]]>Particle-stabilized emulsions are commonly used in various industrial applications. These emulsions can present in different forms, such as Pickering emulsions or bijels, which can be distinguished by their different topologies and rheology. We numerically investigate the effect of the volume fracti...

We consider systems where the particle motion is restricted by the harmonic external trapping potential and the container edge wall. In ...

We find that solidification fronts can advance via two different mechanisms, depending on the depth of the quench. For shallow quenc...

The liquid-crystal orientation is rigorously solved via a tensorial formulation of the Landau–de Gennes theory and the optical transmission properties of the gratings are i...

In this work, small-angle neutron scattering experiments are performed to reveal the rol...

Thus, such data are usually a mixture of useful information and useless coherent noise. The latter masks the relevant geologic information ...

A powerful numerical scheme is developed which provides us with the Floquet modes and thus enables a stroboscopic propagation of arbitrary initial states. A detailed symmetry analysis represents the cornerstone for an...

Based on the speed-gradient method, our scheme adapts the topology of a network such that the target state is realized. It is robust towards different initial conditions as well a...

The paradox that we identify, originally perceived in classical networks, shows that the addition of more capacity to the network can suppress the current flow in the universal re...

When plant roots are added into the soil, water transfer between the soil and the outside environment is even more complicated. Indeed, plants provide an additional process of water transfer. Water is pumped by the ...
