In order to achieve a better understanding of the processes that occur during
formation and sintering of zirconia, various chemical and physical techniques were
used. Along with Perturbation Angular Correlation spectroscopy, that allowed us to
investigate microscopic properties inside the nanometer-size zirconia grains, such
techniques as Scanning Electron Microscopy and...
Several types of solid-state inorganic materials are prepared and characterized. By using the SILAR (Successive Ionic Layer Adsorption and Reaction) deposition method in conjunction with hydrothermal dehydration both low-temperature deposition and crystallization of oxide thin films are achieved. Various aspects of new transparent p-type materials are studied by examining both...
Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...
Nitrogen evolution during black liquor pyrolysis and black liquor combustion were studied using a laminar entrained-flow reactor. The experimental conditions were 700-1100°C and 0.3-2.2 seconds residence time. The pyrolysis experiments were performed in a pure nitrogen atmosphere. The oxygen concentrations during the combustion of black liquor experiments were 4 and...
The importance of two sources of NO formation, nitrogen in combustion air
and nitrogen in the fuel, during black liquor combustion was studied using a laminar
entrained flow reactor. Pyrolysis and combustion experiments were conducted in
nitrogen atmosphere and in a mixture of argon and helium in the composition 99%...
Metal oxide nanocrystals have attracted significant interests due to their unique chemical, physical, and electrical properties which depend on their size and structure. In this study, a continuous flow microreactor system was employed to synthesize metal oxide nanocrystals in aqueous solution. Assembly of nanocrystals is considered one of the most...
