Elastic, strong and tough ionically conductive elastomers.

Stretchable elastic materials with high strength, toughness, and good ionic conductivity are highly desirable for wearable devices and stretchable batteries. Unfortunately, limited success has been reported to attain all of these properties simultaneously. Here, we report a family of ionically conductive elastomers (ICEs) without compromise between mechanical properties (high stiffness, reversible elasticity, fracture resistance) and ionic conductivity, by introducing a multiple network elastomer (MNE) architecture into a low polymer.

NaLiMO(CO) (M = W and Mo): An Alternative Electrolyte for High-Temperature Electrochemical Cells.

Two new acentric oxycarbonates NaLiMO(CO) (M = W and Mo) were synthesized via a conventional solid-state route. Their structure was determined from X-ray diffraction data on single crystals. NaLiMO(CO) (M = W and Mo) crystallizes in the acentric cubic -43 space group ( ≈ 7.

Using the CAESARE tool in fetal heart rate analysis.

Background: To evaluate the theoretical impact of the CAESARE decision-making tool (which is based on fetal heart rate) on the rate of cesarean section deliveries and the prevention of metabolic acidosis risk.

Methods: We conducted an observational, multicenter, retrospective study of all patients from 2018 to 2020 who had a cesarean section at term due to non-reassuring fetal status (NRFS) during labor. Primary outcome criteria were the rate of cesarean section births observed retrospectively compared to the theoretical rate by the CAESARE tool.
