Atmospheric Chemistry of CF3C(Cl)═CH2 (HCFO‐1233xf)

International Journal of Chemical Kinetics, Volume 58, Issue 11, Page 943-953, November 2026.
ABSTRACT 2‐chloro‐3,3,3‐trifluoropropene, CF3C(Cl)═CH2 (HCFO‐1233xf), is a volatile hydrochlorofluoroolefin, commonly used in industrial synthesis of other halogenated olefins. Kinetics and reaction mechanisms for the reactions of OH radicals, Cl atoms, and O3 with CF3C(Cl)═CH2 were investigated using FTIR/smog chamber studies in 700 Torr of air/N2 ...

Seasonal Shifts in Nitrogen Isotope Fractionation Regimes in the Leighton Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Nitrogen isotopes are used to trace nitrogen oxides (NOx = nitric oxide (NO) + nitrogen dioxide (NO2)) emissions and nitrate formation, but their interpretation depends on isotope redistribution during NO−NO2 cycling. A key uncertainty is whether this partitioning is controlled by equilibrium exchange or Leighton cycle.

Sulfur Dioxide Point Sources Remain Important for Daytime Plume‐Scale New Particle Formation in the United States: Case Study for Gary, Indiana During the Summer 2023 AEROMMA Aircraft Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Plumes from sulfur dioxide (SO2) point sources have been shown to be significant contributors to new particle formation (NPF), but SO2 emissions in the United States (US) have decreased drastically by ∼10× since the early 2000s. We present observations of plume‐scale NPF from SO2 point sources over the industrial hub in Gary, Indiana and ...

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐
