Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.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 ...

Shuitu Baochi Xuebao, 2000 皇甫川流域１９７９年以前水土保持治理断断续续，治理面积也比较小，１９８０年以后水土保持治理得到了稳步发展，１９９７年各种水土保持治理面积近９万ｈｍ＾２。水土保持治理对皇甫川流域的洪水特性及其持征等生态环境问题产生了一定的影响，主要表现在：治理后不可利用流量的天数越来越多，洪水的含沙量降低，流速增大，流量增大，动量增大以及洪水单位动量冲刷厚度减小，而单位动量淤积厚度增大等 ...

Rare Metals, Volume 45, Issue 3, March 2026.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

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT In conventional piezoceramics, the coordinated change between the dielectric constant (εr) and the piezoelectric charge constant (d33) usually limits the piezoelectric voltage constant g33 (g33 = d33/εr), a critical figure of merit for piezoelectric sensors.

Shuitu Baochi Xuebao, 2019 川西高山峡谷区森林较高的地表枯落物储量可能具有较好的水文生态效益，但缺乏研究关注。以川西高山峡谷区6种森林为对象，在雨季调查了不同森林地表枯落物的持水和失水特性。结果表明：（1）川西高山峡谷区林地枯落物蓄积量与最大持水量和有效拦蓄量呈显著正相关，林地枯落物蓄积量为6.90~17.49 t/hm2，最大持水量为1.64~5.42 mm，最大持水率为138.18%~330.09%，有效拦蓄量为0.53~3.33 mm，有效拦蓄率为77.57%~203.02%。（2）相对其他森林，亮叶桦（Betula ...

Shuitu Baochi Xuebao, 2008 对3种引进草种的生物量、枯落物量、土壤的容重、孔隙度、自然含水量、毛管持水量、饱和含水量、机械组成、有机质含量、渗透性能和抗蚀能力等进行了测定和分析。结果表明,3种引进草种的水土保持效果依次为纳罗克非洲狗尾草>威提特东非狼尾草>沙弗雷肯尼亚白三叶草,纳罗克非洲狗尾草的持水能力和土壤改良性能最好,是水土保持效果最佳的牧草,可以推广种植,其次是威提特东非狼尾草。
