FeO-doped mesoporous carbon cathode with a plumber's nightmare structure for high-performance Li-S batteries.

Shuttling of lithium polysulfides and slow redox kinetics seriously limit the rate and cycling performance of lithium-sulfur batteries. In this study, FeO-dopped carbon cubosomes with a plumber's nightmare structure (SP-FeO-C) are prepared as sulfur hosts to construct cathodes with high rate capability and long cycling life for Li-S batteries. Their three-dimensional continuous mesochannels and carbon frameworks, along with the uniformly distributed FeO particles, enable smooth mass/electron transport, strong polysulfides capture capability, and fast catalytic conversion of the sulfur species.

Geniposide attenuates cadmium‑induced oxidative stress injury via Nrf2 signaling in osteoblasts.

Geniposide, as a type of iridoid glycoside, has antioxidative capacity. However, the mechanism underlying the effect of geniposide in cadmium (Cd)‑induced osteoblast injury remains only partly elucidated. In the present study, Cell Counting Kit‑8 (CCK‑8) was used to determine MC‑3T3‑E1 cell viability.
