Kasetsart University Doctoral Student Conducts Research Exchange at Uppsala University
10th March to 10th October 2025
at Uppsala University, Uppsala, Sweden
Ms. Donruedee Toyen, a doctoral student in the Nanomaterials Science program at the Department of Materials Science, Faculty of Science, Kasetsart University, participated in a seven-month research exchange program at The Tandem Laboratory, Uppsala University, Sweden, from 10 March to 10 October 2025. The Tandem Laboratory is an accelerator facility dedicated to radiocarbon dating and materials research. As a national research infrastructure, it serves academic, industrial, and public sectors through cutting-edge ion-beam-based research
During her stay, Ms. Donruedee conducted research on two main projects:
1. Trace element differences in fish cultivated in normal- and micro/nanobubble-treated waters
2. Improving the accuracy of trace element molarity measurements using spiked Optimal Cutting Temperature Compound (OCT). Her research involved the use of a scanning nuclear microprobe to map the distribution of elements and particles within samples. She also gained hands-on experience with GeoPIXE and LINAEUS software for PIXE, OA-STIM, and RBS data analysis, under the guidance of Prof. Harry J. Whitlow.
In addition, she contributed to a collaborative research project on trace element quantification in rapeseed in Lund, Sweden. Throughout the exchange period, Ms. Donruedee actively participated in various academic events, including workshops such as “Emergent Quantum and Spin Phenomena” and “Material Recycling”, as well as weekly seminars and group meetings.
This exchange provided valuable international research experience, fostered academic collaboration, and strengthened the ongoing partnership between Kasetsart University and Uppsala University in the field of advanced materials and radiation technology.
