Title of Research Thesis: :Studies on the Processing of SiBOC Foams from Methylvinylborosiloxane
Abstract: Ceramic foams are versatile materials with properties like chemical inertness, thermal shock resistance, and high-temperature stability. However, their relatively high cost of realisation has been one of the bottleneck in their wide adoption. With the advent of ceramic precursors, especially the low-cost class like siloxanes and borosiloxanes, new opportunities evolve in developing cost-effective ceramic foams from these precursors. The thesis explores some innovative methods to realize SiBOC ceramic foams with methylvinylborosiloxane as a precursor. The techniques utilized include using melamine foam as scaffolds, urea crystals as sacrificial templates, carbon fiber embedding through natural cotton fibers, and aluminosilicate wool as preform. These foams exhibit low density, tunable porosity, and oxidation resistance up to 1300°C, and have the potential for use in thermal protection applications, including re-entry vehicles.

Title of Research Thesis: :Investigation on preceramic polymers for mullite matrix composites and ceramic foams for thermal protection applications
Abstract: Mullite ceramics are widely recognized for their superior thermal stability, good creep resistance, low thermal conductivity and resistance to oxidation in high-temperature oxygen-rich environments. This thesis investigates a polymer-derived ceramic approach aimed at overcoming the limitations of traditional oxide composite manufacturing by enabling low-temperature, pressureless sintering while preserving the integrity of reinforcement materials. In this context, aluminosiloxane and zirconoaluminosiloxane precursors were synthesized for mullite and zirconia-mullite ceramics, and thoroughly characterized. Ceramic conversion studies demonstrated that these precursors can form stable ceramic phases at temperatures as low as 900°C, making them suitable for oxide-ceramic matrix composites (OCMCs). Fibrous alumina-reinforced composites derived from these precursors exhibited exceptional thermal and mechanical performance, including the ability to withstand hypersonic heat flux without damage. Additionally, cellular ceramics produced from these precursors formed open-cell structures with low thermal conductivity, critical for thermal protection applications. The influence of ceramic residue on the density, strength, and thermal properties was also explored. The results underscore the potential of these ceramics in advanced aerospace applications, particularly for thermal protection systems in hypersonic vehicles.

Title of Research Thesis: :Flexible, Electrospun Polyacrylonitrile Based Carbon Nanofiber Composites for Electromagnetic Interference Shielding.
Abstract: Over the last decade, advancements in the electronics sector have raised the bar for EMI shielding requirements. To meet this demand, recent research has focused on developing shielding materials that can give the same level of EMI SE value while eliminating all of the disadvantages of traditionally employed metallic shields. However, there is a significant gap between laboratory-level preparation and industrial applications. In this thesis work, we tried to fill this gap and have suggested simple strategies for preparing water-proof, lightweight, thin, and flexible shielding materials with high- performance EMI shielding in X, Ku, and K-band. Here, carbon nanofibers (CNF) were produced from electrospun PAN by carbonization at 900°C. The obtained CNF mats have inherent nitrogen doping with graphitic structure and 1-D fibrous, porous, and layer-by- layer structure which make them capable of absorbing EM waves. In the first approach, CNF was coated with poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT: PSS) with the assistance of polyvinylpyrrolidone (PVP) to improve the EMI shielding properties. Then, we explored different types of fillers such as inorganic semiconductor tellurium nanoparticles (NPs), Semiconductor metal oxide Nb2O5 NPs, conducting perovskite metal oxide La0.85Sr0.15CoO3 NPs, BaTiO3 NPs, and carbon black NPs, incorporated with CNF to improve the electric conductivity as well as EMI shielding properties. The flexible and hydrophobic polydimethylsiloxane (PDMS) composite of these samples have potential applications in flexible electronic devices as shielding materials for next-generation applications. PDMS allows us to design any type of complex structure, which make it suitable shielding materials for practical applications in different forms such as enclosure, gasket, coating over electronic circuits, and wrapping the electronic components.

