Pore-filled nanofiltration membranes based on poly(2-acrylamido-2-methylpropanesulfonic acid) gels

Gel-filled hollow fiber membranes for water softening

“…Unlike the earlier work carried out with flat sheet membranes [31], the measured mass gains are generally lower than those calculated on the basis of the fiber pore volumes and filling solution concentrations, Table 2. The largest discrepancy is found with the large fiber where only half of the expected mass gain was observed.…”

Mechanical properties of single alginate microspheres determined by microcompression and finite element modelling

“…The hydraulic conductivity values used in the modelling were in the range of k = 2.4×10 −10 -1.7×10 −6 m s −1 (Zimmermann et al, 2007;Zhou et al, 2005;White and Deen, 2002;Li et al, 2004) and these were chosen to span the likely range for calcium alginate microspheres. Some values out of this range were also considered to investigate their possible effect.…”

Percolated interface conductivity of sheet-like electrolyte prepared from poly(2-acrylamido-2-methyl-1-propanesulfonic acid)-deposited core–shell particles and effect of core particle size

“…Similarly, the thickness of the PAMPS layer was estimated to be 1.5 nm. The density of PAMPS used in the estimation was 1.74 g cm −3 [21].…”
