Pressure–induced phase transitions of Zn₂SiO₄ III and IV studied using in–situ Raman spectroscopy

Phase transitions in porous media studied by NMR spectroscopy

Phase Transitions in Oxides Studied by Perturbed Angular Correlation Spectroscopy

Radioactive atoms located on cation sites in oxide matrices can be used to monitor phase transitions by measuring the electric or magnetic hyperfine interactions by means of Perturbed Angular Correlations spectroscopy. The article illustrates three types of phase transitions studied with 'in tracers and their daughter nuclei m C d , namely magnetic, structural and REDOX phase transitions in bin...

iii THERMAL METROLOGY OF POLYSILICON MEMS USING RAMAN SPECTROSCOPY

Kearney of Sandia National Laboratories for the opportunity to work on this project and experience the complete research process. Without their continuous guidance and financial support throughout the process, I would not have been able to achieve my goal of a graduate degree in mechanical engineering. In addition, I would like to thank Dr. Zhuomin Zhang for serving on the thesis reading commit...

Detection and Characterization of Human Teeth Caries Using 2D Correlation Raman Spectroscopy

Background: Carious lesions are formed by a complex process of chemical interaction between dental enamel and its environment. They can cause cavities and pain, and are expensive to fix. It is hard to characterize in vivo as a result of environment factors and remineralization by ions in the oral cavity. Objectives: The development of a technique that gives early diagnosis which is non-invasi...
