The Role of Ion Size and π‐Interaction in Stabilizing Calix[4]arene Crown Ether Metal Complexes
Chemistry – A European Journal, Volume 31, Issue 40, July 17, 2025.This work investigates MAXCalix's ability to coordinate alkali and alkaline earth metal ions, showing a preference for larger ions like Cs⁺. Structural analysis confirms that π‐interactions with benzene rings enhance stability, particularly for large cations that engage both rings.

Structural and Spectroscopic Trends in Alkali Tris(Acetato)Actinyl(VI) Complexes
European Journal of Inorganic Chemistry, Volume 28, Issue 19, July 12, 2025.Alkali tris(acetato) actinyl(VI) complexes of different actinyls and identical alkali metals are mostly isostructural, showing a redshift in the symmetric actinyl stretch across the actinide series. With increasing alkali ionic radii, a progression to lower symmetry is observed that correlates with subtle changes in the electronic and vibrational ...

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.Chiral COSAN Nanocatalysts: Enantiopure silica COSAN‐Hybrid nanohelices have been prepared by electrostatic co‐assembly of achiral COSAN anions and silica hybrid nanohelices. Their optical activity was confirmed by CD and ROA measurements. These COSAN‐Hybrids are efficient and recoverable catalysts in the photooxidative kinetic resolution of aromatic ...

AAPM medical physics practice guideline 13.a: HDR brachytherapy, part B
Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.Abstract The goal of this report is to assist the clinical medical physicist in assuring that key quality standards and practice considerations are met to ensure safe, reliable, and reproducible high dose rate (HDR) brachytherapy (BT) treatment. This guideline has been developed to provide appropriate minimum standards for such services.
