Interfacial aggregation of self-propelled Janus colloids in sessile droplets
Maziyar Jalaal, Borge ten Hagen, Hai le The +3
Living microorganisms in confined systems typically experience an affinity to populate boundaries. The reason for such affinity to interfaces can be a combination of their directed…
Evaporation of binary liquids from a capillary tube
Lijun Thayyil Raju, Christian Diddens, Javier Rodríguez-Rodríguez +4
Evaporation of multi-component liquid mixtures in confined geometries, such as capillaries, is crucial in applications such as microfluidics, two-phase cooling devices, and inkjet…
Evaporation-driven liquid flow in sessile droplets
Hanneke Gelderblom, Christian Diddens, Alvaro Marin
The evaporation of a sessile droplet spontaneously induces an internal capillary liquid flow. The surface-tension driven minimisation of surface area and/or surface-tension differe…
Evaporation of a sessile colloidal water-glycerol droplet: Marangoni ring formation
Lijun Thayyil Raju, Christian Diddens, Yaxing Li +4
The transport and aggregation of particles in suspensions is an important process in many physicochemical and industrial processes. In this work, we study the transport of particle…
Physiochemical hydrodynamics of the phase segregation in an evaporating binary microdroplet
Yaxing Li, Pengyu Lv, Christian Diddens +1
Phase segregation triggered by selective evaporation can emerge in multicomponent systems, leading to complex physiochemical hydrodynamics. Recently, Li et al. (Phys. Rev. Lett., v…
Sessile drop evaporation in a gap -- crossover between diffusion-limited and phase transition-limited regime
S. Hartmann, C. Diddens, M. Jalaal +1
We consider the time evolution of a sessile drop of volatile partially wetting liquid on a rigid solid substrate. Thereby, the drop evaporates under strong confinement, namely, it…
Selective evaporation at the nozzle exit in piezoacoustic inkjet printing
Maaike Rump, Uddalok Sen, Roger Jeurissen +5
In practical applications of inkjet printing the nozzles in a printhead have intermittent idle periods, during which ink can evaporate from the nozzle exit. Inks are usually multic…
Droplet dissolution driven by emerging thermal gradients and Marangoni flow
Binglin Zeng, Yuliang Wang, Christian Diddens +2
The lifetime of an isothermal and purely diffusively dissolving droplet in a host liquid scales as with its initial radius [Langmuir, Phys. Rev. 12, 368 (19…
Oscillatory droplet dissolution from competing Marangoni and gravitational flows
Ricardo Arturo Lopez de la Cruz, Christian Diddens, Xuehua Zhang +1
The dissolution or growth of a droplet in a host liquid is an important part for processes like chemical extraction, chromatography or emulsification. In this work we look at the d…
The asymmetric coalescence of two droplets with different surface tensions is caused by capillary waves
Michiel A. Hack, Patrick Vondeling, Menno Cornelissen +4
When two droplets with different surface tensions collide, the shape evolution of the merging droplets is asymmetric. Using experimental and numerical techniques, we reveal that th…
