Wet thermal oxidation at 1000 “C of a 470-nm-thick epitaxial Ge~&3,,~ layer on ( 100)Si produces oxides of different composition depending on the details of the oxidation procedure. When a cold sample is directly exposed to the hot steam, the surface layer of the oxide contains both Ge and Si. Only SiOZ forms if a preheated sample is exposed to the hot steam. The effect is not present for dry o...

The fullerenes, carbon nanotubes, and graphene have enriched the family of carbon allotropes over the last few decades. Synthetic carbon allotropes (SCAs) have attracted chemists, physicists, and materials scientists because of the sheer multitude of their aesthetically pleasing structures and, more so, because of their outstanding and often unprecedented properties. They consist of fully conju...

The catalytic wet oxidation process was used to study the degradation of carbohydrates in wastewater with glucose as a model compound. transition metals Co and Mo were transformed into their insoluble metal oxide forms, Co3O4 MoO3. A novel catalyst prepared by using CuNiIn alloy, which oxidized at 700 °C generate an mixed oxide. Wet reactions performed 150–210 for 60 min 20 bar O2 pressure. per...
