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.

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.

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.

Super-hydrophobic and super-wetting surfaces: analytical potential? [PDF]
, 2004 Roughening or texturing surfaces provides super-liquid repellent or film forming properties without alteration of the surface chemistry. These surfaces are easy to produce, can amplify wetting properties and can be either "sticky" or "slippy" to liquids.

Quantitative NMR monitoring of liquid ingress into repellent heterogeneous layered fabrics [PDF]
, 2008 Fabrics which are water repellent and repellent to other liquids are often constructed using multiple layers of material. Such a construction is preferable to a single layer of a liquid-repellent textile because, under the action of an applied pressure ...

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 ...

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

Pressure generated by partially water-repellent flat thrust bearing with weak water-repellent part
Nihon Kikai Gakkai ronbunshu, 2021 The generation state of the pressure for partial water-repellent (slip) type flat thrust bearings with high/low slip parts was examined with experiments and infinite width bearing approximation.

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013 In this study, a flat thrust bearing is developed by active exploiting the slip flow generated on a water-repellent surface. In order to produce a load, this bearing has a structure that generates a pressure flow by using the discontinuity of shear flow ...
