Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering
Advanced Functional Materials, EarlyView.This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker
Advanced Functional Materials, EarlyView.Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.

DISPERSION IN HIGH-POROSITY POROUS MEDIUM
Journal of Porous Media, 2023In this study, the behavior of flow and transport through a high-porosity porous medium is investigated numerically. Steady-state, 2D Navier-Stokes and transient advection-diffusion equations are solved numerically to simulate water flow and tracer transport in an artificial porous medium.

SIAM Journal on Mathematical Analysis, 1988
A boundary value problem and the Cauchy problem for a quasilinear time- dependent system of partial differential equations is studied. The model describes combustion in a porous medium. An interesting feature (expressed by the Heaviside function in the reaction term) is the presence of a mechanism that switches off the reaction under certain ...

Porous Medium Equation with Absorption
SIAM Journal on Mathematical Analysis, 1998The paper studies the approach to the steady state for the porous medium equation with absorption in a bounded domain in \(\mathbb{R}^N\) with time-independent Dirichlet conditions. Special attention is given to the case where the solution of the steady state vanishes in a interior region (known as a dead core).

POROUS MEDIUM MAGNETOHYDRODYNAMICS
Acta Mathematica Scientia, 1982Abstract here we established the mathematical model of dynamics of porous solid medium saturated with compressible magneto-fluid, directly coupled the stress, flow and electromagnetic fields, studied their interactions and propagation regularity of waves and proved that there exist various P and S waves and also their mixture, which, generally ...

Phenomena of transport in porous media are encountered in many engineering disciplines. Civil engineering deals, for example, with the flow of water in aquifers, the movement of moisture through and under engineering structures, transport of pollutants in aquifers and the propagation of stresses under foundations of structures. Agricultural engineering

Helical locomotion in a porous medium
Physical Review E, 2020Microorganisms and artificial microswimmers often need to swim through environments that are more complex than purely viscous liquids in their natural habitats or operational environments, such as gel-like mucus, wet soil, and aquifers. The question of how the properties of these complex environments affect locomotion has attracted considerable recent ...

The extended Biot model for sands and silts is repurposed to include mud, but modifications are needed. The boundary between pore water and skeletal frame needs to be redefined because a significant fraction of the pore fluid is adsorbed onto the solid frame by electrostatic forces, and a proportion of the solid particles may be suspended in the pore ...

Drag forces of porous-medium acoustics
Physical Review B, 1993The drag forces controlling the amount of relative flow induced in a fluid-saturated porous material by a mechanical wave are modeled here from first principles. Specifically, analytical expressions for the drag are derived for material models that possess variable-width pores; i.e., pores that have widths that vary with distance along their axis.
