Soils and sediments are major reservoirs of organic matter (OM), whose dynamic turnover
has a major impact on carbon cycling and global climate. OM in soils and sediments is …

Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Mechanisms of soil organic carbon (SOC) stabilization have been widely studied due to their
relevance in the global carbon cycle. No‐till (NT) has been frequently adopted to sequester …

The biogeochemical cycling of soil organic matter (SOM) plays a central role in regulating
soil health, water quality, carbon storage, and greenhouse gas emissions. Thus, many …

Soil organic matter (SOM) is the largest actively cycling reservoir of terrestrial carbon (C),
and the majority of SOM in Earth's mineral soils (~ 65%) is mineral‐associated organic …

Permafrost thaw can stimulate microbial decomposition and induce soil carbon (C) loss,
potentially triggering a positive C-climate feedback. However, earlier observations have …

Ice-rich Pleistocene-age permafrost is particularly vulnerable to rapid thaw, which may
quickly expose a large pool of sedimentary organic matter (OM) to microbial degradation …

Iron (Fe) oxides are widely recognized to prevent the degradation of organic matter (OM) in
environments, thereby promoting the persistence of organic carbon (OC) in soils. Thus …

We report an unrecognized, tidal source of reactive oxygen species (ROS). Using a newly
developed ROS-trapping gel film, we observed hot spots for ROS generation within∼ 2.5 …

Despite substantial experimental evidence of electron transfer, atom exchange, and
mineralogical transformation during the reaction of Fe (II) aq with synthetic Fe (III) minerals …
