Dissolved organic carbon and nitrogen dynamics in the Douro River estuary, Portugal

Ciencias Marinas, 2008
Dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) are metabolically important in estuaries. Their availability is influenced by organic matter inputs (internal and external) as well as by internal microbial transformations within the ...

Compositional variations in algal organic matter during distinct growth phases in karst water

Frontiers in Environmental Science, 2023
Inland surface water plays an important role in global carbon cycling, which responds to transformation between dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC).

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

The Climate Control of Soil Organic Carbon Dynamics Inferred From Speleothem Radiocarbon Ages

Geophysical Research Letters, 2023
The complexity of processes affecting soil organic carbon (SOC) turnover on spatio‐temporal scales often hinders the extrapolation of results from specific sites to larger scales.

Origin of dissolved organic carbon under phosphorus-limited coastal-bay conditions revealed by fluorescent dissolved organic matter

Frontiers in Marine Science, 2022
To determine the origins of dissolved organic carbon (DOC) in a bay of volcanic Jeju Island, where the discharge of fresh groundwater (FGW) is dominant, we measured fluorescent dissolved organic matter (FDOM) and implemented a parallel factor analysis ...

Latitudinal Gradients in Degradation of Marine Dissolved Organic Carbon

PLoS ONE, 2011
Heterotrophic microbial communities cycle nearly half of net primary productivity in the ocean, and play a particularly important role in transformations of dissolved organic carbon (DOC). The specific means by which these communities mediate the transformations of organic carbon are largely unknown, since the vast majority of marine bacteria have not ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Carbon in an Arctic fjord: sea ice carbon transformations and CO2 linkages

Frontiers in Marine Science
IntroductionThe biogeochemical processes underlying carbon cycling in Arctic coastal systems are rapidly evolving due to intensified ice loss. (Aim) This study examined the distinct contributions of dissolved organic carbon (DOC) and particulate carbon ...

Characterization of Laboratory-scale Tidal Flow Constructed Wetlands in the Removal of Organic Carbon and Nitrogen from Sewage

Journal of Water and Environment Technology, 2023
Tidal flow constructed wetlands (TFCWs) have been proposed as a new type of CW for enhanced wastewater treatment. However, the characterization of TFCWs in the removal of organic carbon and nitrogen remains unclear.
