Welcome Message from president of Chemical Society of Thailand

Professor Dr. Vudhichai Parasuk
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.

Welcome Message from acting president of Naresuan University

Assoc. Prof. Dr. Sarintip Tantanee
Acting President, Naresuan University

Dear Esteemed Participants, Distinguished Speakers, and Honored Guests,

It is my great pleasure to welcome all of you to PACCON 2026, the Pure and Applied Chemistry International Conference, held under the theme “The Global Future of Chemistry with AI.” This internationally recognized event, co-organized by The Chemical Society of Thailand and Naresuan University, takes place at the King Naresuan Exhibition and Convention Center (KNECC), within our university campus in Phitsanulok.

This year’s theme reflects an exciting and timely convergence between chemistry and artificial intelligence. AI is emerging as a transformative tool in chemical sciences, enabling faster discovery of green materials, intelligent design of sustainable synthesis pathways, and enhanced predictive models for environmental and health safety. As global challenges demand more urgent and innovative solutions, the integration of AI offers a pathway toward more efficient, sustainable, and responsible chemical innovations.

At Naresuan University, we are honored to host this important academic forum. As a comprehensive university with the vision to be a “University for Entrepreneurial Society,” we are committed to providing equitable education and building research capacity that meets the needs of the nine provinces of the Lower Northern region of Thailand. Our mission to become a frontier research university is supported by strong collaboration with public and private sectors, both nationally and internationally, in pursuit of social progress and regional economic stability.

PACCON 2026 exemplifies these values through its dedication to scientific excellence, global collaboration, and future-oriented innovation. With an impressive program of distinguished speakers, expert sessions, and networking opportunities, I am confident this conference will inspire meaningful dialogue and impactful partnerships that extend beyond the event.

Thank you for your participation. I wish you all a productive and rewarding conference and a pleasant experience in Phitsanulok.

Dear Esteemed Participants, Distinguished Speakers, and Honored Guests,

On behalf of the Organizing Committee, it is my great honor to welcome you to PACCON 2026, the Pure and Applied Chemistry International Conference, held under the inspiring theme “The Global Future of Chemistry with AI.” This year, we stand at a remarkable crossroads where the creativity of chemistry converges with the transformative power of artificial intelligence, offering us new ways to accelerate discoveries, design sustainable solutions, and address the urgent challenges of our time.

PACCON has long been recognized as a premier platform for scientists and innovators to exchange ideas, share breakthrough research, and build collaborations. In 2026, we are especially excited to open new dialogues on how AI can revolutionize our field—whether through the intelligent design of green materials, predictive modeling for health and environmental safety, or reimagining synthesis pathways for a sustainable future.

We are deeply grateful to The Chemical Society of Thailand, Naresuan University, our partners, and our dedicated organizing team, whose commitment and vision have made this event possible. Most importantly, we thank you—the researchers, educators, students, and industry leaders from around the world—for joining us in Phitsanulok to make this conference a vibrant, global forum for science.

I warmly encourage you to immerse yourself in the rich program of plenary lectures, technical sessions, and networking opportunities. Let PACCON 2026 be not only a platform for knowledge exchange but also a catalyst for meaningful dialogue, new collaborations, and enduring partnerships that will shape the future of chemistry in the era of AI.

“Welcome once again to Naresuan University, Phitsanulok, and welcome to PACCON 2026.”

Best regards,
