Chemical looping ammonia synthesis (hereafter referred to as CLAS) decouples the overall ammonia synthesis reaction into several step-wise reactions
With regard to the CLAS with H2 as the hydrogen source, there are two types of nitrogen carriers reported so far, i.e., transition metal nitrides (denoted as TMNs) and alkali or alkaline earth metal imides (denoted as ANHs), respectively.
Schematic diagram of CLAS mediated by the MnNx–ANH composite N carrier. AH stands for LiH or BaH2, and ANH stands for Li2NH or BaNH.

Cobalt Single Atoms Embedded in Nitrogen-Doped Graphene for Selective Oxidation of Benzyl Alcohol by Activated Peroxymonosulfate
DOI: 10.1002/smll.202004579
the dynamically catalytic effect of single cobalt atoms embedded in nitrogen-doped graphene for selective oxidation of BzOH by activated peroxymonosulfate.
The incorporated Co atoms function as active sites for Peroxymonosulfate (PMS) activation via both radical and non-radical pathways.
reactive •OH, SO4•−, and SO5•− radicals
the catalyst-mediated electron transfer by surface complexed substrate/PMS and the singlet oxygen ($SUP{1};O$SUB{2};).
if the 1O2 is able to induce the non-radical oxidation of BzOH, BzH can also be oxidized by 1O2.

Synthesis and Properties of Higher Nuclearity Polyazanes
DOI: 10.1002/chem.202004830
polyazanes are a new class of nitrogen-containing molecules that until now had not been considered as a
family with similar properties. We showed that this is indeed the case, as similarly substituted polyazanes with growing numbers of linked nitrogen atoms gradually fold to form helices and become increasingly less oxidizable.

Improving the Level of the Tyrosine Biosynthesis Pathway in Saccharomyces cerevisiae through HTZ1 Knockout and Atmospheric and Room Temperature Plasma (ARTP) Mutagenesis
DOI: 10.1021/acssynbio.0c00448
Atmospheric and room temperature plasma (ARTP) mutagenesis can induce breakage in plasmid DNA and oligonucleotides through treatment with a diverse range of plasma doses. (15 Appl. Microbiol. Biotechnol. 98, 5387−5396.)
NK-B2 was subsequently used as the starting strain to further enhance the production of tyrosine by ARTP mutagenesis.
Under the reaction catalyzed by tyrosine hydroxylase and DOPA dioxygenase (DOD), betalamic acid is converted from tyrosine, and finally, betaxanthins are produced through a spontaneous reaction between free
amines or amino acids and betalamic acid. (48 Plant Cell Physiol. 50, 1012−1016.; 49 Trends Plant Sci.
18, 334−343. )
