Abstract: Disclosed herein is a method for dissolving ion exchange membranes to provide dissolved polymers, particularly at low temperatures and/or pressures, that can be recast to regenerate ion exchange membranes exhibiting reduced defects compared to the initial ion exchange membrane. In some aspects of the disclosure, the polymer exchange membranes include a perfluorosulfonic acid polymer. In some aspects of the disclosure, the method involves dissolving the membranes in one or more aprotic solvents, particularly at temperatures below 80° C.

Abstract: Aquatic tracking makes use of acoustics, rather than other signals that do not travel as well in water. Tracking devices are used to monitor species of fish and other aquatic animals to monitor how their populations and movements are in nature, and how or whether those populations and movements are affected by, for example, hydroelectric dams and other manmade structures and phenomena. Often, the trackers inserted in aquatic animals adversely affect the animals and can lead to mortality or changed behaviors. New solutions that decrease the size and weight of such tracking devices are disclosed herein, enabling better tracking of aquatic animals that is less likely to cause adverse effects to those populations.
