Graded Solvation‐Structure Electrolyte for Synergistic Polysulfide Confinement and Interfacial Stabilization in Potassium‐Sulfur Batteries

open access: yesCarbon Energy, EarlyView.
A graded solvation structure is designed through a strongly–moderately–weakly solvating strategy to synergistically regulate potassium polysulfide dissolution and K‐anode deposition behavior. This tailored electrolyte effectively stabilizes the electrode/electrolyte interphases and accelerates sulfur redox kinetics.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

open access: yesChemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.
