一种重整生物质制氢的异质结光催化剂及其制备方法

open access: yes, 2010
一种重整生物质制氢的异质结光催化剂及其制备方法。所述光催化剂的组成为m%WOxSy/CdS(其中x是钨物种中氧的物质的量分数,0≤x≤1;y是钨物种中硫的物质的量分数,0<y≤2;m是钨元素的重量百分数,0<m≤10)。该光催化剂以半导体异质结概念为基础,采用CdS催化剂为载体,通过浸渍法将W的前驱化合物担载在CdS催化剂上;然后采用高温焙烧的方法将W的硫(氧)化物组装在CdS表面,制备出高活性重整生物质制氢异质结光催化剂。本发明实现了廉价半导体光催化剂高效重整生物质制氢 ...

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

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
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.

非晶氧化硅纳米结构的可控生长研究

open access: yes, 2006
非晶氧化硅用可以作为光致发光及光缆材料,也可以应用于光电子器件设计以及生物分析、生物催化、生物分离的载体等领域。纳米氧化硅由于表面严重的配位不足、大的比表面积以及表面欠氧等特点,表现出极强的活性,很容易和环氧状分子氧起键合作用,可以作为树脂基复合材料的增强剂,使环氧树脂的的强度、韧性、延展性大幅度提高。近年来,人们不断合成了不同形貌的氧化硅纳米结构 ...

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

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
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.

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Harnessing social media data to track species range shifts

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.
