การใช้พลังงานทดแทนจากแหล่งพลังงานแสงอาทิตย์ได้รับความสนใจเนื่องจากเป็นพลังงานสะอาดและยั่งยืน แต่การเก็บพลังงานที่ผลิตได้ในระหว่างวันยังคงมีข้อจำกัดในการใช้งานในช่วงกลางคืนหรือเมื่อพลังงานผลิตต่ำ การพัฒนาระบบกักเก็บพลังงานที่มีประสิทธิภาพสูงจึงมีความสำคัญเพื่อให้การใช้พลังงานแสงอาทิตย์เป็นไปอย่างยั่งยืนและมีประสิทธิภาพสูงสุด แบตเตอรี่กราฟีนควันตัมดอทมีคุณสมบัติเด่นในการเก็บพลังงานและการถ่ายโอนพลังงานอย่างรวดเร็ว โดยสามารถเพิ่มประสิทธิภาพและยืดอายุการใช้งานของแบตเตอรี่ได้ จึงเป็นทางเลือกที่ดีในการพัฒนาระบบกักเก็บพลังงานจากแสงอาทิตย์

Metallic nanoparticles embedded in cellulose nanocrystal (MNPs/CNC) films were prepared by solution casting for antimicrobial and fungus in edible peel fruit. MNPs/CNC was synthesized by ultrasonic waves. The as-synthesized was characterized by the chemical characteristics by the transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction analysis (XRD), Fourier transform infrared spectrometer (FT-IR), zeta potential analyzer, and UV-visible spectrophotometer. MNPs/CNC films had high potential in antimicrobial and fungus. Therefore, MNPs/CNC can be used to wrap edible peeled fruit to inhibit the growth of microorganisms, which can effectively extend the shelf life of fruits.

This research suggested natural hemp fiber-reinforced ropes (FRR) polymer usage to reinforce recycled aggregate square concrete columns that contain fired-clay solid brick aggregates in order to reduce the high costs associated with synthetic fiber-reinforced polymers (FRPs). A total of 24 square columns of concrete were fabricated to conduct this study. The samples were tested under a monotonic axial compression load. The variables of interest were the strength of unconfined concrete and the number of FRRlayers. According to the results, the strengthened specimens demonstrated an increased compressive strength and ductility. Notably, the specimens with the smallest unconfined strength demonstrated the largest improvement in compressive strength and ductility. Particularly, the compressive strength and strain were enhanced by up to 181% and 564%, respectively. In order to predict the ultimate confined compressive stress and strain, this study investigated a number of analytical stress–strain models. A comparison of experimental and theoretical findings deduced that only a limited number of strength models resulted in close predictions, whereas an even larger scatter was observed for strain prediction. Machine learning was employed by using neural networks to predict the compressive strength. A dataset comprising 142 specimens strengthened with hemp FRP was extracted from the literature. The neural network was trained on the extracted dataset, and its performance was evaluated for the experimental results of this study, which demonstrated a close agreement.

The use of chemical herbicides in agriculture has raised concerns due to its adverse effects on farmers' health, environmental sustainability, and consumer safety. Paraquat, a widely used herbicide, has been banned in Thailand. In response to this issue, this research focused on the development of natural herbicide products as an alternative to conventional chemical herbicides. The study involved the extraction of bioactive compounds from selected plants with potential herbicidal properties and evaluating their effectiveness in controlling target weeds. The results indicated that the developed natural herbicide demonstrates significant weed control efficiency. Additionally, this product can be applied to organic farming systems, reducing reliance on hazardous chemicals and promoting sustainable agricultural practices. The development of this natural herbicide served as an essential step toward environmentally friendly and safe agricultural solutions.
