Carbon Energy, EarlyView.Origin of the ultrahigh‐rate charge capability of FeS2: FeS2 demonstrates exceptional high‐rate charging capability, delivering 92% capacity retention at 10 C and maintaining as much as 60% capacity retention even at 30 C. This originates from an ultrahigh apparent diffusion coefficient involving both Li+ and Fe2+.

Evolution of the water cluster in pore condensation
Droplet, EarlyView.In pore condensation, lower contact angles reduce molecular displacement (60%) and potential energy (10%), enhancing vapor capture tenfold. Pores restrict water molecule mobility, promoting condensation. On hydrophobic surfaces (124∘$^\circ$), pores stabilize embryos, ensuring uniform condensation within pores, boosting nucleation efficiency.
