Calibration of the Scanning Kelvin Probe By Applied External Potential

Autor: Ronald Anthony Zeszut, Douglas C Hansen

Publikováno v: ECS Meeting Abstracts. :778-778

The scanning Kelvin probe (SKP) is a device that measures the difference in work function between a sample and probe tip on the instrument, and has proven to be a useful research tool over the past several decades. With this technique, the Volta pote

Predicting Atmospheric Corrosion of Aluminum 2024 Coupons in Coastal Environments with Data Analytics

Autor: Christopher D. Taylor, Douglas C Hansen, David Borth, Christine Sanders

Publikováno v: ECS Meeting Abstracts. :713-713

How can we design short-term laboratory corrosion tests to adequately simulate long-term outdoor atmospheric corrosion? To achieve this objective, models need to be devised to rank and quantify critical environmental variables that influence atmosphe

Inhibition of flash rusting of HY80 by a mussel adhesive protein: Characterizing the interaction of MeFP-5 with a high strength low alloy steel

Autor: Brooke N Bennett, Kathryn R. Zimlich, Douglas C. Hansen

Publikováno v: Electrochimica Acta. 301:411-420

A proteinaceous biopolymer, mussel adhesive protein #5 (MeFP-5), isolated from the common blue mussel (Mytilus edulis L) has been investigated as a model for designing an aqueously soluble candidate corrosion inhibitor system that is non-toxic and en
