Experimental and Theoretical Studies on Reaction Kinetics, Mechanism, and Degradation of Quinoline‐Based Herbicide with Hydroxyl Radical, Sulphate Radical Anion, and Hydrated Electron

ChemPhysChem, EarlyView.
Advanced oxidative process is commonly used for the degradation/removal of herbicides from soil/water bodies. It mostly involves oxidizing •OH and SO4•−$\text{SO}_{4}^{\cdot -}$ species. The present study involves an experimental and theoretical approach to explore kinetics, mechanism, and degradation pathways for 8–quinoline carboxylic acid (8QCA ...

Novel approach to study fish oil oxidation using 1H nuclear magnetic resonance spectroscopy

Journal of Functional Foods, 2017
The oxidative degradation of omega-3 fatty acids-rich fish oil was investigated by 1H Nuclear Magnetic Resonance (NMR) Spectroscopy. The intensities of key distinct spectral signals corresponding to bis-allylic (RBAG) and terminal methyl groups (RO3TG ...

Molecular Fragmentation as a Strategy to Access Hyperpolarized Compounds from Para‐Hydrogen

ChemPhysChem, EarlyView.
Hyperpolarization using para‐hydrogen is a simple and cost‐effective method to dramatically increase sensitivity in magnetic resonance. When combined with chemical reactions that generate smaller fragments, a much wider array of different hyperpolarized molecules can be accessed.

MODIFICATION OF LIGNANS BY TRAMETES HIRSUTA LACCASE

BioResources, 2009
Oxidative polymerization of two isolated lignans, secoisolariciresinol, and secoisolariciresinol diglucoside, as well as the lignan macromolecule, by a high redox potential Trametes hirsuta laccase was studied with different analytical methods.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

En Route Toward Sustainable Polycarbonates via Large Cyclic Carbonates

ChemSusChem, EarlyView.
The use of safe carbonylating agents, allowed by a suitable (bio)catalytic systems, affords the sustainable and green synthesis of large‐ring cyclic carbonates by reaction of renewables such as bio‐based diols. These carbonates are prone to ring‐opening polymerization paving the way for the production of circular aliphatic polycarbonates.

Electrochemical Three‐component Synthesis of Alkenesulfonates from Cinnamic Acids, SO2, and Alcohols

ChemSusChem, EarlyView.
An electrochemical three‐component synthesis of alkyl alkenesulfonates from cinnamic acids, SO2, and alkyl alcohols is reported. This metal‐free process employs inexpensive and readily available graphite electrodes in combination with easy‐to‐use stock solutions of SO2 and enables a straightforward decarboxylative preparation of styrene sulfonates via ...
