Open AccessDMT1-dependent endosome-mitochondria interactions regulate mitochondrial iron translocation and metastatic outgrowth
Transient early endosome (EE)-mitochondria interactions can mediate mitochondrial iron translocation, but the associated mechanisms are still elusive. We showed that Divalent Metal Transporter 1 (DMT1) sustain...

Mechanism of mediated alkali peroxide oxidation and triplet versus singlet oxygen formation
Aprotic alkali metal–O2 batteries face two major obstacles to their chemistry occurring efficiently, the insulating nature of the formed alkali superoxides/peroxides and parasitic reactions that are caused by the...

Singlet oxygen generation as a major cause for parasitic reactions during cycling of aprotic lithium–oxygen batteries
Non-aqueous metal–oxygen batteries depend critically on the reversible formation/decomposition of metal oxides on cycling. Irreversible parasitic reactions cause poor rechargeability, efficiency, and cycle lif...
