Abstract: The anion exchange membranes exhibit enhanced chemical stability and ion conductivity when compared with traditional styrene-based alkaline anion exchange membranes. A copolymer backbone is polymerized from a reaction medium that includes a diphenylalkylene and an alkadiene. The copolymer includes a plurality of pendant phenyl groups. The diphenyl groups on the polymer backbone are functionalized with one or more haloalkylated precursor substrates. The terminal halide from the precursor substrate can then be substituted with a desired ionic group. The diphenylethylene-based alkaline anion exchange membranes lack the α-hydrogens sharing tertiary carbons with phenyl groups from polystyrene or styrene-based precursor polymers, resulting in higher chemical stability. The ionic groups are also apart from each other by about 3 to 6 carbons in the polymer backbone, enhancing ion conductivity. These membrane are advantageous for use in fuel cells, electrolyzers employing hydrogen, ion separations, etc.

Abstract: The present invention relates to a process for the purification of an acidic human milk oligosaccharide (HMO) from a fermentation broth using ion exchange methods. This process allows for a reduction of the number and/or extent of desalting operations, such as electrodialysis. It is even possible to refrain from such operations.

Abstract: A process for boron removal from feed water. The process includes the steps of introducing a stream of feed water with sodium borate salt or calcium borate salt therein to an ion exchange vessel containing boron-selective resin modified with potassium sulfate or sodium sulfate. The feed water is reacted with the boron-selective resin modified with sodium sulfate or potassium sulfate. The ion exchange resin in the ion exchange vessel is periodically regenerated.

Abstract: A major challenge in the development of anion exchange membranes for fuel cells is the design and synthesis of highly stable (chemically and mechanically) and conducting membranes. Membranes that can endure highly alkaline environments while rapidly transporting hydroxides are desired. A design for using cross-linked polymer membranes is disclosed to produce ionic highways along charge delocalized pyrazolium and homoconjugated triptycenes. The ionic highway membranes show improved performance in key parameters. Specifically, a conductivity of 111.6 mS cm−1 at 80° C. was obtained with a low 7.9% water uptake and 0.91 mmol g−1 ion exchange capacity. In contrast to existing materials, these systems have higher conductivities at reduced hydration and ionic exchange capacities, emphasizing the role of the highway. The membranes retain more than 75% of initial conductivity after 30 days of alkaline stability test. This effective water management through ionic highways is confirmed by density functional theory and Monte Carlo studies. A single cell with platinum group metal catalysts at 80° C. showed a high peak density of 0.73 W cm−2 (0.45 W cm−2 from silver-based cathode) and stable performance during 400 h tests.
