Processing And Characterization Of B4C Particle Reinforced Al-5%Mg Alloy Matrix Composites
(Indian Institute of Science, 2005-12-22)Metal matrix composites (MMCs) are emerging as advanced engineering materials for application in aerospace, defence, automotive and consumer industries (sports goods etc.). In MMCs, a metallic base material is reinforced ... -
Processing And High Temperature Deformation Of Pure And Magnesia Doped Alumina
(Indian Institute of Science, 2005-12-22)Creep resistance is an important design criterion at high temperatures especially when continuous attempts are made to increase the efficiencies by increasing the operating temperatures. Alumina is an important high ... -
Processing mediated polymorphism in PVDF-based dielectric polymers and their application
The ever-increasing demand in electronic devices, piezoelectric materials such as ceramics, polymers and polymer ceramic composites with enhanced piezoelectric and dielectric properties has become the focus of many ... -
Processing Of Zirconia Based Honeycombs And Evaluation Of Thermo Mechanical Properties
(2010-08-16)Ceramic cellular solids, mainly honeycombs and foams, are a novel class of composite materials where one phase is an interconnected network of solid struts or plates and the other one an empty phase or possibly a fluid. ... -
Processing, Characterization And Evaluation Of A Functionally Graded Ai - 4.6% Cu Alloy
(Indian Institute of Science, 2005-12-22)In some applications the stress across the entire cross-section of a component is not uniform but varies with position. For example, maximum shear stress is highest at the inner surface of a thick-walled cylinder subjected ... -

Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
Prospects of Bioethanol from Estuarine Macroalgae
Burgeoning dependence on fossil fuels for transport and industrial sectors has been posing challenges such as depletion of fossil fuel reserves, enhanced greenhouse gas (GHG) footprint, and imminent changes in the climate, ... -
Pseudo-binary and Pseudo-ternary diffusion couple methods for understanding the growth of interdiffusion zone between bond coat and superalloys
Ni-based superalloys are widely used in jet engine applications. Bond coats are applied to these alloys for protection during service in a very harsh environment at high operating temperature. The addition of Pt to the ... -
Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures
(Indian Institute of Science, 2005-07-27)This thesis is devoted to the deposition of intermetallic thin films by laser ablation deposition (LAD) and their characterization. Pulsed laser ablation and subsequent deposition of the ablated vapours produces films under ... -
Quality-quantity trade off during antibody production and the design of optimal passive immunization protocols
Passive immunization has been used classically to rapidly clear antigen and reduce disease burden. Surprisingly, recent studies have found passive immunization to induce lasting improvements in the humoral response, ... -
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ... -
Quantitative Laser-Based Diagnostics and Modelling of Syngas-Air Counterflow Diffusion Flames
(2018-06-05)Syngas, a gaseous mixture of H2, CO and diluents such as N2, CO2, is a clean fuel generated via gasification of coal or biomass. Syngas produced via gasification typically has low calorific values due to very high dilution ... -
