The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Synthesizing beaver coexistence messaging with the capability, opportunity, and motivation behavior model

Conservation Biology, EarlyView.
Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Study on Flame Retardant Resin Matrix Composites [PDF]

, 2015
苯并噁嗪（BOZ）树脂是一种新型热固性树脂基体，其固化过程体积接近零收缩，耐热性优良，还拥有与传统酚醛树脂类似的优异阻燃性能。为了将BOZ树脂基复合材料应用在更高阻燃要求的场合，还需对其进行阻燃改性。黄麻纤维具有资源可再生、综合性能良好、价格低廉等优点，其复合材料在汽车内饰、轨道交通、建筑家装等领域有巨大的应用前景，但黄麻纤维易燃，必须对其进行阻燃改性。本文利用聚磷酸铵（APP）和碳纳米管（CNT）对BOZ树脂及其玻璃纤维（GF）复合材料进行了阻燃改性，以及利用水性 ...

气体分解产物和局部放电测试技术在SF₆电气设备状态诊断中的应用

Gaoya dianqi, 2014
主要介绍了SF6气体分解产物、局部放电测试这2种检测技术在SF6电气设备状态诊断中的几起成功应用的案例。这些案例各有特点:SF6气体分解产物异常但不存在局部放电信号;SF6气体分解产物正常但存在局部放电信号;SF6气体分解产物异常且存在局部放电信号;SF6气体分解产物异常但无法采用局部放电测试技术进行检测。通过解体,均验证了设备存在缺陷。因此,SF6气体分解产物、局部放电测试技术在SF6电气设备潜伏性故障诊断方面具有广阔的应用前景。

Study on The High-Voltage Electrolytes and Interfacial Electrochemistry of Li-ion Battery [PDF]

, 2017
开发高电压高比容量正极材料是发展高能量密度锂离子电池的重要途径。然而，材料结构变化、过渡金属离子的溶出以及常规碳酸酯电解液在高电压下的持续氧化，电极/电解液界面的不稳定性等将导致材料循环性能的快速衰退。同时，电解液分解产生大量气体和热量可能引发安全问题亦严重制约着锂离子电池的发展。因此，开发新型高电压电解液以拓宽电解液的电化学稳定窗口及高电压条件下稳定正极/电解液界面的研究迫在眉睫。 本文从发展高电压溶剂和功能型添加剂两种实现电解液高电压化的有效途径出发，以腈类化合物和新型膦腈类化合物为研究对象 ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

1.考察了将离子液体分别引入沉积-沉淀法和生物还原法制备负载型金催化剂（Au/TS-1）的过程，并将所获催化剂用于H2、O2共存时的丙烯气相环氧化过程。沉积-沉淀法引入离子液体后，制备过程中离子液体的用量、体系的pH以及Au负载量均会影响所获催化剂的催化性能。离子液体的引入可以提高Au的有效负载量，并在一定程度上提高催化剂的催化性能，但Au负载量的提高是有限的，而且Au的有效利用率偏低。将离子液体引入生物还原法后，考察了制备过程中离子液体的种类、生物质的种类和生物质浓度的影响 ...
