Assembly and Properties of Donor/Acceptor–Functionalized 2,6‐Bisethynylpyridines; Investigations of Through‐Bond and Through‐Space Charge Transfer Behavior

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 10, October 2026.
Introduction of a cation to donor/acceptor‐functionalized 2,6‐bisethynylpyridines results in through‐space interaction of donor and acceptor units. The electronic effects of this organization are explored using 1H‐NMR and UV‐vis spectroscopies. ABSTRACT Introduction of Ag(I) cations to 2,6‐bisethynylpyridine units decorated with electron‐donating (N,N ...

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

open access: yesRiver Research and Applications, Volume 42, Issue 8, Page 1736-1754, October 2026.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Photodegradation of Azo and Hydrazone Colourants on Cellulose‐Based Materials: A Mass Spectrometric Screening

open access: yesChemistrySelect, Volume 11, Issue 37, 6 October 2026.
Natural‐light ageing of early azo dyes and hydrazone pigments (AY36, AO7, and AR1) on cellulose‐based supports produces marked chromatic changes and distinct molecular transformations. LC–HRMS analysis of aged AY36 reveals degradation products associated with N‐oxidation, N‐dearylation, azo‐bond oxidation, and formaldehyde addition, providing a first ...

Patterns and Drivers of Mercury Accumulation in Croplands, a Meta‐Analysis

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Mercury (Hg) is a potent neurotoxin that poses risks to human and environmental health, particularly in regions influenced by anthropogenic Hg emissions. Although Hg emissions have declined across North America and Europe following regulatory controls and phase‐outs, emissions remain elevated in some regions due to activities such as artisanal

The Anatomy of a Dust Emitting Hot Spot: The White Sands Playa‐Aeolian System, New Mexico, USA

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract The White Sands aeolian system is a hot spot of dust emissions and has likely been a persistent dust source since the early to mid‐Holocene, when arid conditions promoted the desiccation and erosion of Pleistocene Lake Otero and the formation of the dune field.
