In order to solve the problem of insufficient carbon source for denitrification in sewage treatment plants (STPs), iron-dependent autotrophic denitrification was investigated. Combining the iron-dependent autotrophic denitrification and the microbial fuel cell (MFC) would not only be economical...

Properties of KTiOPO4Mx (M = K, Na, and Li, x = 0.000 to 1.000) as anodes for potassium-ion battery (PIB), sodium-ion battery (SIB), and lithium-ion battery (LIB) are investigated by density functional theory (DFT) calculations. Our work reveals that electrochemical performance of KTiOPO4 as an...
