A Simple Device to Measure Soil Water Retention Curve

, 2019
The soil water retention curve is very critical in the assessment of unsaturated soil behavior. In the past, with the help of the axis translation technique, the pressure plate method was usually used to measure the soil water retention curve.

Analysis of water vapor adsorption in soils by means of a lysimeter and numerical modeling

Vadose Zone Journal, 2020
Daily temperature oscillations can cause adsorption (and desorption) of atmospheric water vapor by soils. The resulting daily fluctuations in the amount of liquid water in the soil can be measured by high‐precision weighing lysimeters.

Temperature Dependence of Water Retention Curves for Wettable and Water-Repellent Soils

Soil Science Society of America Journal, 2002
The capillary pressure (ψ) in unsaturated porous media is known to be a function of temperature ( T ). Temperature affects the surface tension (σ) of the pore water, but possibly also the angle of contact (γ).

Study on water retention characteristics of coastal soils in Northern Zhejiang Province

浙江大学学报. 农业与生命科学版, 2001
The water retention characteristics of coastal soils in Zhejiang Province were studied. Results showed that water retention curves of coastal soils were a typical double-curve and the best modal to characterize the relationship between soil water content

Determination of soil-water retention curve: an artificial intelligence-based approach [PDF]

E3S Web of Conferences, 2020
Soil Water Retention Curve (SWRC) is a fundamental relationship in unsaturated soil mechanics, knowledge of which is essential for determining major mechanical and hydraulic properties of unsaturated soils. There are several empirical, semi-empirical and

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Average Soil Water Retention Curves Measured by Neutron Radiography

Soil Science Society of America Journal, 2012
Water retention curves are essential for understanding the hydrologic behavior of partially saturated porous media and modeling flow and transport processes within the vadose zone. We directly measured the main drying and wetting branches of the average water retention function obtained using two-dimensional neutron radiography. Flint sand columns were

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
