Progress and perspectives on electrocatalysis in room-temperature Na-S batteries.

Room-temperature sodium-sulfur (RT Na-S) batteries that typically feature multielectron conversion chemistries can allow an ultrahigh specific capacity of 1675 mA h g and a high energy density of 1275 W h kg but unfortunately suffer from a lot of intractable challenges from sulfur cathodes. These issues cover the poor electronic conductivity of pristine sulfur and solid products, the severe shuttle effect of polysulfides, and the sluggish redox kinetics, The shuttling behavior of polysulfides always leads to cathode/anode instability and performance degeneration. Recently, the emerging catalysis strategy has been demonstrated as a reliable pathway to tackle the central issues caused by sulfur electrochemistry and revitalize RT Na-S batteries.

Entangling gates on degenerate spin qubits dressed by a global field.

Semiconductor spin qubits represent a promising platform for future large-scale quantum computers owing to their excellent qubit performance, as well as the ability to leverage the mature semiconductor manufacturing industry for scaling up.
