Study of the thermal resistance of alpha-phase aluminum oxide (alpha-Al2O3) films deposited on the paper substrate
(Elsevier B.V., 2014-08-01)
The purpose of this study was to increase the thermal resistance of a cellulose substrate, using films (a mixture of corundum-phase aluminum oxide, (x-Al2O3, and a PVA solution). The corundum phase, which was chosen due ...
Insights into palladium deactivation during advanced oxidation processes
(2022)
A key step in creating efficient and long-lasting catalysts is understanding their deactivation mechanism(s). On this basis, the behavior of a series of Pd/corundum materials during several hydrogen adsorption/desorption ...
