Energy Loss in Elastic Plastic Low Velocity Impacrt In Presence of Electric Field
Impact phenomena are prevalent in various fields, including the impact between celestial bodies, particle dampers, sports mechanics, and granular media. Impacts between bodies often exhibit inelastic behaviour due to ... -
Robust Fabrication Methods for Solid-state Nanopores
Solid-state nanopores represent a versatile and robust technology for high-precision single-molecule detection, offering distinct advantages over biological nanopores in terms of durability, size control, and integration ... -
Host-Guest Chemistry of Water-Soluble Coordination Cages and their Applications
Host-guest interactions are key to enzyme-substrate recognition, where the enzyme acts as a host, providing a specific cavity for the guest to bind. Inspired by host-guest interactions observed in nature, a significant ... -
Symmetry broken collective electronic phenomena in perovskite titanates
According to Landau’s theory, the organizing principle for understanding phase transitions is rooted in the change in a system’s underlying symmetry, which is quantitatively captured by the order parameter. In strongly ... -
Detection and Dynamics of Electron Bubbles in Liquid Helium-4
Liquid helium surfaces display fascinating phenomena resulting from the interaction be- tween helium atoms and excess electrons. These interactions are characterized by (i) a long-range attraction due to the finite ... -
Development of Scalable UAV Swarm-based Cooperative Search and Mitigation Approaches for Wildfire Management
Climate change has significantly exacerbated wildfire seasons, increasing their frequency, duration, and scale of destruction. Globally, wildfires destroy approximately 400 million hectares of land annually, resulting in ... -
Design and Development of Hybrid Catalyst for Hydrogen Storage: A Demonstrative Concept using Liquid Organic Hydrogen Carriers (LOHCs)
The urgent need to address CO2 emissions resulting from the industrial revolution has placed a strong emphasis on the reduction of greenhouse gases. As a result, hydrogen has gained significant attention as a sustainable ... -
Eco-evolutionary consequences of bacterial predation
Predator-prey interactions pervade all ecosystems at all levels of biological organization. Ample research using higher eukaryotes has demonstrated the role of predator-prey interactions on the evolution of ecological and ... -
Cues for phagosome maturation deciphered using a tuneable particulate system
Phagocytosis, an essential component of the innate immune response, is followed by the process of phagosome maturation inside the cell. Maturation ensures that the engulfed target is delivered to the acidic lysosome for ... -
A Comprehensive Evaluation of High-Temperature Deformation and Damage Behavior of IN740H, a γʹ-Lean Model Ni-Based Superalloy
Advanced ultra-supercritical (AUSC) power plants represent a significant leap in thermal efficiency and environmental sustainability for coal-based energy production. By operating at higher temperatures (≥ 760 °C) and steam ... -
Mitigating Bias via Algorithms with Fairness Guarantees
The rapid integration of automated decision-making systems in critical domains such as resume screening, loan approval, content recommendation, and disaster containment has raised significant concerns regarding biases in ... -
Exploring the Fractional Quantum Hall Effect and Electron-Electron Interactions in ABA Trilayer Graphene through Electric Fields
Since the discovery of graphene (a single sheet of carbon atoms) in 2004, the field has expanded with groundbreaking discoveries like the Quantum Hall effect, correlated phenomena, superconductivity, and ferromagnetism. ... -
Dictionary Based Channel Estimation and Precoding Techniques for Massive MIMO Wireless Communication Systems
Massive multiple-input multiple-output (MIMO) systems constitute a promising enabling technique for 5G/6G cellular networks as a benefit of their substantial spatial multiplexing gain in both time division duplex (TDD) and ... -
Signatures of Co-existing Dual Topological Surface States in Topological Insulators using Scanning Tunneling Spectroscopy and Electrical Transport
Topological insulators host exotic metallic states on their surfaces even when the bulk is insulating. The distinctive conducting surfaces of topological insulators present a novel domain for investigating the physics of ... -
A Geochemical, Sr isotopic, and numerical study of river water, groundwater, and sea water interaction in the tidally dominated Hooghly (Ganga) estuary
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with saline water from the ocean. It is a dynamic system that is characterized by large changes in water chemistry (e.g., ... -
Itaconate Based Dual-reactive Polymeric Coatings and Photo-cross-stitching Studies of Periodically Grafted Amphiphilic Systems
Dual-reactive coatings are those that covalently anchor to the substrate while at the same time permit installation of desired segments in a post-coating step; several approaches have been developed to design such polymers ... -
Proximity-induced superconductivity in a dual topological insulator and crossover from gapped-to-gapless Dirac surface states in a magnetic topological insulator
The combination of non-trivial topology and superconductivity is predicted to give rise to exotic Majorana fermions at the vortex core, forming a topological superconductor (TSC). TSCs, crucial for fault-tolerant quantum ... -
