Using a graphene field-effect transistor biosensor, we monitored the pH inside a living biofilm
with fast temporal resolution (~ 1 s) over multi-hour time periods. The atomically-thin sensor is
positioned between the biofilm and a supporting silicon oxide surface, providing non-invasive
access to conditions at the base of the biofilm....

A year-long, bench-scale treatability study was performed to assess whether an activated sludge sequencing batch reactor could be used to treat an influent stream of 50/50 (v/v) municipal wastewater and landfill leachate to discharge standards established by the Oregon Department of Environmental Quality. One primary obstacle that was exposed during...
