Our Cooperation Network

In 2016, Thailand adopted the Sustainable Development Goals (SDGs) for the period 2016-2030 under the auspices of the United Nations. With only 9 years left to achieve the SDGs, they have become a new agenda for global development, exerting pressure on the future production chain with a focus on economic, social, and environmental connections. The guiding principles, known as the 5Ps, encompass People, Planet, Prosperity, Peace, and Partnership. Driving sustainable development within Thailand's Sustainable Development Goals framework amid the global trend of borderless flows necessitates a sustainable stance adjustment in terms of roles and capacity development under global regulations to benefit the nation's people. Hence, cooperation from all sectors is crucial to execute collective actions efficiently. Prioritization and clear assignment of responsibilities among stakeholders are essential. As a research professional in Thailand, contributing to the strengthening of the country's fundamental research capabilities poses a significant role in driving the nation's potential. The development trajectory of Thailand will have a significant impact on the current global society. Thus, reform and adaptation to utilize the country's strengths and advantages to their fullest potential are imperative for national development.

Currently, electromagnetic waves are being utilized in various fields, with the type of application depending on the specific properties of the electromagnetic waves in each frequency range. One frequency range commonly used in applications related to biochemistry, biology, materials science, agriculture, food, and medicine is the infrared spectrum. This spectrum is divided into three frequency ranges: Near Infrared (NIR), Mid Infrared (MIR), and Far Infrared (FIR). Additionally, the Terahertz (THz) range is popularly used in spectroscopic experiments, with the MIR range being particularly significant due to its frequencies matching the molecular vibration fingerprint of various molecules, especially biomolecules. Hence, it is used to study molecular structures and interactions, particularly in biological and medical sciences. The Terahertz radiation frequency corresponds to rotational vibration in gas molecules, phonon vibration, and intraband relaxation in solids and semiconductors, making it suitable for studying electron excitation in materials for quantum applications. Furthermore, studying hydrogen bonds in gas and liquid molecules is crucial. Developing techniques and methodologies for the appropriate application of radiation in these frequency ranges, especially for cutting-edge research and advanced applications, which require radiation with special characteristics such as broad spectral range, high brightness, coherence, or short pulse length, is essential. Therefore, specialized radiation production processes, equipment, technologies, and experimental techniques tailored to the type of radiation application are necessary.

The application of radiation in these two mentioned frequency ranges has two main aspects: spectroscopy and imaging. Currently, there is a growing demand for spectroscopic experiments with samples in small quantities or liquid form, especially in the study of biomolecules and medical science. The development of radiation sources in both ranges and the techniques for measuring and applying radiation are rapidly evolving. Therefore, creating new knowledge from the interaction between mid-infrared and terahertz radiation with matter is crucial. In terms of imaging, terahertz radiation is commonly used due to its unique properties, such as the ability to pass through metals while reflecting when hitting metals and being absorbed when passing through water and liquids. This property allows for the differentiation of substances with different densities. However, there are several limitations to imaging in the terahertz range, such as signal attenuation in the air and the lack of equipment sensitive to high-resolution detection. Therefore, developing equipment and techniques to enhance the efficiency of using terahertz radiation for imaging materials under packaging is essential. This aligns with the main goal of the project proposal, which is to establish a collaboration network between institutions and research units specializing in the development, production, and measurement of infrared and terahertz radiation for spectroscopic and imaging research. This involves utilizing self-developed tools and techniques domestically and advanced tools internationally. In terms of tool development, three main aspects are emphasized: radiation production and transmission systems, experimental stations, and measurement and analysis systems for radiation signals. This includes the development of radiation transmission and reception devices and the development of imaging techniques using terahertz radiation.

Due to the ongoing development of the free-electron laser system, it will be the first of its kind in Thailand and ASEAN. The experimental station and experimental techniques that need to be developed will be unprecedented in the country. This poses a significant challenge for the research team, as they will need to gather experts from various fields, including particle acceleration, radiation production, optics, engineering, and researchers who apply free-electron lasers in various studies, including physics, chemistry, materials science, biology, biotechnology, astronomy, etc., from various organizations. This diversity is essential to provide a broad perspective and expertise. Additionally, it will enable the establishment of networks to leverage assistance from research groups or institutions abroad with expertise in this technology to collaborate in its development in Thailand.
