Vacuum treatment to stabilize oxidation at low temperature region in porous silicon
(2020)
Oxidation in porous silicon is studied for as-etched samples and samples subjected to high vacuum at room temperature. Attenuated Total Reflectance (ATR) measurements in infrared spectroscopy for temperatures ranging from ...
High temperature cyclic oxidation behavior of a low manganese Fe12Mn9Cr5Si4Ni-NbC shape memory stainless steels
(2021-03-15)
High amounts of Mn in Fe-Mn-Si-Cr-Ni shape memory stainless steels are detrimental for oxidation resistance at high temperatures. However, in order to maintain the shape memory effect of these alloys the content of manganese ...
SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...

Kinetics of low-temperature CO oxidation on Au(111)
(Elsevier Science, 2015-12-22)
The oxidation of carbon monoxide on oxygen-modified Au(111) surfaces is studied using a combination of reflection-absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD). TPD reveals that CO ...
Effect of the preparation method and calcination temperature on the oxidation activity of CO at low temperature on CuO–CeO2/SiO2 catalysts
(2013)
The effect of preparation method, either coimpregnation or sequential impregnation, and of calcination temperature (between 500 degrees C and 700 degrees C) of CuO-CeO2/SiO2 catalysts on the CuO-CeO2 interface and on their ...
