Kinetics of Photocatalytic Degradation of Dyes, Organics and Polymers using Nanomaterials
The main objective of this thesis was to investigate the application of photocatalysis for the degradation of organics, dyes, polymers, reduction of metal ions, decomposition of NO, etc. In this context, extensive work was ... -
Phase Behaviour of Oppositely Charged Nanoparticles : A Study of Binary Nanoparticle Superlattices
Binary nanoparticle superlattices or BNSL’s have been a major area of research in nanotechnology for the last decade. The conventional lithographic techniques are limited to fabricate features only within a plane while ... -
Concentration Gradient Driven Natural Convection in Soluble Lead Redox Flow Batteries
Low cost and long cycle-life energy storage systems are needed to harness renewable sources of energy at large scale. Among the options available, redox ow batteries (RFB) offer the maximum potential. The vanadium based ... -
Exploring water dynamics and gas separations in graphene oxide surfaces and nanopores
Graphene oxide (GO) is a chemically functionalized graphene with various oxygen-containing functional groups, such as epoxy (-O-), hydroxyl (-OH), and carboxyl (-COOH) on the basal plane. As a consequence, GOs have hydrophilic ... -
Studies on a New Spinning Disc-Spinning Bowl Contactor/Mixer
Increased focus on continuous synthesis of fine chemicals and pharmaceuticals has led to resurgence of process intensification. In this thesis we introduce a new continuous contactor. It works on the principle of impinging ... -
Analysis of the Flow of Granular Materials through a Screw Conveyor
Screw conveyors are widely employed in industry for the bulk transport of particulate materials. Several studies have attempted to correlate the discharge rate with the rotation speed of the screw via experiments and ... -
Processing mediated polymorphism in PVDF-based dielectric polymers and their application
The ever-increasing demand in electronic devices, piezoelectric materials such as ceramics, polymers and polymer ceramic composites with enhanced piezoelectric and dielectric properties has become the focus of many ... -
DNA-based fluorescent reporters for biosensing and lipid dynamics
With the growth of DNA nanotechnology, significant efforts have been made to expand the chemical functionality of DNA beyond the genetic code carrier. By leveraging the specificity of the interactions and modularity afforded, ... -
Non-catalytic synthesis of biodiesel and solubilities of mixtures of lipid derivatives in supercritical fluids
The fossil fuels are depleting rapidly as the demand for energy and its allied chemicals is continuously increasing in the modern world. In addition, the concerns over climate change due to the greenhouse gases emitting ... -
Molecular Analysis of the Pore Forming Mechanism of an α-Helical Cytolysin
Pore forming toxins (PFTs) are lytic membrane binding proteins that are ubiquitous across the animal kingdom and disrupt the structural integrity of the host cell membrane. A unique characteristic of these toxins is that ... -
Modelling and optimization of novel therapies for HIV and hepatitis C virus infections
Curing infections by HIV and hepatitis C virus (HCV) have remained a challenge for a long time due to their efficient ways of evading host immune responses and therapies. They do so by rapidly mutating their genomes, which ... -
Structure and Dynamics of Fluids Under Nanoscale Confinement
Fluid molecules confined between solid surfaces separated by a few nanometers are of considerable interest in nanoscience and nanotechnology as they undergo structural and dynamical transitions absent in their corresponding ... -
Modelling and Experimental Studies on Dynamic Behaviour of Electrochemical Double Layer Capacitors
lectrochemical double layer capacitors (EDLCs) can store and deliver electrical energy at high power density with long cycle life, and can absorb peak charge/discharge loads. EDLCs can be used with batteries to insulate ... -
Synthesis of Thermally Stable Catalysts for Methane Reforming and CO Abatement
The global energy consumption is estimated to reach around 262×1012 kWh/year by 2050 for 9 billion people. It is a challenge to meet global energy requirement via clean fuel (hydrogen) and by reducing/utilizing the CO2 ... -
Pore Forming Toxins : Unravelling Oligomerization Pathways and Related Kinetics
Pore forming toxins are a class of proteins secreted from a wide variety of pathogens. These toxins are implicated in several diseases such as cholera, anthrax, tuberculosis and food poisoning. The toxin proteins are ... -
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 ... -
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 ... -
Improved Theory of Clathrate Hydrates
(2018-07-30)The current theoretical understanding of thermodynamics of clathrate hydrates is based on the van der Waals and Plattew (vdWP) theory developed using statistical thermodynamics approach. vdWP theory has been widely used ... -
