Phase transformation materials are characterized by their ability to rapidly and reversibly switch between distinct properties, such as insulating and conducting, paramagnetic and ferromagnetic, or Li-rich and Li-poor. These transformations, however, are accompanied by abrupt structural changes in the crystal lattices, which can nucleate defects, accumulate strain energy, and accelerate material decay. We investigate these […]

Specific modal and non-modal mechanisms (flow coherences) in fluid flows, associated with distinct time and length scales, govern important flow phenomena, e.g., laminar-to-turbulent transition, turbulent drag, and flow separation. Consequently, numerous passive strategies featuring compliant materials have explored the effect of Fluid-structure interaction (FSI) on various flow coherences. In recent years, the emergence of Phononic […]

With the climate change becoming as one of the main challenges for human existence, every sector has to contribute in reducing its climate footprint. Being an international and hard to abate sectors, aviation is struggling to find a viable replacement for kerosene. This talk focuses on a novel multi-fuel combustion strategy that is aimed at […]

The intriguing annual migration of the dragonfly species, Pantala flavescens, was reported a century ago. The multi-generational, transoceanic migration circuit spanning 14000-18000 kms, from India to Africa is an  astonishing feat for an insect few cms in size. Wind, precipitation, fuel, breeding, and the life cycle affect  the migration, yet understanding of their collective role […]

Abstract: The presentation opens with a comparison of high-temperature materials with everyday metals. This will be followed by a discussion of challenges and an understanding of the machinability of high-temperature materials. Next, various strategies for machining high-temperature materials, along with practical real-life case studies, will be presented. We will be introducing the concept of Feed […]

Laser beam is highly affected by prevailing atmospheric conditions and limit the system performance for various applications. The talk mainly covers the cause of optical turbulence, its effects on laser beam and further discuss the technologies for controlling the beam for enhancing the effectiveness. Two main techniques namely the Tip-tilt correction for maintaining the beam […]
