The photoelectrochemical detection of salbutamol, which is illicitly used as a lean meat promoter in pigs, is investigated using a molecularly imprinted polymer (MIP)-based sensor with a CuO/g-C₃N₄ nanocomposite to enhance detection performance, leveraging nanomaterials and molecular imprinting for high selectivity and sensitivity. This approach offers a promising strategy for the precise and efficient analysis of salbutamol in food samples.

This study was conducted to develop a prototype cooling cover for transporting raw milk, aiming to provide a solution for maintaining the quality of raw milk during transportation to milk collection centers. The cooling cover is made using Phase Change Material (PCM), produced from water mixed with a gelling agent, in an amount of 5.6 kg, attached around an aluminum milk tank (with a capacity of 25 L). The cover is then covered with a UV-reflective fabric in two types: polyvinyl chloride (PVC) and high-density polyethylene (HDPE). The temperature reduction performance of both types of covers was evaluated by measuring water temperatures at various points along the radial and vertical directions of the milk tank at six points, using type-T thermocouples, under three environmental conditions: a constant temperature of 25 °C, 35 °C, and outdoor ambient temperature (average temperature 35.5 °C) for a minimum duration of 180 min. The experimental results revealed that at 120 min., the water in the tank covered with PCM-PVC and PCM-HDPE covers had temperatures lower than the ambient temperature by 12.6 °C and 12.9 °C, respectively, under a constant ambient temperature of 25 °C, and under a constant ambient temperature of 35 °C lower by 16.7 °C and 16.4 °C, respectively, and outdoor conditions. Since the temperature reduction performance of PCM-PVC and PCM-HDPE covers showed no significant difference, the performance of microbial quality preservation of raw milk was assessed only with PCM-PVC cover in comparison to a non-covered case (control), by measuring coliform and Escherichia coli counts using compact dry plates. Results indicated that after 120 min., milk in the tank covered with PCM-PVC had an average coliform count of 1.6 × 10^4 CFU/ml and E. coli count of 2 × 10^3 CFU/ml, which was lower than the non-covered control with an average coliform count of 1.5 × 10^4 CFU/ml and E. coli count of 1.1 × 10^4 CFU/ml. This study concludes that the temperature reduction achieved by the cooling cover can help inhibit coliform growth to levels below raw milk quality standards, demonstrating the potential of the cooling cover in maintaining the quality and safety of raw milk during transport, ultimately contributing to an improved quality of life for Thai dairy farmers.

This research project aims to study and develop a metaverse system for tourism in Horklong Subdistrict, Phitsanulok Province. The primary goal is to create a prototype metaverse system that showcases the cultural and historical tourist attractions in Horklong Subdistrict through virtual reality technology. This will help promote tourism in rural areas that are not yet widely known and enhance the modern promotion of tourist attractions in the province. The development of the metaverse system in this project utilizes virtual reality technology to simulate the experience of touring Horklong Subdistrict via a virtual boat ride. Users will be able to access the system through the Unity platform, which is a tool used to develop 3D and VR applications. The system is designed to allow users to choose to ride a virtual boat and visit various places that have been creatively recreated in a virtual format. These locations are designed and developed using 3D models based on real data collected from the Horklong Subdistrict area. This project is therefore an initiative to sustainably promote cultural and historical tourism in Phitsanulok Province. It has the potential to increase income for local communities as well as to disseminate local knowledge and wisdom to a broader audience. The metaverse system for tourism in Horklong Subdistrict is thus an important project in modernizing the province’s tourism sector and attracting more visitors, both domestically and internationally.
