Oxidation of propene from air by atmospheric plasma-catalytic hybrid system [PDF]

open access: yesJournal of the Serbian Chemical Society, 2018
The pulsed dielectric barrier discharge (DBD) combined with the palladium supported on alumina beads, was investigated for propene (C3H6) removal from air. The effects of thermal-catalysis, plasma-catalysis (in-plasma catalysis and post-plasma catalysis),

A two-step approach to achieve secondary amide transamidation enabled by nickel catalysis. [PDF]

open access: yes, 2016
A long-standing challenge in synthetic chemistry is the development of the transamidation reaction. This process, which involves the conversion of one amide to another, is typically plagued by unfavourable kinetic and thermodynamic factors. Although some
