821 Aung Thu Lin CHARACTERIZATION OF GRAPHENIC MATERIAL COATED ON SAND FOR WATER PURIFICATION APPLICATION In this research, a suitable methodology was introduced to synthesize of graphenic material on sand as graphenic material coated sand composite (GSC). Graphenic material was prepared from sugar and normal sand as a media of adhesion in order to produce graphenic material coated sand media which is well known as graphenic material coated sand composite (GSC). GSC was used to remove lead from lead solution. Physical and chemical tests were carried out for water purification applications. Structural properties of the obtained composites were analyzed by X-ray diffraction (XRD) and the morphology studied of GSC was characterized by scanning electron microscopy (SEM). And then residual lead concentration of the lead solution after filtration process were observed by using atomic absorption spectroscopy (AAS). The current study reveals the importance of water purification application using GSC. 2020
822 San San Aye DESIGN AND CONSTRUCTION OF SOLAR PANEL CHARGING CONTROLLER The solar panel charging controlled system is designed and constructed using the microcontroller and light sensor. The design of solar panel charging controlled system consists of a mid-range PIC microcontroller (PIC16F877A), an alphanumeric liquid crystal display, a crystal oscillator and a 5V relay. The controller circuit was operated by a 5V dc power supply. Microcontroller checks the specified minimum and maximum voltage or less than voltage of battery. If the battery voltage is lower than the predetermined minimum or maximum voltage, battery is charged. If the battery voltage is greater than the maximum voltage, the charging circuit is cut off via relay. This can be saved the battery life span and prevent from the setting fire. 2020
823 Ni Lar SYNTHESIS AND CHARACTERIZATION OF TiO2 THIN FILMS BY SPRAY PYROLYSIS METHOD In this research work, anatase TiO2 sample was mixed with the methoxyethanol solution was used as the starting materials. The n type Silicon <100> plane was used as a substrate. The silicon substrate was annealed at 1000°C in furnace. The mixture solution was deposited on SiO2/Si substrate using spray pyrolysis- like method at different temperatures at 100°C, 200°C and 300°C respectively. The structural properties of TiO2/SiO2/Si films were analysed by XRD. The morphological properties of these films were determined by SEM. The optical properties of films were investigated by UV-Vis spectrophotometer. 2020
824 Su Su Tha PREPARATION AND STRUCTURAL PROPERTIES OF COPPER FERRITE BY SOL-GEL METHOD Copper ferrite materials were synthesized by sol-gel method. The X-ray diffraction (XRD) confirmed the phase formation and the structural characterization of these samples. The lattice parameter "a" of cubic structure was slightly decreased with increasing sintering temperature. The crystallite size of these samples was also evaluated. The grain size and grain boundary of ferrite samples were also analyzed by scanning electron microscope (SEM). 2020
825 Mg Mg Chit ANALYSIS OF PROTON SCATTERING FROM CARBON ISOTOPES Reaction cross section of carbon isotopes for proton scattering is computed with the wide incident energy region. Calculations are based on eikonal approximation which is a high energy (small scattering angle) that depends on the nucleon nucleus (NA) optical potential. The proton-carbon optical potential is obtained by a folding integral of the nucleon nucleon (NN) transition amplitude and matter density of carbon. Analytical formulas of optical potential are used to present in position-space representation for carbon isotope by using harmonic well nuclear densities(A<20). The eikonal phase function is presented in the momentum-space representation which is obtained from computing the fourier transform of the position-space optical potential in order to compare each other. 2020

828 Moht Moht Than JUNCTION FORMATION AND CURRNET TRANSPORT MECHANISMS IN TIN - DOPED CADMIUM OXIDE FILMS FOR TCO-Si BASED PHOTOVOLTAIC DEVICES APPLICATION Junction formation and current transport mechanisms of transparent conducting Sn doped CdO thin films on silicon (Si) substrate have been studied as a function of Sn doping concentration (0.15wt%, 0.20wt% and 0.25wt%). The samples have been investigated using current-voltage (I-V) and capacitance voltage (C-V) measurements in order to define the transport mechanisms in heterostructure and basic electronic parameters. From the current density - voltage, illuminated J-V measurement as well as the photovoltaic response extracted the solar cell parameters. The built-in potential, photo and dark saturation current at Sn doped CdO on p-Si interface are monitored varying Sn doping concentration. It is observed that a high built-in potential form at the Sn 0.25wt% doped CdO/p-Si junction. The current voltage characteristics were analyzed using Schottky and abrupt p-n junction models. The open circuit voltage Voc and saturation current density Jo extracted from the illuminated and dark J-V curves as well as calculated assuming a Schottky junction and an abrupt p-n junction for different Sn doping density ND. 2020