Title of Research Thesis: :Novel Nanostructured Multi-Functional Materials for High-Energy Lithium-Sulfur Batteries
Abstract: The realization of a highly developed society with zero-carbon emissions and advanced electrified transportation demands the emergence of batteries delivering superior energy density and charge storage capability. The search of electrochemists to find materials that can outperform Li-ion batteries led to the research on Li-S batteries (LSBs), which are energy-dense, high-capacity energy storage systems. Nonetheless, the widespread development of lithium-sulfur batteries is held back because of some serious concerns. This thesis focuses on developing multifunctional nanostructures as electrode materials to overcome the challenges faced by Li-S batteries (LSBs) and improve the specific capacity. The work introduces a nanostructured graphene-lithium cobalt vanadate-based cathode for LSBs, which delivers excellent capacity with long-term cyclability. Further, studies based on metal sulfide-carbon nanotube-modified separators for LSBs revealed superior electrochemical output with negligible self-discharge. An aqueous processable polymer blend-based cathode binder, which demonstrates better capacity retention and coulombic efficiency over long-term cycling. We envision that this research could provide an effective platform for the emergence of high-performance Li–S batteries.

Title of Research Thesis: :Experimental Characterisation and Numerical Modelling of Planar Cavitating Venturis
Abstract: A cavitating venturi is a passive device that uses hydrodynamic cavitating flow to anchor the mass flow rate. The inter-phase interactions impart inherent cavity oscillations in the venturi operation, presenting challenges in understanding its flow behaviour and developing reliable numerical models. Cavitating venturis are passive devices with no moving parts. This unique feature makes the device an excellent flow rate controller in various industrial applications. Systematic experiments conducted as a part of the project experimentally characterised the nature and dynamics of the cavitation zone in planar cavitating venturi. Predictability limits of the existing two-dimensional models have been assessed using scaling studies in axisymmetric and planar venturis. A simple one-dimensional model has been constituted to aid in the design and sizing of cavitating venturis. An App has been developed based on this model to aid the venturi sizing. The beta version on this App is being evaluated by LPSC, ISRO with the data available from their cavitating venturis in the fuel feed control lines of rocket engines.

Title of Research Thesis: :Optimal Mission Design to Lagrangian Points
Abstract: Scientific missions to Lagrangian points have the potential to enhance the understanding of the universe and to accelerate the exploration of space. A typical mission design to an orbit around the Lagrangian points from the Earth involves two steps. In the first step, an orbit with prescribed geometrical characteristics is designed and in the second step, an optimal transfer trajectory to the orbit from an Earth parking orbit is designed. In the conventional approach to generate the preliminary design, the model of Circular Restricted Three Body Problem (CRTBP) framework is adopted utilizing differential correction (DC) and the transfer trajectory design using manifold theory. In this research, the preliminary design of orbits and transfer to them from the Earth are proposed to be executed under the framework of Elliptic Restricted Three Body Problem (ERTBP) utilizing an evolutionary optimization technique called Differential Evolution (DE). Various periodic orbits and quasi-periodic orbits in the Sun-Earth-spacecraft and Earth-Moon-spacecraft restricted three body systems and transfer trajectories to them from the Earth are generated without leveraging the manifold theory. For the transfer trajectory design in the Earth-Moon system, the proposed two-impulse methodology avoids the bridge segment and generates optimal trajectories with significantly lower flight durations compared to the manifold theory. The preliminary numerical designs are extended to high fidelity ephemeris models. In the ephemeris model, the generated quasi-halo orbits in the Sun-Earth system do not need any theoretical design maneuvers for about five years. For the mission design in the Sun-Earth system, it is substantively concluded that preliminary design using the ERTBP framework does not provide significant advantages over the CRTBP framework due to the near-circular nature of the Earth’s orbit around the Sun. The differential evolution technique is found to be very versatile in solving Lagrangian point mission design problems and avoids many complexities associated with the differential correction based technique. However, the DE based schemes are found to be computationally more intensive. The outcomes of this research can provide valuable methodologies and insights that can significantly enhance the effectiveness of future Lagrangian point missions, thus paving the way for further exploration and scientific discoveries in space.

