X-Ray Crystallograhic Studies On 2',5', Cyclic And Modified Nucleotides
(2007-09-05)
This thesis presents the crystal structures of 2', 5', cyclic and modified nucleosides / nucleotides. Chapter I gives a brief account of the structural studies on 2', 5' and modified nucleotides. It also presents a short, ...
Carrier Mobility And High Field Transport in Modulation Doped p-Type Ge/Si1-xGex And n-Type Si/Si1-xGex Heterostructures
(Indian Institute of Science, 2007-06-26)
Modulation doped heterostructures have revolutionized the operation of field effect devices by increasing the speed of operation. One of the factors that affects the speed of operation of these devices is the mobility of ...
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 ...
Crystal Structure Of Abrus Precatorius Agglutinin-I (APA-I) : Insights Into The Reduced Toxicity Of APA-I In Relation To Abrin. Formation Of Ordered Nanotubes Through Self Assembly In The Crystal Structures Of Dipeptides Containing α. β-dehydrophenylalanine
(2009-07-22)
Ribosome Inactivating Proteins (RIPs) are protein or glycoprotein toxins that bring about the arrest of protein synthesis by directly interacting with and inactivating the ribosomes. Such toxins are in general, of plant ...
Resistance Fluctuations And Instability In Metal Nanowires
(2009-03-13)
The principal aim of this thesis is to study the electrical transport properties of metal nanowires. Specifically, we have focussed on investigating the resistance fluctuations of Ag and Cu nanowires of diameters ranging ...
Contributions To Venominformatics : Sequence-Structure-Function Studies Of Toxins From Marine Cone Snails. Application Of Order-Statistics Filters For Detecting Membrane-Spanning Helices
(2009-07-21)
Venomous animals have evolved a vast array of peptide toxins for prey capture and defense. Nature has evolved the venoms into a huge library of active molecules with high selectivity and affinity, which could be explored ...
Studies of Static and Dynamic Multiscaling in Turbulence
(Indian Institute of Science, 2005-06-17)
The physics of turbulence is the study of the chaotic and irregular behaviour in driven fluids. It is ubiquitous in cosmic, terrestrial and laboratory environments. To describe the properties of a simple incompressible ...
Numerical Studies Of Slow Dynamics And Glass Transition In Model Liquids
(2009-12-16)
An increase in the co-operativity in the motion of particles and a growth of a suitably defined dynamical correlation length seem to be generic features exhibited by all liquids upon supercooling. These features have been ...
Electrical And Magnetic Properties Of Polyvinylchloride - Amorphous Carbon / Iron Carbide Nanoparticle Comosites
(2009-05-18)
The UV-Visible spectra of a-C composites and nano composites have provided a very useful information about the electronic states and band structure. The UV-Visible spectra of a-C as well as nanoparticle are qualitatively ...
Magnetization, Magnetotransport And Electron Magnetic Resonance Studies Of Certain Doped Rare Earth Manganites
(2009-09-03)
Study of rare-earth manganites has been a very active research area in the last few years in condensed matter physics. This is due to the interesting phenomena such as (1) colossal magneto resistance (2) charge, orbital ...
