HYPERNUCLEUS IN J-PARC E07 EXPERIMENT*	A single-? hypernucleus event which is detected in nuclear emulsion of J-PARC E07 experiment is analysed by applying relativistic kinematics. The ranges and position angles of charged particles tracks are calculated by using the position data supported by J-PARC E07 collaborators. The neutral particle emission at production point A and decay point B of single-? hypernucleus is checked by using the colinearity of two tracks and it is observed that, there is no neutral particle emission at point A but there is one or more neutral particles emission at point B. Charged particle track #4 is identified by its momentum and it is to be one of baryon families. The calculated results are compared with known experimental results. According to the analysis at point A, captured nucleus of ?- hyperon is identified as N 14 7 and the charged particle track #2 is identified as He 4 2 . At point B, single-? hypernucleus track #1 is identified as Be 10 ? and charged particle track #3 and #4 are identified as Li 6 3 and H 1 1 . In addition to charged particles emission, neutral particles are contaminated at point B.	2025
2402	Noe Noe Honey1, Saw Linn Oo2, Yin Maung Maung3	BOOST FOR MAINTENANCE OF MINI-SOLAR MODULES QUALITY DUE TO ACID RAIN*	The impact of acid rain on the potential induced degradation (PID) and subsequent recovery of mini-solar modules was investigated over varying durations. The acid rain with a pH of 4 was prepared and immersed mini-solar modules (12.5 cm x 7.2 cm) in it for 2, 4, and 5 days. The initial degradation of the mini-solar modules was assessed through photocurrent measurements under different lighting conditions. Following this, we subjected the modules to a recovery process, annealing them for 30 minutes at 50�C, and reevaluated their performance through photocurrent measurements. Additionally, the surface characteristics of these modules were explored using electroluminescence images during different daytime settings. This entire procedure was repeated for double degradation and recovery. Our experimental findings suggest that a simple low-temperature method can effectively restore degraded mini-solar modules to their original state.	2025
2403	Kaung Kyaw Naing1 and Ye Chan2	A COMPREHENSIVE STUDY ON SYNTHESIS, CHARACTERIZATION, AND ELECTROCHEMICAL PERFORMANCE OF PVA AND PAN DERIVED CARBON FIBERS FOR ENERGY STORAGE*	This research investigates the synthesis, characterization, and electrochemical performance of electrospun carbon fibers derived from Polyvinyl Alcohol (PVA) and Polyacrylonitrile (PAN) precursors under a nitrogen atmosphere. The electrospinning process produces nanofiber mats, which are subsequently carbonized in a nitrogen environment to form carbon fibers. Comprehensive characterization using Raman spectroscopy, Energy Dispersive X-ray Fluorescence (EDXRF), X-ray Diffraction analysis (XRD), and Scanning Electron Microscopy (SEM) elucidates their structural and elemental properties. The synthesized carbon fibers are then prepared for electrodes, and their electrochemical properties, including specific capacitances and energy densities are evaluated. This research seeks to determine the suitability of PVA and PAN based carbon fibers for advanced energy storage applications, potentially advancing the development of high-performance super capacitors and batteries for sustainable energy solutions	2025

According to the Sustainable Development Goal (SDG), water recovery from wastewater treatment has been emphasized for decades. In this study, ecofriendly adsorbents were prepared from disposable bamboo chopsticks waste to remove contaminants from laboratory and dye wastewater. Disposable bamboo chopsticks waste was collected from one of the restaurants around University of Magway. The adsorbents were prepared at 300 ? and 500 ?, respectively. For comparison, commercial activate carbon was used. The crystal structure of adsorbents was analyzed by X-ray diffractometer (XRD) and scanning electron microscopy (SEM) was used to observe morphology of the adsorbents. Energy dispersive X-ray fluorescence spectrometer (EDXRF) was used to study the elemental compositions of the adsorbents, initial and residual laboratory wastewater as well as dye wastewater. The dye removal percentages of prepared ecofriendly adsorbents were analyzed by ultraviolet-visible spectrophotometer (UV-vis). The results showed that the bamboo-based adsorbent prepared at 500 ? and commercial activated carbon performed higher removal in copper and zinc from laboratory wastewater, titanium, green and yellow colours from screen printing dye wastewater as well as methylene blue.	2025
