    Electromagnetic Polarization in Ionized Quantum Plasmas
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2024) Muhammad Bilal Rafiq; CIIT/FA22-RPH-011/LHR; Dr. Muhammad Jamil; LHR TP 9429
    This study investigates the influence of ionization dynamics on polarized electromag netic modes in quantum plasmas, an area crucial for various applications from astro physics to nanotechnology. By employing a Quantum Hydrodynamic Model (QHD) and numerical simulations with Mathematica, we aim to understand how ionization affects the polarization characteristics of electromagnetic waves. Despite its signifi cance, there’s a lack of comprehensive research on this topic. The QHD model, inte grating quantum effects like Bohm potential and Fermi pressure, provides a mathemat ical framework to analyze the behavior of these modes at the quantum scale. Through analytical and numerical approaches, we aim to interpret the interplaybetween plasma ionization and polarization, shedding light on fundamental aspects of quantum plasma dynamics

    Synthesis of iron doped nickel oxide (NiO) by Co- precipitation method
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Ayesha Liaqat , Asma Aziz; FA16-BPH-017 , FA16-BPH-047; Dr. Muhammad Idrees; LHR TP 5927
    The rapid development of nanotechnology and electronics during this period Ni was an interesting element because it is an oxidized form with semiconductor properties allows several applications, such as gas sensors, painted sensitized photocathodes and electrodes in alkaline batteries. In addition, NiO has recently been used as a resistor Switching (RS) is used as an electrochromic (EC) smart window that saves memory and energy. The study of the transition properties of NiO or Fe-doped NiO in resistive random cassation (RRAM) devices is easily possible using optical or magnetic techniques, so physical properties such as optical or magnetic properties are also of interest in this thesis. In this thesis study, the physical properties of NiO and Fe-Doped NiO were determined experimentally
