This project aims to investigate and develop an energy storage system utilizing solar energy sources through the integration of solar cell technology and Graphene Quantum Dot Battery, representing a novel approach to enhancing energy storage efficiency and prolonging the lifespan of renewable energy systems. The selection of graphene and quantum dots as materials for battery development is attributed to their exceptional properties, including high electrical conductivity, charge storage capacity, efficient energy transfer, and enhanced stability.
การใช้พลังงานทดแทนจากแหล่งพลังงานแสงอาทิตย์ได้รับความสนใจเนื่องจากเป็นพลังงานสะอาดและยั่งยืน แต่การเก็บพลังงานที่ผลิตได้ในระหว่างวันยังคงมีข้อจำกัดในการใช้งานในช่วงกลางคืนหรือเมื่อพลังงานผลิตต่ำ การพัฒนาระบบกักเก็บพลังงานที่มีประสิทธิภาพสูงจึงมีความสำคัญเพื่อให้การใช้พลังงานแสงอาทิตย์เป็นไปอย่างยั่งยืนและมีประสิทธิภาพสูงสุด แบตเตอรี่กราฟีนควันตัมดอทมีคุณสมบัติเด่นในการเก็บพลังงานและการถ่ายโอนพลังงานอย่างรวดเร็ว โดยสามารถเพิ่มประสิทธิภาพและยืดอายุการใช้งานของแบตเตอรี่ได้ จึงเป็นทางเลือกที่ดีในการพัฒนาระบบกักเก็บพลังงานจากแสงอาทิตย์

This project aims to design and develop an eye-tracking system to facilitate communication for paralyzed immobile patients. The system is designed to enable patients to convey their needs to caregivers or family members by detecting and tracking eye movements using the Tobii Eye Tracker 5 device. This approach serves as an alternative communication method, replacing the physical movement or speech of paralyzed patients. The system effectively detects and tracks eye movements at a distance of 55 to 85 centimeters and is designed for installation on a computer to ensure ease of use. The program interface consists of three main sections: (1) a set of emotions, (2) a set of needs, and (3) a set of additional needs. It supports input from a virtual keyboard in both Thai and English and allows users to specify additional needs through eye-tracking-enabled typing. Furthermore, the system can generate synthetic speech for text that is difficult to pronounce aloud, send notification messages via the Line application, and store usage data in a database presented in a dashboard format. System testing revealed that the optimal detection distance ranges from 65 to 75 centimeters, as this range yields an error rate of no more than 1 percent. The system accurately responds to eye movements for communication through sound within 3 seconds when interacting with various function buttons. This eye-tracking system effectively enables paralyzed immobile patients to communicate their emotions and needs, facilitating better understanding and interaction between patients and their caregivers or family members.

Spent coffee grounds (SCG) are a byproduct of the coffee brewing process, and their quantity continues to increase due to the growing global coffee consumption. SCG contain beneficial compounds such as polysaccharides, dietary fibers, and antioxidants, which can be utilized in various applications, including prebiotic extraction. This study focuses on extracting prebiotics from SCG using acid hydrolysis and enzymatic hydrolysis methods to evaluate their potential in promoting the growth of beneficial gut microorganisms. The expected results of this research include adding value to coffee industry waste, reducing organic waste, and providing a sustainable approach to developing prebiotic products for use in the food and health industries. Furthermore, this study aligns with sustainable resource utilization and environmentally friendly practices.
