Computational study of membrane driven secondary structural changes in proteins
Conformational changes in proteins, the most abundant biomolecule found in all living organisms, are ubiquitous and triggered by several factors essential for protein function. Protein conformational changes typically occur ... -
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ... -
Computational analysis of polymer nanocomposites across length scales
Polymer nanocomposites (PNC) exhibit excellent mechanical properties making them a promising material for several engineering applications. The enhancement in properties is primarily attributed to the toughening and ... -
Accurate Prediction of Enhancement Factors for Water Flow Through Boron Nitride Nanotubes
Water in nanoconfined spaces, such as nanotubes, exhibit anomalous yet intriguing behaviour compared to bulk water, a better understanding of which can enable us to realize a sustainable future. Nanotubes are atomically ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Comprehensive Investigation of the Mechanical Behavior of Nial-x (X=pt, Pd) Alloys: Effect of Composition, Orientation and Temperature
Gas turbine engines in the turbine section operate at temperatures exceeding 1300°C, which can cause high-temperature oxidation and reduce the lifespan of turbine blades. To counter this, thermal barrier coating (TBC) ... -
Towards metal additive manufacturing using alternate powders
Metal powders are predominantly produced using processes derived from atomization, which, apart from being highly energy intensive, are also inflexible and very material specific. These limitations are particularly acute ... -
Climate-resilience of Dwellings in Transition and the Thermal Behaviour of their Inhabitants
Thermal comfort is critical for the well-being, and productivity of the inhabitants. Traditional dwellings constructed using local, low-carbon materials have for decades provided comfortable indoor thermal environment to ... -
Synergistic Effect of Electromagnetic Forces on the Failure of Pre-Cracked Thin Metallic Conductors
Finite element method (FEM) simulations were performed, and distributions of current density, electromagnetic force, and stress fields due to the self induced electromagnetic forces were evaluated in a pre-cracked thin ... -
Precambrian ocean, life, and syn to post-collisional records in the Himalayas (Kumaun)
The Ph.D. thesis focuses on the central sector of the Himalayas, i.e., Kumaun. Here, an attempt has been made to understand the poorly understood genesis of magnesium carbonates (sparry magnesite) of the Precambrian ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Stress-Assisted Pitting Corrosion Studies in Metallic Structures Using Advanced Modeling Methodologies
Pitting corrosion poses a significant threat to deepwater oil and gas production facilities, yet our current understanding of its impact on specific systems such as steel catenary riser (SCR), tensioned leg platforms (TLP), ... -
Investigating Instability Mitigation through Flame Oscillator Synchronization
Stringent emission regulations for reducing NOx and soot emissions are driving gas turbine combustors manufacturers to adopt lean premixed combustion technology. However, the rich dynamics of turbulent, lean premixed ... -
Inverse Material Design using Deep Convolutional Neural Networks and Ontology
Materials design is the process of tailoring materials with specific properties and performance characteristics to meet the particular needs of an application. It involves going back on the process-structure-property (PSP) ... -
Studying the effect of Re on the Co-Ni-Al-Ti-Nb-Cr superalloy’s coarsening kinetics and establishing the high-throughput diffusion couple approach for alloy design
The studies are conducted to understand the effect of Re addition on microstructural evolution and coarsening kinetics of new Co-Ni-Al-Ti-Nb-Cr based superalloys. Lattice misfit is reduced by adding Re, confirmed from ... -
Microstructure – texture - mechanical property correlation in additively manufactured stainless Steel 316L and Cu-Ni-Sn
Metal additive manufacturing (AM) has gained considerable interest in recent years because of its ability of near net shape building of the components, one-go production, ability to make intricate designs and minimized ... -
The role of polymer phase on rigidity percolation of ABS−spherical nickel microparticles composites
Percolation and rigidity transitions are very important phenomena in random heterogeneous microstructures, as various physical properties change abruptly at some critical volume fractions of one phase. The concepts of ... -
Potential Applications of Snail Mucus in Cartilage Repair and Fabrication of Porous 3D Scaffolds
Articular cartilage damage is a major challenge in orthopedics. This medical condition is exacerbated by the cartilage's inability to self-repair due to the non-vascularization of the tissue and many other factors. Several ... -
Secondary Atomization of a Droplet in Diverse Interaction Settings
Secondary atomisation refers to the process by which liquid droplets, which are already in a dispersed state, are further atomised down into smaller droplets. This process occurs after primary atomisation, which is the ... -
