more effective ways to purify existing water sources is becoming more important and innovation with purification membranes through polymer chemistry is leading the way. Geoffrey M. Geise of the ...

Researchers have proposed using polymer membranes modified with copper, zinc, and chromium metal ions for water purification. These polymers were used for the first time in water purification via ...

They are used in cleaning our drinking water, treating sewage, processing foods and keeping pharmaceuticals safe—membranes ...

Polymer electrolyte membrane (PEM) fuel cells employ a polymer membrane with acid side groups to conduct protons from the anode to cathode. Water management in the fuel cell is critical for PEM fuel ...

including the relationship between the membrane’s polymer backbone, ion content, and water uptake. Prof. Hickner will also describe the role of water in conducting protons and hydroxide anions and ...

Therefore, scientists have been hard at work designing lightweight electrolytes—such as polymers that ... is generated as protons and water diffuse across these membranes. Researchers come ...

For the hydrophilic parts of the polymer main chain ... As expected, the higher IEC membranes exhibited greater water uptake. In QPE-bl-3 (X5Y9), the water uptake of TMA (149%) was greater ...

Designing a proton-exchange membrane that will balance the efficiency, durability and safety requirements for hydrogen ...

Aston Institute for Membrane Excellence (AIME) has been awarded £6.1 million in funding from the UK Government Department of Science, Industry and Technology (DSIT), with a further £7.1 million in ...
