Heterostructured Sn:SnO2 nanodots decorated on reduced graphene oxide can simultaneously enhance conversion kinetics and inhibit dendrite growth, enabling stable lithium–sulfur batteries. Abstract The practical application of lithium–sulfur batteries is limited by polysulfide shuttling and sluggish reaction kinetics at the cathode, as well as ...

A novel descriptor and a bottom‐up design principle are established to enable the rational design of hydrogen storage materials based on d‐block transition metal single‐atom COFs. By modulating H₂ adsorption through d‐orbital tuning, this approach achieves both high storage capacity and fast kinetics, while revealing a volcano‐type relationship between
