Boosting Photocatalytic H2O2 Generation via Interfacial Engineering in a 2D S‐Scheme Hydroxyethyl Cellulose‐Modified Graphitic Carbon Nitride/Bismuth Oxybromide Heterojunction

Small Structures, Volume 7, Issue 5, May 2026.
An S‐scheme heterojunction of hydroxyethyl cellulose‐modified g‐C3N4 and BiOBr drives efficient photocatalytic H2O2 generation. Interfacial engineering creates a built‐in electric field, facilitating charge separation while preserving stron\g redox potentials. This 2D architecture delivers a remarkable 5897 μM g−¹ h−¹ H2O2 production rate under visible

Differential Drivers of Thermogenic and Bulk Dissolved Organic Matter in the Indian Ocean

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract The oceanic dissolved organic matter (DOM) pool contains a substantial fraction of recalcitrant carbon, with thermogenic organic compounds representing a chemically distinct, long‐lived component. However, the distribution and transformation of these compounds remain poorly constrained in the Indian Ocean, a key basin of the global overturning

Microbial Controls on Carbon Pump Partitioning in the Subtropical North Atlantic: Stoichiometry and Nutrient Limitation Across a Basin‐Scale Transect

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract The subtropical North Atlantic is a key region for ocean carbon cycling despite its relatively small spatial extent. Here we present a high‐resolution transect (23°–27°N; ∼2° longitude spacing) across the North Atlantic Subtropical Gyre, integrating physical, chemical, and microbial observations to examine how hydrography and nutrient ...

Network Connectivity and Local Hydrology Drive DOM Composition in a Nonperennial Stream

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Nonperennial streams are dynamic sites of biogeochemical processing, yet much remains to be learned about how hydrologic connectivity at different spatial and temporal scales impacts the composition of dissolved organic matter (DOM). We characterized spatial and temporal patterns of DOM composition in a nonperennial prairie stream network ...

In‐Lake GHG Production Constrained by Lake DOM Mass Balance in a Boreal Catchment

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The processing of organic carbon in surface waters represents a critical component of the carbon (C) cycle in boreal landscapes and is closely linked to greenhouse gas (GHG) emissions, primarily carbon dioxide (CO2) and methane (CH4). Utilizing a unique data set with dense monitoring of dissolved organic carbon (DOC), dissolved CO2, and CH4 at

Carotenoids are the likely precursor of a significant fraction of marine dissolved organic matter. [PDF]

, 2017
The ocean's biota sequester atmospheric carbon dioxide (CO2) in part by producing dissolved organic matter (DOM) that persists in the ocean for millennia.

Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...
