Progress and Future Prospect of Electrolyte Additives in Aqueous Zinc‐Ion Battery
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have been regarded as a strong candidate for a new generation of electrochemical energy storage systems because of their high safety, environmental friendliness, low cost and relatively high energy density. However, there are still many challenges for practical application, especially the uncontrolled growth ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Hot deformation bonding (HDB) offers a promising approach to producing superalloy joints with base‐metal‐level strength, provided that interfacial microstructure is reconstructed through dynamic recrystallization (DRX). Current studies on DRX at bonding interfaces neglect actual phase‐contact configurations, obscuring interfacial DRX ...

, 2010 论文以小分子氮氧化物的氧活化作用为重点，研究了用于醇类化合物催化选择氧化的催化新体系。首先设计了TBP-Br2-NaNO3 组成的有机新体系，实现了分子氧与醇类化合物之间的电子传递和氢转移，建立了氧化-还原循环，将脂肪伯醇高选择性氧化成二聚酯。在温和条件下，催化氧化正丁醇的转化率达到92%，正丁酸正丁酯的选择性达95%以上。应用于C5-11 其它伯醇的氧化过程，选择性均超过95%，有效地抑制了酸的生成。研究采用酸激活的方式，设计了在线生成氮氧正离子的催化体系，首次实现氮氧正离子催化的醇类化合物的选择氧化。

Sexuality, Gender &Policy, Volume 9, Issue 4, November 2026.ABSTRACT This study explores how 2SLGBTQ+ youth in Alberta, Canada—the country's most Conservative province—mobilize queer joy as a form of resistance amid rising anti‐queer and anti‐trans policies under a settler colonial, cisheteropatriarchal regime. Drawing from youth‐produced collages, we demonstrate that this visual arts‐based participatory method

, 2018 以凹凸棒石为原料,进行加压酸活化改性,探讨了不同的活化条件如酸用量、液固比、反应时间等因素对凹凸棒石脱色率的影响规律。结果表明,在其它条件相同的情况下,与常压酸活化相比,加压酸活化得到的A-APT对煤油沥青的脱色率提高了约18%。XRD结果发现,加压酸活化凹凸棒石的特征衍射峰与普通酸活化凹凸棒石基本一致,表明凹凸棒石的晶体结构在加压酸活化过程中没有被破坏。BET结果表明 ...

Shuitu Baochi Xuebao, 2011 为了研究不同种类改良剂对铬污染土壤中小白菜生理生化特性的影响,采用盆栽试验监测在不同浓度的铬污染的土壤中小白菜(Brassica parichinensie)的叶绿素含量、超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性以及丙二醛(MDA)含量的变化.研究发现,不同浓度的铬污染土壤中,3种改良剂添加使叶绿素含量及SOD酶活性发生变化并高于对照组而POD酶活性降低,使铬对CAT酶活性的抑制作用得到缓解.石灰、石灰+活性炭用量的增加使MDA含量先降低后升高 ...

Ecological Statecraft for Hegemonic Visions: The Governance of Chengdu Eco‐Zone Over Two Decades
Antipode, Volume 58, Issue 6, November 2026.ABSTRACT This study advances urban political ecology (UPE) by examining how ecological space production has become a key terrain for pursuing a hegemonic project of ecological civilisation in China. ‘Ecological statecraft’ provides a framework for examining how the ecological visions are materialised in the Chengdu Eco‐Zone. The area transformed from a
