Hydrodynamics Of Drops And Particles Driven By Marangoni And Diffusiophoretic Forces
… hydrodynamics of particles and drops driven by forces generated by an asymmetrical physical and chemical surrounding environment. In the first part, a novel colloidal motor design driven by surface tension forces is proposed, utilizing an active Janus particle encapsulated in an immiscible …

Tip-based nanomanufacturing and metrology of heterogeneous nanostructures
… and heating times. It is found that thermal Marangoni forces and non-equilibrium wetting govern the nanometer-scale polymer flow, and that the polymer viscosity governs the mass flow rate. Polymer nanostructures are then characterized by AFM-IR. Nanostructures of polyethylene, polystyrene, …

Instabilities of volatile films and drops
… in both liquid and solid, (thermocapillary) Marangoni effect, vapor recoil, disjoining pressure, and gravity. The crucial ingredient in this problem is the evaporation model, since it influences both the motion of the drop contact line, and the temperature profiles along the liquid-solid and …

Nonlinear interfacial stability of core-annular film flows in the presence of surfactants
… The surfactant modifies the flow by inducing Marangoni forces along the interface which in turn modify both the velocities and interfacial amplitudes. There are two parameters present in the nonlinear system, the length of the system and a surface Peclet number which measures the diffusion of …

Engineered interfaces controlling the nucleation and flowability of complex fluids
… engineered chemistry and textures, with driving forces ranging from electrical, magnetic, gravitational, as well as Marangoni forces. Engineered surfaces were also shown to control and improve processes that involve nucleation phenomena such as boiling, condensation, and water collection from …

Vermeidungsstrategien fluiddynamischer Effekte beim Einsatz von Schnellerwärmungstechnologien in der Warmumformung
… Es können insbesondere die temperatursensitive Marangonikraft als auch die magnethydrodynamische Wirkung der Lorentzkraft bei einer induktiven Erwärmung als Haupttriebkräfte identifiziert werden, die sich aufgrund identischer Kraftvektorrichtungen überlagern und verstärken. Es hat sich gezeigt, …