Title of Research Thesis: : Studies on Adsorbents for Perchlorate Removal from Water
Abstract: Perchlorate contamination in water due to industrial and space activities remains a serious problem as it seriously affects the function of thyroid glands. Various methods are being explored for the removal of perchlorate from the contaminated water. Among them, adsorption is a simple and cost-effective technique. The development of efficient adsorbent materials is the key to the success of the adsorption method of perchlorate removal. This thesis explores the synthesis of magnetically functionalized novel adsorbent materials from bio-waste such as eggshell and watermelon rind. Synthesis of N-doped activated carbon and Metal-Organic- Framework (MOF) based adsorbents are also explored. The perchlorate adsorption efficiency, adsorption mechanism, adsorption isotherm models, and adsorption kinetics are studied with the developed adsorbents. The regeneration of the spent adsorbents using suitable regents is also demonstrated for their reuse. The high perchlorate adsorption capacity of some of the adsorbents demonstrates their potential for practical applications.

Title of Research Thesis: : Investigations on Alumina Ceramic Forming Using Natural Rubber Latex Binder
Abstract: Processing of powders to ceramic components uses a large number of interim additives such as solvents, binders, plasticizers, dispersants, lubricants, and coagulating agents. The majority of these processing additives are synthetically prepared from petroleum-based chemicals. Sustainable development necessitates the replacement of these synthetically prepared additives with naturally renewable materials. The thesis explores the use of natural rubber latex as a binder, gelling agent, and pore stabilizer for the preparation of dense and porous alumina ceramics. Powder pressing, tape casting, slip casting, and freeze-gel casting processes have been established for the preparation of dense and porous alumina ceramics using natural rubber latex binder for the first time.

Title of Research Thesis: : Enhanced Sparsity Order Estimation Techniques for Dynamic Compressed Sensing
Abstract: The work is on Dynamic Compressed Sensing (DCS) system for efficient acquisition and recovery of sparse and compressible time-varying signals. DCS has three key components to be addressed: Estimation of the Sparsity level, indices of those sparse basis functions and their amplitudes. Sparsity Order Estimation (SOE) algorithms based on both Bernoulli/Gaussian sensing matrices and optimal tracking algorithms such as the Kalman filter and Viterbi Algorithm were developed. The developed algorithms resulted in reducing the complexity of CS methods by 25-30 % taking them closer to practical realization.

Title of Research Thesis: : Investigation of Generation mechanisms of the post-midnight F- Region Irregularities
Abstract: The work presented in this thesis is a theoretical and numerical investigation of the spin- dynamics in two recently demonstrated experiments involving long periods of RF irradiation on the quadrupolar nuclei channel, the 1 H - 14N double cross polarization (double CP) under fast MAS experiment by Carnevale et al. and the 1H - 35Cl TRAPDOR-HMQC experiment of Hung et al. Creation and evolution of various coherences generated in these proton-detected experiments are explored. To analyse the rich and complex spin dynamics due to the interference between the large time-dependent quadrupolar interaction and the radio-frequency (RF) field, an exact effective Hamiltonian is constructed numerically using the matrix logarithm approach. Structure of the effective Hamiltonian is connected with transfer amplitudes to various coherences, the output signal, etc. and, when possible, features of the spin dynamics are derived theoretically. The analysis also provides insight on the efficiency of these experiments under different experimental conditions.

Title of Research Thesis: :Spin dynamics at fast MAS in ¹H -¹⁴N double cross -polarization and TRAPDOR - HMQC experiments involving spin 3/2 nuclei
Abstract: Experiments probing correlations between spin-1/2 nuclei (I) and nuclear spins (S) with large anisotropic interactions (quadrupolar or chemical shift anisotropy ) often offer valuable access routes to molecular structures and dynamics. In such experiments, development of efficient correlation schemes is not trivial and constitutes an ever-evolving theme of research. As these experiments are performed routinely under MAS, interference between the RF filed and the large time- dependent quadrupolar or chemical shift anisotropic interaction leads to complex spin dynamics, often leading to poor and orientation-dependent transfer efficiency.

