Sustainable and Simple Water‐Induced Separation of Ionic Liquid Mixtures
Angewandte Chemie, EarlyView.The cover image illustrates an innovative method for recovering ionic liquids (ILs) from their mixtures. This approach enables the recovery of over 99% of the IL by simply adding water–abundant, and safe solvent–under mild conditions, all while preserving the integrity of the ILs.

A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces
Asian Journal of Organic Chemistry, EarlyView.This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Hydrogenation of “Readily Activated Molecule” for Glycine Electrosynthesis
Angewandte Chemie, EarlyView.By recognizing the unique characteristics of the glyoxylate oxime intermediate, we introduce a brand‐new concept of “readily activated molecule”, which empowers Ag as the ideal catalyst for glycine electrosynthesis. Abstract The hydrogenation of glyoxylate oxime is the energy‐intensive step in glycine electrosynthesis. To date, there has been a lack of

MiR‐221‐3p Attenuates IL‐33‐Induced Mast Cell Cytokine Expression by Targeting KIT
International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Mast cells (MCs) are involved in type 2 inflammation in chronic rhinosinusitis with nasal polyps (CRSwNP), which depends on interleukin (IL)‐33 stimulation. MiR‐221 is reported to be an important regulator of MCs, and miR‐221‐3p can be expressed in CRSwNP. However, the role of miR‐221‐3p in CRSwNP is unclear. Methods Ethmoid tissues
