Slow Dynamics In Soft Condensed Matter : From Supercooled Liquids To Thermotropic Liquid Crystals
(Indian Institute of Science, 2007-06-20)
This thesis, which contains fourteen chapters in two parts, presents theoretical and computer simulation studies of dynamics in supercooled liquids and thermotropic liquid crystals. These two apparently diverse physical ...
Molecular Simulations Of Temperature Induced Disorder And Pressure Induced Ordering In Organic Molecular Crystals
(2007-09-05)
Crystallographically solids with well defined crystal structures are normally assumed to be highly ordered. However, it is not uncommon to find considerable degree of disorder amongst many of these crystalline substances. ...
Perovskite Related Oxides: Development Of New Synthetic Methods, Materials And Properties
(2007-10-06)
Oxides of ABO3 composition (A = alkali, alkaline earth or rare earth metal in general, B = transition metal) constitute a large family of metal oxides of current interest to solid state and materials chemistry. Among the ...
Synthesis And Investigation Of Transition Metal Oxides Towards Realization Of Novel Materials Properties
(Indian Institute of Science, 2007-03-23)
Transition metal compounds, especially the oxides, containing dn (0 ≤ n ≤ 10) electronic configuration, constitute the backbone of solid state/materials chemistry aimed at realization of novel materials properties of ...
Ruthenium Complexes Of Chiral And Achiral Phosphorus Ligands Based On The P-N-P Motif
(2007-09-05)
In recent years there is an increasing awareness of the importance of chiral phosphorus ligands in transition metal organometallic chemistry because of the utility of such complexes in homogeneous catalytic reactions. This ...
Influence Of The Bite Angles Of Chelating Diphosphine Ligands In The Chemistry Of Ruthenium Hydride And Dihydrogen Complexes
(Indian Institute of Science, 2007-06-22)
The bite angle of a diphosphine ligand plays an important role in determining the reactivity of a transition metal complex. The coordinated dihydrogen on a transition metal center can be activated toward homolysis or ...
Studies On Electrode Materials For Lithium-Ion Batteries
(2007-11-16)
In the early 1970s, research carried out on rechargeable lithium batteries at the Exxon Laboratories in the US established that lithium ions can be intercalated electrochemically into certain layered transition-metal ...
Investigation Of A Novel Class Of Conducting Polyaniline And Related Systems
(2007-10-25)
The interest in conjugated polymers has been two-fold. A rich variety of intriguing physical phenomena, combined with its immense technological implications in the area of molecular electronics, sensors etc. has inspired ...
Chemical Characterisation Of The Surfaces And Interfaces Of Barium Titanate And Related Electronic Ceramics
(2007-10-25)
This thesis deals with the investigations on the atomic composition, chemical surface states and microstructural features of barium titanate and other electronic ceramics namely barium polytitantes, calcium manganites and ...
Charge-Transfer Associated Photoluminescence Of Rare-Earths Doped Oxide Phosphors
(2007-12-29)
Luminescent materials can be found in a broad range of everyday applications. While in the seventies and eighties, the field of luminescent materials seemed to be fairly well covered, research in nineties has been revitalized ...
