Kinetics of rapid covalent bond formation of aniline with humic acid: ESR investigations with nitroxide spin labels [PDF]

, 2016
The bioavailability of many soil contaminants depends on their interaction with the soil organic matter. The paper presents a new approach of using stable paramagnetic spin labels for investigating the kinetics of covalent binding of specific xenobiotic ...

A Polymer‐Intercalated Modulation Assembly Strategy Towards Mesoporous Single‐Crystalline BiVO4 Materials for Enhanced Photocatalytic Performance

Advanced Science, Volume 13, Issue 19, 2 April 2026.
A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...

N,N’‐Dialkylated Oxo‐Verdazyl Radicals as Bipolar Organic Molecules for Symmetric Redox Flow Batteries

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
In this work, N,N’‐dialkylated oxo‐verdazyl radicals have been studied in redox flow batteries for the first time. Investigation of the degradation led to the identification of a decomposition product. By that, the molecular design and the cycling performance could be improved.

Cobalt(II) Terpyridin-4′-yl Nitroxide Complex as an Exchange-Coupled Spin-Crossover Material [PDF]

, 2018
pin-crossover (SCO) was studied in [Co(L)2](CF3SO3)2, where L stands for diamagnetic 2,2′:6′,2′′-terpyridine (tpy) and its paramagnetic derivative, 4′-{4-tert-butyl(N-oxy)aminophenyl}-substituted tpy (tpyphNO).

T1/T2 Proportional Magnetic Resonance Nanoprobe Monitoring Tumor Autophagy during Chemotherapy

Nanomaterials
Autophagy leads to cellular tolerance of the therapeutic pressure of chemotherapeutic drugs, resulting in treatment resistance. Therefore, the effective monitoring of the autophagy status of tumors in vivo and the regulating of the autophagy level are ...

Radicals, Metals and Magnetism [PDF]

, 1998
The interaction between unpaired electrons governs many physical properties of materials. Although in a fundamental sense the interaction is simple, a full understanding of the interaction in molecular systems is complicated by the presence of other ...
