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 ... -
Quantum-Continuum Modeling and Simulations of Semiconductor Nanostructures
This thesis proposes a multi-physics model to couple the electrical, mechanical, thermal and quantum mechanical interactions in semiconductor and their heterostructures. Governing differential equations and constitutive ... -
Quasi-Static and Implicit-Dynamic Finite Element Solution of Large Deformation Elastic Adhesive Contacts Using a Volumetric Interaction Scheme
Adhesive forces, mediated by van der Waals’ and other interactions, dominate the contact response in the micron and sub-micron regimes. Understanding adhesion is especially important in biological systems (interaction of ... -
