ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

为探明建筑回填土条件下草坪草种植的适宜性以及再生水灌溉对草坪草生长和土壤理化性质的影响情况,选用黑麦草为试验对象,通过室内盆栽试验的方式,设置清水灌溉、再生水灌溉、清水—再生水交替灌溉3个处理,研究了呼和浩特市建筑回填土灌溉再生水对草坪草生长及土壤理化性质的影响。试验发现:(1)与清水灌溉相比,清水—再生水交替灌溉、再生水灌溉下的草坪草生长速率分别增长了23%,34%。(2)各处理草坪草在质地、盖度、均一性方面的得分表现为再生水灌溉>清水—再生水交替灌溉>清水灌溉,但差异性不显著(P>0.05)。(3 ...

Engineering 2D Materials for High‐Current‐Density Electrocatalytic Water Splitting
ABSTRACT Water electrolysis is a key method for sustainable hydrogen production, using water as an abundant resource. However, efficient and stable operation at high current densities remains challenging due to energy losses, catalyst degradation, and limited ion–electron transport.

通过田间试验,分析了再生水灌溉对番茄果实品质、重金属以及土壤重金属的影响。结果表明,番茄果实中蛋白质、维生素C、有机酸含量为清水灌溉(QG)〉清水再生水交替灌溉(HG)〉再生水灌溉(zG),差异显著;番茄果实中Cr,Cd,Pb的含量随再生水灌溉量的增大而增大,差异不显著,没有造成重金属的累积,而且远低于国家无公害蔬菜安全标准。土壤中的重金属含量差异不显著,远低于国家土壤质量标准。因此,经过二级处理后的再生水,短期灌溉除了降低番茄部分品质外,不会造成重金属在番茄果实和土壤中的累积。

ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Research on the Feasibility of Using Coagulation-filtration to Treat Living Wastewater for Green Land Irrigation [PDF]
通过小型模拟试验,研究采用“混凝过滤”方法处理后的生活污水浇灌园林绿地后,对绿地植物生长及环境安全产生的影响。研究表明:生活污水经混凝过滤去除悬浮物后浇灌绿地,不但补充了水分,还为植物提供了一定的营养成分,使植物生长茂盛。生活污水经过80 cm厚的土壤层净化后,其悬浮物、氨氮、无机磷、有机物(CODCr)的去除率分别为84%、97%、90%、68.7%,下渗水的浊度平均为0.5 NTU,氨氮、磷酸盐、有机物(CODCr)平均浓度分别为0.4 mg.L-1、0.06 mg.L-1、13.7 mg.L-1 ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

为揭示再生水不同灌溉模式下土壤结构性质及导水性能的差异。通过室内模拟土柱入渗试验,以清水灌溉为对照(CK),研究了再生水持续灌溉(RW)、再生水—清水混合灌溉(RW-2)及再生水—清水交替灌溉(ARW)3种灌溉模式对土壤容重、总孔隙度、团聚体稳定性、入渗率及饱和导水率的影响。结果表明:相比CK,各处理容重呈降低趋势,总孔隙度增加,但差异均不显著;再生水灌溉促进潮土>1 mm粒级团聚体向1 mm粒级水稳性团聚体含量对潮土结构稳定性贡献最大;再生水3种灌溉模式下潮土入渗率分别显著增长80.00%~260 ...