Title of Research Thesis: : Non linear and non classical properties of deformed quantum states
Abstract: We begin our work by studying the most general class of oscillators, called ‘f-deformed oscillators’ or ‘f-oscillators’. We define the quadrature operator for the f-deformed algebra and hence obtain the deformed quadrature operator eigenstates. We derived a new set of polynomials and derived the deformed oscillator wavefunctions in terms of them. The position probability distribution for three different types of deformations are plotted, and each is compared with the corresponding non-deformed counterpart. The newly obtained quadrature operator eigenstates will be helpful for those who are working in the field of quantum state reconstruction and quantum information processing of deformed states.

Title of Research Thesis: : Design, development and fabrication of Gallium Nitride (GaN) High Electron mobility transistor (HEMT) based terahertz devices for space applications
Abstract: This dissertation is explored the photonics inter sub band transitions (ISBT) phenomenon in an electronics Gallium Nitride (GaN) high electron mobility transistor (HEMT) device. Conventional photonic devices are operated at cryogenic temperatures to minimize the thermal effect. The reported maximum operating temperature of THz quantum cascade laser (QCL) is in the range of 150-200 K which is too low for general applications. The conduction band tuning through external gate bias makes advantage of HEMT device for room temperature (RT) terahertz applications. The theoretical models for electrically tuneable plasmonic metamaterials assisted ISBT have been developed. Experimental demonstration of electrical tuning of ISBT in a GaN HEMT device at room temperature has not only provided a novel mechanism but also discriminates ISBT from other transitions induced by deep-level traps and defects in the 100 nm GaN HEMT device. It is possible to tune the subband energy level inside triangular quantum well of GaN HEMT by applying gate voltage. The GaN HEMT device responds toward incident terahertz radiation due to inherent advantage of conduction subband tuning through external bias. The presented novel approach for ISBT in GaN HEMT has the potential possibilities in the context of overcome the THz gap in the electromagnetic spectrum at ambient temperature.

Title of Research Thesis: : Graphene Quantum Dot and Metal Nanocluster-Based Nano Functional Materials for Electrochemical Sensing Applications
Abstract: Electrochemistry deals with the relation between electrical and chemical phenomena and has an ever-increasing impact on everybody's daily life. Out of the myriad applications of electrochemistry, considerable attention has been devoted to the fields of electrochemical (EC) sensing in recent decades because of its inherently fast, accurate, compact, portable, and cost-effective properties. In this scenario, the thesis work aims to address the challenges in the fields of EC sensing by using the rational design of nano-functional materials using graphene quantum dots (GQDs) and metal nanoclusters (MNC). The on-site monitoring of various analyte species in the environment by EC sensors requires enhanced sensitivity, specificity, and accuracy. Herein, we are trying to meet the aforementioned needs by developing various nano-functional materials based on GQDs and MNC. We have developed nitrogen (N-) and sulphur (S-) doped GQDs and gold (Au) and copper (Cu) -based NCs for the EC sensing of toxic heavy metal ions and biologically relevant molecules. The EC sensor materials exhibited excellent sensitivities and lowest detection limits reported hitherto, indicating the potentiality of the developed materials. In conclusion, this thesis presents an understanding of how the logical designing of nano-functional materials can meet the needs and conquer the challenges in the EC sensing of various analytes.

Title of Research Thesis: : Lyapunov Based Stable and Robust Adaptive Control Design for a Class of Space Transportation Systems (Jan 2023)
Abstract: First phase of the research work focuses on dynamic modeling and ascent flight control of a highly unstable and flexible launch vehicle. Stabilizing adaptive PD/PID controllers are developed in MRAC framework using standard quadratic Lyapunov function to control the time varying rigid body dynamics during the atmospheric phase of flight. Further, Lyapunov stability and Barbalat’s Lemma are applied to prove the stability of the time-varying system. In the second phase of the research work proposes projection and barrier Lyapunov based adaptive controllers for the descent phase flight control of a winged re-entry vehicle. A rectangular projection operator is used in the adaptive control design to constrain the adapted gains within a maximum and minimum limit simultaneously.

