Pourbaix sensors in polyurethane molecular logic-based coatings for early detection of corrosion
Autor: David C. Magri, Glenn J. Scerri, Jake C. Spiteri
Publikováno v: Materials Advances. 2:434-439
The cost of corrosion to the world economy is estimated to be in excess of US$2.5 trillion per year. Herein we present a strategy for the early detection of corrosion using purposely designed molecules with on-board parallel processing in a polyureth

Fluorescent Photoinduced Electron Transfer (PET) Logic Gates for Acidity (pH) and Redox Potential (pE)
Autor: Alex D. Johnson, Jake C. Spiteri, David C. Magri
Publikováno v: Journal of Fluorescence. 27:551-559
This mini-review highlights the photophysical properties of fluorescent molecular logic gates responsive to acids and oxidants, particularly those developed in our laboratory the past few years. The review pays tribute to earlier developments that la
