Electrochemical Investigations Related to the Next Generation Sodium and Potassium Batteries
The commercialization of Li-ion battery (LIB) in 1990s by Sony Corporation has led to its applications in portable electronic devices such as mobile phones, cameras, laptop computers, etc. Initially, the energy density of ...
Investigations of Chalcogen-Cathodes and a Carbonitride-Anode for Alkali-Based Rechargeable Batteries
In this thesis, we have attempted to understand the working principle of Li(Na)-S(Se) battery
and following such understandings we have attempted towards the design of various S(Se)-
cathode materials for the alkali based ...
InGaN Based 2D, 1D and 0D Heterostructures on Si(111) by Plasma Assisted Molecular Beam Epitaxy
The present research work focuses on the growth and characterization of group III-Nitride (InGaN) epitaxial layers as well as nanostructures on Si(111) substrates. The growth system used in this study was a plasma-assisted ...
A New Class of Boron-Nitrogen Compounds : A Rational Approach for the Design and Development of Smart Materials
Replacing nonpolar homodiatomic C=C unit in a fully carbon -conjugated system with an isoelectronic polar heterodiatomic B-N fragment is an active area of research. The first BN/CC isosterism was demonstrated seven decades ...
Exploring New Designs of Amphiphilic Graft Copolymers and Forays into 2D Polymers
Amphiphilic polymers, wherein two or more immiscible polymeric segments are connected covalently, form an interesting class of macromolecules that can self-assemble in block selective solvents as well as in bulk, to exhibit ...
Controlled Nanoscale Growth of 2D Materials and Their Heterostructures
Unique ranges of properties of two dimensional (2D) materials foster new opportunities in many scientific and technological fields. Beyond pristine 2D materials, their heterostructures provide more possibilities in real ...
Electrical and Non-linear Optical Properties of LiTa(Nb)O3 Nanostructures Evolved in Borate Glass Matrices
The design, fabrication and application of materials that are of dimension(s) in the nanoscale form the basis of nanotechnology. Nanotechnology thrives owing to the anomalous, unique or even at times, extraordinary physical ...
Theoretical Investigation of H-Bonded O-H Vibrations, H-Atom Transfer and C-H Vibrations via Empirical Valence Bond and Local Mode Based Models
In this thesis, I have presented my work on properties of hydrogen(H) bonded systems, H-atom transfer reaction in solution and molecular vibrational spectra through theoretical inves-tigations. The studies are based on two ...
Understanding Ultrafast Molecular Structural Dynamics in Liquids : Ultrafast Raman Loss and Transient Absorption Study
The present thesis deals with the detailed ultrafast experimental studies on the ex-cited state vibrational dynamics of model chemical systems in condensed phase. The molecular systems are studied by means of Ultrafast ...
