Snow Gum Dieback Enhances Trunk Monoterpene Emissions in the Australian Alps
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Canopy decline is increasingly prevalent in high‐elevation snow gum (Eucalyptus pauciflora) forests across the Australian Alps. This phenomenon, known as snow gum dieback, is associated with infestations by the wood‐boring beetle, Phoracantha mastersi.

Functional Ecology, Volume 40, Issue 6, Page 1862-1877, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.Tetracene and bis(tri(isopropyl)silylethynyl)tetracene (TIPS‐tetracene) exhibit characteristic similarities and differences in their electrochemical redox behavior depending on the base solvent of the electrolyte. Analysis of cyclic voltammograms allows the quantification of substituent and solvent effects and the calculation of an “electrochemical gap.

Flavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Food Science &Nutrition, Volume 14, Issue 5, May 2026.Oxalis corniculata L. ethanol extract (OCEE) showed efficacy in promoting fracture healing. A total of 549 compounds were identified by UHPLC‐Q‐Exactive‐MS/MS, with three key components recognized. OCEE may accelerate fracture healing by regulating TNFα, MMP9, ESR1, TP53, and related signaling pathways. ABSTRACT Oxalis corniculata L.

Why is phenanthrene more stable than anthracene?
Macedonian Journal of Chemistry and Chemical Engineering, 2007 By means of a recently developed molecular-orbital-based method it is possible to estimate the energy effects of individual cycles, as well as pairs, triplets, etc. of cycles in polycyclic conjugated molecules.

Journal 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 ...

Unusual conjugation pattern in a class of benzenoid hydrocarbons [PDF]
, 1996 87-92Cyclic conjugation in angulenes (=unbranched catacondensed benzenoid hydrocarbons with one kink) has been examined. When moving along the hexagons of the angulene molecule cyclic conjugation varies in a rather non-uniform manner.
