TEM Characterization of Microstructural Evolution of GaN Grown by MOCVD on c-Sapphire
III-Nitrides (AlN, GaN, InN) find use in the high-power high frequency applications. Bulk GaN substrates are difficult to grow, therefore the GaN based structures must be grown on foreign substrates. In this thesis, ... -
Tensile And Low Cycle Fatigue Behavior Of A Ni-Base Superalloy
(2009-12-14)Background and Objective: Nickel-base superalloys, strengthened by a high volume fraction of Ni3Al precipitates, have been the undisputed choice for turbine discs in gas turbines as they exhibit the best available combination ... -
Tensile Behavior Of Free-Standing Pt-Aluminide (PtAl) Bond Coats
(2016-05-03)Pt-aluminide (PtAl) coatings form an integral part of thermal barrier coating (TBC) systems that are applied on Ni-based superalloy components operating in the hot sections of gas turbine engines. These coatings serve as ... -
Testing Methodologies for Probing Site Specific Fatigue Response of Graded Coatings
Thermal barrier coating systems (TBC’s) employed in the high pressure turbine section of a modern aero-turbine engine serve as an example of constrained material systems used for engineering applications. TBC’s today are ... -
Theoretical and Numerical Study of Microstructure Formation in Multi-component Alloys
The length scale, composition, orientation of the phases in a material constitutes its microstructure. In order to appreciate the whole gamut of microstructures observed in multi-component alloys, an identification of the ... -
Therapeutic Applications of Biodegradable Chitosan Based Polyelectrolyte Nanocapsules
(2018-01-18)The past few years have witnessed significant work being directed towards drug delivery systems with layer-by layer (LbL) technique prominently featured as one of the most sought after approach. However, majority of the ... -
Thermo-Mechanical Processing of Third Generation γ – Titanium Aluminides
The γ – TiAl based intermetallics are characterized by unique combination of the properties which make these materials amenable for the application in gas turbines. However, due to problems related to limited plasticity ... -

Thiophene Derivative Photovoltaics : Device Fabrication, Optimization and Study of Charge Transport Characteristics
(2018-04-11)In the recent years area organic photovoltaics is generating a lot of interests because whole process of synthesis and fabrication is less energy intensive process as well as it is cost effective compared to conventional ... -
Tufting of carbon fibre/epoxy composites for improved damage tolerance
Laminated composite structures are susceptible to delamination and debonding during their service life due to their poor out-of-plane interlamellar properties. Such damage can occur either during manufacturing or during ... -
Understanding the demixing behavior and structure-property correlation in graphene oxide containing LCST blends
A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ... -
Whisker Growth from Electrodeposited Sn Coatings - Developing Materials Science and Mechanics Based Insights
(2018-05-23)Pure Sn and Sn-alloys are widely used in electrical and microelectronic devices as protective layer to prevent oxidation of Cu conductors and also as a component of Pb-free, Sn-based solders. Sn coatings, typically 0.5-10 ...
