Overview on the Increasing Trends and Their Influencing Factors of Long-term Monitoring of Water Dissolved Organic Carbon

Shuitu baochi yanjiu, 2009
There are long-term increases in surface water dissolved organic carbon（DOC） on the American and the European long-term monitoring sites.Dissolved organic carbon affects the functioning of aquatic ecosystems through its influence on the increases in ...

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 ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

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.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

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.

Low volume quantification of dissolved organic carbon and dissolved nitrogen [PDF]

Limnology and Oceanography: Methods, 2012
A method for the quantification of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) in aqueous samples of less than 600 µL is described. Analysis of low volumes is achieved through modification of a Shimadzu HTC TOC analyzer, which in its conventional configuration requires at least 7 mL sample. The modification allows manual injection
