Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Thermally driven hydrogenation of CO2 to light olefins (C2=–C4=) using metal oxide‐zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid‐site inactivation, and surface carbon poisoning.

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Shuitu Baochi Xuebao, 2016 为了探究有限灌溉对绿洲沙地春玉米农田耗水特征及水分利用效率的影响，利用中子仪结合烘干秤重法连续监测了河西走廊荒漠绿洲沙地春玉米不同生育期农田土壤水分动态，分析了玉米农田日耗水量动态与土壤蒸散及作物水分利用效率。结果表明，整个生育期除播种-五叶期和拔节-孕穗期外，所有有限灌溉处理及充分供水对照间日耗水量均无显著差异（P＞0.05），各生育时段内日耗水量随生育过程呈由小到大再由大到小的变化趋势，其峰值出现在吐丝~灌浆中期且高达6.8～10.0 mm/d。灌水最少但产量最高的有限灌溉处理 ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Elephant barrier behaviors in response to conflict mitigation fences
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Human–wildlife conflict is a major conservation issue, particularly in lower income countries, where it affects marginalized people and leads to the extirpation of threatened species. Managers increasingly use fences to reduce this conflict but lack evidence on the effectiveness of these barriers, especially on whether this reduces the number ...

Integrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Shuitu Baochi Xuebao, 2020 研究旨在探究不同小麦品种对深层土壤水分利用差异及其对产量、水分利用效率的影响。试验于2017—2019年在陕西长武进行，试验为品种、播量双因子试验，品种为主处理（A为"长旱58"，B为"长航1号"），播量为副处理（10：播量150 kg/hm2，12：播量180 kg/hm2），分析不同处理对冬小麦各生育期土壤水分消耗及其产量和水分利用效率的影响。结果表明：在不同的试验年，与"长旱58"相比，"长航1号"对土壤水分的消耗均显著增加。与此同时，相比"长旱58"，"长航1号"的小麦穗粒数、收获指数 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

基于APSIM模型小麦-玉米不同灌溉制度作物产量和水分利用效率分析
Shuitu Baochi Xuebao, 2021 针对海河平原地下水位持续下降和维持小麦—玉米两熟较高产量之间的矛盾，对不同降水年型小麦—玉米不同灌溉制度下产量和水分利用效率（WUE）进行模拟分析，结果对平衡该区域地下水可持续利用与粮食生产提供重要科学决策依据。利用研究区域站点长时间序列气象数据，以小麦不同水分处理地上部生物量、叶面积和周年土壤水分动态田间试验数据为基础，对APSIM小麦玉米遗传参数和土壤水分等相关参数进行了校准和验证。利用校准和验证的APSIM模型，对不同降水年型小麦—玉米不同生长阶段水分亏缺指数（CWDI）进行了分析 ...
