This week in Dr. Fiser’s lab

This week we used a potentiostat to create arrays of nickel tubes ten microns long and approximately 600 nm in diameter. The potentiostat sends a current through a solution of nickel ions, causing the ions to travel into a template with cylindrical pores, creating the tubes. We analyzed these tubes using the scanning electron microscope (SEM) at the Joint School of Nanoscience and Nanoengineering (JSNN). If we deposit nickel for too long in our potentiostat, the pores become overfilled, creating mushroom shapes rather than tubes.
