This research intended to generate freshwater from seawater by desalination process using conventional single slope passive solar still. This work was carried out from 2023 March 31 to April 10 for 11 days. Freshwater 1061 ml was distilled from 2 L of seawater. Average freshwater productivity was 96.45 ml per day. Water quality assessment was conducted using a Horiba Multiparameter U-54G and Portable Multiparameter DO 110 to measure the physicochemical parameters such as temperature, electrical conductivity (EC), salinity, turbidity, total dissolved solids (TDS), pH, ORP, DO, and O2. Additionally, heavy metal constituents Cd, Cr, Pb, As, and Cu were analyzed with a Shimadzu (AA- 7000) Atomic Absorption Spectrophotometer. Results were compared with WHO�s drinking water quality standards, specifically National Surface Water Quality Standards in Myanmar, (NSWQS) Class II and Class V. The seawater exhibited all its quality parameters within the acceptable range of Class V. For both seawater and freshwater, the concentrations of Cd, Cr, and Cu fall within the WHO drinking water quality norms, but Pb and As slightly exceed permissible limits. The obtained freshwater meets Class II standards with a salinity of 0.02 ppt and a pH value of 7.41. From the point of view of freshwater quality, it is likely attributed to contaminants from solar still construction and the quality of the original seawater. Despite this, the freshwater parameters remain within class II permissible levels. Those findings contribute directly to targets 6.4 and 6.7 within SDG-6, which focus on efforts and initiatives related to water and sanitation. Consequently, this research can provide important access to fresh water for rural communities, while supporting an affordable and simple technology.	2025

In NAA method, the samples were activated by isotope Am Be (?, n) sealed neutron source. The strength of it is 550 mCi, with an average neutron energy of around 3 MeV, and a half-life of 432 years. After irradiation, the gamma-ray spectra of the samples were collected and analyzed using NaI (Tl) scintillation spectrometer. By NAA method, the iron content of hematite is 65.91%, limonite is 14.24%, and standard iron is 99.12%. NAA method is excellent to detect the mass concentration of iron in the samples.Iron raw materials, especially in small sizes, can be easily detected by NAA to ascertain their authenticity and iron content.	2025
2413	Wint Shwe War Hlaing1	A STUDY ON THE BENEFITS OF LIVING THINGS DUE TO PHYSICAL CHANGE IN MYANMAR TEA LEAVES	In many parts of the world, tea leaves are used for the health of the human and the growth of plants. The purpose of this paper is to study the concentration of elements that will come from the physical change of tea leaves and its effect on living things. In this study, the tea leaf samples were collected from the Shan state. The content concentration value of tea leaves in three stages of physical change is measured by EDXRF spectroscopy. It can be seen that the major nutrients for humans and plants are potassium and calcium. According to the measured values and calculated results, using a 250 ml cup, humans can drink 3-5 cups of green tea or 2-3 cups of black tea. It helps to reduce type II diabetes, cancer, and heart disease, and to improve the immune system. Not that much, the plants will survive in two weeks due to the supply of waste sludge of tea leaves and will grow for four weeks.	2025

ZnONPs powders were synthesized with three different ratios of Banana Peel:distilled water ( 2:10, 4:10, 6:10) and Zn(NO3)2.6H2O. The structural and morphological properties of the synthesized ZnONPs powders were characterized by XRD and SEM. The crystal structure of ZnONPS (2:10, 4:10, 6:10) were found to be hexagonal wurtzite structure and their crystallite sizes were 43.06 nm, 29.40 nm and 22.23 nm respectively which form irregular grains having sizes of 2.77 ?m, 2.39 ?m, and 2.22 ?m. ZnONPs (6:10) was deposited onto the fluorine doped tin oxide (FTO) substrates by using spin coating technique. Chlorophyll and Anthocyanin dyes solutions were extracted from Spinach Leaves and Grape Peel to use as sensitizer. ZnONPs substrates were dipped into two different natural dyes solutions, and natural dyes based ZnONPs photoelectrodes were prepared. The ZnONPs substrate, the natural dyes solutions and natural dyes based ZnONPs photoelectrodes were characterized by UV-Vis spectrophotometer. The energy band gap of ZnONPs substrate was found to be 2.48 eV. The optical band gap values were obtained 2.76 eV and 2.77 eV for Chlorophyll and Anthocyanin dyes solutions. Moreover, the optical band gap values of Chlorophyll and Anthocyanin based ZnONPs photoelectrodes were observed 2.63 eV and 2.49 eV respectively. According to obtained results, it can be reported that the two different natural dyes based ZnONPs photoelectrodes were suitable to use in DSSCs.	2025

The alpha particles are emitted from the well of the nucleus. Alpha spectroscopy is important role in the identification of radioisotope, radiation protection and radiation therapy in which alpha particle have the ability to deliver their energies to the target. In this research work, characteristics of ?-radiation in different density materials were investigated by using silicon semiconductor detector and ?-radiation sources: 241 Am and 226Ra. In the present study, the measurement of alpha spectroscopy was performed for the determination of ?-radiation characteristic such as energy loss, range, stopping power and effective path length not only in air medium but also in aluminum (Al) and gold (Au) foils samples of 8�m and 2�m respectively. Radionuclide Identification (RID) program is created in this research work. The measured spectra were analyzed by using this program based on the CASSY Lab and MATLAB software packages. Moreover, the experimental results data were compared with the theoretical calculated values by using Geiger Law, Bragg�s Law and Bethe-Bloch formula. The results data from the measurement were found in good agreement with the theoretical values less than 10%.	2025
