Comparison of empirical models and laboratory saturated hydraulic conductivity measurements
, 2014 Numerous methods for estimating soil saturated hydraulic conductivity exist, which range from direct measurement in the laboratory to models that use only basic soil properties. A study was conducted to compare laboratory saturated hydraulic conductivity

Advanced Science, EarlyView.Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

, 2022 흙의 포화투수계수는 지반구조물의 안정성 평가에 매우 중요한 흙의 물성치이지만 높은 불확실성을 가지기 때문에 높은 성능을 가진 예측모델의 구축이 상대적으로 어렵다. 본 연구에서는 인공신경망을 이용하여 11가지 흙에 대한 포화투수계수 예측모델을 구축하고 그 성능을 평가하였다. 1~3개의 은닉층수와 6~54개의 노드수의 10가지 시나리오에 대한 ANN모델을 구축하여 각각의 모델의 성능을 평가하고 최적의 모델을 도출하였다.

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures
Advanced Science, EarlyView.Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Journal of Environmental Engineering and Landscape ManagementSoil sampling and in situ measurements were conducted at 24 locations at three time points from May 2015 to April 2016. The statistical analysis showed that the variabilities of soil water content and soil penetration were moderate, while particle size ...

Sputtering Mechanism of an Unsintered Organic–Inorganic Sputtering Target for Perovskite Solar Cells
Advanced Energy Materials, EarlyView.An unsintered MAPbI3 sputtering target fabricated via a mechanochemical route enables large‐area vacuum deposition of perovskite absorber layers, while revealing an ion–photon coupled decomposition mechanism that governs target erosion and film composition under RF plasma exposure.

Effect of soybean roots and a plough pan on the movement of soil water along a profile during rain
Applied Water Science, 2019 The movement of water into soil is the primary driving force in nutrient transport for crops, and the laws governing this movement can be affected by crop roots and plough pans.

Prediction of biopore- and matrix-dominated flow from X-ray CT-derived macropore network characteristics [PDF]
Hydrology and Earth System Sciences, 2016 Prediction and modeling of localized flow processes in macropores is of crucial importance for sustaining both soil and water quality. However, currently there are no reliable means to predict preferential flow due to its inherently large spatial ...

Saturated Hydraulic Conductivity and Textural Heterogeneity of Soils [PDF]
, 2017 Abstract. Saturated hydraulic conductivity Ksat is an important soil parameter that highly depends on soil's particle size distribution (PSD). The nature of this dependency is explored in this work in two ways, (1) by using the Information Entropy as a heterogeneity parameter of the PSD and (2) using descriptions of PSD in forms of textural triplets ...
