Restoration ecology in conflict along the Colorado front range
Restoration Ecology, EarlyView.Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

Remediation Journal, Volume 36, Issue 2, Spring 2026.ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the

Flow‐Enabled Direct Photochemical Functionalization of Aryl Fluorides
Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.We report a simple, catalyst‐free method to activate strong carbon–fluorine bonds using UV light in flow. A 3D‐printed microreactor enables controlled irradiation, giving selective functionalization of fluoroarenes. The method forms CC and CP bonds, works on gram scale, and avoids additives or tailored catalysts.

Synthesis of Acyl Fluorides Using the Tribromoisocyanuric Acid (TBCA)/Triphenylphosphine/HF.Pyridine
Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.The present contribution reports an efficient Appel‐type reaction for the synthesis of acyl fluorides from their corresponding carboxylic acids using the tribromoisocyanuric acid/triphenylphosphine/HF.pyridine system in up to 69% isolated yields. The methodology tolerates a variety of carboxylic acids. The usefulness of our methodology was demonstrated

Fluorinative Olefin Bond Functionalization of Selected Functionalized Cycloalkenes
Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.Palladium‐catalyzed ring olefin bond difunctionalization, through functional group and substrate‐dependent arylfluorination, of selected functionalized cycloalkenes has been studied. Palladium‐catalyzed ring olefin bond difunctionalization through arylfluorination of selected five‐, six‐, and seven‐membered functionalized cycloalkenes has been studied.
