Viruses at solid-water interfaces: A systematic assessment of interactions driving adsorption

Tamar Kohn, Meret Aeppli, Anne Thérèse Sigstam, Antonius Magdi Hakeem Armanious, Dominik Refardt

Adsorption to solid-water interfaces is a major process governing the fate of waterborne viruses in natural and engineered systems. The relative contributions of different interaction forces to adsorption and their dependence on the physicochemical propert ...

Characterization of the velocity fields generated by flow initialization in the CFD simulation of multiphase flows

John Richard Thome, Mirco Magnini

Recent improvements in numerical algorithms for Eulerian-based CFD simulations of multiphase flows can now recover the exact balance between the pressure and surface tension terms within the momentum equation. This has led to the minimization of the so cal ...

Two-phase flow effects on the CO2 injection pressure evolution and implications for the caprock geomechanical stability

Victor Vilarrasa Riano

Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a two-phase flow, being CO2 the non-wetting phase. ...

Influence of the wetting angle on capillary forces in pressure infiltration

Andreas Mortensen, Ludger Weber, Alain Léger

This work probes the influence of wetting on pressure infiltration. Pressure/saturation curves for the infiltration of packed F1000 angular alumina particle preforms by liquid Cu-Al and Sn-Al alloys are measured using an instrumented high-temperature press ...

Investigation of liquid pinning on surface nanoscale topography

Capillarity assisted particle assembly (CAPA), is a powerful technique which is gaining in importance. Indeed the application possibilities are vast but, due to its relatively early research stage, the optimal and generic assembly parameters have yet to be ...

Mechanism of the Cassie-Wenzel transition via the atomistic and continuum string methods

Simone Meloni

The string method is a general and flexible strategy to compute the most probable transition path for an activated process (rare event). We apply here the atomistic string method in the density field to the Cassie-Wenzel transition, a central problem in th ...

Capillarity in pressure infiltration: influence of percolation and wetting angle

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Composite materials are often produced by pressure-infiltration of a liquid matrix into a preform of packed solid fibers or particles. Capillary forces that intervene in this process are quantified by measuring saturation curves, which are plots of the fra ...

Modeling capillary forces for large displacements

Massimo Mastrangeli, Pierre Lambert

Originally applied to the accurate, passive positioning of submillimetric devices, recent works proved capillary self-alignment as effective also for larger components and relatively large initial offsets. In this paper, we describe an analytic quasi-stati ...

Unraveling the Salvinia Paradox: Design Principles for Submerged Superhydrophobicity

Simone Meloni

The complex structure of the Salvinia molesta is investigated via rare event molecular dynamics simulations. Results show that a hydrophilic/hydrophobic patterning together with a re-entrant geometry control the free energy barriers for bubble nucleation a ...

Influence of temperature and wetting angle on capillarity in pressure infiltration

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Capillary forces in the pressure infiltration process can be quantified by measuring saturation curves; these are plots of the fraction pore space filled with the liquid infiltrant versus the pressure difference between the liquid and the atmosphere initia ...
