Titration of a series of C(18) fatty acids yields pK(a) values that decrease with an increasing degree of unsaturation in the fatty acid chain. The pK(a) values of stearic, elaidic, oleic, linoleic, and linolenic acids were studied and compared to values of area per molecule in a spread monolayer of these acids. The decrease in pK(a) was found to relate to(More)
domain (head) of the surfactant influence the cmc. The two Relationships between the molecular structure and the critical contributions are counteracting, with a lower cmc for a larger micelle concentration (cmc) of anionic surfactants were investi-hydrophobic domain and a higher cmc for a larger hydro-gated using a quantitative structure–property(More)
Magnetic nanoparticles of barium ferrite (BaFe 12 O 19) have been synthesized using a microemulsion mediated process. The aqueous cores of water-in-oil microemulsions were used as constrained microreactors for the precipitation of precursor carbonate and hydroxide particles. These precursors were then calcined at 925°C for 12 hours, during which time they(More)
Glaucoma is a second leading cause of blindness globally after cataract, which is managed through eye drops, which are highly inefficient due to a low bioavailability of less than 1-5%. Frequent administration of eye drops leads to incompliance in patients, so there is a great need for medical device such as contact lenses to treat glaucoma. The objective(More)
