Low Temperature Charge Transport And Magnetic Properties Of MWNTs/MWNT-Polystyrene Composites
(2014-11-19)
Carbon nanotubes (CNTs) have been recognized as potential candidates for mainstream device fabrication and technologies. CNTs have become a topic of interest worldwide due to their unique mechanical and electrical properties. ...
Experimental Studies Of Electron Spin Dynamics In Semiconductors Using A Novel Radio Frequency Detection Technique
(2015-08-05)
A novel experimental setup has been realized to measure weak magnetic moments which can be modulated at radio frequencies (~1–5 MHz). Using an optimized radio-frequency (RF) pickup coil and lock-in amplifier, an experimental ...
Warped Galaxies : Recovery Of Pattern Speed, Velocity Field And The Warp Equation
(2015-08-04)
Pattern speed is an important parameter of the density wave theory for spiral galaxies. In this thesis we have determined the pattern speed for warped galaxies (flat galaxies being a special case of this generalization) ...
Prolate Shaped Dark Matter Halo And The Galactic Warp
(2016-04-26)
The physical explanation for the existence of the galactic warp is one of the major research areas in Astronomy. People have proposed various theories but nobody has yet given a convincing explanation. Most of the spiral ...
Structural Studies on Thymidylate Kinase : Evolution, Specificity and Catalysis
(2018-05-30)
Thymidylate kinase (TMK) is a key enzyme for DNA synthesis. It occurs at the junction of the de novo and salvage pathways for the synthesis of deoxythymidine triphosphate (dTTP). Its inhibition affects cell viability, ...
Effects Of Disorder On Physical Properties Of Selected Transition Metal Oxides
(2013-02-14)
Disorder in materials often brings in new and exotic physical properties along with it. It is thus very important to study different kinds of disorder and their implications on various material properties. In this thesis, ...
One Dimensional Transport And Prospects Of Structural Transitions In Ultrathin Metallic Wires
(2013-02-25)
This thesis reports transport in ultrathin single crystalline nanowires of gold (∼ 2nm). These nanowires were fabricated using an oriented attachment process whereby nanoparticles of appropriate dimensions join in a linear ...
Optical Tweezers To Probe And Manipulate Soft, Nano And Bio Systems
(2013-01-31)
Statistical physics in soft matter systems, physical properties of bio-inspired systems and the mechanical manipulations of nano-systems have been studied using optical tweezers to form the basis of this doctoral Thesis. ...
