Anisotropic NMR as a Crucial Tool for Differentiation of Epimers With High Conformational Flexibility

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Epimer discrimination remains challenging due to subtle NMR differences. Here, we propose a methodology based on 13C‐RCSA and RDC anisotropic parameters, enabling the assignment of two flexible tetraprenyltoluquinol epimers (1a and 1b) with remote stereoclusters.

The Bureaucratic Paradox of Citizen Agency: Institutional Crowding‐Out in Government‐Catalyzed Co‐Production in Shanghai, China

open access: yesGovernance, Volume 39, Issue 4, December 2026.
ABSTRACT Public service co‐production is often framed as a means of creating public value, yet its dynamics are complex when citizen‐led participation is catalyzed by strong public institutions. This mixed‐methods study examines government‐catalyzed, citizen‐centric co‐production in Shanghai, China, where the state provides institutional support ...
