High energy-density electrochemical flow capacitor
PAGE TITLE Overview PAGE SUMMARY Traditional flow batteries suffer from slow response rates due to faradaic reactions at the electrode-electrolyte surface and have limited cycle lifetimes (<12,000 cycles) which is a critical factor for grid scale energy storage. In contrast, the electrochemical flow capacitor is a rechargeable electrochemical...

Bi-Conductive Surfaces for Boiling Enhancement
PAGE TITLEOverviewPAGE SUMMARY We report the counterintuitive mechanism of increasing boiling heat transfer by incorporating low-conductivity materials at the interface between the surface and fluid. By embedding an array of non-conductive lines into a high-conductivity substrate, in-plane variations in the local surface temperature are created. During...
