Design of Electroactive Materials and Mechanistic Investigations of Metal (Li, Na, Mg)-Sulfur Batteries
The thesis entitled “Design of Electroactive Materials and Mechanistic Investigations of Metal (Li, Na, Mg)-Sulfur Batteries’’ deliberates on some of the important issues impeding the progress of metal sulfur battery (Li/S, ...
Role of spin density and interchromophoric coupling in singlet fission
Singlet exciton fission (SEF) is the transformation of a photoexcited singlet exciton into two triplets localized on two chromophores coupled together. This process therefore produces two triplet excitons at the expense ...
Quantum Phases and Magnetization Plateaus of Skewed Spin Ladders
This thesis deals with theoretical studies of skewed spin ladders which are two legged ladder with periodic slanted rung bonds and can be viewed as periodic fused rings with two different number of vertices. The spin at ...
Supramolecular Self-assembly of Diketopyrrolopyrrole with Emergent Photophysics and Unprecedented Photoconductivity
Structural fluctuation in organic molecular semiconductors often plays a key role in fragmenting the conducting pathways even in their condensed phases due to the large fraction of free volumes, acting as trap sites for ...
Minerals to Functional Materials: Comprehensive Evaluation of Vanthoffites and Related Materials towards Futuristic Multifunctional Applications
The thesis provides a systematic investigation of materials derived from different mineral species such as vanthoffite and related minerals structures. Search of new multifunctional materials continues to be a challenge ...
Ion insertion and Ion-host Interactions in Diketopyrrolopyrrole-based π-Conjugated Polymers
π-conjugated organic semiconductors are a class of technologically important materials with broad applicability in areas as diverse as energy conversion and storage, bioelectronics, and consumer electronics. This is because ...
A Study of Synthesis and Optoelectronics of Copper Iron Chalcogenide Nanocrystals
Copper iron chalcogenides constitute a promising class of optoelectronic materials courtesy of their narrow bandgaps and earth abundant constitution. However, they are yet to receive the attention they deserve due to the ...
Phase Modulated Selective NMR Methods for resolving overlapping spin systems and rapid data acquisition : Application in metabolomics
