Langmuir . 2024 Nov; 40(46):24387-24396. PMID: 39501882
The shape and stability of a droplet in contact with a solid surface is affected by the chemical composition and topography of the solid, and crucially, by the droplet's size....

Langmuir . 2021 Jun; 37(24):7328-7340. PMID: 34101471
The dynamic effect of an electric field on dielectric liquids is called liquid dielectrophoresis. It is widely used in several industrial and scientific applications, including inkjet printing, microfabrication, and optical...

Edwards A, Ruiz-Gutierrez E, Newton M, McHale G, Wells G, Ledesma-Aguilar R, et al.
Sci Rep . 2021 Apr; 11(1):8120. PMID: 33854150
The breakup of a slender filament of liquid driven by surface tension is a classical fluid dynamics stability problem that is important in many situations where fine droplets are required....

Barrio-Zhang H, Ruiz-Gutierrez E, Armstrong S, McHale G, Wells G, Ledesma-Aguilar R
Langmuir . 2020 Dec; 36(49):15094-15101. PMID: 33258609
Contact-line pinning and dynamic friction are fundamental forces that oppose the motion of droplets on solid surfaces. Everyday experience suggests that if a solid surface offers low contact-line pinning, it...

Ruiz-Gutierrez E, Ledesma-Aguilar R
J Phys Condens Matter . 2020 Jan; 32(21):214007. PMID: 31989993
We study the relaxation towards equilibrium of a liquid barrel-a partially wetting droplet in a wedge geometry-using a diffuse-interface approach. We formulate a hydrodynamic model of the motion of the...

Baratian D, Ruiz-Gutierrez E, Mugele F, Ledesma-Aguilar R
Soft Matter . 2019 Aug; 15(35):7063-7070. PMID: 31441482
The motion of confined droplets in immiscible liquid-liquid systems strongly depends on the intrinsic relative wettability of the liquids on the confining solid material and on the typical speed, which...

Ruiz-Gutierrez E, Ledesma-Aguilar R
Langmuir . 2019 Mar; 35(14):4849-4859. PMID: 30869524
When a voltage difference is applied between a conducting liquid and a conducting (solid) electrode, the liquid is observed to spread on the solid. This phenomenon, generally referred to as...

Wells G, Ruiz-Gutierrez E, Le Lirzin Y, Nourry A, Orme B, Pradas M, et al.
Nat Commun . 2018 Apr; 9(1):1380. PMID: 29643382
Droplet evaporation on solid surfaces is important in many applications including printing, micro-patterning and cooling. While seemingly simple, the configuration of evaporating droplets on solids is difficult to predict and...

Ruiz-Gutierrez E, Guan J, Xu B, McHale G, Wells G, Ledesma-Aguilar R
Phys Rev Lett . 2017 Jun; 118(21):218003. PMID: 28598678
We demonstrate the continuous translational invariance of the energy of a capillary surface in contact with reconfigurable solid boundaries. We present a theoretical approach to find the energy-invariant equilibria of...
