How Safe Are Organic Polymers in Water Treatment
An anionic organic polymer commonly used in France was analyzed by several methods. It was found to be generally acceptable for drinking water standards in the United States and France. But the by‐products and impurities that were detected require more research to determine their potential health effects and demonstrate the need for adequate

Zeta Potential of Polyelectrolytes
Polyelectrolytes are polymer chains with an electrolyte group on every repeat unit. These polymers are charged when dissolved in a polar solvent due to dissociation of small counter ions that leave behind a charged macro ion. In addition to synthetic polymers, polyeletrolytes include biologically important molecules such as polypeptides and DNA.

Ion Transport and the True Transference Number
Nonaqueous polyelectrolyte solutions have been recently proposed as high Li+ transference number electrolytes for lithium ion batteries. However, the atomistic phenomena governing ion diffusion and migration in polyelectrolytes are poorly understood, particularly in nonaqueous solvents.
