Self-healing proton-exchange membranes (PEMs) made of poly(vinyl alcohol) (PVA) and Nafion were synthesized using the freeze-thaw method. Since PVA is more selective towards water than methanol, blend membrane successfully reduced methanol permeability improved selectivity compared to recast membrane. The addition also helped self-heal by promoting formation hydrogen bonds. In contrast pristine...

Frontispiece: In article number 2000776, Andriy Horechyy, Iryna Yevchuk, Andreas Fery, and co-workers present a series of hybrid proton conducting membranes composed covalently cross-linked interpenetrating polymeric silica networks. The effects monomer composition, sol–gel composition fraction on performance are investigated discussed. These novel hold promise for the application in direct met...

Ethanol is receiving great interest as an alternative fuel. Methanol is another alcohol fuel that could serve as a replacement for gasoline. Although it is currently receiving much less attention, it has the potential to play an important role. Like ethanol, methanol also has the advantage of being a liquid fuel and it can be produced from gasification of a variety of feedstocks using well esta...
