Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Spin-orbit effects in a triple quantum dot shuttle [PDF]

Physical Review B, 2013
Spin transport properties of a triple quantum dot shuttle system are analyzed in the presence of spin-orbit interaction. We calculate the spin current through the device as a function of the bias voltage detuning. We find that new resonances in the current through the shuttle appear due to the presence of spin-orbit interaction, and the states involved
