Hydrogen Halide Gas Sensors: Active Materials, Operation Principles, and Emerging Technologies
Interdisciplinary Materials, EarlyView.This review considers hydrogen halide (HX) gas sensors across functional materials and principles: acoustic, chemical, optical and nanophotonic. The strong acidity and reactivity of HX gases are discussed as constraints for stability and selectivity of these devices.

iMetaOmics, EarlyView.First use of a natural swine model with lipid metabolism to directly link lipid differences to a quantifiable intestinal villus height phenotype. Identified the phospholipid‐derived oleoylethanolamide, rather than canonical fatty acids, as the endogenous primary ligand that activates peroxisome proliferator‐activated receptors α (PPARα) to enlarge ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

FeCl3‐Catalyzed Synthesis of Ynones from Silylated Alkynes and Acetic Anhydride
ChemistryOpen, EarlyView.The synthesis of alkynones from silylated alkynes and acid chlorides, first reported by Birkhofer in 1963, remains a valuable transformation. However, its reliance on stoichiometric AlCl3 and corrosive reagents raises environmental and practical concerns. To address this, a greener protocol using catalytic FeCl3 and acetic anhydride is developed.

Journal of Polymer Science, EarlyView.Polyester with the structure of 2‐thioethyl ester reveals oxidative degradability via the oxidation to sulfone followed by base‐promoted β‐elimination. Since the degradation occurs by the nonnatural stimuli, these polymers are stable during use but can be degraded at the desired instant after use.