Title of Research Thesis: : Analysis of Failure Mechanisms and Mechanical Properties of Hierarchical Bio-inspired Composites
Abstract: Nacre, bone, spider silk, and antlers are some examples of biological composites that exhibit a great combination of mechanical properties such as high strength, stiffness, and toughness when compared to that of their constituents using which they are made up of. This has inspired many researchers to investigate bio-inspired composites to explore the possibilities of making synthetic composites with superior mechanical properties using relatively weaker constituents. There are many reasons behind the achievement of a biological composite’s superior mechanical properties, which range from the selection of constituents to its final arrangement. The basic structure of the above-mentioned biological composites is a kind of brick-and-mortar structure in which platelets with a defined configuration are dispersed in a pool of matrix. Here, the parameters significantly influencing the final mechanical properties are Young’s moduli ratio of platelet to the matrix, the platelet aspect ratio, and the arrangement of platelets, especially the hierarchy. The present study focuses on two staggering types found in nature, regular and stairwise, and conducts a failure analysis on one-hierarchical composites with these configurations. The inclusion of the first failure in the analysis is found to contribute to composite toughness significantly. Case studies using industry materials and recent research works support these findings. Analytical models are formulated for predicting the properties of non-self-similar two hierarchical composites, demonstrating good agreement with finite element analysis results. The generalized model aids in simplifying the design process, providing initial estimations of mechanical properties for hierarchical composites before full-scale fabrication and offering practical insights for future material design.

Title of Research Thesis: : Investigations on Micronozzle for Satellite Propulsion and Gas Mixture Separation.
Abstract: Due to the increased use of cube- and nano-satellites, the demand for micro-propulsion systems has grown, necessitating the optimization of micronozzle design and efficiency. Research on the flow characteristics of micronozzles is currently centered around micro-thruster applications, with the primary objective of achieving uniformity in the flow structure to ensure optimal thruster performance. Conversely, the secondary application involves gas mixture separation, requiring a highly non-uniform species distribution in the flowing mixture. The flow through micronozzles can encompass multiple scales, including continuum, slip, transition, and rarefied gas regions due to their smaller dimensions. The current research commences with numerical studies related to the thruster applications of micronozzles, utilizing classical N-S with a linear slip model, DSMC method, and a hybrid N-S/DSMC based on the continuum breakdown concept. The impact of geometric factors such as the divergence half-angle, throat depth, and expansion ratio is thoroughly analyzed for planar micronozzles, along with considerations of wall temperature conditions. The work also explores the effects of micronozzle geometry and flow parameters on the aerodynamic species separation within a planar nozzle, incorporating linear, bell, and trumpet divergent sections under the presence of carrier gas and back pressure conditions. Subsequently, these studies are extended to include a curved nozzle. The results of this research are anticipated to contribute to the development of improved designs for micronozzles utilized in satellite propulsion and aerodynamic separation processes.

Title of Research Thesis: Direct numerical simulation of flow instabilities in variable velocity flows.
Abstract: Transitional flows with an unsteady inflow play a vital role in a broad range of applications, including biological fluid transport to space applications. In such cases, the thickness of the boundary layer formed over the solid surface varies in both space and time, causing a high level of complexity in the path of vortical structures formed from the shear/boundary layer. Also, time and space-dependent shear stress exerted by the fluid, separation, and associated instability phenomena are to be better understood. In this work, direct numerical simulations (DNS) are performed to study the stability of vortical flow structures associated with an unsteady boundary layer under an adverse pressure gradient condition. A trapezoidal pulse of mean velocity, consisting of the acceleration phase from rest followed by the constant velocity phase and deceleration phase to rest, is imposed at the inlet of the computational domain. The impact of the spatial and temporal components on the evolution patterns of the shear-layer and three-dimensional instabilities are examined in detail. By employing dynamic mode decomposition, some key features of the transitional flow and their time dynamics are extracted.

