Oxidation of Aquatic Organic Contaminants Induced by Excited Triplet States

CHIMIA, 2007
The developments of the last fifteen years in the field of triplet-induced degradation of aquatic organic contaminants are reviewed. There is increasing evidence that the elusive excited triplet states of colored dissolved natural organic matter

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean

Limnology and Oceanography Letters, 2023
The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters.

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Seasonal variation characteristics of dissolved organic matter composition and cycle process in caves

Carsologica Sinica, 2023
Dissolved organic matter (DOM) is the key part and important carbon source of karst carbon sink. The migration and degradation of DOM in karst aquifers is an important carrier of material and energy transfer.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Arctic biogeochemical and optical properties of dissolved organic matter across river to sea gradients

Frontiers in Marine Science, 2022
Arctic landscapes are warming and becoming wetter due to changes in precipitation and the timing of snowmelt which consequently alters seasonal runoff and river discharge patterns.

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

Advanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

On the light absorption characteristics of colored dissolved organic matter in Lake Dianshan

Journal of Lake Sciences, 2007
This paper focuses on the spectral absorption characteristic of colored dissolved organic matter (CDOM) in Lake Dianshan,which is the source of Huangpu River in Shanghai.The relationships between CDOM and water quality parameters,including chlorophyll a (Chl.a),turbidity and chemical oxygen demand (COD) were investi- gated.Spectral absorption shapes in
