Raman Spectroscopic Investigation Of The Speciation Of Uranyl (Vi) And Thorium (Iv) Ions In Chloride-Bearing Aqueous Solutions Under Hydrothermal Conditions, Nadib Akram
MSU Graduate Theses
Raman spectra were acquired for a uranyl chloride aqueous solution at temperatures ranging from 25°C to 500°C at the chloride concentration of 6M and uranium (vi) concentration of 0.05M. The measurements were taken by sealing the sample in a hydrothermal diamond anvil cell (HDAC) which enabled spectra acquisition at non-ambient conditions. The pressure inside the cell was measured by estimating the liquid-vapor homogenization temperature (TH) and using the isochoric equation of state diagram of water. The acquired spectra were then fitted to determine the speciation distribution of the various uranyl chloride species for the mentioned concentration. The developed …

Synthesis And Characterization Of Carbon Coated Barium Titanate Core-Shell Nanoparticles, Moudip Nandi
MSU Graduate Theses
Core-shell nanoparticles (CSNP) with fascinating ferroelectric properties have diverse applications in biotechnology and the electronic field of studies. Among so many perovskites, barium titanate (BTO) nanoparticles draw much interest due to their distinct electronic and ferroelectric features. Additionally, the incorporation of carbon in the shell of CSNP makes it suitable for application in many fields due to its innocuous nature. Carbon not only increases the biocompatible properties of an element but also gives mechanical stability to the CSNP. This thesis is targeted towards the synthesis of oxide-carbide CSNP, where the core is made of BTO and the shell is made …
