Synthesis and Applications of Unusual Self-assembled Coordination Architectures
Biological systems like enzymes have complex structures which help in executing intricate chemical reactions. Endeavoring to replicate such chemical reactions, chemists have crafted discreate molecular structures ... -
Fabricating Physical and Robotic Systems to Investigate Collective Behavior
The motion of particles has always been fascinating for scientists. We, as scientists, try to decode the mysteries of motion of massive objects like black holes, stars, and planets to objects nearly void of mass such as ... -
Gallium Oxide Vertical Power Devices - Modeling, Material Growth, and Hetero-epitaxial Integration with Silicon
𝛽-Ga2O3 is a candidate for a new generation of power semiconductors that can significantly lower the conduction losses and increase power density in the power converters. PFOM or power figure of merit (V2Br/Ron) is a ratio ... -
Development of an Intraoperative Probe for Brain Tumour Delineation Combining Multimodal Tissue Characterization and Soft-Robotics
Accurate identification of surgical margins in brain tumors is of significant prognostic importance. Despite the availability of 5-ALA and image guidance methods, recognizing tumor boundaries is highly subjective, dependent ... -
Synergistic Exploration of Oxide Cathode Materials for Potassium-ion Batteries
Since their inception by Sony® in 1991, Li-ion batteries have become dominant in various energy storage applications. However, the ever-growing energy demand coupled with sparsely distributed lithium resources provide ... -
Data-Driven Approach to Estimate WCET for Real-Time Systems
Estimating Worst-Case Execution Time (WCET) is paramount for developing Real-Time and Em- bedded systems. The operating system’s scheduler uses the estimated WCET to schedule each task of these systems before the assigned ... -
Phosphate-based Mixed Polyanionic Positive Insertion Materials for Energy Storage Applications
Mixed polyanionic insertion materials offer a rich treasure house to develop robust cathode insertion materials having a desirable combination of chemical and thermal stability, as well as tuneable redox voltage and ... -
Experimental, Numerical and Probabilistic Analysis of Reinforced Anchors for Transmission Tower Foundations
The foundations of tall structures such as transmission towers are subjected to loads in three directions coming from wind and other environmental events. The use of anchors for application in transmission tower foundations ... -
Barrier Function Inspired Reward Shaping in Reinforcement Learning
Reinforcement Learning (RL) has progressed from simple control tasks to complex real-world challenges with large state spaces. During initial iterations of training in most Reinforcement Learning (RL) algorithms, agents ... -
Interaction of hnRNPK with RNA and characterization of its phase separation behavior
Heterogenous ribonucleoproteins (hnRNPs) are a class of proteins initially discovered to protect the nascent transcripts before they develop into primary mRNAs. They are involved in almost all the stages of mRNA metabolism, ... -
Wave Propagation in Bio-inspired Inhomogeneous Waveguides for Impact Mitigation Applications
Decades of research aim to shield structures and people from impact and shock, mitigating damage and traumatic brain injuries. The development of novel structures to absorb energy and reduce stress waves in structures ... -
Bearings-Only Quadrotor Guidance in Gap Traversal Scenarios
In autonomous missions, quadrotors are often required to safely fly through gaps or openings. Designing traversal guidance strategies becomes crucial in such scenarios, especially when the quadrotor relies on the information ... -
Studies on Flexural Fatigue Behaviour of Plain Concrete – Mechanisms of Crack Growth, Effect of Loading Amplitude, Frequency and Notch Size
Concrete structures such as bridges, pavements and off shore structures are subjected to fluctuating loading throughout their service life. These fluctuating loads cause progressive internal damage to structures leading ... -
