414 Khin Nyein Chan THE INVESTIGATION OF ELEMENTAL CONTENT IN WATER SAMPLES COLLECTED FROM YANGON REGION USING EDXRF AND AAS METHODS Energy Dispersive X-Ray Fluorescence Method for elemental concentration quantitatively and toxic and heavy elemental concentration were investigation by using Atomic Absorption Spectroscopy. The natural water samples were collected from artesian well in the eastern district of Yangon Region. The elemental concentrations were compared with the permissible standard levels and pH values were determined by using digital pH meter. The elemental contents were observed in the range as follows: Mn (0-0.394) ppm, Fe (0.028-0.236) ppm, Cu (0.031-0.076) ppm, Zn (0.025-0.505 ) ppm, As (0-0.002) ppm, Pb (0.047-0.080) ppm. Then, the comparison with World Health Organization guideline values were used. The concentration of the observed elements except Lead (Pb) were found to be within the acceptable levels. According to the pH value results, the artesian water from Thingangyun Township and Tamwe Township can be used as drinking water. 2019
415 Zaw Linn Htun COMPARATIVE STUDIES ON PURE MIXING AND MILLING-MIXING OF Y2O3-ZrO2/HAp BIOCOMPOSITE The milling-mixing Y2O3-ZrO2/HAp biocomposites have been investigated compared to the pure mixing ones to distinguish the effects of those two methods. The milling method reduced appreciably the particles size of the powders and resulting to better homogeneity and enhanced sinterability. The better densification process of HAp with ZrO2 favored to improve physical and mechanical properties of the biocomposite. The crystallized size of the milling-mixing samples was found to be 38.5 nm while pure mixing composite had a size of 46.2 nm. The former samples showed higher density than the latter ones in whole sintering temperature range (1050°C - 1250°C). Fine grains formation was also found in the milling-mixing samples. The highest flexural strength of 46.21 MPa and fracture toughness of 1.16 MPa.m1/2 were achieved by milling-mixing samples. The formation of apatite layer on the surfaces of Y2O3-ZrO2/HAp biocomposite samples also indicated the biocompatibility and potential bone forming ability. 2019
416 Khine Myint Zuu CHARACTERIZATION AND OPTICAL PROPERTIES OF THE COLEUS BLUMEI EXTRACT AS DYE SENSITIZED SOLAR CELLS (DSSC) The natural dyes used in this research were poinsettia leaves (Coleus Blumei).The absorbance and energy levels of dyes solutions were characterized using UV-Vis spectrophotometer and cyclic voltammetry. From UV-Vis absorption spectrum and , it was known that combination of anthocyanin and chlorophyll with ethanol was the broader region of the visible light spectrum in the range of 400 to 700 nm compared to extracted with methanol. All dyes were measured under the different solvents and temperatures to estimate the energy of the highest occupied molecular orbital (HOMO) and the energy of lowest unoccupied molecular orbital (LUMO). Optical band gap was measured from the absorption spectrum of each dye sensitizer. Fourier transform inferred (FTIR) was used to characterize the dye active components from 4000 to 500 cm-1. From FTIR results, the coleus blumei match with AMANO LIPASE (C11 H9 N3 Na O2) compound corresponding to the carboxylic acidic group in dye solutions were observed. 2019

419 Thinzar Lwin PREPARATION AND CHARACTERIZATION OF ACTIVATED CARBON DERIVED FROM RICE HUSK BIOMASS Rice husk was washed with distilled water to remove the contaminants present in the rice husk. The wet rice husk was dried at room temperature. The most important properties that provide information about the fuel were proximate such as moisture, ash content, volatile and fixed carbon contents. The fixed carbon content of rice husk biochar (RHB) was measured to be 10.3 mf wt%. The experiment was carried out to study the characterization of the rice husk ash. The rice husk biomass was heated at 300?C for 1h in muffle furnace and grounded into the uniform powder. Then, the carbonized material obtained was socked in 1M KOH, in 1:1 ratio for 24 h and followed physical activation at 300?C for 2h in muffle furnace. The structure characterization of activated carbon rice husk biochar (AC-RHB) was identified by X-ray diffraction (XRD) technique. The carbon C was observed by Energy Dispersive X-ray spectroscopy (EDXRF). The porous nature of AC-RHB was studied by scanning electron microscopy (SEM). The carbon C, O, and Si were observed by Energy Dispersive X-ray spectroscopy (EDX). The Fourier transform infrared spectroscopy (FTIR) analysis showed the presence of a variety of functional groups of AC-RHB. 2019
