However, limited progress has been made to date, as most electrocatalyst surfaces lack specificity towards nitrogen fixation. In this Review, we discuss the progress of the field in developing a mechanistic understanding of nitrogenase-promoted and molecular catalyst-promoted ammonia synthesis and provide...

As whole-body production of metabolites is suppressed, amino acids with nitrogenous side chains accumulate during torpor, while urea cycle intermediates do not. Using 15N stable isotope methodology in arctic ground squirrels (Urocitellus parryii), we provide evidence that free nitrogen is buffered and...
Qingyan Fu4, Song Gao1,4, Dongfang Wang1,4, Huxiong Cui4, Alfonso Saiz-Lopez3 & Bin Zhou1,5 Atmospheric ammonia (NH3) has great environmental implications due to its important role in ecosystem and global nitrogen cycle, as well as contribution to secondary particle formation....
000 cycles for each cycle. The experiment to determine the amount of adsorbed N2was conducted at the milling speed of 400 r.p.m. for 1.5, 2.5, 4.5, 9, and 18 h for each. In addition, to prepare the nitrogen-doped catalyst (FeKN*) for hydrogenation, the experiment was conducted ...
Ammonia oxidation plays an important role in the global nitrogen cycle. Many studies have focused on ammonia-oxidizing communities in various habitats, including ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) and complete ammonia oxidizers (comammox). NA-SIP can be used to sp...
