Particle Dynamics In A Turbulent Particle-Gas Suspension At High Stokes Number
(2010-12-08)Particle laden turbulent flows find applications in many industrial processes such as energy conversion, air pollution control etc. In these types of flows, there are strong coupling between the turbulent fluctuations in ... -
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 ... -
Phase transitions of fluids confined in nanopores
Confined nanoscale fluids occur in many technologically important phenomenon such as boundary lubrication, adsorption, adhesion and catalysis. Fluids confined at these length scales are spatially inhomogeneous and fluid ... -
Photocatalytic and Photoelectrocatalytic systems for water remediation and energy applications
This PhD work consists of two main parts. The first part focuses on photocatalytic systems for water remediation from bacteria and phenolic compounds, and the second part deals with photoelectrocatalytic systems for biomass ... -
Physico-chemical problems relating to the plant required for the manfacture of acetic anhydride from acetone Part I : Thermal cracking of acetone to ketene
Various processes fo r the manufacture of a ce tic anhydride today are by oxidation of acetaldehyde, pyrolysis of a cetic Pie. acid and pyrolysis of acetone. Of these,/^acetone-cracking process seems to be the most economic ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Polymerization in supercritical fluids
The chemical industry has become increasingly aware of environmental concerns over the use of volatile and hazardous organic solvents to synthesize commercial polymers. Attractive properties of supercritical fluids make ... -
Polysterene-based compatibilizers for polymer blending : main chain epoxidation of high molecular weight polystyrene
Polystyrene has often been functionalized for its use in various commercial applications, but most often the reactive functional groups have been substituted on its benzene ring. In the present work, epoxy functional groups ... -
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 ... -
Prediction Of Separation Factor In Foam Separation Of Proteins
(Indian Institute of Science, 2005-07-20)Polyhedral foams offer large gas-liquid interfacial area associated with a small amount of liquid. Therefore, if a solute adsorbs preferentially at the interface, the concentration of the solute in the foam will be greater ... -
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 ... -
Quality-quantity trade off during antibody production and the design of optimal passive immunization protocols
Passive immunization has been used classically to rapidly clear antigen and reduce disease burden. Surprisingly, recent studies have found passive immunization to induce lasting improvements in the humoral response, ... -
Rate Enhancement Of The Catalytic Hydrogenation Of An Unsaturated Ketone By Ultrasonic Irradiation
(Indian Institute of Science, 2005-08-25)The aim of the work was to develop an understanding of the phenomenon of rate enhancement observed when a heterogeneous catalytic reaction system is irradiated by ultrasound. The system under investigation was the catalytic ... -
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials
Refractive-Index-Matched Fluorescent Particle Image Velocimetry for Investigation of Flow in Immersed Granular Materials The ubiquity of granular materials and their importance in everyday life, industry, and nature make ... -
Rheology of Dense Granular Chute Flows
Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ... -
Rheology of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely used in several industrial processes. Characterising the flow of these materials has always proved challenging due to the lack of simple ... -
Rheology of dense non-Brownian suspensions
Suspensions are ubiquitous in nature and industry, ranging from magma, blood, and mud to cement, paint, and molten chocolate. Despite the Newtonian nature of the suspending fluid and the expectation of linearity in the ...
