Spectroscopic Investigation of Polysulfide Redox Evolution in Catholyte Solutions for Potassium–Sulfur Batteries

open access: yesAdvanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

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

open access: yesAllergy, Volume 81, Issue 6, Page 1985-2000, June 2026.
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.

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Hydrotreatment of Nylon 66 and Amide Model Compounds Over Sulfided NiMo Catalysts

open access: yesChemCatChem, Volume 18, Issue 9, 14 May 2026.
Hydrotreatment of nylon‐66 and the model amide N,N‐dibutylhexanediamide over sulfided NiMo/Al2O3 reveals competing hydrodenitrogenation and hydrodeoxygenation pathways, without formation of heterocyclic products. Pathway selectivity is influenced by reaction conditions and differs between the model compound and the real nylon sample.

Polyethylene‐Polyamide‐6 Diblock Copolymers for Fused Filament Fabrication

open access: yesJournal of Polymer Science, Volume 64, Issue 8, Page 1744-1759, 15 April 2026.
Linear HDPE‐PA6 block copolymers were prepared by polymerization of ethylene to a macroinitiator and subsequent anionic caprolactam polymerization. The copolymer with a HDPE mass of 6500 Da and PA6 mass of 20.000 Da was used as a filament in 3D printing.

Inter‐Atomic Synergy on Single‐Atom Alloy Promotes Cyclohexanone Oxime Electrosynthesis

open access: yesAdvanced Materials, Volume 38, Issue 21, 13 April 2026.
Electrosynthesis of cyclohexanone oxime using renewable electricity offers a greener alternative to traditional energy‐intensive methods. Here, we develop a Fe1Bi single‐atom alloy that delivers 70.9% Faradaic efficiency and 0.94 mmol cm−2 h−1 yield rate through the atomic‐scale synergistic mechanism.
