- Created Nitrogen Dip Probe or Pour-Fill Cryostat (part): "Carries the sample, its four contacts and a thermometer into the nitrogen bath to record resistance from room temperature to 77 K. A lab-built probe has a thin-wall stainless tube, copper sample block, spring pins, eight or more leads and a vent hole, and a bought cryostat holds the sample in vacuum."
