The CES-CHEM 2023 Meeting took place on December 7 and 8, 2023, in Bangsaen, Thailand, drawing over 50 participants from Thailand, Japan, South Africa, and China. The event featured dedicated sessions covering the realms of flow chemistry, sustainable chemistry, and digital-driven chemical process development. Additionally, three sessions were reserved for invited graduate students from Burapha University, VISTEC, Kyoto University, and Kyushu University. 

The opening ceremony on the first day commenced with greetings from Dr. Nayot Kurukitkoson, Dean of Engineering Faculty at Burapha University, and Mr. Shimazu Hideki, a JICA advisor. Dr. Sirin Chakamanont, an AUN/SEED-Net advisor, provided insights into the Research and Education University Consortium (REd-UC) grant, a key supporter of the CES-CHEM consortium.

Further, Associate Professor Dr. Nopphon Weeranoppanant, the leader of the CES-CHEM consortium, presented an overview of the organization's missions and activities, involving both academic and industrial members. The CES-CHEM 2023 Meeting was also co-sponsored by the KAKENHI "Low-entropy" project, as elucidated by Dr. Hiroyuki Miyamura from AIST (Japan).

Four distinguished keynote speakers have joined our event. Professor Paul Watts discussed his efforts towards flow synthesis of pharmaceutical active compounds, aimed at improving access to drugs for South Africans. Professor Kitakawa shared her advancements in super vitamin E production. Professor Jisong Zhang from Tsinghua University presented his recent study on micro packed bed reactors and the flow behaviors within them. Dr. Koichiro Masuda presented his work on catalyst screening and photochemical systems for oxygen activation.

Additionally, CES-CHEM members contributed to the event by discussing their ongoing research. For example, Professor Shusaku Asano emphasized the significance of mixing schemes, while Professor Yosuke Muranaka presented his research on microreactors for enantiomeric separation. Dr. Miyamura provided an overview of his work on heterogeneous catalysis in flow chemistry, and Dr. Charon Chinwanitcharoen presented his results on alcoholysis for biodiesel applications. Professor Hiromori shared insights into his modeling of adsorption columns.

Furthermore, representatives from our industrial partners delivered presentations. Dr. Yukako Asano, representing HITACHI, showcased efforts to scale up chemical production studied in microreactors. Representatives from EYELA introduced recent equipment applicable for flow chemistry. We also welcomed collaborators from Japan, with Professor Watanabe presenting his research group's work on the continuous-flow microparticle synthesis.

This event also served as a platform for graduate students (Masters and PhD) to present their research and receive feedback from other CES-CHEM consortium members. The presentations by graduate students covered diverse and intriguing topics, including bioprocesses, flow chemistry, and machine learning.
