The Applicability of a Drop Penetration Method to Measure Contact Angles on TiO₂ and ZnO Nanoparticles

Nanomaterials, 2020
In this study, six solvents (water, diiodomethane, bromonaphthalene, formamide, ethanol and ethylene glycol) were examined for three nanoparticle substrates, zinc oxide and titanium dioxide (21 nm and 100 nm), with the goal of assessing the suitability ...

Effects of hydrophobicity on splash erosion of model soil particles by a single water drop impact [PDF]

, 2013
Raindrop impact can be a major contributor to particle mobilization for soils and other granular materials. In previous work, water repellent soils, comprised of hydrophobic particles, have been shown to exhibit greater splash erosion losses under ...

Transitions of water-drop impact behaviour on hydrophobic and hydrophilic particles [PDF]

, 2013
Extreme soil water repellency can have substantial implications for soil hydrology, plant growth and erosion, including enhanced splash erosion caused by raindrop impact.

Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]

, 2011
The wettability of soil is of great importance for plants and soil biota, and in determining the risk for preferential flow, surface runoff, flooding,and soil erosion. The molarity of ethanol droplet (MED) test is widely used for quantifying the severity

Water-repellent soil and its relationship to granularity, surface roughness and hydrophobicity: a materials science view [PDF]

, 2005
Considerable soil water repellency has been observed at a wide range of locations worldwide. The soil exhibiting water repellency is found within the upper part of the soil profile.

Small-scale contact angle mapping on undisturbed soil surfaces

Journal of Hydrology and Hydromechanics, 2013
Research of the last years pointed out that most soils are neither completely hydrophilic nor hydrophobic, but exhibit a subcritical level of water repellency (i.e. contact angle, CA > 0° and < 90°).

Extent and persistence of soil water repellency induced by pines in different geographic regions

Journal of Hydrology and Hydromechanics, 2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions.

Implications of ideas on super-hydrophobicity for water repellent soil [PDF]

, 2007
Water repellence is an important factor in soil erosion due to its role in inhibiting the re-establishinent of vegetation after fire and due to its enhancement of run-off.

Initial water repellency affected organic matter depletion rates of manure amended soils in Sri Lanka

Journal of Hydrology and Hydromechanics, 2014
The wetting rate of soil is a measure of water repellency, which is a property of soils that prevents water from wetting or penetrating into dry soil.