Title of Research Thesis: Accretion Scenario of Black Hole X-ray Binaries During Outburst.
Abstract: Black hole X-ray binaries (BH-XRBs) are gravitationally bound associations of a compact object (black hole) and a normal star. The compact object can `accrete' matter from the companion star forming an accretion disk which releases tremendous energy, predominantly in X-rays. The stages of sudden bursts of X-ray activity in these systems are commonly known as 'outbursts'. The present thesis endeavours to comprehend the accretion process underlying the exceptionally bright outbursts observed in the two galactic BH-XRB sources: MAXI J1820+070 and 4U 1543-47. The investigation utilizes a wideband spectro-temporal analysis, employing multi-instrument X-ray data. The findings of this study propose the presence of a complex corona geometry (extending both radially and vertically) for MAXI J1820+070 during the 2018 outburst. Additionally, our research reveals a remarkably strong and dynamic absorption feature between 8-11 keV in the 4U 1543-47 spectra. This detection represents the first occurrence of its kind in X-ray binaries. We hypothesize that this feature arises due to the absorption of accretion disk photons by a highly ionized, relativistic disk wind, which attains speeds up to 30% of the speed of light.

Title of Research Thesis: Effects of dilution on the Laminar Burning Characteristics of Oxy-Dodecane mixtures with and without Hydrogen blending and Oxy-Methane mixtures at elevated operating conditions.
Abstract: N-Dodecane plays a crucial role in surrogate fuels for gasoline and jet fuels. Selecting the right surrogate fuel combination depends on the properties of its individual components. Precise reaction mechanisms are essential to predicting combustion characteristics, including laminar burning velocity and ignition delay times. Unfortunately, data for n-dodecane-air, oxy-n-dodecane with diluents like N2, CO2, H2O, and n-dodecane-H2-air are scarce in the literature. This study aims to bridge this gap. It measured unstretched laminar burning velocity under various conditions using a new cuboidal combustion chamber with optical access and a dedicated heating system. The study used the partial pressure method to prepare combustible mixtures, an electrical spark-ignition system for ignition, and high-speed shadowgraph imaging for flame propagation. A non-linear stretch extrapolation scheme determined unstretched flame speed, and the validation process compared the results with existing data. Finally, simulations using CHEMKIN provided insights into the unstretched laminar burning velocity.

Title of Research Thesis: Protostellar jets: Numerical modeling and observational studies.
Abstract: Protostellar jets are fossil records of the accretion history of protostars. Studying these jets opens up an indirect window of knowledge into the evolutionary stages and activities of the protostar, the direct study of which is difficult due to its highly embedded nature. The research highlights a theoretical and observational study of protostellar jets in radio and near-infrared wavelengths, respectively. The first part of the thesis describes a numerical model for radio jets from protostars, having simplistic geometry, which has been developed for the first time to explain the presence of thermal free-free and non-thermal synchrotron emission in these jets. The model has been successfully employed to estimate relevant physical and micro-physical parameters of protostellar jets for which observational data is available. The second part of the thesis covers a near-infrared investigation aimed at exploring the partially ionized and molecular regions of a massive protostellar jet, HH80-81, by utilizing molecular H2 and [FeII] emission lines as shock tracers. This is the first time detection of these emission lines towards the HH80-81 jet and following this, a qualitative and quantitative analysis of the jet has been carried out, enabling the identification of the nature of shocks and estimation of relevant physical parameters of the protostar and its jet.

