Permeation of CO₂ and N₂ through glassy poly(dimethyl phenylene) oxide under steady- and presteady-state conditions [PDF]
, 2020 Glassy polymers are often used for gas separations because of their high selectivity. Although the dual‐mode permeation model correctly fits their sorption and permeation isotherms, its physical interpretation is disputed, and it does not describe ...

Dual-mode photoswitching of luminescence [PDF]
Journal of the Chemical Society, Chemical Communications, 1995 The fluorescence and chirality of photoswitchable inherently dissymmetric alkenes cis 1 and trans-2-nitro-7-dimethylamino-9-(2',3'-dihydro-1'H-naphtho[2,1-b]thiopyran-1'-ylidene)-9H-thioxanthene 2 are reversibly modulated by irradiation whereas photoresponsive effects and emission are regulated by reversible protonation.
