紫色土区植物篱篱前淤积带土壤团聚体稳定性特征研究

open access: yesShuitu Baochi Xuebao, 2018
为探讨紫色土区植物篱篱前淤积带土壤团聚体的稳定性,试验以该淤积带土壤为研究对象,设置了10°对照小区(T1)、10°新银合欢植物篱小区(T2)、10°香根草植物篱小区(T3)、15°对照小区(T4)、15°香根草植物篱小区(T5)等5个处理,采用萨维诺夫法测定了风干团聚体和水稳性团聚体的组成状况,以保存机率、稳定性指数、PAD(结构体破坏率)、MWD(平均重量直径)、GMD(几何平均直径)、MWSSA(平均重量比表面积)、CS(偏度系数)和CE(峰凸系数)等为评价指标,分析了不同坡度 ...

Ultrafast Catalytic Decomposition Reaction Using a ZIF‐67@Cellulose Nanofiber Composite‐Based Cobalt/ Nitrogen Co‐Doped Nanoporous Carbon for Water Treatment

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...
