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 ...
Experimental and Theoretical Studies of Liquid Drop Impact on Solid Surfaces Comprising Smooth and Texture Portions
(2018-08-10)
Solid surfaces featuring a spatial variation of surface wettability along particular directions on their surface, referred to as wettability gradient surfaces, are becoming increasingly important in practical applications ...
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 ...
