Does Aromaticity Drive Metal Cation Binding to Nanographenes? Insights Into Regioselectivity and Cation‐π$$ \pi $$ Bonding

open access: yesJournal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
Aromaticity of a ring by itself does not explain the binding energies of alkali and alkaline earth metal cations with nanographenes, but when combined with the Fukui function, it does. ABSTRACT Nanographenes, a subclass of polycyclic aromatic hydrocarbons (PAHs), have attracted significant interest due to their unique electronic properties and broad ...

Aromaticity‐Induced Spin State Switching and High‐Spin States in Non‐Alternant Polyradicals

open access: yesJournal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
The peculiar topology of some non‐alternant systems allows such a degree of freedom in favored spin‐alignment between unpaired electrons that the polyradical can be in low‐, intermediate‐, and high‐spin ground state. Thus, the modulation of resonance energy upon distortions of pro‐aromatic units via external stimuli may result in switching the lowest ...

Thrips responses to plant odours [PDF]

open access: yes
Thrips responses to plant odour compounds were assessed using a Y-tube olfactometer. Several compounds were attractive to adult Frankliniella occidentalis females, since the majority walked towards the odour source.

Enumeration of Matchings: Problems and Progress

open access: yes, 1999
This document is built around a list of thirty-two problems in enumeration of matchings, the first twenty of which were presented in a lecture at MSRI in the fall of 1996. I begin with a capsule history of the topic of enumeration of matchings.
