Broadband molecular dynamics simulation of fluid inertial effects in confined Brownian motion
Quentin Thomas, Clara Mefo Sop, Maxime Lavaud +3
Hydrodynamic memory governs Brownian motion over a broad range of timescales, from acoustic wave propagation at short times to diffusive relaxation at long times. While confinement…
Quantitative measurement of fluid inertial effects in confined Brownian motion
Quentin Ferreira, Pablo Palacios-Alonso, Harshit Joshi +3
The hydrodynamic response of Brownian particles in liquids is fundamentally altered by inertial forces arising from unsteady momentum transport in the surrounding fluid. These forc…
Nanostructure of PEGDA-PEG hydrogel membranes and how it controls their permeability
Sixtine de Chateauneuf-Randon, Malak Alaa Eddine, Bruno Bresson +7
The spacial heterogeneity of hydrogels composed of PEGDA and added polymer chains is expected to play a crucial role on their transport properties which can be exploited in filtrat…
Linear poroelastic response of thin permeable gel films
Caroline Kopecz-Muller, Joshua D Mcgraw, Thomas Salez
When a hydrophilic and deformable porous material is immersed in a bath, it may absorb the solvent and expand by several times its volume, thus forming a highly soft and porous hyd…
Polymeric Solvents Control Swelling-Induced Surface Creasing
Zechao Jiang, Zhaoyu Ding, Shaohua Yang +7
Surface creasing in swelling polymer gels is commonly attributed to compressive strain or interlayer mismatch, yet its general control remains unclear. Here we show that solvent po…
Taylor dispersion in a soft tube
Aditya Jha, Masoodah Gunny, Joshua D Mcgraw +2
Diffusion of a solute along a tube is enhanced by hydrodynamic flow, a phenomenon known as Taylor dispersion. In microfluidic applications, the compliance of the tube boundaries mo…
Electrohydrodynamic lubrication theory for an immersed cylinder moving near wall
Anirban Chatterjee, Yacine Amarouchene, Thomas Salez
The free motion of charged colloids within ionic solutions and in the vicinity of charged boundaries, is a phenomenon that occurs in various natural, biological and industrial sett…
Suppressed Rupture of Thin Metal Films via van der Waals Epitaxy
Wenxiang Wang, Jiaxing Wang, Guotong Wang +9
Ultrathin metal films exhibit liquid-like instabilities, rupturing via surface diffusion far below their melting points. This behavior constrains thermal budgets for advanced integ…
A label-free method to quantify early-stage amyloid aggregation via intrinsic phenylalanine fluorescence
Gaëlle Audéoud, Louis Moine, Laura Bonnecaze +5
The aggregation of amyloid-forming peptides is a dynamic, complex process that underlies their diverse biological activities, from physiological functions to disease-associated dys…
