Rare Metals, EarlyView.ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Preparation of Indium Tin Oxide Nanopowders and Study of their Surface Plasmon Resonances and Applications as Heat Isolation Materials [PDF]
, 2015 氧化铟锡（ITO）具有优异的高电导和高可见光透光率性质，已广泛应用于透明导电氧化物（TCO）薄膜材料。有关ITO材料的研究，大多集中于其高载流子浓度导致的高电导性质。虽然ITO纳米粉体由于其高载流子浓度，因此具有高的近红外吸收特性，作为热阻隔材料有应用潜力，但，ITO热阻隔材料的相关研究，主要是成膜工艺、膜层性能等方面；而对于关键的基础问题，即，ITO纳米粉体材料的基础问题，尤其是等离子共振（SPR）吸收特性方面的研究尚缺。等离子共振吸收的影响因素，理论上虽然给出了指导，但，针对ITO纳米粉体 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Primary study of the electrochemical ammonia compression technology based on the fuel cells [PDF]
, 2016 氨是目前广泛使用的良好的制冷剂，具有价格低廉、压力适中、单位制冷量大、放热系数高以及流动阻力小等优点。几乎所有的食品加工的冷却设备都有用到氨，比如冷库、冰箱和空调等。氨气压缩机是空调制冷循环系统的核心部件，作为关键核心技术的压缩机技术，它的研发和创新具有举足轻重的作用。 本研究提出了一种电化学式氨气压缩技术并进行了初步探究，将常压的氢气与氨气的混合气体用电化学的方法进行压缩，得到高压的氢气与氨气的混合气体，该压缩装置类似于质子交换膜燃料电池，核心结构为膜电极。 选用Nafion117 ...

Integrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Gaoya dianqi, 2014 由于SF6气体的温室效应,减少SF6气体的使用具有深远的社会意义,用SF6/N2混合气体取代纯SF6气体作为高压电器设备的绝缘介质是减少使用SF6气体的有效措施。介绍了SF6/N2混合气体的优点。从气体放电理论出发,对不同比例SF6/N2混合气体的绝缘性能进行了分析,结果表明:SF6体积分数仅为20%的SF6/N2混合气体击穿强度为相同气体压力纯SF6的70%左右;若SF6体积分数为20%的SF6/N2混合气体的击穿强度要达到纯SF6气体的击穿强度,其总压力应为纯SF6气体的1.4倍 ...
