An Instrument for Isomer‐Specific Action Spectroscopy of Charged Clusters: Electronic Spectra of C 14 + and Ca@C 60 +

open access: yesChemistry–Methods, Volume 6, Issue 8, August 2026.
Disentangling spectral congestion of a mixture of isomers in gas‐phase spectroscopy is critical. We present an instrument combining ion mobility, mass spectrometry, and spectroscopy in a cryogenic 3D Paul trap to investigate the isomer‐specific charged clusters and illustrate its performance with the electronic spectra of C14+ and Ca@C60+. Interpreting

Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, Volume 8, Issue 8, August 2026.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

A study of extended red emission in reflection nebulae [PDF]

open access: yes, 1994
In the first part of this thesis spectroscopic observations of the Red Rectangle nebula are presented. A link is made between the most prominent unique emission line features, which are superimposed on the broad emission spectrum of the Red Rectangle ...

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

An Ultrafast Time Resolved Infrared and Computational Study of the Photochemistry of Ethyl 2‐Diazo‐3,3,3‐Trifluoropropanoate (CF3CN2CO2Et)

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 8, August 2026.
The photochemistry of ethyl 2‐diazo‐3,3,3‐trifluoropropanoate shows that its excited singlet state undergoes internal conversion, carbene formation, and diazirine formation. The resulting singlet carbene reacts through solvent‐dependent pathways, forming ylides in methanol and acetonitrile or a C–Cl insertion product in chloroform.

Widespread Increase in Global Plant Water Stress Obscured by Greening

open access: yesAGU Advances, Volume 7, Issue 4, August 2026.
Abstract Understanding the vulnerability of plants to more severe and frequent drought events and developing adaptive management strategies requires robust methods for quantifying long‐term changes in plant water stress (PWS). Most data‐driven explorations of long‐term trends in PWS have focused on alterations in canopy structure (e.g., leaf area index)
