Free-radical propagation rate coefficients of dodecyl methacrylate deduced from electron spin resonance experiments

, 1998
Propagation rate coefficients (kp) for the free-radical polymerization of dodecyl methacrylate (DMA) in solution in toluene have been measured via electron spin resonance (ESR) spectroscopy in the temperature range O to 50 °C.

Electron spin resonance of the Kondo ion in YbRh2Si2 [PDF]

, 2004
By means of electron spin resonance (ESR) we investigated the dynamic magnetic properties of the heavy fermion metal YbRh2Si2. This is the first observation of Yb3+-ESR in YbRh2Si 2 being also the first ESR signal of a Kondo ion in a dense Kondo lattice ...

Redox‐Switchable Optical and Magnetic Properties in a Self‐Assembled Hexanuclear Ni(II) Double‐Decker Complex

Chemistry – A European Journal, EarlyView.
A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

Azoimidazolium Salts as a Platform for Persistent Neutral Aminyl Radicals and Mesoionic Carbene Au(I) Complexes as Cell‐Permeable Fluorophores

Chemistry – A European Journal, EarlyView.
Strategic electronic matching between imidazolium salts and aryldiazonium salts enables a chromatography‐free route to versatile azoimidazolium scaffolds. Fine‐tuning the substituents unveils a powerful dichotomy: strong ─OMe resonance stabilizes highly persistent neutral aminyl radicals (up to 3 weeks), whereas the superior ─NMe2 donor strength yields

Spin fluctuations in the quasi-two-dimensional Heisenberg ferromagnet GdI₂ studied by electron spin resonance

, 2004
The spin dynamics of GdI2 have been investigated by electron spin resonance (ESR) spectroscopy. The temperature dependences of the resonance field and ESR intensity are well described by the model for the spin susceptibility proposed by Eremin [Phys. Rev.

ESR study of the undoped heavy-fermion compound YbRh2Si 2

, 2020
The electron spin resonance (ESR) of the heavy-fermion metal YbRh 2Si2 has been studied. The angular variation and the temperature dependence of the ESR line width have been measured in YbRh 2Si2 single crystals in the temperature range of 4-25 K.

Reversible Humidity‐Induced Vapochromism of a Cu(II) Tetramine Complex Driven by Iodide Access

Chemistry – A European Journal, EarlyView.
A humidity‐responsive Cu(II) vapochromic complex based on reversible iodide coordination is reported. Unlike the chloride and bromide analogues, [Cu(chxn)2(H2O)2]I2 exhibits rapid and reversible color changes with humidity. Spectroscopic, diffraction, ESR, and DFT studies reveal that dehydration induces axial iodide coordination to form [Cu(chxn)2I2 ...

Spin dynamics and charge transfer in C60 · 2ferrocene studied by electron spin resonance

, 2008
Electron spin resonance (ESR) has been applied to study spin dynamics and charge transfer interactions in C60(Fe(C5H5)2)2. A low concentration of C60- spins is derived by ESR, suggesting the presence of weak charge transfer between C60 and ferrocene. The

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.
