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 ...

"The polymer-based membrane used in this study satisfies the fundamental requirement for robust, effective materials in the production of green hydrogen to be used in water electrolysis," Miyatake ...

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 ...

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 ...

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 ...

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 ...
