群体猝灭技术在控制MBR生物污染中的研究进展

open access: yesGongye shui chuli, 2021
膜生物反应器(MBR)广泛用于处理市政污水,但膜污染仍是MBR的应用瓶颈。基于微生物群体感应(QS)理论的群体猝灭(QQ)技术是一种具有较好前景的膜污染控制方法。QQ技术可干扰微生物的QS系统,进而抑制胞外聚合物的分泌和生物膜的形成,从根本上达到控制MBR生物污染的目的。对利用QQ技术控制MBR生物污染的研究进展进行总结,提出该技术面临的挑战,并对今后采用QQ技术减缓膜污染的研究进行展望。

Si Alloying Enables High Performance in Ce‐Substituted Hot‐Deformed Nd–Fe–B Magnets

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT High levels of Ce substitution typically degrade the magnetic performance of hot‐deformed Nd–Fe–B magnets, posing challenges for developing resource‐efficient permanent magnets. Here, we demonstrate that minor Si alloying in (Nd0.6Ce0.4)‐Fe‐B hot‐deformed magnets effectively compensates for this degradation and enables enhanced magnetic ...
