During the recent years, PM2.5 concentration is rising above the safety exposure limit in Thailand. PM2.5 could have originated from various sources such as exhaust fumes, open air burning, wildfire, etc. This concludes that all cities or places would have different PM source contributions. Most studies regarding the PM source findings were done based on chemical analysis. Our research team would like to predict the PM sources physically by nanostructures analysis. These methods would require the PM dust to be collected in a limited amount of time and dry. The use of paper filters may cause contamination from filter material which may cause errors in result evaluation. Our team suggests using Electrostatic Precipitator (ESP) where electrostatics is used to capture PM dust. This research mainly focuses on designing and building the ESP system for PM collection whereas the requirement is to collect at least 100 mg of PM dust within 1 day which would be adequate for nanostructure analysis. The study revealed that the customized ESP system could achieve of up to 80% collecting efficiency (which is more than the commercial ESP that we previously used), there’s a also a parametric study of relationships between flow velocity and collecting efficiency where collecting efficiency is inversely proportional to flow velocity. The suggested air velocity is not to exceed 2 m/s. However, there’re still more room for improvement of the ESP system for PM collection such as the convenience of PM collection process which resulted from the ESP construction geometry and sizes.
มลพิษทางอากาศนั้นส่งผลกระทบโดยตรงต่อสิ่งแวดล้อมและสุขภาพของสิ่งมีชีวิตทั้งในระยะสั้นและระยะยาว มลพิษทางอากาศนั้นสามารถจำแนกได้เป็นหลายกลุ่ม นั่นคือ มลพิษในรูปแบบสถานะแก๊ส ได้แก่ แก๊สโอโซน แก๊สไนโตรเจนออกไซค์ เป็นต้น และ มลพิษในรูปแบบของแข็ง ได้แก่ ฝุ่นละอองต่างๆ ซึ่งจะถูกจำแนกด้วยขนาดเป็นหลัก ในที่นี้ ฝุ่นละอองขนาดเล็ก (Particulate Matter) ตัวย่อ “PM” จะเป็นประเด็นสำคัญของงานวิจัยนี้เนื่องด้วยในปัจจุบัน สถานการณ์ฝุ่น PM2.5 ใน ประเทศไทยโดยเฉพาะภาคกลางและภาคเหนือ มีแนวโน้มที่จะรุนแรงขึ้นในฤดูหนาวของทุกปี

This study explores the design, production, and installation of 3D-printed modular artificial reefs (3DMARs) at Koh Khai, Chumphon Province, Thailand, through a design thinking framework. Collaborating with SCG Co., Ltd. and the Department of Marine and Coastal Resources, the research establishes design criteria and installation methods, utilizing content analysis and qualitative research. Key principles such as modularity, flexibility, environmental sustainability, and usability are identified. The user-centered approach optimizes the 3DMARs for transport and deployment, enabling local community involvement and fostering sustainable practices. The modular design supports scalability, enhancing marine habitats and coral larval settlement. Furthermore, underwater monitoring techniques enable site-specific data collection, allowing for the generation of digital twin models. This research offers a practical framework for marine ecosystem restoration and empowers coastal communities in Thailand and beyond

Air Rack is a product designed to address businesses with limited space and budget constraints for server rooms, cooling systems, and noise management. This system enables efficient use of IT equipment in open spaces, supporting both On-premise and On-cloud operations. It converts sensor data into digital information and displays it via a Dashboard, allowing users to monitor, analyze, and control the system remotely. Additionally, Air Rack significantly reduces power consumption and the costs associated with traditional server room management.
