Abstract: Abstract Nitrous oxide (N2O) is one of the most powerful greenhouse gases, emitted by ammonia-oxidizing bacteria (AOB) and denitrifier during nitrogen transformation. A laboratory-scale sequencing batch reactor with enriched nitrifiers was developed under oxygen-limited conditions… read more here.

DOI: 10.1107/s2053229618008227
Abstract: Proton conduction in crystalline porous materials has received much attention from basic scientific research through to practical applications. Polyoxometalates (POMs) can efficiently transport protons because of their small superficial negative charge density. A simple method… read more here.
