Quantum Theory of Mesoscopic Fractional Electric Fields in a Cavity of Viscous Medium

引用

World Journal of Condensed Matter Physics 2016年第1期6卷 39-44页

作者： saleem Iqbal Salma Jabeen Farhana Sarwar Syed mohsin Raza Department of Mathematics University of Balochistan Quetta Pakistan Department of Physics University of Balochistan Quetta Pakistan Department of Mathematics F. G. Girls Degree College Quetta Cantt Pakistan

With conjecture of fractional charge quantization (quantum dipole/multiple moments), Fourier transform stretching, twisting and twigging of an electron quanta and waver strings of electron quanta, the mathematical expressions for mesoscopic fractional electron fields in a cavity of viscous medium and the associated quantum dielectric susceptibility are developed. Agreement of this approach is experimentally evidenced on barite and Fanja site molecular sieves. These findings are in conformity with experimental results of 2012 Physics Nobel prize winning scientists, Serge Haroche and David J. Wineland especially for cavity quantum electro-dynamics electron and its associated mesoscopic electric fields. The mover electron quanta strings lead to warping of space and time following the behaviour of quantum electron dynamics.

Girls Degree College Quetta Pakistan Department of Physics Federal Urdu University of Arts Science and Technology Karachi Pakistan Department of Physics University of Balochistan Quetta Pakistan

Quantum theory with conjecture of fractional charge quantization, eigenfunctions for fractional charge quantization, fractional Fourier transform, Hermite function for fractional charge quantization, and eigenfunction for a twisted and twigged electron quanta is developed and applied to resistivity, dielectricity, giant magneto resistance, Hall effect and conductance. Our theoretical relationship for quantum measurements is in good conformity and in agreement with most of the experimental results. These relationships will pave a new approach to quantum physics for deciphering measurements on single quantum particles without destroying them. Our results are in agreement with 2012 Physics Nobel Prize winning Scientists, Serge Haroche and David J. Wineland.

SOLVENT QUALITY AND SOLUTION BEHAVIOR OF NYLON 12

引用

Chinese Journal of Polymer Science 2007年第5期25卷 483-490页

作者： Musa Kaleem Baloch Munaza Qayum mohsin Nawaz Sher Akber Department of Chemistry Gomal University Dera Ismail Khan Pakistan Department of Chemistry Balochistan University Queta Pakistan

The refractive index increment, dynamic and static laser light scattering, intrinsic viscosity [η] and Huggins constant （KH） of nylon 12 have been measured in m-cresol and sulphuric acid/water system at 10-60℃. The intrinsic viscosity, Rn, Rg, A2, and （〈 S 〉2）^1/2 （calculated from viscosity data） and ＂a＂ values of nylon 12 are found to be higher in m-cresol than in sulphuric acid. All these parameters decrease with the increase in water contents in sulphuric acid. The refractive index increment, KH and activation energy show an opposite trend to that of [η]. The intrinsic viscosity, RH, Rg, A2, and （〈 S 〉2）^1/2 have maximum values around 30-40℃ in sulphuric acid/water system, whereas in m-cresol they fall at about 20℃. It has been concluded that the variation in size, interaction parameter （second virial coefficient）, [η] and KH of the polymer solutions with the alteration in solvent composition and temperature are the out come of change in thermodynamic quality of solvents, selective adsorption, hydrogen bonding and conformational transitions. It has also been concluded that the increase in temperature first enhances the quality of the solvent, encourages hydrogen bonding and specific adsorption, and then deteriorates, bringing conformational transitions in the polymer molecules. However, the addition of water to sulphuric acid continuously deteriorates the solvent quality. This characteristic of the solvent system brings conformational changes in the polymer especially at low temperatures.

Liquid-phase aerobic oxidation of benzyl alcohol catalyzed by mechanochemically synthesized manganese oxide

引用

Chinese Science Bulletin 2013年第19期58卷 2354-2359页

作者： ILYAS Mohammad SIDDIQUE mohsin SAEED Muhammad National Centre of Excellence in Physical Chemistry University of Peshawar Department of Chemistry Government College University

Benzyl alcohol oxidation by molecular oxygen using solid manganese oxide as a catalyst and n-heptane as the solvent was studied in the liquid phase. The catalyst was synthesized by a simple mechanochemical process at room temperature and was characterized by different physical methods. The catalyst was highly active and 100% selective for benzyl alcohol conversion to benzaldehyde. The solid catalyst can be recovered from the reaction mixture by simple filtration and can be re-used. We found n-heptane to be an excellent solvent for the oxidation reaction, and that the catalyst did not leach into solution.

Application of Electrodynamic Theory on Quantum Hall Effect

引用

World Journal of Condensed Matter Physics 2016年第2期6卷 87-94页

作者： saleem Iqbal Muhammad Zafar Farhana Sarwar Syed mohsin Raza Muhammad Afzal Rana Department of Mathematics University of Balochistan Quetta Pakistan Department of Basic Sciences Riphah International University Islamabad Pakistan Department of Mathematics F. G. Girls Degree College Quetta Pakistan Department of Physics University of Balochistan Quetta Pakistan

The quantum electrodynamic (QED) behaviour is studied for quantum Hall effect (QHE). Quantum theory with conjecture of fractional charge quantization (quantum dipole moment), eigenfunctions for fractional charge quantization at the surface of a twisted and twigged electron quanta and above its surface, fractional Fourier transform and Hermite function for fractional charge quantization is developed. With energy eigen value equation for QHE and with energy operator on an eigenfunction of a twisted and twigged electron quanta, the corresponding eigenfunctions are normalized with Schrodinger’s quantum wave mechanical equation for electric scalar and magnetic potentials, respectively (QED behavior). The fractional electric and magnetic fields with their corresponding potentials for the quantized fractional states in semiconducting hereto structures are theoretically calculated. Such mathematical expressions are in good agreement with experimental results of Nobel Prize winning scientists Klitzing, Haroche, Peter and Gruebber. Our results can also explain the hybridized states of orbits with emphasis on sigma and pi bonding and their corresponding antibonding orbitals as a manifestation of electrophilic and nucleophilic chemical reactions.
