Delicate design of lithium‐ion bridges in hybrid solid electrolyte for wide‐temperature adaptive solid‐state lithium metal batteries

open access: yesInfoMat, Volume 8, Issue 3, March 2026.
A well‐designed hybrid solid electrolyte with stable lithium‐ion bridges via chemical linkages across the ceramic electrolyte phase and the polymer chain has been developed. This easily scale‐up hybrid solid‐state electrolyte with superior electrochemical properties withstands extreme operational challenges, that is, high‐rate cycling (4 C) and wide ...

Wireless Electromechanical Fluorophore Release From Soft Polymer Actuators

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 3, March 2026.
Simultaneous wireless electromechanical deformation and fluorescence emission of a polypyrrole‐based composite incorporating a π‐conjugated fluorophore (2’,7’‐bis([2,2’‐bithiophen]‐5‐yl)fluorene) allows mapping of electroactivity via a dual dynamic/light‐emitting readout.

Regioselectivity and the Nature of the Reaction Mechanism in Nucleophilic Substitution Reactions of 2,4-Dinitrophenyl X-Substituted Benzenesulfonates with Primary Amines

open access: yes, 2016
Second-order rate constants have been measured for the reaction of 2,4-dinitrophenyl X-substituted benzenesulfonates with a series of primary amines. The nucleophilic substitution reaction proceeds through competitive S−O and C−O bond fission pathways ...

5-Formyl-2-methoxyphenyl benzenesulfonate

open access: yesActa Crystallographica Section E Structure Reports Online, 2006
In the title compound, C14H12O5S, the isovanillin group makes a dihedral angle of 37.45 (15)° with the phenyl ring. The crystal packing is stabilized by a weak non-classical inter­molecular C—H⋯O hydrogen bond that links mol­ecules into a chain.

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 5, 2 February 2026.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

A Reactive Antagonist Strategy: Cysteine‐Directed Covalent Molecular Glue in Plant Hormone Receptor Regulation

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
The plant hormone jasmonate is perceived by COI1‐JAZ co‐receptors comprising a single F‐box protein COI1 and multiple JAZ repressors with overlapping functions, complicating genetic analysis. We present a reactive antagonist (RA) strategy that selectively promotes COI1 binding to a cysteine‐engineered JAZ variant while blocking wild‐type JAZs, enabling
