Curvature Generation in Self-Assembled Fluid Membranes
The ability of thin sheets to curve into complex three-dimensional shapes underlies diverse biological processes. We study curvature generation in fluidic membranes using the model system colloidal membrane, which is ... -

De Novo design of protein secondary and super-secondary structural elements : Insights from the crystal structures of a,B-dehydrophenylalanine containing oligopeptides- a novel weak-interaction based design strategy
The surface complementarity (charge, structural, etc.) plays a vital role in molecular recognition and association. It appears that the modes of interaction between aliphatic–aliphatic, aliphatic–aromatic, and aromatic–aromatic ... -
Dendrimer Interactions with Cell Membrane and Pore Forming Toxins
Dendrimers are hyper-branched polymeric nanoparticles with a central core molecule connected by successive dendritic branching layers. The structure controlled parameters of den-drimers such as size, shape, surface chemistry, ... -
Density functional and computer simulation studies of colloidal suspensions
Colloidal suspensions of polyballs (polystyrene spheres) are good model systems for the study of both structural and dynamical properties of solids and liquids because the pair-wise interaction between the colloidal particles ... -
Design and construction of a pulsed high magnetic field facility and high field magnetoresistance studies in some semiconductors
Negative magnetoresistance at 77?K saturates to a value of 0.04 to 0.06 and shows anisotropic behavior. In this connection, a critical review of the experimental results and the theoretical models of negative magnetoresistance ... -
Detection of charge-neutral modes to spin-wave excitations in graphene quantum Hall, and periodic magnetic field effect on Dirac electrons
In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically ... -
Deterministic Two Stage Clonal Expansion Model of Breast Cancer Epidemiology and its Utility for Optimal Screening Policies in India
Breast cancer (BC) has emerged as public health issue in India in last two decades sur-passing cervix cancer. Mortality from breast cancer is 30-40% higher than maternal causes. Breast cancer 5 year survival rates are ... -
Development and Characterization of Mercury Cadmium Telluride Colloidal Quantum Dot Based Infrared Optical Sensor
Motivation of this thesis is to synthesize HgCdTe quantum dots responsive in MWIR spectral range using chemical synthesis method and develop room temperature operated MWIR focal plane array using commercial silicon ROIC ... -
Development And Optimization Of A Microchip PCR System Using Fluorescence Detection
(2011-02-21)Microfabricated thermal cyclers for nucleic acid amplification by using polymerase chain reaction (PCR) have been demonstrated by several groups over the last decade, with improved cycling speed and smaller volumes when ... -
Development of a Spin-Polarized Low Energy Electron Diffraction System and Investigation on Spin-Orbit and Exchange Interactions on Ir(100) and Ultrathin Fe(100) Grown on Ir(100)
(2018-02-28)Spin-polarized electron beam has not yet been produced from an unpolarized electron beam using Stern-Gerlach type spin filter, because of the Lorentz force and Heisenberg uncertainty principle. At present, electron spin ... -
Development of data processing techniques for laser doppler velocimeter based flow measurements
Several schemes are available for conditional sampling of data on the velocity of a flowing fluid obtained in analogue form. These schemes are usually applied directly to the analogue data or to the digital data obtained ... -
Developments In Quantum Information Processing By Nuclear Magnetic Resonance
(2011-08-02)Residual dipolar couplings can be used to increase the number of qubits for quantum information processing. We have used molecules containing 3, 5 and 8 spins oriented in a liquid crystal matrix, and exploited the residual ... -
Developments in two dimensional NMR spectroscopy of multiple quantum coherences of couples spins in liquids
The pathway description provides a straightforward method of computing flip-angle dependence of various multiple quantum coherences in the 2D MQ and the 2D COSY spectroscopy. Using this flip-angle dependence it is possible ...
