Phase Transformation Behavior Of Embedded Bimetallic Nanoscaled Alloy Particles In Immiscible Matrices
(2017-02-16)The aim of the present thesis is to understand the phase transformation behavior of embedded alloy nanoparticles embedded in immiscible matrices. Embedded alloy inclusions have been dispersed in immiscible matrix via rapid ... -
Phase transition at critically, poisson convergence of isolated vertices and connectivity in random connection models
This work has two parts. The first part contains the study of phase transition and percolation at criticality for three random graph models on the plane, viz., the homogeneous and inhomogeneous enhanced random connection ... -
Phase Transition In Soft-Condensed Matter Fluids And Contribution To Enzyme Kinetics Including Kinetic Proofreading
(2016-11-16)The thesis involves computer simulation and theoretical studies of phase transition in soft-condensed matter systems and theoretical understanding of enzyme kinetics along with kinetic proofreading of tRNA-aminoacylation ... -
Phase Transitions And Magnetic Order In Multiferroic And Ferromagnetic Rare Earth Manganites
(2011-03-29)Recent findings of multiferroicity and magnetoelectric effects in rare earth manganites have fuelled research in this class of materials. These multiferroics can be structurally divided into two classes – orthorhombic and ... -
Phase Transitions And Relaxation Processes In Water And Glycerol-Water Binary Liquid Mixtures : Spin Probe ESR Sudies
(2010-11-18)A liquid Cooled below its normal freezing temperature is known as a supercooled liquid. On further cooling, supercooled liquids crystallize to thermodynamically stable, ordered structures. Alternatively, if the cooling ... -
Phase transitions of fluids confined in nanopores
Confined nanoscale fluids occur in many technologically important phenomenon such as boundary lubrication, adsorption, adhesion and catalysis. Fluids confined at these length scales are spatially inhomogeneous and fluid ... -
Phase-field modeling of equilibrium shapes of precipitate and growth instabilities in the presence of coherency stresses
Precipitation-hardened alloys are one of the most technologically significant materials that are used for structural applications, where an important mode of strengthening is due to the impediment to the movement of ... -
Phases, Transitions, Patterns, And Excitations In Generalized Bose-Hubbard Models
(2016-09-12)This thesis covers most of my work in the field of ultracold atoms loaded in optical lattices. This thesis can be divided into five different parts. In Chapter 1, after a brief introduction to the field of optical lattices ... -
Phasons,topological defects and dynamics in incommensurate matter
In this thesis, we derive some physical consequences of the existence of a phason mode in incommensurate materials. We consider two main examples of such materials-quasicrystals and the incommensurate twist grain boundary ... -
Phenomenological Explorations in Dark Matter
The previous decade has seen an explosive increase in explorations into the nature of dark matter (DM) encompassing astrophysical, particle and cosmological probes. We face today a large body of gravitational evidences ... -
A phenomenological one-dimensional model for elastic ribbons
Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of a unique combination of geometric dimensions. The recent interest in examining engineering applications of ribbon-like structures ... -

The Phenomenon Of Blastocyst Hatching : Role Of COX-2 And NF-kB
(2014-12-01)The zona-pellucida (zona, ZP) is an adhesion-refractory, acellular coat enclosing the rapidly growing, free-living mammalian preimplantation embryo which undergoes successive cleavage divisions to form the blastocyst, ... -
Phonon Anomalies And Phase Transitions In Pyrochlore Titanates, Boron Nitride Nanotubes And Multiferroic BiFeO3 : Temperature- And Pressure-Dependent Raman Studies
(2013-09-13)This thesis presents experimental and related theoretical studies of pyrochlore titanate oxides, boron nitride nanotubes, and multiferroic bismuth ferrite. We have investigated these systems at high pressures and at low ... -
Phonon anomalies in pyrochlores and 2D materials under extreme conditions: Insights from Raman spectroscopic studies
In solids, electrons do not behave as separate particles but instead interact intensely to form quasiparticles, which couple with other quasiparticles such as phonon, plasmon, and exciton to generate emergent quantum ... -
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ...
