Rare Metals, EarlyView.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Rare Metals, EarlyView.ABSTRACT TiFe‐based hydrogen storage alloys have garnered significant attention because of their cost‐effectiveness, high hydrogen capacity, and favorable hydrogen absorption/desorption characteristics. However, practical application was limited by activation challenges and sensitivity to environmental poisoning.

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

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

Probability Safety Analysis of Simplified CPR1000 Main Feedwater System and AP1000 Passive Containment Cooling System [PDF]
, 2016 随着数字化仪控系统在核电厂中得到越来越多的应用，其可靠性对核电安全也越来越重要。传统概率安全分析方法已在模拟仪控系统中得到广泛应用，但在分析具有新设备和新技术的数字化仪控系统时还存在不足。动态概率安全分析方法中，Markov/CCMT是较为符合数字化仪控特性的概率安全分析方法之一。 本文主要是应用故障树、Markov和Markov/CCMT三种方法对简化CPR1000主给水系统和简化AP1000非能动安全壳冷却系统分别进行安全分析，其中简化CPR1000主给水系统在设置故障时偏重于数字类故障 ...

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Discussion on Using Character as A Method of Oral Evidence Authentication [PDF]
, 2016 言词证据的鉴真是有难度的。一方面，言词证据所反映的案件信息是以 主体对事实进行初步加工为前提，通过言词陈述的方式向第三人传递。因 此，它的证明力很大程度上受到言说人主观因素的影响。另一方面，言词证 据包含的信息多且丰富，是还原案件事实的第一手资料。和实物证据相比， 司法人员更重视对“口供”等言词的获取，有时因为存有过分追求真相的不 良心态，又实施了非法取证的行为。因此，它的证据能力相当程度上受到取 证者的因素的影响。然而，实践中以书面形式审查言词的鉴真方式，并不能 帮助法官排除这些主观因素 ...

Nations and Nationalism, EarlyView.ABSTRACT This study presents one of the first comparative analyses of digital nationalism on social media. Using a computational mixed‐method approach—combining supervised, computer‐assisted content analysis with network modelling—it analyses 64,541 tweets from Twitter and 91,063 posts from Weibo surrounding a shared geopolitical flashpoint: President ...

Dianci bileiqi, 2020 城市配电线路建设会存在架空线路与埋地电缆混合传输现象,需要合理分析混合传输系统雷击可靠性以进行针对性防护。通过EMTP软件建立架空线路与埋地电缆混合传输系统模型,利用事件树方法估算系统雷击可靠性,分析电缆避雷器安装方式、杆塔接地电阻、埋地电缆长度等因素对系统雷击可靠性影响,最后讨论缩短故障修复时间提高系统雷击可靠性效果。研究结果表明:埋地电缆两端均安装避雷器时,系统雷击可靠性最高,略高于仅在一端安装避雷器情况。系统雷击可靠性随着线路杆塔接地电阻或埋地电缆长度的增加而降低 ...
