Growth and investigations of certain oxide crystals exibhiting phase transitions
A simple and efficient procedure has been devised to separate the grown YBa?Cu?O?.? crystals from the flux matrix. The extracted YBCO crystals have clear surfaces free from flux. Thermal shock and consequent cracking of ... -
Studies on thermal expansion of irradiated polymers from 10K to 340K
Thermal expansion is due to anharmonicity in the interatomic potential of a solid. Thermal expansion depends on the types of interaction between the constituent atoms/molecules. It is small for covalently bonded materials ... -
Nonlinear propagation of intense electromagnetic waves in quasar and pulsar plasmas
his thesis presents the results of analytical as well as numerical investigations of radiation–plasma interaction instabilities in astrophysical plasmas. It consists of two introductory chapters, four main chapters, and ... -
Oriented molecules theoretical studies on mixed liquid crystals of opposite crystal
The thesis consists of two parts. Part I describes theoretical studies in mixed liquid crystals of opposite diamagnetic anisotropies. Part II deals with experimental NMR studies in single and mixed liquid crystals of ... -
Vibrational Spectroscopic and Dielectric Studies of some Ferroic Crystals
The polarized Raman spectra of LCS are studied in the room temperature orthorhombic and the low temperature monoclinic phases. The observed Raman lines are assigned in the C(aa)B setting. The polarized spectra agree well ... -
Ring-chain tautomerism and related studies
The thesis is entitled “Ring-Chain Tautomerism and Related Studies” and is divided into three parts. Part I consists of two chapters. Part I Chapter I consists of a review on tautomerism containing: A historical outline, A ... -
Synthesis of polycyclic compounds
The thesis entitled “Synthesis of Polycyclic Compounds” is divided into two sections, A and B. Section A comprises two chapters. Chapter I is a review of the benzhydrindane approach for the total synthesis of steroids. ...
