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 ...
Stable Isotopic Composition of Rice Grain Organic Matter as an Archive of Monsoonal Climate
(2018-08-30)
Rice grows in saturated soil water condition and its requirement for water is highest amongst other cereal crops. In India, the southwest monsoon wind regime brings rainfall that provides a favourable environment for rice ...
Thermodynamics of Distributed Solar Thermal Power Systems with Storage
(2018-08-11)
Distributed power generation through renewable sources of energy has the potential of meeting the challenge of providing electricity access to the off-grid population, estimated to be around 1.2 billion residing across the ...
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 ...
Contaminant Transport through Soil and Effect of Bentonite and super-absorbent Polymer on Transport Parameters
(2018-08-20)
The aim of this present research is to improve the containment properties of clayey soil by the use of bentonite and polymers as the additives. Clayey soils are generally used for the control of soil and water pollutions ...
A Study of Two Problems in Nonlinear Dynamics Using the Method of Multiple Scales
(2018-08-13)
This thesis deals with the study of two problems in the area of nonlinear dynamics using the method of multiple scales. Accordingly, it consists of two parts.
In the first part of the thesis, we explore the asymptotic ...
Precipitate Growth and Coarsening in Ternary Alloys
(2018-08-20)
We have studied precipitate growth and coarsening in ternary alloys using two different phase held models.
The first one is a ternary extension of the classical Cahn-Hilliard (C-H) model in which both the phases are ...
Experimental Study of Patterns in Hydrodynamically Deposited Dispersed Phase of CaCO3 on Surfaces of Straight Cylindrica Silica Tubing
(2018-08-13)
Deposition of dispersed phase from flowing dispersions onto a substrate surface is of utmost relevance for various industrial processes like fouling of sparingly soluble salts, such as CaCO3 and CaSO4 in heat exchangers and ...
Structure and Dynamics of the Inter-tropical Convergence zones
(2018-08-13)
The east-west oriented cloud bands in the tropics are called the Inter-tropical Con-vergence Zones (ITCZ). Till recently, the ITCZ has been assumed to have a simple vertical structure with convergence near the surface ...
