新型微电解材料降解印染废水研究

open access: yesGongye shui chuli, 2018
针对传统微电解材料只适用于酸性废水的局限,对铁碳微电解材料进行改性,用于甲基橙模拟印染废水的处理,确定了处理的最佳工艺参数。结果表明:新型微电解材料在pH为4~5、11~12内对甲基橙均有较好的降解效果,最佳反应时间为3 h,最佳投加量为340 g/L。采用印染退浆废水进行对比实验,结果表明:新型微电解材料在COD去除率和可生化性提高方面均明显优于市售微电解材料,经新型微电解材料预处理后B/C提高了近5倍。

Multifunctional Integration in a Monolithic Biomass Carbon: A Triple‐Synergistic Host for Advanced Lithium–Sulfur Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

MFCs降解藻类生物质的预处理方法研究进展

open access: yesGongye shui chuli, 2022
微生物燃料电池(MFCs)能够在降解有机物的同时将化学能转化为电能,近年来其独特的能源环境效应在降解藻类生物质方面引起广泛关注。然而,成分复杂的藻类细胞壁会阻碍藻类生物质在微生物燃料电池中的降解。为了提高微生物燃料电池降解藻类生物质的效能,通常需要对藻类生物质进行预处理,破坏藻类细胞壁使生物基质释放,并将难降解的大分子有机物分解为易降解的小分子有机物。综述了目前应用于微生物燃料电池降解藻类生物质的预处理方法,包括机械法、加热法、微波法和超声波法等物理预处理法,酸、碱、氧化等化学预处理法,酶或微生物细胞 ...

Fe-Cu-C三元微电解法预处理含油废水的实验研究

open access: yesGongye shui chuli, 2012
利用微电解技术处理某石化企业含油废水,考察了m(Fe)∶m(Cu)∶m(C)、反应时间、初始pH对废水油去除率的影响。实验结果表明,Fe-Cu-C三元微电解反应体系的处理效果和速率均明显优于Fe-C二元微电解反应体系,且Fe-Cu-C三元微电解处理有更宽的pH适应范围;Fe-Cu-C三元微电解的最佳工艺参数为m(Fe)∶m(Cu)∶m(C)=2∶1∶1,反应时间为45 min,初始pH=4,在最佳条件下,除油率可达56%左右。

Heterointerfaces and Sulfur Vacancies in MXene/MoS2@C for Boosted Ultra‐Broadband Electromagnetic Wave Absorption and Infrared Stealth Response

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

Influence of Alkaline Earth Barium on the Microstructure, Corrosion Behavior, and Cytocompatibility of Biodegradable Zinc

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.
