From atoms to a data bank: optimizing transferability of electron‐density symmetry

Acta Crystallographica Section A, Volume 82, Issue 4, Page 256-275, July 2026.
This work focuses on the electron density of atoms modeled with a multipolar approach. We investigate how the refinement of the multipole models with/without symmetry constraints and optimization of the orientation of the local coordinate system and pseudosymmetry assignment improves the accuracy of electron‐density representations for atoms and atom ...

Principles of Food Safety and Toxicological Risk Assessment: Refining Hazards, Risk Management Communication, and Common Misconceptions

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Toxicology has evolved into a robust scientific discipline since the 16th century when Paracelsus, the “Father of Toxicology,” established the basic yet fundamental principle that “the dose makes the poison.” Toxicology is often first associated with the chemical and pharmaceutical industries; however, it plays an equally relevant role in ...

Rational Design of Crown Ether‐Based Fluorescent Sensors for Group II Cations: Insights From Vibrational Spectroscopy and Computation

ChemPhysChem, Volume 27, Issue 12, 26 June 2026.
We use vibrational spectroscopy to determine the solution phase structures of complexes of two fluorescent sensors with metal ions. We use these to understand differences in the absorption spectra and to explain why even very low levels of water destroy the fluorescent response. Rational design of fluorescent sensors requires knowledge of the molecular

Morphological Control of Aurophilic Chains of Gold(I) Dithiolate Dimers With Alkali and Alkali Earth Cations

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Luminescent coordination polymers of Group 1 (Li, K, Cs) and 2 (Mg─Ba) cations with gold(I) iso‐maleonitriledithiolate ({Au2[S2C = C(CN)2]}2−) units were prepared; 1‐D aurophilic chains are present in all cases. The structures strongly depend on cation charge and size, with N‐cyano coordination observed in the Gp 1 and larger Gp 2 cations. Increasingly

Perchlorate Removal in groundwater by perchlorate reductases from the perchlorate respiring bacterium, perc1ace

, 2003
[Note: See PDF for correct symbols.] Perchlorate (ClO4-) is an important energetic component of solid rocket fuel. The major source of ClO4- pollution is the military, space program and supporting industries. ClO4- is recalcitrant in the environment and is potentially toxic.
