Coalescence of Polymer Droplets Moving on a Surface with Stiffness Gradient
Divyansh Tripathi, Vimal Kishore, Panagiotis E. Theodorakis +1
Here, we study the coalescence of two droplets that are moving in the same direction on a soft surface; the motion of the droplets is caused by a gradient in the surface stiffness.…
Directed droplet motion -- Its versatile nature and anticipated applications
Panagiotis E. Theodorakis, Andrey Milchev
Applications such as digital microfluidics and bio-diagnostics rely on droplet locomotion. A prominent example of such motion is durotaxis, a phenomenon that requires a stiffness g…
Coarse-Grained Model of the Sodium Dodecyl Sulfate Anionic Surfactant Based on the MDPD--Martini Force Field
LuÃs H. Carnevale, Gabriela Niechwiadowicz, Panagiotis E. Theodorakis
The sodium dodecyl sulfate (SDS) surfactant is widely used in various applications, such as household products (e.g., shampoos, toothpaste, detergents, and cleaning products) and f…
Phase Transitions of Oscillating Droplets on Horizontally Vibrating Substrates
King L. Ng, LuÃs H. Carnevale, MichaÅ Klamka +3
Droplet deformations caused by substrate vibrations are ubiquitous in nature and highly relevant for applications such as microreactors and single-cell sorting. The vibrations can…
Collision of surfactant-laden droplets: insights from molecular dynamics simulation
Soheil Arbabi, Piotr Deuar, Rachid Bennacer +2
We study the collision dynamics of surfactant-laden droplets and compare it with that of pure water droplets, with a focus on the bridge growth rate, energy balance, and disk dynam…
Many-Body Dissipative Particle Dynamics Simulations of Lipid Bilayers with the MDPD-MARTINI Force-Field
Natalia Kramarz, LuÃs H. Carnevale, Panagiotis E. Theodorakis
Many-body dissipative particle dynamics (MDPD) offers a significant speed-up in the simulation of various systems, including soft matter, in comparison with molecular dynamics (MD)…
