Graphene modified fluorinated cation-exchange membranes for proton exchange membrane water electrolysis [PDF]
International Journal of Hydrogen Energy, 2019 Abstract One of major current technical challenges in proton exchange membrane water electrolysis (PEMWE) is the limited proton conductivity. Nowadays, graphene is considered one of the most promising candidates for improving the ionic transport properties, isotopic selectivity and proton conductivity throughout the unique two-dimensional structure ...

Unification Scale, Proton Decay, And Manifolds Of G_2 Holonomy [PDF]
, 2002 Models of particle physics based on manifolds of $G_2$ holonomy are in most respects much more complicated than other string-derived models, but as we show here they do have one simplification: threshold corrections to grand unification are particularly ...
