Transition metal phosphide nanostructures encapsulated in N,P co doped nanotubes for water splitting in wide pH range
In order to make clean and sustainable energy conversion, systems primarily requires the development of highly efficient and robust catalysts. One of the main challenges for designing the catalysts is to minimize the cost ... -
Experimental Studies on Methanol Sprays for IC Engine Applications
In this work, studies have been conducted on sprays of methanol and its emulsions with diesel towards assessing the potential of methanol as an alternative fuel for IC engines. Methanol can be used in compression ignition ... -
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste (LILW) and high-level waste (HLW), based on their level of radioactivity and the time taken for decay. The low and intermediate level ... -
Lessons for Gravity from Entanglement
One of the recent fundamental developments in theoretical high energy physics is the AdS/CFT correspondence [1, 2, 3, 4] which posits a relationship between Quantum Field Theories (QFT) in a given dimension and String ... -
Two-Dimensional Nanomaterials for Chemiresistive Gas Sensors: Towards Development of Breath based Diagnostics
Breath based Diagnostics (BbD) can enable a paradigm shift in the Point-of-Care Diagnostic (PoCD) devices. Exhaled human breath has been demonstrated to contain over 2000 volatile organic and inorganic compounds, some of ... -
Flutter Identification and Aeroelastic Stability during Wake Penetration
Demonstration of utter stability over the design envelope and identi fication of safe ight envelope is a prerequisite for operational clearance of any new aircraft design. An important step involved in flight flutter ... -
Role of Power Control in Enhancing the Performance of Opportunistic Selection Schemes
Opportunistic selection reaps the benefits of multiuser diversity in many wireless applications. For example, it increases throughput of cellular networks, lifetime of wireless sensor networks, and improves diversity in ... -
Applications of Magnetic Helical Nanomotors: From Cancer Biology to Dentistry
Micron/nano sized machines promise precise targeting and drug-delivery at hard to reach places inside the human body. There have been tremendous efforts in this direction and various remotely powered artificial nanomachines ... -
Patterns and Drivers of Multimodal Signalling in Diurnal Geckos
Effective communication in animals comprise emission of a signal by a signaller and a response by a receiver, such that the interaction is beneficial to either only the signaller, or both the signaller and the receiver. ... -
Nonequilibrium dynamics and thermodynamics of some single-particle activity-induced diffusive systems
In the mesoscopic world, diffusion is a ubiquitous process and it is usually explained by the Einstein’s theory of Brownian motion (BM). However, in the biological systems, some peculiar dynamical behaviors are observed ... -
Tufting of carbon fibre/epoxy composites for improved damage tolerance
Laminated composite structures are susceptible to delamination and debonding during their service life due to their poor out-of-plane interlamellar properties. Such damage can occur either during manufacturing or during ... -
A simple method for measurement of high power, inline beam quality of high-power lasers
Over the past few decades, applications of high-power fiber laser in the area of material processing, medicine, defence, high precision micro-machining etc., is rapidly increasing. The primary reason behind thriving ... -
Investigations on Impinging Shock Wave and Boundary Layer Interactions in Hypersonic Flow
Shock boundary layer interactions (SBLIs) rank among the most fundamental problems in high-speed aerodynamics and are a primary concern in hypersonic flows. Shocks at hypersonic speeds are typically strong enough to separate ... -
Experimental and Numerical Studies on Low Emission Syngas Combustion
The present study concerns experimental and numerical investigation of the combustion of low-calorific value syngas in an optically accessible reverse flow combustion chamber. Several modes of operation are investigated ... -
Identifying key determinants underlying variable efficacy of BCG substrains against Pulmonary TB.
Protection conferred by BCG vaccine against adult pulmonary TB ranges from 0–80% based on large, well-controlled field trials. This variability is highly significant (P < 0.0001) and is regarded as being indicative of true ... -
Crystallographic and analytical ultracentrifugation studies of the E. coli acetohydroxy acid synthase I enzyme
This thesis ellucidates the mechanism of activation and regulation of AHAS I enzyme from Escherichia coli that was characterised using crystallographic and sedimentation velocity analytical ultracentrifugation studies. AHAS ... -
Design, Fabrication and Characterization of Metal Oxide Semiconductor Based MEMS Gas Sensors for Carbon Monoxide Detection
In recent years, intense efforts have been made towards the development of miniaturized gas-sensing devices for hazardous gas detection. Carbon monoxide, which is a result of incomplete combustion, is a colourless, odourless, ... -
A phenomenological one-dimensional model for elastic ribbons
Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of a unique combination of geometric dimensions. The recent interest in examining engineering applications of ribbon-like structures ... -
Characterization of mouse Apolipoprotein L9 and investigation of its cellular functions
This thesis is divided into 3 chapters. Chapter 1, titled General Introduction, is a chapter that familiarizes the reader with the general subject matter of the thesis so that the content of Chapters 2 and 3 can ... -
Small Heat Shock Proteins from Bacteria and a Bacteriophage
Proteins can unfold during heat and other types of stress and tend to aggregate with subsequent loss of function. This event is prevented by small Heat Shock Proteins (sHSPs) acting as molecular chaperones. sHSPs do not ...
