An investigation into the axial dipole field and mantle-induced heterogeneity in Earth
The Earth’s axial dipole field is generated by dynamo action in the planet’s outer core. It is understood from observations that the convection in the outer core is influenced by the lateral heterogeneity in the overlying ...
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ...
Bioinspiration for battling bacteria: Nature inspired high aspect ratio nanostructures for new age antibacterial surfaces
Bacterial colonization and biofilm formation on abiotic surfaces effectuate corrosion,
fermentation, and infection resulting in tremendous economic and human losses each year.
Aggravating the situation, new multi-drug ...
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 ...
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 ...
Ground Displacements and Stresses around Single and Twin Tunnels using Analytical and Numerical Approaches
Significant emphasis is given nowadays on exploring underground space- in the form of
tunnels- for (i) fast commuting in urban areas, (ii) connectivity to remote areas under different
weather conditions, (iii) military ...
High-Throughput Bending Tests for Investigating Creep Behavior Affected by Structural and Microstructural Inhomogeneities
The bending of cantilevers is an alternate technique for the extraction of power-law creep parameters of materials. It has been shown earlier that in homogeneous systems showing tension-compression symmetry, digital image ...
Damping of magnetic-Coriolis waves with imposed magnetic field orthogonal to the axis of rotation
Small-scale columnar structures (<10 km radius) in Earth's outer core result from inertial waves. In highly conducting fluid, magnetic field behaviour resembles stretched elastic strings and transmits disturbances as Alfvén ...
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 ...
