI electrolyte ***,rubidium cations have the ability to influence the negative Zn electrode surface via an electrostatic shielding mechanism,effectively protecting the electrode and minimizing undesired side *** an aqueous solution,iodide anions actively solvate Zn^(2+)ions by stabilizing and modulating the solvation shell surrounding Zn^(2+).Moreover,the presence of iodide ions promotes the uniform deposition of Zn^(2+)species by selective adsorption onto the electrode *** synergistic effect of the electrostatic shielding and halogen ions enables the realization of aqueous symmetric Zn||Zn cells with a substantial cycle life of more than 2000 h Additionally,when applied to commercial activated carbon(AC),the proposed strategy facilitates the development of aqueous ZHSCs,exhibiting high specific capacitances(148.8 F·g^(-1)at 4 A·g^(-1))and ultra-long cycling stability.

为定量评估余震对主震损伤结构所造成的二次损伤,该文对主余震序列型地震动的增量损伤谱进行了研究。挑选533条真实主余震序列作为输入,采用Park-Ang(1985)损伤指数定义地震损伤,通过计算结构在主震和主余震序列作用下的损伤差值,定量评价余震对结构所造成的增量损伤。研究结果表明:余震对主震损伤结构所造成的增量损伤的变异性较强。某些主余震序列会对结构造成非常显著的增量损伤,而某些主余震序列却不会对结构造成明显的增量损伤。相比于短周期结构,中长周期结构在主余震序列作用下的增量损伤更大。若主震卓越周期高于余震卓越周期,则该主余震序列可视为不利主余震序列,对结构可能造成较大增量损伤。

Hypoxia is a significant feature in most of solid tumors. Hence, developing hypoxia-responsive phototheranostic system is still a challenge. In this contribution, a supramolecular assembly strategy based on sulfonate-functionalized azocalix[4]arene(SAC4A)and cationic aggregation-induced emission photosensitizer(namely TPA-H) was proposed for hypoxia-responsive bioimaging and photodynamic therapy(PDT). Upon supramolecular complexation of TPA-H and SAC4A through electrostatic interaction,the fluorescence and reactive oxygen species(ROS) generation of TPA-H were largely inhibited. In hypoxic tumors, the azo group of SAC4A can be reduced to aniline derivative and release the included TPA-H to recover its pristine fluorescence and ROS. Interestingly, the free TPA-H undergoes cell membrane-to-mitochondria translocation during cell imaging, achieving a real-time self-reporting PDT system. In vivo tumor imaging and therapy reveal that this as-prepared supramolecular complexes have good biosafety and efficient antitumor activity under hypoxia. Such hypoxia-responsive supramolecular photosensitizer system will enrich image-guided photodynamic therapy.

Lightning-induced neutrons as a possible source of charged particles in the Earth's inner radiation belt

引用

Earth and Planetary Physics 2025年第02期 444-451页

作者： QuanQi Shi ChenYao han Qiu-gang Zong Alexander Degeling Shuo Wang SuiYan Fu PengZhi He Shandong Key Laboratory of Optical Astronomy and Solar-Terrestrial Environment School of Space Science and Technology Institute of Space Sciences Shandong University School of Earth and Space Sciences Peking University WeiHai Research Institute of Industrial Technology of Shandong University

The Van Allen radiation belts are doughnut-shaped zones surrounding Earth, filled with highly energetic charged particles whose sources or loss mechanisms have been investigated for decades. As for the inner belt, cosmic ray albedo neutron decay(CRAND),radial diffusion, and local acceleration have been considered principal sources of electrons, whereas protons are predominantly from CRAND and solar protons. In this article, lightning-induced neutrons from Earth's upper atmosphere are suggested as a possible source of protons and electrons in the inner radiation belt. These terrestrial neutrons can contribute to the inner belt population by undergoing nuclear decay. Several approaches are proposed and discussed to evaluate the potential contribution of lightning-induced neutrons to the inner belt, including magnitude estimation, Monte Carlo simulations, and in situ observations. This article discusses some avenues of further study to determine the contribution of lightning-induced neutrons to the inner radiation belt.

国防教育与基础教育课程有着天然的联系,国防教育融入基础教育课程体系是立德树人的必然要求。国防教育融入基础教育课程体系仍面临诸多问题:国防教育知识化倾向,导致本末位置颠倒;国防教育形式化倾向,导致体用关系扭曲;国防教育客体化倾向,导致纵横次序错乱。国防教育融入基础教育课程应深挖国防教育元素,实现历史与现实的跨时空交融;设立跨学科主题教育活动,实现感性与理性的跨学科通达;在活动中学习,实现认知与实践的跨领域耦合。国防教育融入基础教育课程的优化路径主要包括:跨越历史与现实,进行时空转换,构建共同言说的课程内容;整合情感与理性,倡导情智交融,实施家国在场的教学;统筹认知与实践,践行知行合一,开展行稳致远的活动。

深部地下厂房开挖过程中所产生的循环扰动会导致围岩损伤,从而降低围岩力学性质。为揭示叶巴滩水电站地下厂房中深埋花岗岩在循环扰动后的分级卸载破坏特性和损伤过程,首先进行了围压为30 MPa、循环应力分别为12.5%~17.5%(低应力)、10.0%~37.5%(中应力)、62.5%~72.5%(高应力)峰值强度的峰前恒幅循环扰动,在此基础上进行了3种分级卸围压试验,进而开展了峰前循环扰动下的深埋花岗岩特征参数演化规律分析与损伤变量构建。研究结果显示:低、中应力循环扰动对花岗岩造成的损伤可忽略不计,但高应力恒幅循环扰动会导致轻微损伤。在不同分级卸围压路径下,岩样变形主要集中在最后3个阶段的围压降低过程中,其宏观破裂模式为压剪破坏;弹性模量呈下降趋势,泊松比呈上升趋势,最大剪胀角基本相同;高轴压恒幅循环扰动后的分级卸围压试验下的岩样累积应变能最高,表现出更强的脆性破坏倾向。此外,分级卸围压下的岩样应变能均高于常规三轴压缩下的岩样应变能,后者可作为分级卸围压岩样是否进入加速损伤破裂阶段的判别阈值。采用侧向应变响应法和裂纹体积应变法确定的深埋花岗岩闭合应力、起裂应力和损伤应力分别为其峰值强度的17.9%、42.7%和73.8%,并据此建立了基于裂纹体积应变的损伤变量,进而划分了深部硬岩损伤过程的4个阶段。研究成果可为分析高应力花岗岩的破坏过程提供试验和理论支撑。
