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 study investigated the effects of seed priming with Chaetomorpha sp. seaweed extract on seed germination and seedling growth of chili pepper. The objective was to examine the influence of seaweed extract concentrations on seed germination and seedling development. Seeds were primed in different concentrations of Chaetomorpha sp. extract, compared with a control treatment. The experiment was conducted using a completely randomized design with four replications. Results showed that seed priming with seaweed extract enhanced seed germination characteristics. Primed seeds exhibited improved germination percentage, germination index, and germination rate compared to the control. Additionally, seedlings from primed seeds showed enhanced root and shoot development. This study demonstrates the potential of Chaetomorpha sp. extract as a promising seed priming agent for improving chili pepper seed quality, which can be applied in the production of high-quality chili pepper seedlings.

This experiment aimed to study the suitable types of polymers for coating with chlorophyll extract and the quality of cucumber seeds after coating. The experiment was planned using a Completely Randomized Design (CRD) with four replications, consisting of five methods involving seeds coated with different types of polymers: Polyvinylpyrrolidone, Sodium Alginate, Carboxy Methyl Cellulose, and Hydroxypropyl Methylcellulose, each polymer being coated alongside chlorophyll, with uncoated seeds serving as the control method. The coating substance was prepared by extracting chlorophyll from mango leaves, then mixed with each type of polymer at a concentration of 1%, using an 8% concentration of chlorophyll extract. The properties of each coating method, such as pH and viscosity of the coating substance, were examined before coating the cucumber seeds with a rotary disk coater model RRC150 at a coating rate of 1,100 milliliters per 1 kilogram of seeds. Subsequently, the seeds were dried to reach the initial moisture level using a hot air blower, and seed quality was assessed in various aspects, including seed moisture, germination rate under laboratory conditions, germination index, and seed fluorescence under a portable ultraviolet light illuminator, as well as light emission spectrum analysis using a Spectrophotometer. The experiment found that each type of polymer could be used to form a film together with chlorophyll, which had appropriate pH and viscosity for the coating without affecting seed quality and showed fluorescence on the seed surface both under portable ultraviolet light and spectral emission analysis with a Spectrophotometer. Using HPMC as the film-forming agent with chlorophyll was the most suitable method, enhancing seed fluorescence efficiency.
