Engineering Graphene Oxide Surface Chemistry and Investigating Its Effect on The Physicochemical and Biological Properties
In the current study, systematic tuning of oxidation degree of GO has been explored and a two-step methodology for engineering GO surface chemistry was successfully developed. The investigation of the effects of oxidation ... -
Analysis of Laterally Loaded Piles in Clayey Soils with Sloping Ground
In the present study, a small scale 1-g model test has been developed in the laboratory to study the behaviour of a long flexible single pile embedded in a slope of soft clay with different slope angles and L/D ratios, and ... -
Theoretical studies of chemical dynamics in complex systems: Nanoconfined water, microdroplets, biomolecular hydration layer, and water-mediated protein association
The thesis contains theoretical studies of the structure and dynamics in different complex systems. Depending on the systems and properties of interest we divide the thesis into five parts. In the first part, we study ... -
A Fast Constant-Time Approximation for Locally Adaptive Bilateral Filtering
Smoothing is a fundamental task in low-level image processing that is used to suppress irrelevant details while preserving salient image structures. The simplest smoothing mechanism is to average neighboring pixels using ... -
Understanding the Significance of Ydcp, a Putative Peptidase Encoding Gene, in Virulence of Salmonella
Salmonella is a recognised enteric pathogen which infects several mammalian and avian hosts through faeco-oral route and establishes either a localised gastrointestinal inflammation and diarrhoea or a systemic fever, ... -
Wireless Channel Modeling for Drone to Ground 2.4 GHz link
Use of Drones for communication is picking up the pace and expected to grow exponentially in the coming years. These drones will be used as access points for providing WiFi services in the near future. It is well known ... -
Design of broad-band backend compatible photonic devices and vertical inter-layer couplers
Optical interconnects are regarded as efficient replacements for conventional electrical wiring for realizing large data capacity, high-speed transmission and Silicon-based integrated photonics is the best candidate for ... -
Ab-initio Modeling and Designing of Materials for Thermoelectrics, Optoelectronics and High Temperature Applications
Designing a material for a particular application requires an atomistic understanding of its properties. Recent development in first principles methods and supercomputing speeds has enabled researchers to compute materials ... -
Heterogeneous Integration of Thin-film Germanium on Silicon and Steel
Integration of germanium (Ge) on low cost substrates such as silicon and steel open several applications such as low cost III-V photovoltaics, beyond silicon CMOS and optoelectronics applications. However, growth of germanium ... -
Nonpolar III-Nitrides Optoelectronic Devices by Plasma-Assisted Molecular Beam Epitaxy
III-Nitrides are excellent semiconductors very much suitable for modern electronic and optoelectronic applications specifically in the fields of solid-state lighting, solar cells, high power/frequency electronics and ... -
Co-solvent Induced Protein Collapse and Folding
An unfolded protein under favorable conditions navigates its complex energy landscape on a time scale of milliseconds to seconds and folds into a specific three dimensional structure. The mechanism of protein folding is ... -
Interplay of Interaction and Topology From Topological Band Theory to Topological Field Theory
Classification of phases of matter has long been a central point of interest in the research community in condensed matter physics. Over the past several decades mainly two kinds of classification schemes have emerged, ... -
Towards Designing PCM-Conscious Database Systems
Phase Change Memory (PCM) is a recently developed non-volatile memory technology that is expected to provide an attractive combination of the best features of conventional disks (persistence, capacity) and of DRAM (access ... -
Continuous-Wave Supercontinuum Generation using Cascaded Raman Fiber Lasers
This thesis explains architecture and techniques to generate high power, CW supercontinuum laser sources using standard Silica fibers as the nonlinear medium, pumped using high power CW Yb doped fiber lasers. Unlike the ... -
Understanding the demixing behavior and structure-property correlation in graphene oxide containing LCST blends
A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ... -
Improving Data Center Utilisation by Reducing Fragmentation
Virtualization enables better server consolidation and utilisation compared to stand-alone servers running a single workload. This enabled wide-spread cloud adoption among many organizations. Data center utilisation is ... -
Continuum Analysis of Cavitation Induced Failure and Tensile Deformation Response of Metallic Glasses & Nanoglasses
Metallic glasses (MGs), which are metals solidified in an amorphous state, have shown attractive mechanical properties such as high strength (up to 5 GPa), yield strain (around 2%) and good corrosion resistance. They ... -
Diversity and Structure-Property Correlation in Disordered Multicomponent Organic Crystal Forms
The search for new multifunctional materials continues unabated, and with the realization that in solids, the material property can be tailored using the variability provided by molecular and submolecular forces. Harnessing ... -
Microwave synthesis of superparamagnetic cobalt-ferrite thin films for RF CMOS applications
In the era of 5G technologies, the emphasis is on getting all the devices, active or passive to work in high frequencies. Higher efficiency chips can be obtained by combining both the active and passive devices on a single ... -
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavy-flavour mesons as well as of direct photons, has been used to constrain the gluon density inside the proton. In this thesis, I have assessed various heavy flavour ...
