Congrats to recent-PhD-grad Shiheng Lu and PhD-candidate Brittany Smith on leading our latest advancement in printed, carbon-based electronics! Print processes typically rely on hazardous chemicals to remove unwanted residue and/or properly suspend materials -- particularly nanomaterials. In this work, thin-film transistors are printed on paper substrates using nothing but water. The work is reported in the journal Nano Letters and is receiving media attention!
