Bubble and conical forms of vortex breakdown in swirling jets
The present study focusses on vortex breakdown (VB), which occurs in axially convected swirling flows and is characterized by the development of an internal stagnation point and regions of reverse flow. VB has been ... -
Carbon aerogel supported first-row transition metal catalysts for methanolyis of ammonia borane
Ni-Ni3B, Co-B, and Co-Ni-B nanocomposites decorated on carbon aerogel were successfully synthesized by adopting the solution impregnation method. The nanocomposites were characterized by powder XRD, transmission electron ... -
Cerium Oxide Based Active Catalyst for Green Hydroxylammonium Nitrate (HAN) Fueled Monopropellant Thruster
Monopropellants are widely used for propulsion and gas generation applications. The current state of art monopropellant systems are based on hydrazine propellants. While hydrazine has a strong heritage as a versatile ... -
Characterization of Brain Signals Across Scales Using Temporally Modulated Visual Stimuli
Electrical signals from the brain can be recorded at several different scales, ranging from spiking activity to local field potential (LFP) in animals to scalp electroencephalogram (EEG) in humans. Each signal represents ... -
Characterization of high enthalpy flows in the IISc free-piston driven shock tunnel using Two-Colour Ratio Pyrometry
High temperature and its associated effects set the hypersonic flow regime apart from other class of flows. Viscous dissipation raises the internal energy of the high-kinetic-energy gas as it slows down in the boundary ... -
Charge and Heat Transport in Low-dimensional Quantum Systems
Transport of electrons through low-dimensional quantum conductors like nano-junctions has been actively pursued research area for the last few decades. Experimental studies on nano-junctions are nowadays routinely carried ... -
Charge transport in functionalized carbon nanotube and composite with polyaniline at low temperature
Carbon nanotube (CNT) is a very well-known material with very high thermal conductivity, high Young modulus and high electrical conductivity. The sp2 bonded C=C π-electrons delocalize in the whole lattice give rise to high ... -
Co-continuous microstructures through spinodal decomposition in ternary systems: A phase field study
We have studied spinodal decomposition which leads to a three-phase microstructure in ternary alloys using computer simulations based on the ternary Cahn-Hilliard equations. All the alloys we have studied are in the same ... -
Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ... -
Compositionality of letter shape in word recognition
As you read this sentence, your brain just performed a miraculous task of converting collections of letter shapes into meaning. Reading is a cultural invention that is thought to exploit the intrinsic recognition abilities ... -
Computational studies on interacting proteins with special reference to toxin-antitoxin systems
Proteins interact with other proteins to maintain functional homeostasis of the cell by tightly regulating cellular processes. Hence, it becomes important to understand not only the downstream effects of protein-protein ... -
Conceptualisation, Development and Validation of Energy Internet for a Transitioning Electricity System
Globally, the national electricity systems are in the midst of aggressive transitions. A shift from large-scale conventional fossil-fuel based power generation systems to large number of small-scale distributed renewable ... -
Condition-dependent signalling and mating behaviour in the tree cricket, Oecanthus henryi
Male reproductive success in systems exhibiting sexually selected traits can be driven by male mating effort in sexual signals and in the production of nuptial gifts. Male mating effort can be determined by various biotic ... -
Conformal Electronics on Elastomers: Packaging Methods and Design Rules
Flexible Electronics is a multi-disciplinary domain that creates intersections among elec- tronics, materials-science, mechanics, packaging, sensor-design, etc., to build exible / stretchable / conformal electronic ... -
Constrained Adaptive Control of Nonlinear Systems with Application to Hypersonic Vehicles
Constraints in input, output, and states are evident in most of the practical systems. Explicitly incorporating these constraints into the control design process leads to its superior performance in general. Therefore, ... -
Control of shock-induced vortex breakdown in Transonic regime on a slender delta wing body configuration using blowing
Modern high speed aircrafts feature highly swept and low aspect ratio wings, mainly to increase the critical Mach number and reduce the wave drag. A special case of swept wings is wings with triangular planform commonly ... -
A Control Systems Approach to Understanding Saccadic Eye Movements
The oculomotor system is extensively studied using concepts of control theory like optimal control, feedback control, and predictive control. But these studies have largely been restricted to investigating the central ... -
Cooling, heating and gas evolution in the circumgalactic medium
The Universe at large scales consists of gravitationally bound dark matter halos. Ordinary gas inside the halos emits and also absorbs the radiation from background sources leaving distinct signatures for multi-wavelength ... -
Corporate Sustainability in India : Analysis of Business Performance in the Context of Climate Change Risks and Opportunities
New standards, regulations and expectations of transparency from various stakeholders are forcing corporate sustainability strategy to move into the mainstream demanding the businesses to become proactive and de-risk ... -
