The synergistic cooperation electrooxidation and ultrasonication markedly accelerated reaction. This mechanistically different method is distinguished by its wide substrate scope transition-metal-free external-oxidant-free conditions, thus complementing existing metal-catalyzed or peroxide-mediated protocols for green synthesis...
Nickel (Ni) is an essential common environmental contaminant, it hazardous to male reproduction, but the precise mechanisms are still unknown. Blood-testis barrier (BTB), important testicular structure consisting of connections between sertoli cells, target reproductive toxicity caused by many toxins.
