Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: 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...

A microscopic study of the interaction between aliovalent dopants and native defects in group IV oxides : indium and cadmium in ceria and zirconia

Creator:: Zacate, Matthew O.
Abstract:: In order to understand better the defect structure and dynamics associated with lower valent dopants complexed with native defects in group IV oxides, In/Cd perturbed angular correlation spectroscopy was performed in ceria and zirconia. Examining the orientation symmetry axis of defects in ceria single crystals at low temperature has allowed...

PAC studies of indium doped cerium oxide

Creator:: Shank, Karl
Abstract:: Perturbed Angular Correlation Spectroscopy (PAC) is a highly sensitive local probe technique well suited for studying defect characteristics of solids. This technique is applied to the problem of studying the solubility of indium in cerium oxide. Through the measurement of samples with differing levels in indium doping, the solubility of...

The problem of aftereffects in perturbed angular correlation studies of ceria

Creator:: Dundon, Lisa
Abstract:: Perturbed Angular Correlations (PAC) spectroscopy is an effective local probe technique often employed in the characterization of defects or phase transitions in any of a variety of materials. This technique relies upon the ability of probe nuclei to function as gauges of the magnetic fields and electric field gradients local...

Factors influencing the crystallization, phase and oxygen vacancy concentration in zirconia

Creator:: Karapetrova, Euguenia
Abstract:: 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...

Synthesis and study of oxides and chalcogenides : thin films and crystals

Creator:: Park, Sangmoon
Abstract:: 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...
