【摘要】

：

通过水热法用Cu2+置换酸活化凹凸棒石黏土(Pal)八面体阳离子实现晶格重建(Cu-Pal),过量的Cu2+经过溶液pH值调变和煅烧后,在Cu-Pal表面原位生长出氧化铜量子点(CuO QDs),从而制备出CuO QDs/Cu-Pal纳米复合材料,并将其应用于光催化固氮,考察了Cu2+用量对凹凸棒石微观形貌、光学性质和能带结构的影响.结果表明:Cu-Pal具有更窄的带隙,将光响应范围从紫外光拓展到可见光.当Cu2+含量超过5％(质量分数)时,Cu-Pal表面的CuO QDs由于窄带隙(1.2 eV)增强

An improved formula for incipient sediment motion in vegetated open channel flows

Quantifying incipient sediment motion in vegetated open channel flow is pivotal for estimating bed load transport and the aquatic ecological environment in rivers. A new formula is developed to predict the critical flow velocity for incipient sediment mot

Improved bridge pier collar for reducing scour

This study performed a bridge pier collar comparison for the purpose of reducing scour, while intro-ducing a new collar design. The new collar, referred to as Collar Prototype Number 3, was designed based on an equilibrium scour hole and provides a method

Heavy mineral composition and texture of the recently formed fluvial delta sediment of Lake Nasser/N

Surficial sediment samples collected from the recently formed fluvial delta in Lake Nasser/Nubia (Egypt and Sudan) in conjunction with data on bottom current and depth soundings are examined to interpret hydraulic-sorting processes and transport/depositio

Characterizing and identifying bedforms in the wandering reach of the lower Yellow River

The lower Yellow River (LYR) is a fully alluvial system with a fine-grained bed that has a high proportion of silt. Bathymetric survey data collected with a Multi-Beam Echo Sounder (MBES) from the wandering reach of the LYR indicates that the bedforms are

Impacts of land use and land cover changes on hydrological processes and sediment yield determined u

Land use and land cover (LULC) changes strongly affect local hydrology and sediment yields. The current study focused on a basin in the Brazilian Amazon and had the following three objectives:(1) to perform an effective diagnosis of flow and sediment yiel

Sediment dynamics in the mudbank of the Yangtze River Estuary under regime shift of source and sink

The southeastern portion of the Yangtze River Estuary (or Yangtze Estuary) was considered to be the deposition center and the mudbank of the Yangtze River Delta. As the fluvial sediment supply began to decline in the 1980s and the reduction accelerated af

Swimming behavior of juvenile silver carp near the separation zone of a channel confluence

Knowledge of locomotion of fish near river confluences is important for prediction of fish distribution in a river network. The flow separation zone near the confluence of a river network is a favorite habitat and feeding place for silver carp, which is o

Abiotic predictors of fine sediment accumulation in lowland rivers

The delivery of excessive fine sediment (particles < 2 mm in diameter) to rivers can cause serious deleterious effects to aquatic ecosystems and is widely acknowledged to be one of the leading con-tributors to the degradation of rivers globally. Despite a
