Phenolic and Acidic Compounds in Radiation Fog at Strasbourg Metropolitan

Atmosphere
Sixty-four phenols grouped as nitrated, bromo, amino, methyl, chloro-phenols, and cresols, and thirty-eight organic acids grouped as mono-carboxylic and dicarboxylic are analyzed in forty-two fog samples collected in the Alsace region between 2015 and ...

Green and Low‐Carbon Synthesis of Lithium Sulfide (Li2S): From Fundamental Mechanisms to Scalable Manufacturing for Next‐Generation Energy Storage

Advanced Science, EarlyView.
This review focuses on green synthesis routes for lithium sulfide (Li2S)—a key material for lithium–sulfur batteries and sulfide solid electrolytes, whose traditional carbothermal reduction remains energy‐intensive and unsustainable. Specifically examined routes include low‐temperature solid‐state reactions, magnesiothermal reduction, and solution ...

S8-mediated decarboxylative cyclization of 2-nitrophenols with arylacetic acid: Synthesis of benzoxazoles

Journal of Saudi Chemical Society, 2019
A concise, metal-free protocol has been established for the preparation of 2-arylbenzoxazoles from 2-nitrophenols and arylacetic acids via a sulfur-mediated redox decarboxylative cyclization reaction.

Tailored Covalent Organic Frameworks Enable the Encapsulation of Living Cells to Produce Rare Ginsenoside

Advanced Science, EarlyView.
This work reports the in situ fabrication of Escherichia coli@covalent organic frameworks (E. coli@COFs) in phosphate‐buffered saline. The COFs form an exoskeleton on E. coli, protecting intracellular β‐glucosidase (Ssbgl) while enhancing mass transfer.

Prediction of the By-products Formation in the Adiabatic Industrial Benzene Nitration Process

Chemical Engineering Transactions, 2013
Side reactions are undesirable in most industrial processes, as they decrease process yield and selectivity. For this reason, mononitrobenzene’s manufacturers set nitrophenols minimization as a critical goal, along with the MNB production targets.

Accumulation and transport of phenol, 2-nitrophenol, and 4-nitrophenol in plant cuticles

Ecotoxicology and Environmental Safety, 1985
Partition (K) and permeance (P) coefficients have been determined for phenol, 2-nitrophenol, and 4-nitrophenol with isolated cuticles from mature tomato (Lycopersicon) and green pepper (Capsicum) fruits and from the adaxial surface of rubber (Ficus) leaves.

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
