Gongye shui chuli, 2022 在没有NO2-或短程硝化的情况下，厌氧氨氧化菌（AnAOB）可以微生物电解池（MECs）的阳极为电子受体氧化NH4+-N，这种电极驱动型厌氧氨氧化（E-Anammox）可有效解决传统厌氧氨氧化（Anammox）电子受体NO2-供给不稳定的问题。但MECs系统常用的铁阳极易发生腐蚀板结，导致电极导电能力下降、电子利用率降低。针对铁阳极易腐蚀的问题，对普通铁阳极进行包覆改性制备改性铁阳极，将改性铁阳极和普通铁阳极分别与MECs系统耦合加载于Anammox反应体系中，考察了2个反应体系中氨氧化、系统阻抗值 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

四川大学学报. 自然科学版, 2007 以不同Cd2+浓度对土培小麦进行处理,分别在拔节、抽穗、灌浆初期以及灌浆中期,分析不同浓度Cd2+胁迫下活性氧及酶促和非酶促抗氧化系统的变化.结果表明,随着小麦生育进程的变化,Cd2+胁迫使O2.-、H2O2和MDA含量增加,且生育前期的增长量明显大于后期;各生育时期的抗氧化酶和抗氧化物也出现不均衡变化:抽穗—拔节期间,SOD活性升高,CAT保持稳定,酶促抗氧化系统对活性氧的清除作用显著;灌浆期后,SOD、CAT活性均比对照有所下降,而抗坏血酸-谷胱甘肽氧化还原途径中的APX、GR活性以及AsA ...
