Visible-light-promoted catalyst-free benzylic C-H oxidation using molecular oxygen as a green oxidant. [PDF]
Smart MolA green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

Facilitated transport near the carrier saturation limit [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2002 Permeation of ethylbenzene, styrene and 1-hexene through perfluorosulfonate ionomer membranes was carried out with the feed concentrations ranging from 1 M to pure. On comparison, fluxes of ethylbenzene through the Ag+-form membrane were the lowest. Only
