水处理中单线态氧生成方式的研究进展

open access: yesGongye shui chuli, 2023
在高级氧化过程中,相比于羟基自由基、硫酸根自由基可无差别地氧化降解有机污染物的性质,活性氧粒子单线态氧可以有选择性地降解特定有机污染物,这一特点为处理复杂水体污染提供了另一种可行方案。分别从光促进、通过活性中间体以及在催化材料中构造特殊结构这3个角度,系统梳理了当前文献中报道的单线态氧生成的主要途径,并就各生成途径的优缺点做了比对。光促进途径涉及气-液-固三相反应,光能利用率需进一步提高,通过活性中间体生成单线态氧的途径往往不易准确把握活性中间体的含量。与这2种生成方式相比 ...

温度对套管环氧胶浸纸绝缘频域介电响应的影响研究

open access: yesDianci bileiqi, 2023
为研究温度对环氧胶浸纸绝缘套管频域介电响应特性的影响,开展了环氧胶浸纸绝缘样片在高低温(10℃~120℃)循环下的频域介电谱测试,绘制了不同循环次数下环氧胶浸纸绝缘样片的频域介电响应特性曲线。结果表明:随着高低温循环次数的增加,在120℃时介质损耗因数、复合电容实部和虚部频谱曲线整体向上和高频方向移动,在10℃时在高频区域下介质损耗因数和复合电容虚部的频谱曲线整体向上移动,而复合电容实部的频谱曲线基本保持不变。10℃和120 ...

An Organo‐Pt(II) Photosensitizer With Robust Photo‐Assisted Antibacterial and Wound Recovery Performances in Diabetic Mice Wound Model

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The pathogenesis of diabetic foot ulcers is complex, often involving polymicrobial infection and persistent inflammatory responses, which lead to delayed or nonhealing wounds, posing a formidable clinical challenge. Existing photodynamic therapy reagents and traditional treatments generally address only a single pathological aspect, and the ...

A Dual‐Function Mitochondria‐Targeted Polyoxometalate Nanomicelle Boosts Pyroptosis‐Dependent Antitumor Immune Response in Triple‐Negative Breast Cancer

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...

10 kV串联间隙金属氧化物避雷器在配电网防雷中的优化配置

open access: yesDianci bileiqi, 2020
主要通过EMPT电磁暂态分析软件对10 kV串联间隙金属氧化物避雷器在配电网系统中安装使用时进行仿真分析,首先进行PS15绝缘子及10 kV环电极避雷器及穿刺避雷器产品的U50%放电电压试验,再仿真分析在不同接地条件下只安装单相产品对同级其它相绝缘子的影响及只安装一级对相邻级绝缘子的影响,分析得出无论是直接接地还是单独接地,当雷电流超过40 kA后均会造成相邻相或相邻级的绝缘子闪络,建议全线安装或在雷击严重区段及易击点全线安装10 kV串联间隙金属氧化物避雷器,不需单独设置接地,条件允许可在末端设置接地。

Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−
