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 ...

Remediation of chlorinated aliphatic hydrocarbons (CAHs) contaminated site coupling groundwater recirculation well (IEG-GCW®) with a peripheral injection of soluble nutrient supplement (IEG-C-MIX) via multilevel-injection wells (IEG-MIW)

Heliyon, 2022
An innovative Groundwater Circulation Well (GCW) process was configured, installed, and tested for optimizing the distribution of a soluble nutrient supplement in a heterogeneous aquifer for reductive dehalogenation.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Late‐Stage Modification of Halotryptophan‐Containing Peptides Via Negishi Cross‐Coupling

Chemistry – A European Journal, EarlyView.
Negishi cross‐coupling provides access to the late‐stage functionalization of bromotryptophan‐containing peptides under comparatively mild conditions and is applicable to a range of peptide substrates in the investigated model systems. The examined alkyl iodides and variation of N‐terminal residues demonstrate the feasibility of the transformation in a

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

Extracellularly Activatable Conjugates of RGD Peptidomimetics and Cryptophycin for αVβ3‐Targeted Cancer Therapy

Chemistry – A European Journal, EarlyView.
Integrin αVβ3‐targeting small‐molecule drug conjugates (SMDCs) were synthesized by conjugating a cryptophycin payload through a neutrophil elastase‐cleavable NPV‐PABC linker. RGD peptidomimetic and linker epimers served as controls for targeting and enzymatic cleavage, and the resulting conjugates displayed subnanomolar cytotoxicity in vitro.
