Artificial electrocatalytic ammonia (NH 3) synthesis is recently becoming a research hotspot.
It can couple with clean renewable electricity, which is considered an energy-efficient and …

Renewable power-to-fuel (PtF) is a key technology for the transition towards fossil-free
energy systems. The production of carbon neutral synthetic fuels is primarily driven by the …

Cropland is a main source of global nitrogen pollution,. Mitigating nitrogen pollution from
global croplands is a grand challenge because of the nature of non-point-source pollution …

Excessive agricultural nitrogen use causes environmental problems globally, to an extent
that it has been suggested that a safe planetary boundary has been exceeded. Earlier …

Globally increasing nitrogen (N) deposition is recognized as an important regulator of soil
microbial communities. However, how N enrichment affects soil microbial diversity, richness …

Input–output estimates of nitrogen on cropland are essential for improving nitrogen
management and better understanding the global nitrogen cycle. Here, we compare 13 …

Proton-coupled electron transfer (PCET) underpins energy conversion in chemistry and
biology. Four energy systems are described whose discoveries are based on PCET: the …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Executive summary Food systems have the potential to nurture human health and support
environmental sustainability; however, they are currently threatening both. Providing a …

Nitrogenase is the enzyme that catalyzes biological N2 reduction to NH3. This enzyme
achieves an impressive rate enhancement over the uncatalyzed reaction. Given the high …
