Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

玉米不同间作方式对坡耕地水土流失的影响

open access: yesShuitu Baochi Xuebao, 2007
针对云南山地种植措施不合理、水土资源流失严重的现状,进行了玉米间作蔬菜和草带等不同种植方式对坡耕地水土流失影响的研究。结果表明:8月份玉米间作马铃薯的径流量比玉米裸地单作减少37.4%;7月、8月份玉米间作白菜的土壤侵蚀量比玉米裸地单作分别减少46.7%和58.2%;7,8,9,10月份玉米间作混播草带(处理G)侵蚀量分别比玉米裸地单作显著减少68.9%,74.6%,84.5%和82.1%(P〈0.01);玉米间作白菜、间作马铃薯、间作辣椒总侵蚀量分别比玉米裸地单作显著减少47.O%,43.8%和10 ...

Effects of crop species on soil functions and soil multifunctionality are species‐specific

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2354-2369, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil multifunctionality is essential for sustainable agriculture, as soils not only need to support crop growth but also maintain soil biodiversity and sustain other critical ecosystem functions.

间作对玉米根系分泌物及团聚体稳定性的影响

open access: yesShuitu Baochi Xuebao, 2018
通过田间小区试验种植玉米(玉米单作、玉米//大豆、玉米//马铃薯),测定3个生育期(拔节期、大喇叭口期、抽雄期)玉米根系分泌总糖含量、总有机酸含量和土壤团聚体状况,分析间作对玉米根系分泌物及团聚体稳定性的影响。结果表明:玉米根系分泌总糖含量和总有机酸含量随生育期的推移而增加,间作显著提高玉米根系分泌总糖含量和总有机酸含量,玉米//马铃薯>玉米//大豆。在抽雄期,玉米//大豆、玉米//马铃薯相比玉米单作>0.25 mm水稳性团聚体含量(R0.25)分别显著提高6.19%,8.17%;平均质量直径(MWD ...

ZmELF6‐ZmPRR37 module regulates maize flowering and salt response

open access: yesPlant Biotechnology Journal, Volume 22, Issue 4, Page 929-945, April 2024.
Summary The control of flowering time in maize is crucial for reproductive success and yield, and it can be influenced by environmental stresses. Using the approaches of Ac/Ds transposon and transposable element amplicon sequencing techniques, we identified a Ds insertion mutant in the ZmPRR37 gene.

氟对土壤理化性质和玉米生长的影响

open access: yesShuitu Baochi Xuebao, 2007
用盆栽试验研究了外源氟对潮土、黄棕壤pH、容重、玉米干物重和吸钾量的影响,结果表明:氟可以提高土壤pH,使土壤结块,容重增加,孔隙度减少,加入氟1000 mg/kg,黄棕壤和潮土pH分别比对照增加了0.77和0.52,土壤容重分别增加了26.98%和27.72%。氟对潮土过氧化氢酶活性没有影响,加入氟600 mg/kg,氟对黄棕壤过氧化氢酶活性产生明显抑制作用;氟对黄棕壤碱性磷酸酶活性无影响,氟400 mg/kg对潮土碱性磷酸酶活性产生明显抑制。加入氟600 mg/kg,土壤中性磷酸酶活性明显降低 ...