Title of Research Thesis: Self-excited oscillations in low-density round and rectangular jets.
Abstract: The present study focuses on experimental techniques to understand the self-excited oscillation characteristics in low-density round for fully developed and turbulent flow conditions, as well as rectangular jets, and study the effects Reynolds number, momentum thickness, density ratio and aspect ratio on self-excited oscillation. Two global modes exist in low-density round jets. The results confirms that oscillations in low-density round jets are axisymmetric irrespective of S and D/θ, and turbulent jets can exhibit self-excited oscillations for S ≤ 0.53. Studies on rectangular low-density jet reveal that the jet transitions from a stable to a self-excited state through subcritical and supercritical Hopf bifurcation. Only supercritical bifurcations are observed during transition when AR ≥ 12. For lower aspect ratios, the type of Hopf bifurcation is dependent on the density ratio. SPOD analysis of low AR rectangular jets (AR ≤6) show that the spatial structure of the oscillation is a symmetric mode. SPOD analysis reveals that the spatial structure of the oscillation in high AR rectangular jets (AR ≥ 12) consists of three modes: a symmetric mode, a flapping mode in the major dimension and a complex mode similar to the ce2 mode in elliptic jets.

Title of Research Thesis: Experimental Studies of Selective Catalytic Reduction of NOx with NH3 on Cu-ZSM-5 Foam Catalysts.
Abstract: Selective Catalytic Reduction (SCR) is one of the most promising technologies for reducing after-exhaust NOx emissions. Cu zeolites generally provide high SCR conversion rates at temperatures ≤ 350◦C. The limitations associated with powdered catalysts, such as low mass diffusion and high pressure drop, can be minimized to a certain extent by replacing them with structured catalysts. The foam catalysts exhibit superior characteristics, such as a high surface-to-volume ratio, porosity, and tortuosity, which improve the mass diffusion and lower the pressure drop. In this study, α-alumina foam was prepared using a thermo-foaming technique. The procedure followed during this research for the preparation of the Cu-ZSM-5 zeolite coating over alumina foam through in situ hydrothermal and dip-coating methods is also presented in detail. A self-supporting foam catalyst of Cu-ZSM-5 is prepared using a freeze-casting emulsion method. A comprehensive experimental study was conducted to understand the mass transfer and pressure drop characteristics of the foam catalysts. Correlations for the mass transfer coefficient and friction factor were derived for the foam catalyst and validated against the available data in the literature reviewed. A detailed investigation of key SCR reactions, such as the standard SCR, fast SCR, slow SCR, NO oxidation, NH3 oxidation, and NO2 decomposition, was also carried out in this research. The inhibitory effects of the feed reactants were studied by varying the feed concentration. A detailed investigation of the impact of the inhibition effect of NO2 and NH3 on the SCR reaction at low temperatures is also presented.

Title of Research Thesis: Development of novel stochastic meshless methods for linear and nonlinear problems in structural mechanics.
Abstract: The current work proposes novel stochastic meshless methods for the analysis of linear and nonlinear problems in structural mechanics which can take care of uncertainties in material property and loading when they appear as random variables or homogeneous random fields. The study suggests an improved response function based stochastic meshless method for the analysis of linear elastic problems. Further, the study also proposes a simple and efficient stochastic meshless method for the analysis of linear eigenvalue problems in structural mechanics. A high dimensional model representation based stochastic meshless technique is proposed in the current study for the analysis of geometric nonlinear problems in solid mechanics. A few numerical examples are solved to validate the proposed method by comparing the results with the direct Monte Carlo simulation or other existing methods.

Abstract: Defect free machining of Fibre Reinforced Polymer (FRP) Composites, crossing the challenges posed by anisotropic non-homogenous fibre-matrix system, is one of the important material processing requirements with a wide scope in industrial applications. Eccentric Sleeve Grinding (ESG) projected in this research is a unique strategy with progressive-intermittent cutting scheme for achieving minimal damage machined surfaces on FRPs. Progressively varying depth of engagement for active abrasive grains in the cutting zone with an intermittent and periodically repeating cutting pattern, achieved through precisely controlled eccentric rotation of grinding wheel is the key highlight of ESG. Through this step-by-step cutting methodology, significant reduction in average grinding force, surface defects and surface roughness have been achieved on Carbon Fibre Reinforced Polymer (CFRP) composites under varying cutting conditions. The thesis covers the geometric configurations, kinematics, coordination of work feed and wheel rotation to achieve scallop free surfaces during intermittent cutting, theoretical and experimental studies on mechanics and micro-mechanics of ESG, thermal aspects and other miscellaneous findings (theoretical and experimental) on ESG.

