Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters
Frontiers in Microbiology, 2018 Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation
Advanced Science, EarlyView.By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...

Advanced Science, EarlyView.An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.

Suspended particle and pathogen peak discharge buffering by a surface-flow constructed wetland
, 2013 Constructed wetlands (CWs) have been shown to improve the water quality of treated wastewater. The capacity of CWs to reduce nutrients, pathogens and organic matter and restore oxygen regime under normal operating conditions cannot be extrapolated to ...

Advanced Science, EarlyView.This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Influences of particulate matter transport, export, and sedimentation on microbial community ecology
, 2019 Biddle, Jennifer F.It is well-documented that particulate prokaryotic communities differ from their free-living counterparts, yet the ecology of particle-associated bacteria is better understood than of the archaea.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes
Advanced Science, EarlyView.In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...
