Add to ORKGToday,the focus of physical scientists is shifting to biology more than ever before. Because there is no biological tissue that is not a porous medium, the porous media community should be very alert to this shift of attention. The impact that porous media mechanics had on geosciences in the past centuries, may very well be reiterated in the field of biology - in an amplified form. The characteristic pore size in biological applications is close to the molecular level and hence below the Debye-Hueckel scale. Not only pressure gradients and concentration gradients, but electrical gradients as well are intimately linked to fluid flow, ion flow and deformation. To give a feeling for the subject, applications are covered in this presentation : ...
