Convection in nanofluids with a particle-concentration-dependent thermal conductivity.
TLDR
Thermal convection in nanofluids is investigated by means of a continuum model for binary-fluid mixtures, with a thermal conductivity depending on the local concentration of colloidal particles, and it is bounded by two codimension-2 bifurcations.

Stripe-hexagon competition in forced pattern-forming systems with broken up-down symmetry.
TLDR
The response of two-dimensional pattern-forming systems with a broken up-down symmetry to spatially resonant forcing is investigated and their range of existence, stability, and coexistence is determined.

Convection in colloidal suspensions with particle-concentration-dependent viscosity
Abstract.The onset of thermal convection in a horizontal layer of a colloidal suspension is investigated in terms of a continuum model for binary-fluid mixtures where the viscosity depends on the…

TLDR
Transmembrane ion flow through channel proteins undergoing density fluctuations may cause lateral gradients of the electrical potential across the membrane giving rise to electrophoresis of charged channels, and periodic modulations of the ion channel density are preferred in a large range of parameters.

Effects of a temperature-dependent viscosity on thermal convection in binary mixtures.
TLDR
In binary mixtures as a function of a positive separation ratio ψ and beyond a certain viscosity contrast, a discontinuous transition between two stationary convection modes having different wavelengths is found.

Hexagonal, square and stripe patterns of the ion channel density in biomembranes
TLDR
In a two-dimensional extended membrane hexagonal modulations of the ion channel density are preferred in a large range of parameters, whereby the wave number decreases with the kinetic rate of the binding-release reaction.
