A Shear Thickening Colloidal Suspension Functioning via Progressive Impact Jamming with Persistent Lubrication Layer

Advanced Science, EarlyView.
An ionic liquid‐based shear‐thickening fluid (ILSTF) exhibits lubricated dynamics from strong shear thickening to impact‐triggered jamming. A persistent nanometric solvation layer around silica governs both the shear thickening saturation in rheology and jamming front propagation under dynamic impact compression.

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling

Angewandte Chemie, EarlyView.
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

Synergistic Hydrogen‐Bonding and Covalent Crosslinking in Polybenzimidazole Membranes for Wide‐Temperature Anhydrous Fuel Cells

Advanced Science, EarlyView.
A dual‐network architecture combining a thermally reinforced hydrogen‐bonding matrix with an amine‐anhydride covalent framework was constructed in Tröger's Base (TB)‐functionalized polybenzimidazoles. This design yielded the TBAm‐PBI‐TB membrane with high acid uptake (469.5%), anhydrous conductivity (264.7 mS cm−1), and robust stability.

Evaluation of greener solvents for solid-phase peptide synthesis

Green Chemistry Letters and Reviews, 2021
Polar aprotic solvents such as N,N-Dimethylformamide (DMF), N-methyl-2-pyrrolidone (NMP), N,N’-dimethylacetamide (DMAc) and chlorinated solvent such dichloromethane (DCM) are the most widely used solvents for Fmoc solid-phase peptide synthesis (SPPS ...

Enhancing Interfacial Dioxygen Bridging Dynamics of Waste‐Derived Cathode Catalysts for Augmented High‐Rate Performance in Li‐O2 Batteries

Advanced Science, EarlyView.
This study fabricates Fine Slag/Ti4O7@TiC hybrids with interfacial dioxygen bridge coupling to optimize oxygen redox dynamics in lithium‐oxygen batteries (LOBs). Lattice distortion from oxygen vacancies and inherent charge repulsion of Ti‐O‐C interfacial coupling reconstruct and refine the surface coordination environment.

Redox Oligomer Assembling Hierarchical Reinforced Framework Cathodes for Ultra‐Stable High‐Performance Zinc‐Ion Batteries

Advanced Science, EarlyView.
Redox phenoxoline‐benzoquinone oligomer has been designed as reinforced concrete framework like freestanding cathodes for high‐performance ZIBs. An optimal specific capacity of 339.5 mAh g−1 was contributed with exceptional retention of 87.5% after 65 000 cycles at 10 A g−1. Flexible energy storage is also demostrated.

Improving the Long-Range Intramolecular Proton Transfer—Further Molecular Design of the Successful Molecular Switch 8-(Benzo[d]thiazol-2-yl)quinolin-7-ol (HQBT)

Molecules
Previously, we have described a successful molecular switch (8-(benzo[d]thiazol-2-yl)quinolin-7-ol), working on the basis of long-range proton transfer. Bearing in mind that its switching efficiency in low-polarity aprotic solvents is not sufficient, in ...
