Semiconductor d‐Band Engineering for Enhanced Photocatalytic Nitrogen Fixation: Progress and Perspectives

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Regulating the d‐band center of semiconductors through elemental doping presents a promising strategy for enhancing the efficiency of photocatalytic nitrogen conversion. This review systematically summarizes recent advances in d‐band center engineering for photocatalytic nitrogen fixation.

Nitrous Oxide Accumulation in Braided Rivers Is Controlled by Interactions Between Seasons, Nitrate Availability, and Flow

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Human activities have increased reactive nitrogen inputs to rivers, intensifying the emissions of nitrous oxide (N2O). However, riverine N2O saturation is difficult to predict because it is influenced by both reactive nitrogen availability, particularly nitrate (NO3−), and hydrology.

A global dataset of nitrogen fixation rates across inland and coastal waters

Limnology and Oceanography Letters
Biological nitrogen fixation is the conversion of dinitrogen (N2) gas into bioavailable nitrogen by microorganisms with consequences for primary production, ecosystem function, and global climate.

Niche construction by non‐diazotrophs for N2 fixers in the eastern tropical North Atlantic Ocean

Geophysical Research Letters, 2017
Diazotrophic dinitrogen (N2) fixation contributes ~76% to “new” nitrogen inputs to the sunlit open ocean, but environmental factors determining N2 fixation rates are not well constrained.

Di-nitrogen fixation at the early and late growth stages of soybean

Acta Scientiarum. Agronomy, 2018
  Soybean derives a significant portion of the required nitrogen (N) from the symbiosis with rhizobia bacteria. However, information on the available genetic variation for N2 fixation capacity in different growth stages of soybean is limited.

Apportioning Sources of Nitrogen Oxides in California's San Joaquin Valley Using Observations From Three Airborne Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Emissions of nitrogen oxides (NOx = NO + NO2), a precursor to ozone and secondary aerosol formation have become increasingly important to understand as ozone production transitions to NOx limited in most regions of the US. Recent studies suggest that NOx emissions associated with agricultural activities, particularly cropland soils, are an ...

Diazotrophy in the Indian Ocean: Current understanding and future perspectives

Limnology and Oceanography Letters, 2023
Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean, sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface, while it only represents 1% of the global diazotroph database.
