Synergistic Effects of Antioxidants on Tribological Properties of Lithium Grease with α-Zirconium Phosphate as Solid Lubricant

Lithium grease was prepared by using α-ZrP as solidlubricant and 2,6-di-tert-butyl-p-cresol (BHT) and diphenylamine (DPA) asantioxidants. The synergistic effects of the two antioxidants on thetribological properties of α-ZrP lithium grease were investigated on an SRVhigh frequency linear reciprocating tester and a four-ball tester separately.The abrasive surfaces were characterized by 3D optical profiler, scanningelectron microscope (SEM) and energy dispersive X-ray spectrometer (EDS).When the ...

Research of Mediator Microbial Fuel Cell Performance in Electricity Generation and Ammonia Nitrogen Removal

A three chamber microbial fuel cells(MFC),employingescherichia coli (E. coil) as anode catalyst, was designed. Its electricitygeneration and ammonia nitrogen removal were investigated in mediator-less, newmethylene blue (NMB)as mediator and neutral red (NR)as mediator conditions. Theresults show that mediators improved open circuit voltage(VOC)of MFC andreduced the time of reaching steady-state VOC. With NMB mediator, VOC of MFCachieved a stable value more easily. VOC of MFC with NR mediator was ...
