   Gilbert-Bass, Kito; Stennett, Cary R.; Grotjahn, Robin; Ziller, Joseph W.; Furche, Filipp; Evans, William J. (April 2024, Chemical Communications)

   To expand the range of donor atoms known to stabilize 4fⁿ5d¹Ln(ii) ions beyond C, N, and O first row main group donor atoms, the Ln(iii) terphenylthiolate iodides, Ln^III(SAr^iPr6)₂I (Ar^iPr6= C₆H₃-2,6-(C₆H₂-2,4,6-ⁱPr₃)₂, Ln = La, Nd) were reduced to Ln^II(SAr^iPr6)₂complexes.

4. MHD Simulations of Strongly Magnetized H ii Region Evolution: Evidence for Ionized Gas Filamentation

   https://doi.org/10.3847/1538-4357/ae4bd7

   Abstract Recent James Webb Space Telescope observations of Hii regions in the Central Molecular Zone (CMZ) have shown a highly filamentary morphology distinct from Hii regions in other parts of the Galaxy. We present magnetohydrodynamic (MHD) simulations of strongly magnetized (plasma-β ≪ 1) Hii region evolution that investigate and describe the formation of these ionized gas filaments. Hii region evolution has been simulated in a 30 pc³box, in distinct models with preplaced overdensities in the ambient medium and overdensities that have been generated with driven turbulence. We find that when these overdensities are seeded in the ambient medium before the birth of the ionizing source, the photoionized plasma stripped off of these dense blobs is funneled into long filaments along the magnetic field lines. The length and emission measure of these ionized gas filaments are similar to the filaments observed in the CMZ. Given that these filaments are effectively magnetically confined flows of photoionized gas, their density and curvature are influenced by the density of the blob and the geometry of the configuration.

5. Redox-responsive Fe( ii )/Fe( iii ) MRI probes with pentadentate or hexadentate macrocyclic ligands

   https://doi.org/10.1039/D6QI00660D  

   Balaji, Deepak Krishnan; Spernyak, Joseph A; Crawley, Matthew R; Morrow, Janet R (June 2026, Inorganic Chemistry Frontiers)

   Redox-responsive Fe(ii)/Fe(iii) MRI probes are activated by micromolar peroxide concentrations relevant to physiological conditions. Complexes with hexadentateversuspentadentate ligands show different reactivity towards peroxide and O₂.
