Establishment of an Experimental System in India to Measure the Mixing Ratio and Stable Isotopic Composition of Air CO2 & Observations from Urban and Marine Environments
(2018-04-11)
The thesis presents observations on the CO2 mixing ratio and the carbon isotopic ratio (13C/12C i.e. δ13) of atmospheric CO2 from the Indian region, for the period 2008 - 2011. An experimental system was established at the ...
Evaluating Geochemical Proxies for Paleoclimate Reconstruction in Tropical Montane Peat : A Case Study from the Nilgiris, Southern India
(2018-05-14)
Peat from the temperate regions has been used for paleoenvironmental reconstruction using diverse proxies for over a century now. Peat is rare and severely understudied in the tropics. The montane peat bogs of the Nilgiris, ...
Mechanical Characterization of Carbon Nanotubes and Nanocomposites
(2018-08-14)
Measurement of all the mechanical properties of carbon nanotubes is extremely difficult because of its small size. In the present work, all the five transverse isotropic properties of single wall carbon nanotubes (SWCNTs) ...
Advanced Optimal Control Design for Nonlinear Systems including Impulsive Inputs with Applications to Automatic Cancer Treatment
(2018-08-14)
The motivation of this research is to propose innovative nonlinear and optimal control design algorithms, which can be used in real life. The algorithms need to be computationally efficient, should deal with control ...

(2018-08-14)
Ferroelectric ceramics are very promising materials for a variety of piezoelectric applications such as high permittivity dielectrics, piezoelectric sensors, piezoelectric/electrostrictive transducers, actuators, electro-optic ...
Diffusion Controlled Growth of A15-Based Nb3Sn and V3Ga Intermetallic Compounds
(2018-08-09)
The A15-based Nb3Sn and V3Ga superconducting compounds are an integral part of synchrotrons and magnetic fusion reactor technology, especially where a magnetic field higher than 10 T is required, which lies beyond the limit ...
On the Factors Influencing the Stability of Phases in the Multiferroic System BiFeO3-PbTiO3
(2018-08-11)
Rhombohedral perovskite BiFeO3 is a single phase multiferroic compound exhibiting both magnetic (Neel temperature ~370˚C) and ferroelectric (Curie point ~840˚C) ordering well above the room temperature. Ferroelectricity ...
Diffusion-Controlled Growth of Phases in Metal-Tin Systems Related to Microelectronics Packaging
(2018-08-28)
The electro–mechanical connection between under bump metallization (UBM) and solder in flip–chip bonding is achieved by the formation of brittle intermetallic compounds (IMCs) during the soldering process. These IMCs ...
In-Situ Polymer Derived Nano Particle Metal Matrix Composites Developed by Friction Stir Processing
(2018-08-10)
Ceramic metal matrix composites (CMMCs) are materials generally created by mixing of hard ceramic particles in a metal matrix. They were expected to combine the ductility and toughness of the metal with the high strength ...
Experimental and Numerical Investigation of an Evaporating Meniscus in a Capillary Slot : Microscale and Pore Scale Studies
(2018-08-09)
An evaporating meniscus formed by a wetting °uid in a heated capillary slot with capillary driven °flow is numerically and experimentally investigated at the microscale and pore scale.
In the microscale analysis, the ...
