SERDANG, 30 September 2025 – Universiti Putra Malaysia (UPM), through the Institute of Nanoscience and Nanotechnology (ION2), in collaboration with the Synchrotron Light Research Institute (SLRI), Thailand, has successfully conducted the second and third series of the UPM-SLRI Webinar Series under the theme “Seen the Unseen: XPS, XRF and XAS with Synchrotron Light.”

The second webinar series, held on 21 August 2025, featured Dr. Wutthikrai Busayaporn from SLRI, who delivered an engaging and insightful presentation on X-ray Photoelectron Spectroscopy (XPS) and X-ray Fluorescence (XRF). His clear explanations and strong technical expertise received highly positive feedback from participants, who actively engaged during the Q&A session to explore both theoretical and practical aspects of the techniques. Feedback from 33 attendees showed that 97% strongly agreed the session met its objectives and was beneficial to their research or academic pursuits. The same percentage expressed interest in future sessions, highlighting the strong enthusiasm for the series. Suggestions for upcoming topics included XPS data deconvolution, XRD analysis, BET surface area characterization, nanosensors, nanoparticle studies, and battery research. Participants also recommended compiling webinar materials into accessible notes or booklets for long-term reference.

The third series, organized on 4 September 2025, focused on X-ray Absorption Spectroscopy (XAS) and its applications in revealing structural and chemical details of materials beyond the reach of conventional methods. The half-day session featured Dr. Wutthikrai Busayaporn and Dr. Wanwisa Limphirat, both from SLRI, who shared theoretical insights and practical case studies on how XAS provides highly accurate measurements of X-ray absorption by specific atoms in a sample. The session attracted 23 participants, who contributed feedback and suggested future topics such as advanced nanotechnology applications, nanosensors, and techniques like Transmission Electron Microscopy (TEM) and Energy-Dispersive X-ray Spectroscopy (EDX).

The success of these two series underscores the relevance of synchrotron-based analytical techniques in advancing scientific research. According to ION2, the strong participation and constructive feedback reflect the importance of the UPM-SLRI collaboration in equipping researchers with cutting-edge scientific knowledge. Moving forward, the UPM-SLRI Webinar Series will continue to serve as a dynamic platform for knowledge exchange, international research collaboration, and capacity building in nanoscience, nanotechnology, and advanced materials research.
