Investigations of Sensors Based on New Molecular Architectonics: Synthesis, Fabrication and Application
Rapid industrialization and expansion of urban landscapes in large cities generate maximum polluting ingredients to the surrounding environment. While organic contaminants are naturally occurring, the increase in human ... -
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 ... -
Vorticity and scalar transport in turbulent round jets with and without heating
The round turbulent jets are ubiquitous in both natural and engineered systems such as clouds, engine exhausts, chimney plumes, and respiratory flows. We aimed to understand the vorticity and scalar transport in turbulent ... -
Intense Rainfall Events over the West Coast of India
West coast of the Indian peninsula is one of the regions which receive very heavy rainfall during the summer monsoon season. Average June-September rainfall over the parts of coastal Karnataka, Konkan and Goa exceed 250 ... -
Effect of Electric Current Pulses on Pre-cracked Thin Metallic Conductors: From Crack Propagation to Healing of Cracks
Both scientifically and technologically, it is important to investigate the effects of electric current on the structural integrity of metallic components. As an electric current reverses its direction across a crack, ... -
Rheology of dense non-Brownian suspensions
Suspensions are ubiquitous in nature and industry, ranging from magma, blood, and mud to cement, paint, and molten chocolate. Despite the Newtonian nature of the suspending fluid and the expectation of linearity in the ... -
Experimental and Numerical Evaluation of Mechanical Response of Unsaturated Soils and Their Application to Embankments and Footings
Naturally, soils are rarely fully saturated, and climatic and environmental conditions frequently cause moisture content to change. Due to the varying climate changes and its effects on compacted engineering structures, ... -
Inkjet-printed high performance oxide electronics and its application at sensor interfaces
Over the last two decades, printing of oxide semiconductors has received special attention due to its advantages such as low processing temperature, even at room temperature; high electron mobility; good transparency due ... -
Thermoplastic epoxy designed using Vitrimer chemistries
Globally, 70 million tons of epoxy thermosets are manufactured at a perplexing rate which constitutes approximately a quarter of polymer generation by weight. A thermosetting polymer contains a permanent crosslinked network ... -
Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ... -
Uniaxial Fatigue Behavior of Freestanding Platinum-Aluminide (PtAl) Bond Coat
Pt-aluminide (PtAl) bond coat is used as a part of Thermal Barrier Coating (TBC) system on Ni-base superalloy components in advanced gas turbine aeroengines. The thickness of B2-NiAl intermetallic based diffused coating ... -
Model-based Evaluation of Multiple Solutions to Grid Integration Challenges of Large-scale Renewable Power
Worldwide renewable installations are growing exponentially in the electricity mix. In a renewable-rich electricity grid, the demand, as well as the generation, varies in different time scales. It is highly complicated to ... -
Aggregate and Disaggregate-level Models of Public Transit Ridership in Bengaluru, India
Ridership forecasting models are valuable tools for public transit agencies to assess and quantify the possible impacts of their operational strategies and service improvements on transit demand and revenue. Although ... -
Mesoscale Modelling of sheared lamellar mesophases
The lamellar phase or smectic lyotropic liquid crystalline medium, which is made up of alternating flat sheets of water and surfactant bilayers shearing past each other in an imposed flow. Surprisingly, In practical ... -
Exploring Hydrological Processes, Modeling Decisions, and Deep Learning for Improved Hydrologic Assessment
Hydrological modeling is complicated by the intricate challenges and uncertainties associated with understanding hydrological processes. This thesis aims at answering some of the key research questions related to ... -
Numerical Simulations of Deforming Capsules and Cells in a flow
Understanding the evolution of deforming capsules and cells in various flow configurations can assist in better diagnosis of diseases like Malaria and sickle cell anemia. Flow of deformable capsules is also useful in ... -
Investigation of multiscale biological phenomenon using kinetic modeling and molecular dynamics simulations
Biological systems inherently function at multiple spatial and temporal scales by integrating information across these scales. In this thesis, we are interested in investigating two classes of biological phenomena that ... -
Micromechanical understanding of the macroscopic features of dense granular materials
The prevalence of granular materials in nature (soil, beach sand, rubble pile asteroids) and in several industries (cement, food grains, pharmaceutical powders) has motivated extensive research towards understanding the ... -
Longitudinal Acceleration-based Variable Speed Bio-inspired Guidance Law
Most analyses of existing interceptor guidance laws assume the interceptor speed to be constant, which simplifies mathematical analysis and enhances predictability in interception characteristics. In reality, this is not ... -
Ecology of the terrestrial carbon cycle: Influence of climate and animals
The terrestrial carbon (C) cycle involves fluxes between multiple pools that determine ecosystem functions and regulate global climate. These fluxes and pools are influenced by changes in abiotic (temperature, precipitation ...
