New high performance Janus electrode for rechargeable Na-S batteries

Green Car Congress

containing both cathode and anode properties in the same body—for sodium-sulfur (Na-S) batteries by adopting a metal-organic framework (MOF) to incorporate single Yttrium atoms in a nitrogen-doped rhombododecahedron carbon host (Y SAs/NC). Researchers in China have designed a high-performance Janus electrode—i.e., 2c07655.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.
