Novel Spectral Processing Methods in NMR – Wavelet Transform and Pattern Based Analysis
NMR spectroscopy provides a variety of information leading to an understanding of the properties of different materials. To extract this information from the experiments, one needs to have noise and artifacts free spectra ... -
Novel spin, charge, and lattice dynamics in pyrochlore iridates : Raman and X-ray diffraction studies at low temperatures and high pressure
This thesis investigates phonon dynamics, electronic, and spin excitations along with structural instabilities and phase transitions in rare earth pyrochlore iridates, A2Ir2O7 (A = Pr, Gd, Dy, and Er) and Bi-doped Sm2Ir2O7 ... -
Novel Upwind and Central Schemes for Various Hyperbolic Systems
(2018-05-21)The class of hyperbolic conservation laws model the phenomena of non-linear wave propagation, including the presence and propagation of discontinuities and expansion waves. Such nonlinear systems can generate discontinuities ... -
De Novo Design Of Protein Secondary And Super Secondary Structural Elements: Investigation Of Interaction Patterns From The Crystal Structure Analysis Of Oligopeptides Containing α,β-Dehydrophenylalanine Crystal Structure Analysis Of Double Mutant M37L, P40S Thioredoxin From E.Coli
(2007-12-06)ΔPhe an analogue of a coded amino acid phenylalanine (Phe) residue but with double bond between Cα and Cβ atoms, is one of the well studied residue among all the dehydro amino acids, as a conformation constraining amino ... -
Nuclear magnetic resonance inestigations at high....pressure
In this review it has been attempted to give a summary of the MR experiments which have been used to investigate high pressure effects on the molecular motion, diffusion and phase transitions in solids. These experiments ... -
Nuclear magnetic resonance investigations of certain protonic conductors.
Ionic motion in the hydrate of ammonium ferrocyanide has been investigated by high?pressure wide?line NMR, high?resolution NMR and conductivity techniques. In the high?pressure NMR study, the room?temperature proton NMR ... -
Nuclear quadrupole resonance and relaxation - instrumentation and investigations in group V Trihalides
In the present investigation, we have used nuclear quadrupole resonance (NQR) as a local probe to study the structural and dynamical aspects of Group V trihalides. For this purpose, we have set up a pulsed NQR spectrometer ... -
