Externally Induced Instabilities in Contactless Functional Droplets
Many natural and technological processes involve spray or cluster of droplets which are subjected to chaotic external environment. Study of the behavior of a single droplet is therefore crucial to understand the dynamics ... -
Dynamic Strain Aging and Creep in near-α Ti Alloy, IMI834
IMI 834 is a near- Ti alloy used in high temperature applications such as compressor discs and blades of aero engines. Titanium alloys including IMI 834 are known to exhibit dynamic strain aging (DSA) over the temperature ... -
Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional ... -
Integration of Graphene with Plasmonic Nanostructures for Photodetection in the UV, Visible and IR
Graphene is the thinnest material known till date, composed of a two dimensional (2D) arrangement of carbon atoms in a hexagonal lattice. It has interesting mechanical, electrical and optical properties, such as very high ... -
Molecular Simulation Studies of Competing Pathways in Crystal Nucleation
Microscopic nature of nuclei and extremely fast nucleation events makes it difficult to study nucleation experimentally. Route to nucleation can be effected by different parameters such as thermodynamic conditions, uid ... -
Continuous-Curvature Path Planning Using Four Parameter Logistic Curves
Autonomous vehicles perform time and cost effective operations with minimal or no human effort and hence, have the potential to be used in civilian, commercial and military applications. Pertaining to these applications, ... -
