The Department of Engineering Education at KMITL offers courses in power electronics laboratory practices, which require the use of expensive imported training kits. This results in a loss of national revenue due to the purchase of these imported kits. Therefore, the developers propose a power electronics training kit that offers equivalent or superior functionality to the imported ones while being more cost-effective, making it suitable for student experiments.
การเรียนการสอนรายวิชาอิเล็กทรอนิกส์กำลังในปัจจุบัน มีการใช้การจำลองการทำงานด้วยโปรแกรมคอมพิวเตอร์ เนื่องจากขาดแคลนชุดทดลองจริง ซึ่งการทดลองกับอุปกรณ์จริงยังมีจำเป็นเป็นอย่างยิ่ง ดังนั้นจึงมีการริเริ่มในการสร้างด้วยตนเองเพื่อให้สามารถนำมาใช้ในการเรียนการสอนได้

This research confirms the potential of bamboo fiber as a sustainable raw material for the textile industry, demonstrating exceptional properties that meet both functional requirements and environmental friendliness. The study focuses on integrating sustainability concepts with material innovation, encompassing fiber property analysis, production process development, and product design. The research objectives were to: 1) develop the properties of bamboo fiber for production; 2) study factors in designing environmentally friendly textile products from bamboo fiber; and 3) forecast future prospects for environmentally friendly textile product design using bamboo fiber. The findings revealed that 60-day-old bamboo possessed optimal properties for fiber separation, with an average fiber size of 5.32 μm, smaller than other natural fibers, resulting in superior moisture absorption and ventilation properties. When blended with recycled polyester fiber in a 30:70 ratio, the yarn exhibited strength and unique tactile characteristics. Although the antibacterial properties against Staphylococcus aureus were low, the fibers demonstrated excellent whiteness and softness. Factor analysis identified four key components in product design: Local Materials, Green Products, Healthy, and Sustainability. Consumer satisfaction evaluation of the prototype products showed high levels of acceptance, with the model explaining 84.7% of consumer satisfaction. The developed production process reduced chemical usage and hazardous waste. Furthermore, utilizing fast-growing bamboo minimized long-term environmental impact, contributing to sustainable development in Thailand's rural communities across economic, environmental, and occupational stability dimensions. The research demonstrates that developing bamboo fiber blended with recycled polyester creates sustainable products that meet consumer demands for health consciousness, local material utilization, and green product promotion. Commercial implementation of these products can enhance economic value and promote environmentally friendly product development in the future.

This study presents the development of carbon-based multiphase metal oxide nanocomposites (CNF@MOx; M = Ag, Mn, Bi, Fe) incorporating silver, manganese, bismuth, and iron nanoparticles within polyacrylonitrile (PAN)-derived carbon nanofibers. These nanocomposites were fabricated via the electrospinning technique followed by annealing in an argon atmosphere. The resulting nanofibers exhibited a uniform structure, with diameters ranging from 559 to 830 nm and embedded nanoparticles of 9-21 nm. Structural characterization confirmed the presence of various oxidation states of metal oxides, which play a crucial role in charge storage mechanisms. Electrochemical performance testing demonstrated that CNF@Ag/Mn/Bi/Fe-20 achieved the highest specific capacitance of 156 F g⁻¹ at a scan rate of 2 mV s⁻¹ and exhibited excellent cycling stability, retaining over 96% of its capacitance after 1400 charge-discharge cycles. The synergistic combination of electric double-layer capacitance and redox-based charge storage enhances the performance of these nanofibers as promising electrode materials for supercapacitor applications.
