Measuring material properties of tectorial membranes from normal and genetically modified mice
… The effect of the mutation was to decrease the fixed charge concentration, which was found to be the primary determinant of the bulk modulus. However, the shear modulus was not affected. Collla2 is one of the genes that encodes for type XI collagen. Mutation in this gene causes no significant …

Structural Studies of the Corneal Stroma
… contains glycosaminoglycans which are negatively charged at physiological pH. The organisation of the collagen fibrils and their relationship to the glycosaminoglycans are important when considering both the transparency and the ability to swell of the fresh tissue and the reason for the loss in …

Synthesis and Characterization of Linear and Crosslinked Mono-Sulfonated Poly(arylene ether sulfone)s for Reverse Osmosis Applications
… bind with the anionic sulfonate groups to cause charge screening, and this can lead to too much salt passage for the membranes to be competitive with interfacially produced polyamides. Sulfonate fixed charge concentration must be high enough for sufficient membrane water uptake to obtain high …

Synthesis and Characterization of Novel Pol(arylene ethers) for Gas Separation and Water Desalination Membranes
… (PPO) of different molecular weights in a fixed ratio (66/34 wt/wt) and in various ratios of a 22000 g/mol PPO. All the blends were UV crosslinked to minimize plasticization by condensable gases and analyzed for gel fractions, whereas, only the 22,000 g/mol blends were tested for transport …
