Coupled mutual diffusion in aqueous paracetamol + sodium hydroxide solutions
Ternary mutual diffusion coefficients (Dik) measured by the Taylor dispersion method are reported for aqueous paracetamol + NaOH solutions at 25.00 °C and concentrations up to 0.050 mol dm−3. The coupled diffusion of parace...

Study of diffusion in two-phase systems with fix and moving interphase boundaries in the presence of a diffusion source
of the element, whose diffusion is investigated, is created in the proximity of the interphase boundary before the diffusion heating itself. This phenomenon must be included in the diffusion equation solution. In ...

Asymptotic behavior of solutions to the semidiscrete diffusion equation
We study the asymptotic behavior of bounded solutions to the one-dimensional diffusion (heat) equation with discrete space and continuous time. We show that a bounded solution approaches the average of the initial values if...

On the number of stationary patterns in reaction-diffusion systems
We study systems of two nonlinear reaction-diffusion partial differential equations undergoing diffusion driven instability. Such systems may have spatially inhomogeneous stationary solutions called Turing patterns. These <...
