This paper studies the impact of collectivization on patricide in China during the Cultural Revolution. From 1955 to 1957, nearly 96 per cent of farmers were organized into communes. Consequently, fathers lost control over family wealth. We propose that this shift decreased fathers’ bargaining power over their adult sons, which might increase family conflicts. On the basis of a novel dataset, we find...
Cobalt (Co) is an efficient oxygen reduction reaction (ORR) catalyst but suffers from issues of easy deactivation and instability. Here, it shows that ZrO2 can stabilize Co through interface electron coupling and enables highly efficient 4e− ORR catalysis. Porous carbon nanofibers loaded with dispersed Co‐nanodots (≈10 nm, 9.63 wt%) and ZrO2 nanoparticles are synthesized as the catalyst. The electron...
