This research focuses on the design and development of a high-power converter to regulate energy supply from solar cells (Photovoltaic: PV) to a hydrogen production unit (Electrolyzer), which is a crucial component in advancing renewable energy in alignment with the RE100 initiative. Specifically, this study targets Green Hydrogen, which is generated through the water electrolysis process using clean energy from solar cells, ensuring zero emissions and environmental sustainability. The proposed converter includes of a Three-Level NPC Inverter, transformer, Full-Bridge Rectifier, and LC filter to enhance the power quality supplied to the electrolyzer. The system's design and simulation were conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Simulation was conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Additionally, a microcontroller-based control system is integrated with a gate driver circuit to optimize the electrolysis process by reducing power losses. This proposed converter effectively converts PV energy into suitable voltage and current levels for the electrolyzer while maintaining high hydrogen production efficiency.

In the world of blood donation, there are 2 types of people: those who donate blood and those who don't. Most campaigners emphasize how to persuade more people to donate blood and recruit more new blood donors. We believe that even though such focus is important, there're more critical aspects that might have been neglected, which is: for those who have already made up their minds to be blood doners, will they be successful in donating when the time comes? According to our studies, only 63 % of attempted doners are successful. Regrettably, 37 % has to go home disappointed as their bodies are not fit for the conditions required by Red Cross medical staff at blood donation centers (which include some most basic preparations such as low-fat food intake and 8-hours sleep on the night before). Our campaign, ‘Blood in Need, Buddy Indeed’, focuses on 2 aspects. Firstly, to persuade more people to donate blood. Secondly, for those who have made up their minds to donate blood, we will provide necessary support (both body and mind) so that they are fully prepared and successful in donating blood when the time comes via networks of systems, staffs and the newly designed and prototype of the application ‘Blood D’. Our campaign covers the whole ‘before/during/after’ experience of users (as blood doners). Support includes assessment of their current condition whether they are within the requirement of Red Cross Blood Bank. ‘Blood D’ will also provide relevant information on blood donating events, such as locations, and time booking. Once sign-up, the application “Blood D” will sent friendly reminder and clear infographic on how to prepare their bodies as daily notifications during the 7 days countdown. This is to ensure that the users’ blood will be ‘D’ (homophone of the Thai word ‘ดี’ which mean ‘good’ and at the same time playing on the word ‘ Buddy’) or be the ‘good blood’ that can save lives for those in need. After organizing 4 blood donation events both within and outside the KMITL. The numbers of successful blood doners have increased from 63 % to 78 % (this number is the average of 4 events, with the most successful event of 89%). The campaign has won the first runner up in national blood donation campaign competition. It is highly anticipated that once the application “Blood D” is fully launched, it will help increase the amount of blood collected up to 15% with the same numbers of existing doners.

The extreme weathers according to PM 2.5 is a global problem with out any borders. This pollutant can directly attack human health. The objective of the study was aimed to develop medicinal plant essential oil emulsions in order to use to decrease PM 2.5 based on chemical characterization of water-soluble anions and cations. A mount of 31 medicinal plant essential oil emulsions were prepared and then initially careened and tested for their efficiency in reducing PM 2.5 under test chamber by spraying method. It was found that spraying for 1 hr with kaffir lime essential oil emulsion at 0.025% concentration could reduce PM 2.5 obtained from engine exhaust pipe effectively when PM 2.5 of 24.7 µg/m3 was detected within 6 hrs, followed by kaffir lime essential oil emulsion at 0.05% and Eucalyptus essential oil emulsion at 0.05% and 0.025% concentration resulting in 27.3, 30.0 and 95.3 µg/m3, respectively. Whereas, water (blank) and control group (water and carboxymethylcellulose, CMC 0.2%) showed high revels of PM 2.5 with 126.4 and 157.3 µg/m3, respectively. This kaffir lime essential oil emulsion at 0.025% concentration showed 3-6 time decline of PM 2.5 upward 2 hrs compared with control group. Field experiment was performed at 3 Bangkok parks, namely, Suantaweewanarom, Suanbankharepirom and Suanthonbureerom. There were many factors affecting the decline of PM 2.5 caused by this essential oil emulsion, particularly, the windy as well as temperature and humidity. PM 2.5 level tended to be decreased after the beginning of spraying. In general, PM 2.5 levels appeared at those 3 parks were decreased rapidly within 1 hr as by average of 21.8 (7.7-27.3) µg/m3, Whereas, decline of only 6.4 (5.0-8.0) µg/m3 was observed in control (water). Incase of calm wind, (10-20 km/hr) this plant essential oil emulsion could even reduce PM 2.5 at 37.0-44.0 µg/m3 and reached to 13.5-16.5 µg/m3 within 3 hrs. As high level of PM 2.5 as 98.0-101.0 µg/m3 , it could reduce PM 2.5 to be an average of 23.0-26.5 µg/m3 within 3 hrs, Whereas, the use of water performed low capacity of PM 2.5 reduction found with only 31.0-40.0 µg/m3. However, windy condition (15-35 km/hr), the efficacy of this essential oil emulsion seem to be lower but tended to work better than using water alone
