Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Fe‐N‐C electrocatalysts are considered promising alternatives to platinum‐based catalysts for advancing the development of metal–air batteries. However, the simultaneous realization of scalable synthesis, hierarchical mass‐transfer pathways, and precise regulation of Fe‐N4 sites remains challenging. Different from conventional Fe‐N‐C synthesis,

Gongye shui chuli羟胺可促进短程硝化的建立。从微生物活性和基因表达的双重视角探究其促进作用。在优化条件下（羟胺质量浓度为20 mg/L，抑制时间为4 h），硝化污泥NO₂--N积累率达68.0%，这主要归因于NH₄+-N氧化活性抑制较弱（40.6%），而NO₂--N氧化活性显著抑制（78.9%）。活性分析结果表明，硝化微生物对羟胺响应存在差异。全程氨氧化菌（Comammox）的NH₄+氧化活性下降65.5%，是整体NH₄+-N氧化活性下降的主要原因，而氨氧化菌（AOB）和氨氧化古菌（AOA）活性变化较小（AOB下降26 ...

GHK‐Cu Delays Aging Through the Repair of Mitochondrial Dysfunction
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Althugh glycyl‐L‐histidyl‐L‐lysine copper (GHK‐Cu) shows antiaging potential, its precise molecular mechanisms remain unclear. Using Caenorhabditis elegans (C. elegans) as an in vivo aging model, we observed that GHK‐Cu extended organismal lifespan and improved stress resilience.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT MoS2 is considered a promising electrocatalyst for the hydrogen evolution reaction (HER) because of its low cost and excellent stability. However, its practical application is severely limited by the scarcity of edge active sites and poor intrinsic electrical conductivity.

Zhejiang Daxue xuebao. Lixue ban, 2013 着重研究了固定床催化条件下对二甲苯与γ-丁内酯连续流动反应的催化活性和选择性.在对几类不同固体酸催化剂考评的基础上，选择H-Beta分子筛为催化剂并考察了反应温度、氮气流量、液体进样量、催化剂的焙烧温度等因素对反应的影响以及催化剂的再生稳定性和导致催化剂失活的主要因素.实验结果表明，H-Beta分子筛对此反应有较高的催化活性和选择性，与γ-丁内酯有关的副反应可能是导致催化剂失活的主要因素，但是失活后的催化剂可直接在固定床中通入空气灼烧反复活化再生，避免了以往液体酸催化中催化剂的一次性使用问题 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Defect engineering plays a crucial role in regulating the active sites and reaction pathways of nanozymes. In this work, oxygen vacancies (Vo) were successfully introduced and stably regulated in ternary CoFeMo layered double hydroxide (CFM LDHs) via a microwave‐assisted hydrothermal strategy, leading to the construction of oxygen‐vacancy‐rich
