Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Evidence for the benefit of prenatal pelvimetry in breech presentation at term: A low intertuberous distance is associated with assisted head delivery and short‐term neonatal morbidity

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Guidelines on vaginal breech delivery have several restrictions concerning feto‐maternal parameters. To date, they neglect the impact of prenatal pelvimetry, especially of the intertuberous distance (ITD), in nulliparous women attempting vaginal breech birth.
