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 ... -

Phoretic Motion of Colloids : Single Particle and Collective Behaviour
(2017-12-16)In this thesis we have studied systems that driven by mechanisms broadly known as phoresis. More specifically, in the second chapter we calculate the excess noise in electrophoresis of a colloid due to microion fluctuations. ... -
Phosphorus(III) Ligands Based On The P-N-P Skeleton And Their Transition Metal Complexes
(2009-06-05)There is considerable current interest in the design and synthesis of new phosphorus ligands and their transition metal complexes in view of their potential applications in homogeneous catalysis. The present study is ... -
Photo And Thermal Induced Studies On Sb/As2S3 Multilayered And (As2S3)1-xSbx Thin Films
(2013-05-31)Chalcogenide glasses have attracted considerable attention due to their infrared transparency, low phonon energy, and high non linear optical properties. They have been explored as promising candidate for optical memories, ... -
Photo magnetic Investigation and Magneto-structural Correlation of Switchable Molecular Magnetic Materials
Modern life without magnetic materials is almost impossible to imagine. Mobile phones, telecommunication, navigation, computer, television, credit cards, medical equipment, data storage devices, and sensors are an integral ... -
Photo-responsive Self-assembled Coordination Architectures and Their Applications
Development of nanomaterials that mimic enzyme-like catalytic activities (nanozymes) has drawn special attention in recent time. Nanozymes possess exclusive advantages over natural enzymes like high stability, large-scale ... -
Photocatalytic and Photoelectrocatalytic systems for water remediation and energy applications
This PhD work consists of two main parts. The first part focuses on photocatalytic systems for water remediation from bacteria and phenolic compounds, and the second part deals with photoelectrocatalytic systems for biomass ... -
Photocytotoxicity And DNA Cleavage Activity Of Metal Scorpionates And Terpyridine Complexes
(2011-08-22)Scorpionate and terpyridine ligands are of importance in inorganic chemistry for their metal-binding properties. Tris-pyrazolylborate (Scorpionate) ligands that show facial binding mode and steric protection have been ... -
Photoemission Studies Of Metal-Insulator Transition In Some Oxide Bronzes
(2013-06-21)Metal-insulator transition is one of the most important properties observed in certain materials which has been studied widely using a wide range of experimental techniques as well as theoretical models. This kind of a ... -
Photonic Crystal Ring Resonators for Optical Networking and Sensing Applications
(2017-12-03)Photonic bandgap structures have provided promising platform for miniaturization of modern integrated optical devices. In this thesis, a photonic crystal based ring resonator (PCRR) is proposed and optimized to exhibit ... -
Photophysical Properties of Manganese Doped Semiconductor Nanocrystals
(2018-06-08)Electronic and optical properties of semiconducting nanocrystals, that can be engineered and manipulated by various ways like varying size, shape, composition, structure, has been a subject of intense research for more ... -
A Phylogenetic Perspective on The Phytogeography of Western Ghats
I used a finer scale data of 156 published plots across the entire latitudinal range of WG, covering most of the protected forests. The pruned phylogeny for this study consisted of 367 species, of which ~ 50% are taxa endemic ... -
Phylogeny And Biogeography Of Hemidactylus Oken, 1817 Geckos Of The Indian Subcontinent
(2013-02-25)Geckos of the genus Hemidactylus Oken, 1817 are one of the most widely distributed and species-rich groups of gekkonids. With approximately 90 species, the genus Hemidactylus accounts for 10% of the total number of species ... -
Physical controls of chlorophyll distribution in the North Indian Ocean
The north Indian Ocean is one of the highly productive regions among the tropical oceans. Being a prominent monsoon regime, the basin exists as a highly dynamic region charac- terised by intense mixing and upwelling and ... -
