Lignin‐Derived Carbon Quantum Dots as Hole‐Trapping Promoters in LCDs/Bi‐MOF/ZIS With S‐Scheme Heterojunction for Efficient Photocatalytic Hydrogen Peroxide Production in Pure Water

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Electron–Hole Dual Cocatalyst Promoted ZnIn2S4 for Photocatalytic H2 Evolution Coupled With Benzyl Alcohol Oxidation

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Modulating Oxygen Vacancies via Ag Induced Interfacial Electron Transfer in SnO2 for CO2 Electroreduction

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Regulating oxygen vacancies (Ov) in SnO2 to facilitate high‐efficiency carbon dioxide electroreduction reduction reaction (CO2RR) is still a significant challenge. Therefore, a strategy based on Ag‐induced interfacial electron transfer was proposed to modulate Ov in SnO2 for CO2 electroreduction. The prepared Ag/SnO2 with an optimal Ov content

晚期胰腺癌患者血清CA125,CA199水平与肝转移的关系

open access: yesZhongguo shiyan zhenduanxue, 2017
目的分析晚期胰腺癌患者血清CEA,CA199水平与肝转移的关系,探讨胰腺癌肝转移的危险因素。方法选取101例胰腺癌患者,主要根据有无肝转移分组,肝转移70例,无肝转移31例。采用化学发光免疫法对其血清标本中癌胚抗原(CEA)、糖抗原19-9(CA19-9)、糖抗原125(CA125)、糖抗原72-4(CA72-4)、细胞角蛋白21-1(CYFRA21-1)等项目进行检测。结果血清CA19-9、CA125水平的增高与胰腺癌肝转移具有相关性 ...

Calcium‐Engineered Copper/Palladium Nanozyme With Reactive Oxygen Species/Nitric Oxide Dual‐Burst for Enhancing Immunotherapy via Multiple‐Inducing Calcium Overload

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Calcium overload‐induced immunogenic cell death (ICD) holds great potential in antitumor immunotherapy, and it is a critical strategy for regulating multiple intracellular Ca2+ channels through inhibiting the endogenous Ca2+ efflux and promoting the exogenous Ca2+ influx.

血清miR-21对结直肠癌肝转移预测价值的评价

open access: yesZhongguo shiyan zhenduanxue, 2018
目的探讨血清miR-21对结直肠癌肝转移预测的诊断价值,以期为临床的结直肠癌肝转移的预测提供一种潜在的辅助诊断方法。方法检测146例晚期结直肠癌无肝转移患者和124例晚期结直肠癌伴肝转移患者血清中CEA的含量和miR-21的相对表达值,评价其单独检测和联合检测对于结直肠癌肝转移的预测的诊断价值。结果与结直肠癌无肝转移组相比,结直肠癌伴随肝转移组的CEA和miR-21均显著升高 ...

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...
