, 2023 黄河三角洲地区土壤盐渍化严重,加之冬春季节降雨量少,淡水资源匮乏,耕地冬春休耕现象普遍。于2020年9月-2021年10月,以冬春休耕为对照,研究种植翻压毛叶苕子对土壤理化性质、活性有机碳组分动态变化和后茬作物玉米产量的影响,以期为覆盖植物在黄河三角洲地区盐碱地产能提升方面的应用提供参考。结果表明,在1年试验期内,与冬春休耕相比,种植毛叶苕子可以降低土壤EC,提高易氧化有机碳(ROC)含量,翻压后则显著降低pH,并提高土壤养分和活性有机碳含量。与休耕相比,试验期内毛叶苕子处理平均pH降低0.12 ...

长期覆膜旱地苹果园表层土壤“隐性”退化下活性有机碳与酶活性差异
Shuitu Baochi Xuebao, 2021 为探明陇东旱塬雨养农业区旱作节水措施下黄绵土物理稳定性机制和化学活性机制，揭示表层土壤有机碳贮存对土壤物理"隐性"退化的响应机制。以陇东旱塬区不同覆膜年限（2，4，6年）的苹果园表层土壤（0—20 cm）为对象，对土壤物理性状、质地分级进行判断，监测微生物量碳（MBC）、易氧化有机碳（EOC）、颗粒有机碳（POC）、可溶性有机碳（DOC）等指标的动态变化，表征土壤有机碳变化趋势，借助β-1，4-木糖苷酶（βX）、β-1，4-葡萄糖苷酶（βG）、纤维二糖水解酶（CBH）活性表征土壤碳代谢循环特性 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Rare 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.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.
