Welcome Message from president of Chemical Society of Thailand
President of Chemical Society of Thailand
It is once again my honor to introduce the Pure and Applied Chemistry International Conference 2026 (PACCON 2026). This exciting event will be held from February 12–14, 2026, at the King Naresuan Exhibition and Convention Center (KNECC), Naresuan University, in Phitsanulok, Thailand.
The theme of PACCON 2026 is “The Global Future of Chemistry With AI”, reflecting the transformative role artificial intelligence continues to play in the chemical sciences. With this forward-looking theme, we are confident the conference will be as dynamic, engaging, and memorable as ever.
PACCON 2026 will feature plenary lectures, invited talks, oral and poster presentations by leading scientists, distinguished researchers, and promising early-career and young chemists from around the world.
A few words about the host city: Phitsanulok, located about 380 km north of Bangkok, was once the second capital during the Ayutthaya period and is rich in cultural heritage. Surrounded by beautiful natural reserves, it offers a unique blend of history and nature for visitors to explore.
We warmly invite you to join us and encourage you to mark your calendar for PACCON 2026. We look forward to welcoming you in Phitsanulok for an unforgettable experience.
Professor Dr. Vudhichai Parasuk
President of Chemical Society of Thailand
