Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Cyclodextrins as Chiral Selectors in Capillary Electrophoresis—Recent Developments in Understanding Analyte Complexation and Applications in Pharmaceutical Analysis

open access: yesELECTROPHORESIS, EarlyView.
Cyclodextrins are the most often applied chiral selectors in CE enantioseparations. In combination with NMR spectroscopy and molecular modeling, studies for an understanding of chiral recognition underlying enantioseparations have been performed.

On the Structural Evolution Mechanism of Lignin‐Derived Hard Carbon for Refining Sodium‐Ion Storage

open access: yesElectron, EarlyView.
The lignin‐derived hard carbons with different microstructures were prepared under different carbonization temperature (600°C–1600°C) and carbonization time (0–6 h). The correlation between the local structure of all hard carbons and sodium‐ion storage performance was statistically analyzed. The optimized hard carbon anode has high‐rate performance and

Should multinationals care about development? Rethinking global strategy in an unequal world

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary While multinational corporations (MNCs) can profoundly shape global development trajectories, global strategy research has largely treated development as peripheral to core strategic concerns. This Perspective paper examines the contested relationship between global strategy and development, arguing that MNCs are neither ...