ARIS (Advanced Retarding Potential Analyser for Ionospheric Studies) is an ionospheric plasma and electrostatic instrument developed by IIST for the structural and compositional studies of the ionosphere. Solar activity which is the main driver of the ionosphere can be studied in real-time by performing ion and electron density measurements in the ionosphere. Such measurements provide us with the warning of hazardous radiation effects on space assets, possible radiation exposure to aircraft crew and possible power grid disruptions. Therefore, real-time and constant monitoring of ionospheric behaviour is of great importance to humans in day-to-day life
ARIS 201F was launched on PSLV C55 on the PS4 stage. ARIS 201F is an upgraded version of ARIS 101F which was flown to Earth’s ionosphere in 2019 as part of the PSLV C45 mission. ARIS 201F has fully indigenous and in-house-built sensors with high sensitivity and high energy resolution and optimised operating parameters to receive more data in the energy range relevant to the Earth ionosphere (based on data received from ARIS 101F). The payload uses a Dual-Retarding Potential Analyser (RPA) configuration, Ion-mode RPA (I-RPA) and Electron-mode RPA (E-RPA) along with four electronics cards (Pre-amplifier board, front-end electronics board, data acquisition board and power generation board).

Pslv-In-orbitaL Obc and Thermals (PILOT), is a payload designed for the fourth (and final) stage of PSLV with the aim to achieve thermal model validation and flight qualifications for the in-house developed On-board computer, which is expected to fly in multiple upcoming missions developed at SSPACE. The payload carries a number of temperature sensors which are used to collect valuable thermal data for thermal model validation of various subsystems in LEO. The PILOT payload has a volume of ~1U, and a mass of less than 1kg. The bus is designed to work on less than 0.5W power. The power and telemetry of the payload is through PSLV stage 4. The payload has been succesfully launched in PSLV C55 on April 2023.
PILOT is an unique mission from IIST

Testing of Assembled Subsystems
With the goal of in-situ radiation dosimetry, SSPACE (Small-spacecraft Systems and PAyload CEntre), IIST Thiruvananthapuram, India, is developing a constellation of 3U CubeSats with AHAN as the first in this series expected to be launched by 3rd quarter of 2023. The CubeSat is about 2kg in mass with a nominal power consumption of about 3 Watts. The CubeSat houses a Geiger-Muller Counter for radiation dosimetry, which serves as the payload. The satellite is developed with all in-house subsystems which will also serve the purpose of flight validation of the subsystems.

Small-spacecraft Systems and PAyload CEntre (SSPACE) is an interdisciplinary centre involved in the development of satellite systems and mainly driven by students and faculty of IIST. The SSPACE center is involved in realization of payloads, related electronics, small satellites, assembly, integration, testing and ground station to carryout mission operations. SSPACE at the moment is involved in the following missions
The IIST ground station can operate in the UHF for telecommand and telemetry of the INSPIRESat-1 at 9.6kbps. The S-band is exclusively used for receiving the data from the payload at 2Mbps. IIST built a ground station in the UHF and S-band for telemetry, telecommand and data reception from the spacecraft. IIST took the responsibility of owning the spacecraft. In addition, IIST with active support from VSSC developed the advanced separation system and sought mission opportunities as a co-passenger through ISRO’s workhorse PSLV mission. IIST students participated in the documentation of operational activities for pre-launch operations at the launch site in a cleanroom environment and subsequently participated in the mechanical integration of the spacecraft to the vehicle. The end-to-end activities from conceptualisation to realisation to operationalisation created industry-ready students.
