Water permeation through stratum corneum lipid bilayers from atomistic simulations
Chinmay Das, Peter D. Olmsted, Massimo G. Noro
Stratum corneum, the outermost layer of skin, consists of keratin filled rigid non-viable corneocyte cells surrounded by multilayers of lipids. The lipid layer is responsible for t…
Scaling theory for diffusion limited cluster aggregation in a porous medium
Patrick B. Warren
A scaling theory is developed for diffusion-limited cluster aggregation in a porous medium, where the primary particles and clusters stick irreversibly to the walls of the pore spa…
The wall shear rate distribution for flow in random sphere packings
Patrick B. Warren, Frantisek Stepanek
The wall shear rate distribution P(gamma) is investigated for pressure-driven Stokes flow through random arrangements of spheres at packing fractions 0.1 <= phi <= 0.64. For dense…
Flory-Huggins theory for the solubility of heterogeneously-modified polymers
Patrick B. Warren
Many water soluble polymers are chemically modified versions of insoluble base materials such as cellulose. A Flory-Huggins model is solved to determine the effects of heterogeneit…
