J Colloid Interface Sci
. 2021 Nov;
608(Pt 3):2330-2338.
PMID: 34774316
Hypothesis: Emerging energy-related technologies deal with multiscale hierarchical structures, intricate surface morphology, non-axisymmetric interfaces, and complex contact lines where wetting is difficult to quantify with classical methods. We hypothesise that...

Phys Rev E
. 2021 Oct;
104(3-2):035106.
PMID: 34654200
We develop nonequilibrium theory by using averages in time and space as a generalized way to upscale thermodynamics in nonergodic systems. The approach offers a classical perspective on the energy...

Sun C, McClure J, Mostaghimi P, Herring A, Meisenheimer D, Wildenschild D, et al.
J Colloid Interface Sci
. 2020 Jun;
578:106-115.
PMID: 32521350
Hypothesis: Understanding wetting behavior is of great importance for natural systems and technological applications. The traditional concept of contact angle, a purely geometrical measure related to curvature, is often used...

J Colloid Interface Sci
. 2019 Dec;
561:173-180.
PMID: 31812863
Hypothesis: Wetting phenomena play a key role in flows through porous media. Relative permeability and capillary pressure-saturation functions show a high sensitivity to wettability, which has different definitions at the...

Sci Rep
. 2018 Oct;
8(1):15518.
PMID: 30341346
Fluid flow in porous rocks is commonly capillary driven and thus, dependent on the surface characteristics of rock grains and in particular the connectivity of corners and crevices in which...
