Abstract: Tautomerizations of succinimide (2,5-pyrrolidinedione) and maleimide (2,5-pyrroledione) assisted by ammonia and methanol molecules have been studied at density functional theory level in aqueous medium implementing polarizable continuum model. Tautomerisms observed in succinimide are keto–enol and… read more here.

DOI: 10.1016/j.combustflame.2021.02.016
Abstract: Abstract This work reports that plasma can simultaneously reduce NOx emission and extend the lean blowoff limits of ammonia flames. The results show dramatic differences from similar work using hydrocarbon fuels in which plasma promoted… read more here.
