Quantum Zeno effect in the Cooper-pair transport through a double-island Josephson system

, 2003
Motivated by recent experiments, we analyze transport of Cooper pairs through a double-island Josephson qubit. At low bias in a certain range of gate voltages coherent superpositions of charge states play a crucial role.

Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

Environmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...
