Lifetime Testing of Wire-Grid Polarizers with Selected Over-Coatings
… Over-coating a WGP has been found to increase lifetime and durability. This research provides lifetime data on coated and uncoated WGPs. WGPs over-coated with 100nm of SiO2, 300nm of MgF2, and with no over-coating were heated to temperatures of 450 ºC, 500 ºC, and 550 ºC and timed until they …

Mechanics and multi-physics deformation behavior of polymer electrolyte membranes
… and mechanical degradation over the target lifetime of the fuel cell. Membrane mechanical integrity is thus a critical concern for commercial distribution of PEMFC technology. This thesis has two primary focus areas: (1) characterization and modeling of Nafion, the benchmark PEM, in order to …
