New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal

, 2016 Bond dissociation energies (BDEs) of M+[c-(C2H4O)5] and M+[c-(C2H4O)6] for M = Na, K, Rb, and Cs are reported. The BDEs are determined experimentally by analysis of the thresholds for collision-induced dissociation of the cation−crown ether complexes by ...

Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles
Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.We report the synthesis and characterization of a sulfated prism[5]arene host (Prism[5]MaxQ). Prism[5]MaxQ displays ultrahigh binding affinity (Ka up to 1012 M−1) toward hydrophobic (di)cations in phosphate‐buffered saline (PBS). The work positions Prism[5]MaxQ as a new member of the family of ultrahigh‐affinity hosts poised for use as a sequestrant in

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity
Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...

The synthesis of crown ethers for selective chelation of alkali metal ions
, 1995 Crown ethers of varying ring sizes have been used as selective chelators of radioactive alkali metal ions. The crown ethers capture cations with an ionic diameter fitted to their cavity size forming primarily 1:1 metal-crown ether complexes.
