Rare Metals, EarlyView.ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

Measures of underwater cultural heritage protection in Zhangzhou [PDF]
, 2015 目前中国水下文化遗产因盗捞行为和水域环境恶化而面临严重的困境。为了解决该难题，国家文物局启动了漳州水下文化遗产安全监控项目。项目的开展，使得水下文化遗产保护的联防联动机制初步建立，当地民众的保护意识提高。当然该项目也因当地水下文化遗产资料的不全及无切实指导工作的法律法规而进展困难。笔者通过参与该项目的调查与研究，指出各部法规在水下文化遗产保护方面存在盲点，认为水下文化遗产保护工作的开展有赖于文物保护、公安执法、海洋管理、渔业管理和环境保护五大部门法的明文规定和相关行政主管部门的协作 ...

The Cultural Ecology and Non-material Cultural Heritage Protection:Taking Mu Dong Folk Songs as an Example [PDF]
, 2016 口头与非物质文化不可再生，一旦走向消亡，就永远无法恢复。随着经济全球化与现代生活方式的转变，口头与非物质文化遗产日渐式微，受到全社会的广泛关注，但是，在国家政策保护下的口头与非物质文化遗产亦因文化生态环境的改变而发生变形、退化与萎缩。基于此，本文指出，对非物质文化遗产保护的最根本问题是从文化生态的角度保护其原生态性的文化生态环境。 文化生态是借用生态科学的概念、理论、观点和方法研究文化现象的理论，主要研究人类文化与其所处环境之间的密切关系，这里所说的环境不仅指自然环境，同时也包括文化环境 ...

Rare Metals, EarlyView.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Gaoya dianqi, 2015 文中针对直流断路器与柔性直流系统的保护配合进行分析,理论分析了保护配合可行的策略和方式,进而针对不同电压等级下的直流系统实例,结合断路器样机测试结果,利用PSCAD/EMTDC仿真软件分析了极间短路故障时保护配合对系统参数和断路器参数的要求。仿真结果表明,不同保护策略下对系统耐受能力和直流断路器开断性能要求不同,需要根据系统特点选择不同的保护策略。
