Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

Chemistry – A European Journal, EarlyView.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Electrochemiluminescence of Heteroleptic Iridium(III) Complexes Featuring Substituted 2,4‐diphenylpyridinato Ligands

Chemistry – A European Journal, EarlyView.
Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Synthetic Approaches of Pyrazolyl Quinolines

, 2019
This review article represents a survey of the synthetic strategies leading to pyrazolyl quinolines. The synthetic methods are divided into two main groups based on the type of starting reagents: 1) From quinoline ring onto a pyrazole scaffold, 2) From

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Nitriles in heterocyclic synthesis: Novel syntheses of benzo[b]pyrans, naphtho[1,2-b]pyrans, naphtho[2,1-b]pyrans, pyrano[3,2-h]quinolines and pyrano[3,2-c]quinolines

, 1988
Benzo[b]pyrans, naphtho[1,2-b]pyrans, naphtho[2,1-b]pyrans, pyrano[3,2-h]quinolines, and pyrano[3,2-c]quinolines were synthesized by the reaction of cinnamonitriles with phenols, naphthols, 8-hydroxyquinoline, and 1-methyl-4-hydroxy-2-quinoline.
