Recent Advances in Single‐Atom Nanozymes for Improved Food Safety and Nutritional Analysis

open access: yesInternational Journal of Food Science, Volume 2026, Issue 1, 2026.
Single‐atom nanozymes (SANz) have attracted considerable interest due to their remarkable catalytic characteristics, which are ascribed to individual metal atoms anchored to different supports. High atom utilization, adjustable activity, and exceptional stability are some of the advantages of nanozymes.

Spatial Variation in Nutrient and Water Color Effects on Lake Chlorophyll at Macroscales

open access: yesPLOS ONE, 2016
The nutrient-water color paradigm is a framework to characterize lake trophic status by relating lake primary productivity to both nutrients and water color, the colored component of dissolved organic carbon. Total phosphorus (TP), a limiting nutrient, and water color, a strong light attenuator, influence lake chlorophyll a concentrations (CHL).

Drought Offsets the Controls on Colored Dissolved Organic Matter in Lakes

open access: yesRemote Sensing
The concentration of colored dissolved organic matter (CDOM) in lakes is strongly influenced by climate, land cover, and topographic settings, but it is not known how drought may affect the relative importance of these controls. Here, we evaluate the controls of CDOM during two summers with strongly contrasting values of the Palmer drought index (PDI),

Phytoplankton in humic and colored Nordic lakes

open access: yes, 2020
Concentrations of lake dissolved organic carbon (DOC) transported from catchments, with simultaneous browning, are currently increasing in boreal lakes, and predicted to continue in the future. This increased load of organic matter has several complex effects on lake physiology and chemistry.
