A new hydraulic conductivity model of frozen soil considering the hysteresis effect based on fractal theory

open access: yesGeoderma
The hydraulic conductivity of frozen soil is crucial for predicting water migration and frozen heave. Many models have been proposed to estimate the hydraulic conductivity, which involves factors such as unfrozen water content, specific surface area ...

Evolution of OLED Lamination Technology With Development of Display Form Factors

open access: yesAdvanced Materials Technologies, EarlyView.
This review evaluates the evolution of organic light‐emitting diode (OLED) lamination technologies alongside advancing display form factors. It contrasts optically clear adhesives and resins, highlighting uniformity control for rigid screens, bubble‐free optimization for bended architectures, and visible‐light curing for foldable layers.

The effect of long-term irrigation with municipal treated wastewater on the saturated hydraulic conductivity of a silt loam soil and its estimation- a case study

open access: yesعلوم آب و خاک, 2017
Treated wastewater may influence soil structure, porosity and as a consequence, soil saturated hydraulic conductivity. This study aims to assess the effect of wastewater on saturated hydraulic conductivity; and to determine the suitable soil solids ...

Compacted sand-bentonite mixtures for hydraulic containment liners [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2005
Sand is a pervious material in nature. Mixing sand with appropriate bentonite contents yields sandbentonite mixtures having low hydraulic conductivity that can be used as hydraulic containment liners.

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

open access: yesAdvanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Analytical expressions for macrodispersion in three-dimensional Sub-Gaussian hydraulic conductivity fields

open access: yes, 2021
Subsurface flow and transport settings are typically characterized by spatial variability of the underlying hydro-geological attributes (e.g., permeability and porosity) and a high degree of uncertainty associated with data and model parameter estimates.

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Impact of spatially varying hydraulic conductivities on tumor interstitial fluid pressure distribution

open access: yesInformatics in Medicine Unlocked, 2019
This work deals with numerical computation of the interstitial fluid pressure distribution for various synthetic tumor configurations in two spatial dimensions. In order to attend a reasonable degree of realism, we also consider asymmetric configurations
