Synthesis, Structure, and Properties of Inorganic Oxides
A wide variety of oxide materials (based on rock salt, spinel, corundum, perovskite, garnet, and pyrochlore) have highly adaptable structures, and their properties can easily be modified by suitable substitutions at various ... -
Disulphonamides of aryl and aralkyl disubstituted amines and hydrazines
The present thesis consists of four parts. They deal with the synthesis of the disulphonamides of diphenylamine, phenylbenzylamine, dibenzylamine, diphenylhydrazine and dibenzylhydrazine and their starting materials. Part ... -
Studies in sulphanilamides
The present thesis consists of three parts (each part being divided into further sub-sections) preceded by a General introductory article on “Sulphonamides”. Under the heading of “Sulphonamides” various aspects of problems ... -
Isolation of anthracene phenanthrene and carbazole from anthracene oil from Indian source
Anthracene oil was first distilled in a single lot up to 360°C, and the total quantity of solids that separated out on cooling at ordinary temperature (room temperature), and on cooling at 0°C for a week and for a month ... -
On new sulphanilamide drugs : N1-substituted sulphanilamide derivatives of S-alkylisothioureas and S-alkylisothiosemicarbazides
The present thesis consists of three parts, all of them dealing generally with synthetic drugs consisting of N?-substituted sulphanilamide derivatives of S-alkyl-isothioureas and S-alkyl-isothiosemicarbazides. Part I This ... -
Density matrix renormalization group studies of low-dimensional magnetic systems and conjugated polymers
To conclude, we have performed symmetrized DMRG calculations on the extended Hubbard–Peierls model. We have presented the dependences of exciton binding energy both on alternation ? and nearest-neighbor interaction parameter ... -
Studies on the ionic conduction in metal oxides and composite electrolytes with a supplementary study of the dielectric properties of some novel oxides of the Aurivillius family
The present investigation suggests that the charge-carrier concentration in the composites exhibiting conductivity enhancements is as high as in a fast-ion conductor. The study also proves that both morphology and particle ... -
Extensions of mode coupling theory to study diffusion and viscosity and applications to chemical dynamics
In this chapter, the existing mode coupling theory [14] has been extended to calculate the diffusion of a tagged molecule and to study the dynamics of a neat liquid. It has been shown that in the earlier theory the definition ... -
Slow dynamics in binary and polydisperse liquids : mode coupling theory and computer simulation studies of diffusion, density relaxation and composition fluctuation
Isothermal–Isobaric (NPT) Ensemble Molecular Dynamics Simulations of Composition Fluctuations and Diffusion in Binary Mixtures In this chapter, isothermal–isobaric (NPT) ensemble molecular dynamics simulations have been ... -
Theoretical study of the linear and nonlinear optical properties of conjugated systems
Hyperpolarizabilities of conjugated ?-electron systems within and correlated Pariser–Parr–Pople (PPP) Hamiltonian have been studied. The polarizabilities of polyenes have been used to estimate the shift in optical gaps in ... -
Investigation of electrical and magnetic transport properties of perovskite related metallic and magnetic oxide thin films and multilayers
a) Thin films of LBCO and LBCNO grown by PLD on LAO (100) and STO (100) substrates showed (001) growth. b) Study of their transport properties showed semiconducting behavior in the a–b plane and metallic along the ... -
Studies in sulphanilamides and sulphones
STUDIES IN SULPHANILAMIDES AND SULPHONES SECTION A: STUDIES ON SULPHANILAMIDES Part I: Introduction This part deals, in brief, with (i) the history and advance of chemotherapy, (ii) discovery and development of the ... -
Synthetic approaches towards 1,24-dihydroxyvitamin D3 and analogues
A formal total synthesis of 1?,24(S)- and 1?,24(R)-dihydroxyvitamin D? (14 and 13) starting from the abundantly available cholic acid (71) is described in this chapter. Cholic acid (71) was first converted into methyl ... -
Study of transient state structures of quinones from Resonance Raman Spectroscopy
The time-resolved resonance Raman spectra of the triplet excited state, radical anion, and semiquinone radical of bromanil have been recorded. Observed vibrational modes have been assigned for all three transient species ... -
investigation of vilsmeier- haack reaction on homoallyic
The thesis entitled "Investigation of Vilsmeier-Haack Reaction on Homoallylic, Allylic and Benzylic Alcohols" consists of seven chapters. Chapter 1 contains an account of the investigation of Vilsmeier reaction on the ... -
Supramolecular chemistry : A bile acid based approach
Chapter 1 Contains three parts: Part A – Describes the design, synthesis, and evaluation of a bile acid-based adenine/biotin receptor. Part B – Discusses the site-specificity of adenine binding observed for aliphatic and ...
