Selective, Oxygen‐Tunable, and Metal‐Free Functionalization of Polyethylene Through Dual‐Mode Nitrosation and Carbonylation

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
A metal‐free nitrosation process enables direct C–H functionalization of polyethylene (PE) with high selectivity, producing either oxime‐ or carbonyl‐functionalized polymers. Using t‐BuONO under visible light or thermal conditions, the process operates in both lab‐scale and industrial settings.

Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side

open access: yesAllergy, EarlyView.
ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.
