Synergizing Multi‐Chemisorption Sites and Micropore Confinement in Porous Carbon for High‐Performance Zinc‐Ion Hybrid Capacitors

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Aqueous zinc‐ion hybrid capacitors (ZICs) bridge the gap between high‐energy batteries and high‐power supercapacitors, yet their performance is fundamentally bottlenecked by the micropore confinement effect in carbon cathodes, which restricts hydrated Zn2+ transport and active site utilization.

Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Acid‐Etched Co‐Vacancy‐Tunable CoFeP/N,P‐Codoped Carbon Nanocages for Highly Efficient Alkaline Water Electrolysis

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

多晶硅冶金法除磷的研究进展 [PDF]

open access: yes, 2009
磷是多晶硅中的一种主要杂质元素,目前国内外采用冶金法除磷的工艺主要包括酸洗除磷、合金定向凝固除磷和真空除磷工艺。其中,酸洗除磷工艺可以很有效地去除磷杂质,但仍未达到太阳能级多晶硅小于0.1×10-4%(质量分数)的要求。采用合金定向凝固工艺可以去除80%以上的磷杂质,但目前对凝固后硅中残留溶剂金属的去除方法还有待进一步的研究。通过真空感应熔炼实验已将磷含量从15×10-4%(质量分数)降低至0.8×10-5%(质量分数 ...

COD对生物流化床法降低污泥回流液中氮磷的影响

open access: yesGongye shui chuli, 2009
以市政污水处理厂污泥回流液为研究对象,研究了不同碳、氮、磷水平条件下生物流化床法脱氮除磷的情况,分析了COD/TN与COD/TP对生物流化床脱氮除磷的影响。结果表明,COD对脱氮影响不大,而对除磷具有较大影响。在COD为500mg/L,进水TN为115mg/L时,TN的去除率最大值为72.05%,此时,COD/TN为4.35。在COD为480mg/L,进水TP为11.25mg/L时的去除率较高为36.98%,此时COD/TP为42.67。生物流化床法对高浓度氮磷污泥回流液具有一定的脱氮除磷效果 ...

淹没式贝壳填料生物滤池的除磷效应 [PDF]

open access: yes, 2003
 探讨了以贝壳为填料的生物滤池的除磷机理,研究了影响除磷效果的主要因素。静态试验结果表明:在酸性条件下贝壳能够通过化学作用去除水中的磷。连续试验结果显示:当控制水力停留时间在5h以上时贝壳显示出较高的除磷效率;当贝壳与陶粒的填充高度之比为2∶1时除磷效果最佳,除磷率可达75%~85%

碳源对除磷颗粒污泥除污效能和微生物特性的影响

open access: yesGongye shui chuli, 2023
采用厌氧-好氧间歇运行模式,在SBR反应器中分别以丙酸钠、乙酸钠、葡萄糖、蔗糖为单一碳源对生物除磷颗粒污泥进行培养驯化,并考察不同碳源下除磷颗粒污泥对水中磷的去除效果,同时结合高通量测序,探究不同碳源驯化的生物除磷颗粒污泥中微生物种群结构的变化情况。结果证明:碳源为丙酸钠时,系统对磷的去除效果最佳。高通量测序结果表明:碳源对除磷颗粒污泥的微生物种群结构影响显著,以丙酸钠为碳源的颗粒污泥中聚磷菌(PAOs)占比最高;以乙酸钠为碳源的颗粒污泥聚糖菌(GAOs)占比最高;以蔗糖为碳源的颗粒污泥PAOs含量最低,
