Eu(II) Complexes as Model Systems for Spin‐Only Metal Polarizing Agents for Solid Effect DNP

Analysis &Sensing, Volume 6, Issue 3, May 2026.
This study introduces Eu(II)‐[2.2.2]cryptand as a model polarizing agent for solid effect dynamic nuclear polarization (DNP). By analyzing the roles of nuclear spin (I = 5/2) and zero‐field splitting in an S = 7/2 system, the authors reproduce electron paramagnetic resonance (EPR) and DNP behavior across various field strengths.

Quantitative Real‐Time MRI for the Assessment of Gastric Motility

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1482-1495, May 2026.
ABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

Synergistic Photophysical and Mechanical Enhancement in Europium Supramolecular Hydrogel by Incorporating Gd(DPA)3 Complex (DPA = Dipicolinate)

ChemistryOpen, Volume 15, Issue 5, May 2026.
Lanthanide‐based hydrogels incorporating Ln(DPA)3 complexes are synthesized and exhibit enhanced mechanical and luminescent properties. Increased complex concentration improves stiffness and emission intensity without altering coordination symmetry. Computational insights reveal preserved structural features, while lifetime changes highlight hydrogel ...

Membrane Vesicle Formation Removes Iron Sulfide Mineral Crusts From the Cell Surface of Growing Sulfate‐Reducing Bacteria

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT Sulfate‐reducing bacteria (SRB) drive the process of sulfate reduction in low‐temperature sedimentary environments. Through the production of sulfide, they promote the formation of iron‐sulfide (Fe‐S) minerals when Fe(II) is available. The negative charge of the cell surface of bacteria can promote the binding of Fe(II), leading to the ...

Zwitterionic Mn(III)‐Tetraphenyl Porphyrins: Water‐Soluble MRI Contrast Agents with High Relaxivity

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Mn(III)‐based contrast agents (MBCAs) are promising and potentially safer alternatives to the Gd(III)‐based contrast agents (GBCAs) currently used in MRI. This study reports the synthesis, physicochemical characterization and first in vivo application of novel Mn(III)‐tetraphenylporphyrin chelates, bearing zwitterionic sulfobetaine or N‐oxide groups ...

Inorganic Photoluminescent Microparticles as Identifiers for the Sorting of Lithium‐Ion Battery Cathodes

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
The growing demand for lithium‐ion batteries in the European Union contributes to critical raw material scarcity. This challenge can be addressed by establishing a circular economy, making use of highly efficient and economical recycling processes. The efficiency of these processes depends on high‐purity material streams and thus on the availability of

Multiple Dimerization Modes in Thiocarboxylate Paddlewheel Complexes: A Comprehensive View of Energy Landscapes from DFT Calculations and Statistics

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...
