Imaging and Spectral Studies of Solar type I Noise Storms at Metric Wavelengths
(Indian Institute of Science, 2005-02-01)Type I noise storms constitute a sizeable fraction of the active-Sun component of solar radiation at meter wavelengths. The storms occur over a prolonged duration as intense, narrow-band spikes, superposed on a low-intensity ... -
Impact of Disorder and Topology in Two Dimensional Systems at Low Carrier Densities
(2018-02-15)Two dimensional (2D) systems with low carrier density is an outstanding platform for studying a wide spectrum of physics. These include both classical and quantum effects, arising from disorder, Coulomb interactions and ... -
Impact of Disorder, Magnetism and Proximity-Induced Superconductivity on Conductance Fluctuations in Graphene

Impact of van der Waals epitaxy on structural and optoelectronic properties of layered solids
Emergence of Graphene, Transition metal dichalcogenides (TMDCs) and other van der Waals materials promises to rede fine the building blocks of the future materials and technologies. These materials have gained enormous ... -
Implications in substrate recognition, catalysis and drug-design Structural basis for neutralization of ribosome-inactivating proteins by their monoclonal antibodies
Cryptic elements of proteins are not visible in unbound structures but become apparent in ligand/substrate-bound structures. These binary states of cryptic elements in protein structures can impact important aspects of ... -
Inferences on Structure and Function of Proteins from Sequence Data : Development of Methods and Applications
(2018-07-23)Structural and functional annotation of sequences of putative proteins encoded in the newly sequenced genomes pose an important challenge. While much progress has been made towards high throughput experimental techniques ... -
Infinitely Divisible Metrics, Curvature Inequalities And Curvature Formulae
(2014-06-30)The curvature of a contraction T in the Cowen-Douglas class is bounded above by the curvature of the backward shift operator. However, in general, an operator satisfying the curvature inequality need not be contractive. ... -
Infrared interaction in surface modified thin film of carbon nanotubes
In the entire study carried out in this thesis work, it has been established that, interfacial interaction of MWCNTs with functional materials like QDs, semiconducting NPs and metal NPs is beneficial towards improving ... -
Insights into Substrate Specificity in Sortase Enzymes from Structural Studies on a Novel Class of Housekeeping Sortase (SrtE) Identifying Functionally Important Cis-Peptide Containing Segments in Proteins and their utility in Molecular Function Annotation
(2018-02-21)Understanding protein function is fundamental to the fields of protein engineering and drug design. While most of the previous efforts in this direction have focused on the sequence-structure-function paradigm, recent ... -
Instrumentation For Reverse Iontophoresis And Biosensor Capacitance Measurement
(2010-09-15)Iontophoresis is a method to enhance and regulate the transdermal drug delivery by application of an electric field to the skin. Application of small electric current (µ A) enhances transport of both charged and neutral ... -
Integrated Gas Sensor - Studies On Sensing Film Deposition, Microheater Design And Fabrication, Interface Electronics Design And Testing
(2015-08-05)Recently, there has been an increasing interest in the electronics world for those aspects related to semiconducting gas sensor (SGS) materials. In view of the increasingly strict legal limits for pollutant gas emissions, ... -
Interplay between the Mechanics of Flexible Substrates and Performance of Thin Film Transistors: Role of Buckled Geometry
Buckled Thin Film Transistor (TFT) resulting from the stress induced instability of thin films realized on a exible substrate can behave di erently than that of a planar device. The aim of this thesis is twofold: To ... -
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, ... -
