Synthesis and Characterization of Functionalized Electroactive Polymers for Metal Ion Sensing
(2018-02-06)Metal ion contamination in surface and ground water is a major threat as it has a direct implication on the health of terrestrial and aquatic flora and fauna. Lead (Pb2+), mercury (Hg2+), cadmium (Cd2+), nickel (Ni2+), ... -
Synthesis and Characterization of Geopolymers as Construction Materials
(2018-01-09)Geopolymers are a relatively new class of materials that have many broad applications, including use as substitute for ordinary Portland cement (OPC), use in soil stabilisation, fire resistant panels, refractory cements, ... -
Synthesis and Characterization of Intermetallic Coatings by Laser Cladding and Novel Ball Milling Approach
The aim of the present work is to engineer a new kind of coating material with superior quality and reliability in a cost effective way by laser cladding and ball milling process. Non equilibrium processing methods were ... -
Synthesis and Phase Transformation Studies of Al45Mn55 Ferromagnetic Heusler Alloy
The aim of the present thesis work was to synthesize and explore the phase transformation behavior of a binary Heusler alloy based on AlMn system. The intermetallic phase with the stoichiometry AlMn, which is usually termed ... -
Synthesis And Study Of Microstructure Evolution In Nanoparticles Of Immiscible Alloys By Laser Ablation Under Liquid Medium
(2017-05-21)The present thesis deals with synthesis of free alloy nanoparticles in immiscible alloy systems by the process of laser ablation under a liquid. In this process the alloy target is submerged in a liquid and the plume formed ... -
Synthesis and testing of eco-friendly, non-toxic cutting fluid emulsions
The evolutions in the development of metal working fluid (MWF) from petroleum based products have brought remarkable changes to the present growing machining industry. The established MWF/Cutting fluids have reduced the ... -
Synthesis and Transformation of AuCu Intermetallic Nanoparticles
(2018-04-16)Investigations on size dependent phase stability and transformations in isolated nanoparticles have gained momentum in recent times. Size dependent phase stability generates size specific particle microstructure which ... -
Synthesis Of Biodiesel In Supercritical Fluids
(2008-01-25)Alternative fuels are becoming important due to diminishing fossil fuel reserves and the environmental hazards associated with exhaust gases. Biodiesel is an attractive alternative fuel because it is environmentally ... -
Synthesis of Conceptual Designs for Sensors
(2017-11-24)A computer-aided technique is developed in this thesis to systematically generate concepts for sensors of a wide variety. A database of building blocks, based on physical laws and effects that capture the transduction rules ... -
Synthesis of Monodispersed Pdms Microspheres of Tunable Modulus Using Droplet Microfluidics and Study of the Rheology of Dense Suspensions of Rigid and Soft Particles in Shear Flow
We report the synthesis of monodispersed PDMS microspheres of tuneable modulus using a droplet-based microfluidics approach. Nevertheless, polymer microspheres can be used as a model representative particle to mimic the ... -
Synthesis of Thermally Stable Catalysts for Methane Reforming and CO Abatement
The global energy consumption is estimated to reach around 262×1012 kWh/year by 2050 for 9 billion people. It is a challenge to meet global energy requirement via clean fuel (hydrogen) and by reducing/utilizing the CO2 ... -
Synthesis, Microstructural Stability and High Temperature Deformation of Alumina-Carbon Nanotube Composites
Structural ceramics such as alumina are known to have excellent hardness and high temperature mechanical properties. In view of this, they are used as refractory linings to mitigate the effect of high temperature exposure. ... -
System Identification And Control Of Helicopter Using Neural Networks
(2013-04-29)The present work focuses on the two areas of investigation: system identification of helicopter and design of controller for the helicopter. Helicopter system identification, the first subject of investigation in this ... -
Systematic Synthesis And Analysis Of Multi-DOF Toggle Mechanisms For Electrical Switches
(2015-12-07)Electrical switches are ubiquitous. Performance requirement for a switch is stringent. The operating mechanism mostly decides the performance of an electromechanical switch. However, design of such mechanisms, which involve ... -
A Tale of Two Gradients : Atmospheric Dynamics in an Inhomogeneous Background
(2017-11-29)The effects of a non-zero background state on atmospheric dynamics is explored through simple models and observations. Firstly, we examine the effects of moisture gradients on the stability and propagation of Rossby waves ... -
Techno-Economic Evaluation of Rooftop Photovoltaic Systems in the Indian Context
Problems of greenhouse effect and depletion of conventional resources in the last two decades have resulted in a worldwide exponentially growing photovoltaic market for renewable power generation. The Indian government has ... -
