High Temperature Method Of Measuring Electrical And Magnetic Properties Of Europium Doped Nickel Oxide
The measurement of the magnetic moment of materials as a function of temperature in modern AC or DC magnetometers normally has a limited high temperature range up to 400 K. To overcome this problem one needs to design ... 
Electronic and Magnetic Properties of MAX Phase (Cr1xGdx)2AlC and Er3AlC Alloy
Bulk samples of (Cr1xGdx)2AlC with X = 0, 0.0025, 0.01, 0.025, 0.05 and Er3AlC compound were synthesized using the arc melting technique. The samples were characterized by Xray diffraction, magnetic susceptibility, and ... 
Resistivity of Single Crystal Molybdenum Dioxide
The chemical vapour transport method was used to grow molybdenum oxide single crystals so that their electrical properties could be analyzed. Satisfactory single crystal samples of MoO2 and Mo4O11 were grown successfully ... 
Deformations of Maxwell gauge field theory
Deformations of Maxwell gauge theory are studied in 2+1 dimensions. Unlike in previous work in the literature, no Lagrangian structure is assumed for possible deformations, and instead the requirement of gauge invariance ... 
Travelling Wave Solutions on a Nonzero Background for the Generalized Kortewegde Vries Equation
In presenting this thesis, we try to find all nonperiodic travelling waves of the generalized Kortewegde Vries (gKdV) equation u_t +\alpha u^p u_x +\beta u_{xxx}=0 using an energy analysis method. Since the power p ... 
An Analogue of the LaplaceRungeLenz Vector for Timelike Geodesics in Schwarzschild Spacetime
In Schwarzschild spacetime, the timelike geodesics are the trajectories of free, massive particles, orbiting a singularity at the origin r = 0. In this work we derive four scalar first integrals of timelike geodesics in ... 
Electronic and Magnetic Properties of Pyrochlore (Eu(1x)Dyx)2Ir2O7
The pyrochlore (Eu(1x)Dyx)2Ir2O7 for x = 0, 0.25, 0.50, 0.75, and 1.0 were prepared using solidstate reaction method. As the Dy concentration increases, the Xray results indicate a systematic decrease of the cubic ... 
Investigation into the Magnetoelectric Effect and Magnetic Properties of Irondoped Cobalt Molybdate
The plausibility of revealing linear magnetoelectric coupling is investigated in the cobalt molybdate (Co2Mo3O8). Recently, Wang et al.[Scientific Reports. 2015;Vol. 5:Article 12268] showed that iron molybdate(Fe2Mo3O8) ... 
A critical analysis of the 2H NMR data in chlorhexidinecontaining model membranes
Deuterium nuclear magnetic resonance spectroscopy was used to study the in uence of chlorhexidine on the internal molecular motions of phospholipid model membranes. Mixtures of dimyristoylphosphocholine (DMPC) and ... 
Effect of rattling Phonons on Superconductivity of KOs_2O_6
We model the electron coupling to anharmonic (rattling) mode in βpyrochlore superconductor KOs2O6 by a sharply peaked electronphonon coupling function α2F(Ω) centered at the mode energy. The strongcoupling Eliashberg ... 
Magnetic and Dielectric Properties of Cu3xNixWO6 and Cu3W1xMoxO6
Cu3WO6 is a compound with an interesting coordination chemistry for both Cu and W. In this research, all samples were made by using the standard Solid Phase Reaction method with and without any doping. Using Powder xray ... 
Numerical Solutions of Laplace's Equation for Various Physical Situations
There are two projects in this thesis. In the first project, a general method is introduced to numerically calculate the resistance of truncated resistors in cylindrical coordinates, with nonconstant crosssectional area. ... 
Infrared Spectroscopy Of Ba_3+y Co_1+xNb_2O_9 Ceramics
The dielectric properties of ceramic Ba3+y Co1+xNb2O9 where x= 0,0.07,0.03 and y = 0, 0.03 were characterized because it might used for a wide range of applications including wireless communication used in mobile ... 
Effect of Topological Morphology on Optical Filtering Properties of Porous Silicon
Macroporous silicon samples of differing topological porous properties were manufactured by way of electrochemical etching. Different etching parameters (etching current, time, electrolyte concentration) were used on four ... 
Preparation of Single Crystal Molybdenum Bronzes and Polycrystalline Rubidium Molybdenum Oxide
Lithium purple bronze (LiPB) Li0.9Mo6O17 was studied extensively in the 1980’s and has recently regained interest in the research community. The mechanism for the metalinsulator (M/I) transition at ∼25 K and superconductivity ...
