Evaluation Model of Soil Water Characteristic Curve of Red Clay Based on Dielectric Theory [PDF]

长江科学院院报
[Objective] The soil water characteristic curve (SWCC) can effectively reflect the relationship between soil water suction (matric potential) and water content, yet conventional testing methods pose challenges for the calibration of in situ soil ...

An Electrowetting Pump

Advanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Predicting the Soil Moisture Characteristic Curve from Practicle Size Distribution witb a Simple Conceptual Model [PDF]

, 2011
Indirect methods for predicting the soil moisture characteristic curve (SMC) from the particle size distribution (PSD) often rely on empirical coefficients, which limits their applicability to independent data sets.

One-stage Bayesian experimental design optimization for measuring soil-water characteristic curve

Yantu gongcheng xuebao, 2023
The direct measurements of soil-water characteristic curve (SWCC) are often costly and time-consuming. Therefore, only a limited number of test data can be obtained from a single SWCC test, based on which the estimated SWCC inevitably produces ...

Reconfigurable Au Nanoparticle Monolayers on Regenerated Cellulose Hydrogels: Highly Sensitive SERS Detection of Polystyrene Micro/Nanoplastics With Interpretable Deep Learning

Advanced Functional Materials, EarlyView.
A regenerated cellulose (RC) hydrogel‐based SERS substrate integrating a Marangoni‐transferred gold nanoparticle self‐assembled monolayer (Au‐SAM) is fabricated. Reswelling‐induced hotspot formation enhances polystyrene micro/nanoplastics (PS MNPs) detection in complex matrices, providing reproducible, high‐throughput SERS signals across diverse ...

A Simple Model for Estimating the Hydraulic Conductivity of Unsaturated Soil

Applied Sciences
Describing the hydraulic conductivity of unsaturated soil is very important in predicting water transport. Most current models have complex forms and generally need to be calibrated by the measured unsaturated hydraulic conductivity curve. A simple model,

Soil-Water Characteristic Curve Model Based on Particle Size Distribution and Pellicular Water [PDF]

长江科学院院报
Traditional models for predicting soil-water characteristic curve (SWCC) based on particle size distribution curve require segmentation of the curve when calculating water content and often neglect the pellicular water (also known as film water) content ...
