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 ...

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 ...

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 ...

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 ...

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 ...

This thesis explores the structural and dynamical aspects of small, charged and neutral, solute molecules in both pure water and in aqueous binary mixtures, with emphasis on water-ethanol binary mixture. We employ both ...

Hybrid Organic-Inorganic Lead Halide Perovskites (HOIP) are represented by APbX3, where A is the methylammonium cation (MA: (CH3NH3)+) or the formamidinium cation (FA: (CH(NH2)2)+), X is halide anion. HOIP have emerged as ...

Proteins are biological macromolecules formed by sequentially joining natural amino acids through peptide bonds. The sequence of amino acids in a protein chain determines its three dimensional structure under physiological ...

Gamma radiation being the most energetic form of electromagnetic radiation has applications in number of different fields such as in medicine for treating cancer, food sterilization and in astronomy for studying phenomenon ...

Nuclear Magnetic Resonance (NMR) spectroscopy has had an enormous effect in numerous areas of chemistry, biology, and medicine. Nuclear Magnetic Resonance (NMR) Spectroscopy is a unique analytical technique that permits ...
