Organic Solvent Nanofiltration Membranes to Separate and Purify Fatty Acids

Bowden N.B., University of Iowa, US

Separations in the chemical industry account for 40-70% of the total operating costs because most separations require high amounts of energy or the use of solvents that must be removed and recycled. Membranes are extensively [...]

New biodegradable polymers based on previously unknown functional groups for drug and gene delivery

Yoo J., Graf T.A., Kuruvilla D.J., D’Mello S.R., Salem A.K., Bowden N.B., University of Iowa, US

We developed the synthesis of three new sets of polymers based on bonds between sulfur and nitrogen for applications in drug and gene delivery. These polymers were designed to slowly degrade in water at pH [...]

Separation of mixtures of fatty acids into individual components using a nanoporous membrane

Gupta A., Bowden N.B., University of Iowa, US

We recently developed the first method to separate fatty acids derived from vegetable oils using nanoporous membranes based on polydicyclopentadiene. Fatty acids were too small and too similar in size to be separated from one [...]
